SPECIFICATIONSGeneral DescriptionThe Palair Plus hoist is a lube-free* air powered hoist designedto lift and lower loads. The Palair Plus hoist may be hookmounted to the suspension shaft of a trolley or a permanentmounting structure. Using a fixed lug, hoist may also be mounteddirectly to a trolley. The air supply line can be strung to the hoistusing either hose hangers or hose trolleys.Palair Plus hoists are driven by a lube-free* gear motorconnected to a pinion shaft, and planetary reduction gear. Outputfrom the planetary reduction gear drives the load chain sprocket.Pinion shaft is also coupled to the brake discs. The brake isengaged at all times, until the hoist is powered in either the raiseor lower direction. System pressure acts on brake piston to releasethe spring-applied brake during hoist operation.Hoist top and bottom limit switches are integrated into the hoistbody and are activated by buffers attached to the load chain.Optional overload protection and emergency stop features aredesigned into the hoist motor assembly. Operation of theemergency stop feature is integrated into the hoist pendant.* Lube-free means that no lubrication to the supply air is requiredfor these hoists, and therefore no oil mist is exhausted to theatmosphere.NOTICE• This edition of the manual incorporates changes covered insupplement MHD56043SUP. Hoists with serial numbersending in letter E or with serial number 940100 and higher arecoveredbytheinformationinthismanual.The“DESIGNUPDATE SUMMARY” on page 54 is included to allow olderhoist versions to be repaired and upgraded.MHD56043 - Edition 3 5

INSTALLATIONPrior to installing hoist, carefully inspect it for possible shippingdamage.Hoists are supplied from the factory fully lubricated.Lubricate load chain before operating hoist.CAUTION• Owners and users are advised to examine specific, local orother regulations, including American National StandardsInstitute and/or OSHA Regulations which may apply to aparticular type of use of this product before installing orputting hoist to use.If trolley cannot be installed onto end of beam due to insufficientspace or fixed limit stops, trolley may need to be partiallydisassembled and installed from underneath beam.* Trolley Reference Table − Ingersoll-Rand TrolleysTrolley ModelPTTVP/TVGTIRSP/SGHoist Components (PAL1000K shown)Publication ReferenceMHD56102MHD56060MHD56083MHD56157WARNING• A falling load can cause injury or death. Before installing,read “SAFETY INFORMATION”.• The supporting structures and load-attaching devices used inconjunction with this hoist must provide adequate support tohandle all hoist operations plus the weight of the hoist andattached equipment. This is the customer’s responsibility. If indoubt, consult a registered structural engineer.MountingEnsure hoist is properly installed and personnel are trained in safeoperating procedures before placing hoist in service.Hook Mounted Hoist InstallationRefer to Dwg. MHP0239 on page 9. Place top hook overmounting structure. Ensure hook is large enough to properly fit onstructure. Make sure hook latch is engaged. Ensure the supportingmember rests completely within the saddle of the hook, and iscentered directly above hook shank. Hoist must freely hang fromhook without restriction.CAUTION• Supporting member must be positioned on the saddle of thehook.Ensurehoistdoesnottilttoonesideortheother.(Dwg. MHP0239)CAUTION• To avoid an unbalanced load which may damage the trolley,the hoist must be centered under the trolley. Refer to Dwg.MHP1537 on page 10.Trolley Mounted Hoist InstallationRefer to the trolley manufacturer’s installation manual*.Preadjust trolley width for beam flange measurement. Removerail stop and slide trolley onto end of beam. Reinstall rail stop.NOTICE• Trolley wheels ride on the top of the lower flange of thebeam.Always follow trolley manufacturer’s installation instructions.Typically the total clearance between the beam and trolley wheelflanges is 3/16 to 5/16 in. (4 to 8 mm) when trolley is installedcorrectly. Refer to Dwg. MHP1537 on page 10. The differencebetween dimensions ‘X’ and ‘Y’ equals the total clearance.MHD56043 - Edition 3 9

Hoist and Trolley AlignmentAirLineLubricator(optional)Refer to Dwg. MHP0191 on page 10. Palair Plus lube-free hoistsmay be operated without lubrication. If a lubricator is used,replenish daily and adjust to provide 3 drops per minute of ISOVG 100 (SAE 30W) oil (minimum viscosity 135 Cst at 104° F(40° C)) at maximum hoist operating speed.CAUTION• Shut off air supply before filling air line lubricator.(Dwg. MHP1537)When a trolley is used, check that the trolley side plates areparallel and vertical. Check hoist is centered below trolley. Useequal number of spacers on either side of hoist hanger. Raise aload equal to the rated capacity of the hoist 2-3 in. (50-75 mm) offthe floor and operate the trolley along the entire length of thebeam.Ensure beam stops are installed prior to operating trolley.Air SupplyThe air supply must be clean and free from moisture. A minimumof 90 psig (6.3 bar/630 kPa) at the hoist motor inlet is required toprovide rated hoist capacity.Air LinesThe inside diameter of the hoist air supply lines must not besmaller than 1/2 in. (13 mm) and 7/16 in. (11 mm) for hosefittings. For hoists with motorized trolley, or for supply lengthsgreater than 30 ft (9 m) the recommended hose diameter is 3/4 in.(18 mm). Before making final connections, all air supply linesshould be purged with clean, moisture-free air or nitrogen beforeconnecting to hoist inlet.Supply lines should be as short and straight as installationconditions will permit. Long transmission lines and excessive useof fittings, elbows, tees, globe valves, etc., cause a reduction inpressure due to restrictions and surface friction in the lines.(Dwg. MHP0191)Air Line FilterRefer to Dwg. MHP0191 on page 10.It is recommended that an air line strainer/filter be installedwithin 3 ft (1 m) of the motor to prevent dirt from entering themotor. The strainer/filter should provide 20 micron filtration andinclude a moisture trap. Clean strainer/filter periodically, asindicated by the operating environment, to maintain its operatingefficiency.Moisture in Air LinesMoisture that reaches the air motor through the supply lines is thechief factor in determining the length of time between serviceoverhauls. Moisture traps can help to eliminate moisture andother methods, such as an air receiver which collects moisturebefore it reaches the motor or an aftercooler at the compressorthat cools the air prior to distribution through the supply lines, arealso helpful.MotorFor optimum performance and maximum durability of parts,operate air motor within the operating specifications provided inthe “SPECIFICATIONS” section. The air motor should beinstalled as near as possible to the compressor or air receiver.10 MHD56043 - Edition 3

Overload Device (optional feature)Chain Container InstallationOverload protection is integrated into the motor body and isstandard on -E* versions. The overload system is based ondetection of the difference in air pressure between inlet and outletports. It consists of a valve which is normally closed. The valvesenses pressure at motor inlet and outlet and compares thedifference between the two pressures to the index valueestablished by spring adjustment. A difference in pressure greaterthan index value causes emergency stop to activate, exhausts airto atmosphere and stops hoist. Overload protection is factory presetto120%ofthesafeworkingload(SWL).* 1000K hoists provided in CE countries must be ordered withOverload Protection to maintain hoist rating.Without overloadprotection, hoists are derated to 980K units. Refer to ‘ModelCode Explanation’ in “SPECIFICATIONS” section on page 5.Load ChainEnsure chain is lubricated before operating hoist. UseIngersoll-Rand LUBRI-LINK-GREEN® or ISO VG 220 (50WSAE) oil.WARNING• Failure to maintain clean and well lubricated load chain willaffect life of chain resulting in premature wear and can causechain failure. If visual inspection indicates excessive chainwear inspect load bearings and sheaves. Refer to“INSPECTION” section.Chain ContainerRefer to Dwg. MHP1988 on page 11 and MHP2190 on page 50.CAUTION• Ensure chain container does not contact load chain or hook.• Do not pile chain carelessly in chain container. Piling chaincarelessly into container by hand may lead to kinking ortwisting that will jam the hoist.Run load chain to lowest point, attach chain container to hoist.1. Check chain bucket label to make sure length of load chain(195) is within capacity of chain bucket. Replace with alarger chain bucket, if required.2. Attach chain container to chain using capscrew, washer andnut or ‘S’ hook provided with container. Connect chain tohoist body using capscrew (29) and washer (38).3. Align holes in container with chain holder (54) and securewith capscrews (52).4. Run hoist in up direction to feed chain back into container.(Dwg. MHP1988)Limit Stop1. On hoists without a chain bucket, slide buffer and washeronto chain.2. Install limit stop as described under “Load ChainReplacement” in the “MAINTENANCE” section.3. Run hoist slowly in the “DOWN” direction to verify limitstop activates cutout.PendantRefer to Dwg. MHP1299 on page 12.1. Check all hose connections are tight and that hoses are nottwisted or crimped. Ensure hoses are correctly installed.WARNING• Disconnect air supply before performng any maintenance.MHD56043 - Edition 3 11

2. Check strain relief wire is firmly secured to hoist motor cover(5) and to pendant body with lifting eye (501).CAUTION• To avoid damaging pendant hose, make sure strain reliefcable, not pendant hose, is supporting weight of the pendant.Storing the Hoist1. Always store the hoist in a no load condition.2. Wipe off all dirt and water.3. Oil chain, hook pins and hook latch.4. Place in a dry location.5. Plug hoist air inlet port.6. Before returning hoist to service follow instructions for‘Hoists not in Regular Service’ in the “INSPECTION”section.(Dwg. MHP1299)12 MHD56043 - Edition 3

OPERATIONThe four most important aspects of hoist operation are:1. Follow all safety instructions when operating hoist.2. Allow only people trained in safety and operation on thishoist to operate the hoist.3. Subject each hoist to a regular inspection and maintenanceprocedure.4. Be aware of the hoist capacity and weight of load at alltimes.WARNING• Always operate, inspect and maintain this hoist inaccordance with any applicable safety codes and regulations.Operators must be physically competent. Operators should haveno health condition which might affect their ability to react, andthey must have good hearing, vision and depth perception. Thehoist operator must be carefully instructed in his duties and mustunderstand the operation of the hoist, including a study of themanufacturer’s literature. The operator must be aware of propermethods of hitching loads and should have a good attituderegarding safety. It is the operator’s responsibility to refuse tooperate the hoist under unsafe conditions.Initial Operating ChecksHoists are tested for proper operation prior to leaving the factory.Before the hoist is placed into service the following initialoperating checks should be performed.1. After installation of trolley mounted hoists, check to ensurehoist is centered below trolley.2. Check for air leaks in the supply hose and fittings topendant, and from pendant to motor.3. When first running hoist or trolley motors, a small amount ofnon-detergent, light oil should be injected into inletconnection to allow good lubrication.4. When first operating hoist and trolley it is recommended thatmotors be driven slowly in both directions for a few minutes.5. Operate trolley along the entire length of beam.6. Check operation of limit devices.7. Check that trolley (if equipped) and hook movement aresame direction as arrows or information on pendant control.8. Check hoist is securely connected to overhead crane,monorail, trolley or supporting member.9. Check load is securely inserted in hook, and that hook latchis engaged.10. Raise and lower a light load to check operation of hoistbrake.11. Check hoist operation by raising and lowering a load equalto the rated capacity of hoist a few inches (centimeters)above floor.12. Check hoist is directly above load. Do not lift load at anangle (side pull or “yard”).13. Inspect hoist and trolley performance when raising, movingand lowering test load(s). Hoist and trolley must operatesmoothly and at rated specifications prior to being placed inservice.WARNING• Only allow personnel trained in safety and operation of thisproduct to operate hoist and trolley.• Hoist is not designed or suitable for lifting, lowering ormoving persons. Never lift loads over people.• The hook latch is intended to retain loose slings or devicesunder slack conditions. Caution must be used to prevent latchfrom supporting any of the load.Hoist ControlsHoist operation is controlled by either pendant or rope (chain)control. Careful movement of pendant levers or rope (chain) willallow infinitely variable up and down speeds. Hoists supported bya powered trolley require a four lever pendant control.PendantsPendants allow operator to remotely control the positioning ofloads from a distance, thereby allowing exact positioning of theload in a controlled and efficient manner.The two lever pendant is the standard pendant provided with thePalair Plus hoist and is designed to provide hoist operation only.The pendant control throttle uses two separate levers for hoistoperation. Direction of hook travel is controlled by whicheverlever is depressed. Refer to Dwg. MHP1649 on page 13.1. To operate hoist, press the “UP” or “DOWN” control lever.Hoist speed is determined by amount lever is depressed.Depress operating lever as necessary to achieve desiredoperating speed.2 Lever Pendant (shown with optional Emergency Stop)(Dwg. MHP1649)Four lever pendants provide a single station for operation of hoistand a motor driven trolley.The pendant control throttle uses the two inside levers for hoistoperation and the two outside levers for trolley operation.Direction of travel is controlled by whichever lever is depressed.Refer to Dwg. MHP1547 on page 14.MHD56043 - Edition 3 13

INSPECTIONWARNING• All new or repaired equipment should be inspected andtested by personnel trained in safety, operation andmaintenance of this equipment to ensure safe operation atrated specifications before placing equipment in service.• Never use a hoist that inspection indicates is damaged.Frequent and periodic inspection should be performed onequipment in regular service. Frequent inspections are visualexaminations performed by personnel trained in safety andoperation of this equipment and include observations made duringroutine equipment operation. Periodic inspections are thoroughinspections conducted by personnel trained in safety, operationand maintenance of this equipment. ASME B30.16 statesinspection intervals depend upon the nature of the criticalcomponents of the equipment and the severity of usage.Careful inspection on a regular basis will reveal potentiallydangerous conditions while still in the early stages, allowingcorrective action to be taken before the condition results in ahazard.Deficiencies revealed through inspection, or noted duringoperation, must be reported to designated personnel trained insafety, operation and maintenance of this equipment. Adetermination as to whether a condition constitutes a safetyhazard must be decided, and the correction of noted safetyhazards accomplished and documented by written report beforeplacing the equipment in service.Frequent InspectionOn hoists in continuous service, frequent inspection should bemade at the beginning of each shift. In addition, visualinspections should be conducted during regular service forevidence of any damage or malfunction.1. OPERATION. Check for visual signs or abnormal noises(grinding etc.) which could indicate a problem. Make sure allcontrols function properly and return to neutral whenreleased. Check chain feed through the hoist and bottomblock. If chain binds, jumps, is excessively noisy or “clicks”,clean and lubricate the chain. If problem persists, replace thechain. Do not operate hoist until all problems have beencorrected.2. UPPER AND LOWER LIMIT DEVICE. Test operation withno load. Upward travel must stop when stop buffer on chaincontacts hoist limit switch.3. HOOKS. Check for wear or damage, increased throat width,bent shank or twisting of hook. Replace hooks with 15%increase in throat width. Refer to Dwg. MHP0040 on page15. Replace hooks with 10° twist. Refer to Dwg. MHP0111on page 15. If the hook latch snaps past the tip of hook, thehook is sprung and must be replaced. Replace BullardBurnham hooks if the gate no longer contacts the hook tip.Refer to Dwg. MHP0662 on page 16. Review the latestedition of ASME B30.10 “HOOKS” or additionalinformation. Check hook support bearings for lubricationand indication of wear or damage. Ensure they swivel easilyand smoothly.Records and ReportsInspection records, listing all points requiring periodic inspectionshould be maintained for all load bearing equipment.Writtenreports, based on severity of service, should be made on thecondition of critical parts as a method of documenting periodicinspections. These reports should be dated, signed by the personwho performed the inspection, and kept on file where they arereadily available for review.(Dwg. MHP0040)NOTICE• During assembly/disassembly visually inspect eachcomponent for distortion, wear and damage. Replace itemsindicating damage, distortion and/or excessive wear. Properuse, inspections and maintenance will increase the life andusefulness of your Ingersoll-Rand equipment.Load Chain ReportRecords should be maintained as part of a long-range load chaininspection program. Records should include the condition of loadchain removed from service. Accurate records will establish arelationship between visual observations noted during frequentinspections and the actual condition of load chain as determinedby periodic inspections.(Dwg.

LUBRICATIONLubrication ScheduleTo ensure continued satisfactory operation of the hoist, all pointsrequiring lubrication must be serviced with the correct lubricant atthe proper time intervals indicated for each assembly. Correctlubrication is one of the most important factors in maintainingefficient operation.The time intervals recommended in Table 3 are based on hoistintermittent operation of the hoist eight hours each day, five daysper week in a normal environment. If the hoist is operated almostcontinuously, or for more than eight hours each day, or undersevere (dirt, chemical fumes, etc.) conditions, more frequentlubrication will be required.Table 3ComponentLubrication Frequency by Usage LevelSevere Heavy NormalGeared TrolleyWheelsMonthly Quarterly YearlyLoad Chain Daily Weekly When UsedHook and HookLatchDaily Weekly When UsedGear Case Yearly Every 3 Years UnnecessaryLubricant types and change intervals are based on operation in anenvironment relatively free of dust, moisture and corrosive fumes.Use only those lubricants recommended. Approval for the use ofother lubricants must be obtained from your Ingersoll-RandTechnical Support Department or distributor. Failure to observethis precaution may result in damage to the hoist and/or theassociated components.Whenever a hoist is disassembled for overhaul, inspection orreplacement of parts, lubricate as follows.Load ChainWARNING• Failure to maintain clean and well lubricated load chain willresult in rapid load chain wear that can lead to chain failurewhich can cause severe injury, death or substantial propertydamage. If visual inspection indicates excessive chain wearinspect sprocket and chain wheel. Refer to “INSPECTION”section on page 15.1. Lubricate each link of load chain weekly. Apply newlubricant over existing layer.2. In severe applications or corrosive environments, lubricatemore frequently than normal.3. Lubricate hook and hook latch pivot points with samelubricantusedonloadchain.4. If required, clean chain with acid free solvent to remove rustor abrasive buildup and lubricate the chain.5. Use Ingersoll-Rand LUBRI-LINK-GREEN® or ISO VG220 (SAE 50) EP oil.Gear CaseThe gear case is packed with grease on assembly.Whenever hoist is serviced, remove old grease and replace withnew. Use a good quality EP2 grease with a dropping point of 302°F (250° C) with minimum viscosity 1100 SSU at 100° F (38° C).CAUTION• Amount of grease in gear case must not exceed 2 ounces (60grams).Air Line LubricatorIf equipped, the air line lubricator should be replenished daily andset to provide 3 drops per minute of ISO VG 100 (SAE 30W) oilwith minimum viscosity 135 Cst at 104° F (40° C) at maximumhoist operating speed.Hook and Hook Latch1. Lubricate hook and hook latch pivot points. Hook and latchshould swivel/pivot freely.2. Use Ingersoll-Rand LUBRI-LINK-GREEN® or ISO VG220 (SAE 50) EP oil.3.

Overload DeviceLoad ChainRefer to Dwg. MHP1302 on page 22 and MHP2192 on page 36.NOTICE• Do not change factory settings. If overload requiresadjustment as a result of repair, it is recommended thatsettings be adjusted and certified at an authorized repairfacility.Overload is factory preset at 20% above hoist rated safe workingload (SWL). Do not set overload for quantities greater than thissetting. The overload spring tension determines pressure at whichoverload activates to stop hoist operation. Increase spring tensionto raise overload setting; decrease to lower overload setting.To adjust setting use the following procedure:1. Attach a certified test load (not to exceed 20% maximum ofthe SWL) to hoist. Operate hoist in raise direction. Ifoverload is properly adjusted, load should not raise, hoistshould not operate.2. To adjust, loosen locknut (153) and turn adjusting screw(151) as necessary to increase or decrease the SWL. Turningadjusting screw clockwise increases SWL setting;counterclockwise decreases SWL setting. It is recommendedthat minor adjustments to setting be made, the locknut beengaged and hoist tested. Repeat adjustments as required.NOTICE• When hoist does not shut off, and load raises, the overloadSWL has been exceeded. Back adjusting screw(counterclockwise direction) out 1/4 turn and recheck.3. When completed, ensure locknut is tight and check hoistoperation at rated load.Overload AdjustmentMakinga‘C’LinkCAUTION• When cutting weld side of a chain link, do not cut or nickopposite side. A damaged link must be replaced to preventpremature failure. A falling chain can cause injury.1. Using an abrasive wheel or hacksaw, cut a section from weldside of first or last link of chain as shown in Dwg. MHP0817to the dimension shown in ‘C’ Link Dimension Table. Use a‘C’ link which is the same size as the chain being replaced.(Dwg.

To reinstall loadchainonhoiststhathavebeenreassembledaftermaintenanceor repair refer to ‘Load Chain Installation’ on page 28.• On PAL1000K (double fall) hoists the total number of chainlinks must be an even number to ensure chain is not twisted.• Prior to installing new load chain, ensure chain is properlylubricated. Refer to “LUBRICATION” section.(Dwg. MHP1302)CAUTION• Welds on load chain can damage hoist sprocket and hookblock wheel. Ensure chain welds locate away from hoistsprocket and double fall block wheel. Refer to Dwg. MHP0267on page 23.22 MHD56043 - Edition 3

It may not be possible to detect chain wear by casual observation.Chain is case hardened and once the case hardening is wornthrough, wear will progress rapidly and the strength of the chainwill be considerably reduced. Further, the chain will no longer fitcorrectly in the chain sprocket or block wheel, greatly increasingthe chance of malfunction and chain breakage.The chain sprocket and block wheel will outlast several loadchains if chain is inspected and replaced as recommended. Use ofa worn chain will cause sprocket and block wheel to wear rapidly.If chain is visibly damaged, inspect chain sprocket, chain guideand block wheel. Replace worn parts.1. Hoist must be installed and connected to air supply. Reduceair pressure to 60 psi (414 kPa/4 bar).2. Remove chain bucket, if used.3. Remove hook.a. On single fall hoists refer to Dwg.

General DisassemblyThe following instructions provide the necessary information todisassemble, inspect, repair, and assemble the hoist. Partsdrawings of hoist assembly are provided in Parts Section. If ahoist is being completely disassembled for any reason, follow thetopic order as presented.It is recommended that all maintenance work on hoist beperformed on a bench in a clean dust free work area. In the processof disassembling hoist, observe the following:1. Never disassemble hoist any further than is necessary toaccomplish needed repair. A good part can be damagedduring the course of disassembly.2. Never use excessive force when removing parts.Tappinggently around perimeter of a cover or housing with a softhammer, for example, is sufficient to break seal.3. Do not heat a part with a flame to free it for removal, unlessthe part being heated is already worn or damaged beyondrepair and no additional damage will occur to other parts.In general, the hoist is designed to permit easy disassembly andassembly. The use of heat or excessive force should not berequired.4. Keep work area as clean as practical, to prevent dirt and otherforeign matter from getting into bearings or other movingparts.5. All seals and ‘O’ rings should be discarded once they havebeen removed. New seals and ‘O’ rings should be used whenassembling hoist.6. When grasping a part in a vise, always use leather-coveredor copper-covered vise jaws to protect surface of part andhelp prevent distortion. This is particularly true of threadedmembers, machined surfaces and housings.7. Do not remove any part which is press fit in or on asubassembly unless removal of that part is necessary forrepairs or replacement.DisassemblyNOTICE• Prior to disassembly, check the serial number of hoist.

Cleaning, Inspection and RepairUse the following procedures to clean, inspect, and repaircomponents of the hoist.CleaningCAUTION• Bearings that are loose or worn must be replaced. Failure toobserve this precaution will result in additional componentdamage.• Do not use trichloroethylene to clean parts.Clean all hoist component parts in solvent (except for the brakedisc). Use of a stiff bristle brush will facilitate removal ofaccumulated dirt and sediments on gears and frames. If bushingshave been removed it maybe necessary to carefully scrape oldLoctite® from bearing bores. Dry each part using low pressure,filtered compressed air. If brake friction disc is oil soaked, it mustbe replaced.InspectionAll disassembled parts should be inspected to determine theirfitness for continued use. Pay particular attention to thefollowing:1. Inspect all gears for worn, cracked, or broken teeth.2. Inspect all bushings for wear, scoring, or galling.3. Inspect shafts for ridges caused by wear. If ridges caused bywear are apparent on shafts, replace shaft.4. Inspect all threaded items and replace those having damagedthreads.5. Inspect brake friction disc for oil. If brake friction disc is oilsoaked, replace brake friction disc. If brake friction disc isglazed, sand it lightly using fine emery cloth.6. Measure thickness of brake friction disc. If brake frictiondisc (88) is less than 0.098 in. (2.5 mm), replace.7. Check screen (33), filter (3) and silencer (37) for damage orclogging caused by excessive dirt.RepairActual repairs are limited to the removal of small burrs and otherminor surface imperfections from gears and shafts. Use a finestone or emery cloth for this work.1. Worn or damaged parts must be replaced. Refer to theapplicable Parts Listing for specific replacement partsinformation.2. Inspect all remaining parts for evidence of damage. Replaceor repair any part which is in questionable condition. Thecost of the part is often minor in comparison with the cost ofredoing the job.3. Smooth out all nicks, burrs, or galled spots on shafts, bores,pins, or bushings.4. Examine all gear teeth carefully, and remove nicks or burrs.5. Polish the edges of all shaft shoulders to remove small nickswhich may have been caused during handling.6. Remove all nicks and burrs caused by lockwashers.AssemblyNOTICE• Prior to assembly, check serial number of hoist.
