Service ManualGeneralIntroductionThis service manual is part of the instructions and contains the technicalinformation for servicing, configuring and repairing a Küschall® wheelchair.To guarantee the required safety and reliability, all wheelchairs must becomprehensively checked once a year.In part, assembly and adjustment require extensive experience. For thisreason, the following assembly instructions have been split into threecategories:RequirementEasy – technical understanding requiredMedium – technical knowledge requiredDifficult – technical knowledge and expertise inassembling wheelchairs requiredSymbol•◦◦••◦•••GLSBThe required tools and their respective sizes are listed above each instruction.The instructions include information on the torques with which therespective screw connections must be tightened. Adhering to the giventorques requires the use of a torque spanner.ToolSymbolAllen key à 3, 4, 5, 8Phillips screwdriver Ò 2GBOpen-end spanner 8, 10, 11, 19Socket spanner/Box spanner 8, 10Spare parts and adaptationsAll spare parts may be obtained from the Küschall® customer service department.An electronic spare parts catalogue can be found atwww.kueschall.com. Only original spare parts may be used. The writtenauthorisation of Küschall® AG must be obtained before installing additionaladaptations on a Küschall® wheelchair.Fastening with hexagon socket boltsHexagon socket bolts are not designed to withstand an excessive applicationof force. When tightening or undoing a hexagon socket bolt, forcemust be applied to the nut wherever possible to avoid damaging the bolt.Tightening and undoing Turn the nut using a socket spanner (only use an open-end spanner ifthere is insufficient space), using the Allen key simply to stop the boltturning.Tightening and undoing when no nut is presentIf a hexagon socket bolt is screwed directly into a thread, the bolt must betightened using the Allen keyiEnsure that the Allen key is of good qualityand not worn.4 © Küschall AG, Schweiz | 2011-12


Service ManualTorque All bolts must be tightened with the torque specified in the following instructions.ChecksVisual check Check the entire frame for cracks, especially in the vicinity of joints and weld seams.Check of the bolts Check that all bolts have been tightened with the torque specified in the instructions.jjSeveral bolts are secured with adhesive. If these are loosened, they have to be cleaned andsecured with adhesive again.Self-locking nuts and screws, once loosened, have to be replaced by new ones.Identifying and repairing faultsFault Possible cause ActionIncorrect tyre pressure on one rearwheelCorrect tyre pressureThe wheelchair does nottravel in a straight lineThe wheelchair tips tooeasilyThe brakes are grippingpoorly or asymmetricallyOne or more spokes brokenSpokes tightened unevenlyFront wheel bearings are dirty ordamagedBackrest angle too largeWrong seat positionIncorrect tyre pressure in one or bothrear tyresBrake setting incorrectTyre pressure in rear tyres is too lowReplace broken spoke(s)Tighten loose spokesClean or replace the bearingsReduce backrest angleChange seat positionCorrect tyre pressureCorrect brake settingCorrect tyre pressureThe rolling resistance is veryhighThe front wheels wobblewhen moving fastThe front wheel is stiff orstuckRear wheels are not parallelFront wheel axles are restrained by dirtor hairBearings are dirty or faultyToo little tension on the clevis pinhousingFront wheel is worn flatBearings are dirty or faultyMake rear wheels parallelClean front wheel axlesReplace the bearingsTighten the nut on the castor forkslightlyReplace front wheelReplace the bearings5 © Küschall AG, Schweiz | 2011-12


Service ManualSeatSeatSeat width (SB)Available seat widths: SB 340 to SB 440, in 20 mm steps.Once it has been set the seat width cannot be modified easily. It requires replacing the seat module,possibly the centerpart, the backrest, axle and possibly the footrest. This modification is not describedin the service manual.Seat depth (ST)Available seat depths: ST 375 to ST 475 in 25 mm steps.Adjusting the seat depth requires replacing the entire seat module including seat upholstery andrail, as well as the seat cushion.Rear seat-to-floor height (SHh)Available rear seat heights: SHh 400 to SHh 490 in 10 mm steps.To adjust the rear seat height it is necessary to change the rear suspension configuration of thespring (or fixed connection piece) and distance rings, Chap.
