（1）Thewheelchairframemustnothaveacamberangle.
（2）Thewheelchairframemustbesufficientlystrong.(Notethatthestrengthofawheelchairframemayde-
clinewithprolongeduse.)
Example:
 ・Playordeformationincomponentssuchasrivets,boltfasteningsorcasters.
 ・Componentswithvisiblewearorcorrosion.
2.1 StrengthRequirements
ToinstalltheE-Move,thewheelchairframemustmeetthestrengthrequirementslistedbelow.
Warning
・DonotinstalltheE-Moveonawheelchairframethatdoesnotmeetthestrengthrequirements.
2.2 StructuralRequirements
ToinstalltheE-Move,thewheelchairframemustmeetthestructuralrequirementslistedbelow.
Warning
・DonotinstalltheE-Moveonawheelchairframethatdoesnotmeetthestructuralrequirements.Even
whereitcanbesuccessfullyinstalled,problemsmayariseduringusethatcouldcauseinjuryorac-
cident.
2.2.1 Wheelchairframe
（1）Thediameteroftheaxleholeis18mmor20mm.
（2）Thecontactsurfacesforthenutsaroundtheaxleholemustbe󲥭atandhaveamplesurfacearea.
（3）WhentheE-Moveisinstalled,theremustbenointerference betweentheE-Moveand thewheel-
chairframe.
nImportant
・Ifyouareusingoffsetwasherstoavoidsuchinterference,checkthetwoitemsbelowandinstalluptothree
washersoneachside.
− Thenutseatsarecompletelysecure.

cident.
ToinstalltheE-Move,thewheelchairframemustmeetthefunctionalrequirementslistedbelow.
（1）Theframemustbeconstructedtoallow22-or24-inchwheelstobeattached.
（2）Thewheelchairisequippedwithaparkingbrakethatcanberelocatedandadjustedtothecor-
rectpositiononthetires.Whenapplied,thebrakemustbecapableofstoppingthewheelchair
withtheE-Moveinstalledona7°forwardorbackwardincline.
（3）WiththeE-Moveinstalled,itmustbepossibletotipthewheelchairforwardandbackbyatleast
20°andtothesidebyatleast15°.

Warning
・When cutting cable ties, do not cut on an angle. Always cut off the
surplus as close as possible to the fastener. Cable ties cut to a
pointcouldcauseinjurytothecustomer.
Note
・In locations where the tightening torque is specified, always tighten to the specified torque.
Insufficient tightening torque will cause looseness, while excessive torque could cause dam-
age.
