United States 81V145000
GRUMMAN FLXIBLE CORP.
The problem
THE SET-SCREW MAY NOT BE POSITIONED CORRECTLY, ALLOWING THE DRIVE KEY TO SLIDE OUT OF THE HUB AND THE HUB AND SPROCKET TO DISENGAGE. THIS WOULD CAUSE THE WHEELCHAIR PLATFORM TO FALL TO THE GROUND WITHOUT PRIOR WARNING.
What owners should do
WHEELCHAIR LIFT WILL BE INSPECTED FOR THE CORRECT POSITIONING OF THE SET-SCREW. IF NECESSARY, THE DRIVE KEY WILL BE TACK WELDED INTO THE DRIVE HEX WITHOUT CHARGE.
