Fault Finding

Remember that most power drive problems are battery related. Sometimes expensive components are
unnecessarily replaced when in fact the problem was batteries. If an electrical problem exists, always check
the batteries first, also check cable connections for good contact. The electronics involved in the controller
and lift and recline modules are quite sophisticated:- electronic repairs should be carried out by trained
personnel.
IF YOUR CHAIR WILL NOT START:
• Check that the control box is switched 'on', the display will be illuminated and remain stationary.
• Check that both motors are engaged.
• Check that the main controller cable is firmly pushed 'home'.
• Do not move the joystick until the display is illuminated.
IF THE WHEELCHAIR PULLS TO ONE SIDE:
• Check that the motors are fully engaged.
• Check that pneumatic tyres are inflated to correct pressure.
• Check that the castors move freely, and there is no free play at castor stem.
• Check joystick drive function is in line with the left and right response. One motor may be unplugged.

If your chair still has a problem after making these checks, please contact your INVACARE dealer
