CONTROLLER AND CHARGER
Servicing of the controller and charger should only be carried out by your local approved dealer.
Do not attempt to open the units. Broken seals will invalidate the warranty.
BRAKES
WE STRONGLY RECOMMEND EVERY 6 MONTHS TO CHECK THE FUNCTION OF THE ELECTRONIC BRAKES AND WHEEL - LOCKS ADJUSTMENT. ( THIS SERVICE MAY NOT BE FREE OF CHARGE ).
MOTORS
The motors are fitted with long life brushes. These should be inspected for wear at twelve months or more frequently if you use the chair daily for long periods. The brushes should be replaced when they have worn down to 8mm in length.
DO NOT OVERLOAD THE MOTORS IN PROLONGED STALL CONDITIONS. If the chair is used continuously for long periods, pause periodically to allow the motors to ‘cool down’.
DRIVE WHEELS
The
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 authorised INVACARE dealer.
