3.
Tyres are in good condition and correctly inflated - see specification table. Or as specified on the
Tyre Side Walls.

Check the operation of all controls and that they function correctly.
Operation
The Control Box can be fitted to either the right or left hand standard Armrest or as an option a detachable
Adjustable Armrest is available to give further adjustments of the Armrest and Controller. Contact your
INVACARE supplier/dealer. The Joystick mounted on top of the Control Box and the movement of the
Joystick determines the direction that the chair will travel (i.e. forward movement of the Powerchair is
achieved by pushing the Joystick forward and likewise for movement to the left, right and backward
directions). When the Joystick is released, it automatically returns to a neutral position, triggering the
automatic brake function and bringing the Powerchair to a immediate stop. Consult the Controller User
Guide, provided for further information or Contact INVACARE supplier/dealer or your prescriber.
The speed of the Powerchair is controlled via a Rotary Switch located at the back of the Control Box.
Drive Mechanism
The Powerchair is fitted with two 24V motors that drive the rear wheels.
The drive mechanism couplings can be disconnected by grasping the lip (1) at
the centre of the rear wheels, pulling outwards and twisting through 90°. The
Powerchair will then freewheel and is able to be pushed by an attendant.
Freewheel Operation
To push the Powerchair by hand in the event of a fault or battery failure, or simply to
move it WITH NO OCCUPANT in it, the two motor/gearbox units can be declutched
from the rear wheels. First ensure that power is switched OFF on the joystick box.
Then, repeat the procedure described in the Drive Mechanism paragraph, above. To
restore powered drive, turn BOTH lips back to their normal position.
CAUTION
Freewheel operation is only intended for short-term use in SPECIAL CIRCUMSTANCES, NOT as a regular or
permanent mode of Powerchair movement. In freewheel mode the Powerchair is NOT secured by the
electromagnetic brakes, as both brake systems are out of action during this time. Before you attempt to drive the
Powerchair again, ensure that both drive couplings are fully engaged.
Driving Practice
Release the manual wheel locks. With the joystick you now control movement and direction of the
Powerchair. To reverse, pull the joystick backward. By moving the joystick left or right (while the
Powerchair is moving forward or backward) you steer the Powerchair. Push the joystick full left or right,
and the Powerchair will turn around within its smallest turning circle. To slow down, guide the joystick
towards its centre (neutral) position. If you have to stop in an emergency, simply release the joystick. It will
automatically snap back to neutral and the Powerchair will come to a smooth halt. As a last resort ONLY
press the On/Off switch which will serve as an emergency off switch. Once at a standstill, the Powerchair is
instantly locked by the electromagnetic parking brakes, so that it is perfectly safe while it is stationary, even
on an incline.
Transferring to and from your Powerchair
Circumstances and individual needs will vary from person to person, we advise you consult your Therapeutic
Adviser who will help to advise and develop your skills for the appropriate transfer methods to suit your
individual requirements. DO NOT attempt transferring unaided until you are confident and proficient in the
skills to do so, remember always during transfer make sure the brakes are in the locked position and the
Powerchair is manouvered as close as possible to the transfer seat and switched off.
