GENERAL
Avoid knocking your integral controller, especially the joystick. When transporting your wheelchair,
ensure that the controller is well protected, especially the cables. To prolong the controller’s life, keep
exposure to extreme conditions to a minimum. Do not expose the controller to damp conditions
for prolonged periods. Always clean your controller if it becomes contaminated with food or drink.
Use a damp cloth and dish soap mixed with water. Be careful when cleaning the joystick. Do not use
abrasive or solvent based cleaning agents.
Perform the following daily and weekly control system checks as directed. If the control system fails
any of these checks, do not use the wheelchair; contact your Graham-Field dealer.
