How to Calibrate a Joystick
The joysticks on this machine utilize digital Hall
Effect technology for proportional control. If a
joystick is disconnected or replaced, it must be
calibrated before that particular machine function
will operate.
The joystick must be calibrated
before the threshold, max-out or
ramping can be set.
Perform this procedure with the
engine off.
1 Pull out the red Emergency Stop button to the
on position at both the ground and platform
controls.
2 Turn the key switch to platform control. Do not
start the engine.
3 Select a joystick to calibrate.
4 Move the joystick full stroke in either direction
and hold for 5 seconds.
5 Return the joystick to the neutral position,
pause for a moment, then move the joystick full
stroke in the opposite direction. Hold for 5
seconds and return the joystick to the neutral
position.
Result: The alarm should sound indicating
successful joystick calibration.
6 Repeat this procedure for each joystick
controlled machine function including the thumb
rocker steer switch.
No machine fuction should
operate while performing the
joystick calibration procedure.
4 Attach a grounded wrist strap to the ground
screw inside the platform control box.
