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.
Note: The joystick must be calibrated before the
threshold, max-out or ramping can be set.
Note: Perform this procedure with the engine off.
1 Open the platform control box.
2 Pull out the red Emergency Stop button to the
on position at both the ground and platform
controls.
3 Turn the key switch to platform control. Do not
start the engine.
4 Select a joystick to calibrate.
5 Disconnect the wire harness connector from the
joystick for approximately 10 seconds or until
the alarm sounds. Connect the wire harness
connector to the joystick.
6 Move the joystick full stroke in either direction
and hold for 5 seconds.
7 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.
Result: The alarm should sound indicating
successful joystick calibration.
Result: The alarm does not sound. Check the
electrical connections or replace the joystick.
8 Repeat this procedure for each joystick
controlled machine function including the thumb
rocker steer switch.
Note: No machine fuction should operate while
performing the joystick calibration procedure.
How to Adjust the Joystick
Max-out Setting
The max-out setting of a joystick controls the
maximum speed of a joystick-controlled machine
function. Whenever a hydraulic cylinder, drive
motor or hydraulic pump is replaced, the max-out
setting should be adjusted to maintain optimum
performance. The max-out settings on the joystick
can be changed to compensate for hydraulic pump
wear to maintain peak performance from the
machine.
Note: Perform this procedure with the boom in the
stowed position.
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 Push in the platform controls red Emergency
Stop button to the off position.
4 Do not press down the foot switch.
5 Move and hold the drive enable toggle switch in
the right position and pull out the red
Emergency Stop button to the on position.
6 When the alarm sounds, release the drive
enable toggle switch.
