How to Calibrate a Joystick
The joystick controllers on this machine utilize
digital Hall Effect technology for proportional
control. If a joystick controller 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 and return the joystick to the neutral
position.
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 function should operate while
performing the joystick calibration procedure.
How to Adj ust the Joystick Max- out Setting 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 controls. Do
not start the engine.
3 Push in the platform 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.
7 Momentarily activate the drive enable toggle
switch in the right direction 4 times.
Result: There should be a pause and the
alarm should sound 4 times indicating that the
machine is in max-out calibration mode.
Result: The alarm does not sound. Repeat
steps 3 through 7.
