4.3.3 Electronic Joystick Calibration
(without TLC)
Locate the forklift in an area where the boom can
be safely operated in all positions, out-of-doors
and clear of power lines. A small screwdriver with
a 3 inch long shank and a 1/8 inch wide blade will
be required.
Carefully remove the four plastic caps located on
the left side of the right console below the elec-
tronic joystick, Fig. 4.8. These holes provide
access to the driver modules calibration adjust-
ments.
IMPORTANT: The driver module adjustment
screws turn very easily and less than one full turn.
DO NOT use excessive force when turning these
screws, as they can be damaged very easily!
With the forklift engine shut off, try locating the
four adjustment screws; a flashlight aimed through
the holes will help in locating the screw slots. Very
carefully turn each adjustment screw clockwise
and then counterclockwise, observing the left and
right stop positions of each adjustment screw. DO
NOT force the screws past their left and right stop
positions. If any of the stops are non existent the
driver module will not function properly and must
be replaced.
While the machine is shut off, observe the follow-
ing functions of the joystick. When you move the
joystick forward (boom lower) or to the right (boom
extend) listen very carefully and you will hear two
switch “clicks”. You are now familiar with the
components used to calibrate the electronic
joystick. A second person will make the job
easier.
NOTE: You will hear only one switch “click” when
the joystick is moved into the boom raise and
boom retract positions. These joystick positions
are not used during calibration.
To calibrate the Raise/Lower functions, proceed
as follows:
