Lift truck Maintenance 8-19
Section 8. Planned Maintenance
Transistorized Traction Control
Test for correct function of the traction control. Check creep speed,
high speed, and plugging.
CAUTION
!
Check and make sure the travel area is clear before each
movement and before each change of direction.
1. Check creep speed and high speed while driving the truck in a
straight line in both forward and reverse directions. All speed
changes should be smooth while increasing and decreasing
speed. Notice any unusual drivetrain noise or action of the con-
trols and drive train components.
Stop the truck with the service brakes. Note any unusual reac-
tions in driving or braking performance. Note any need for
adjustment.
2. Check the plugging function first at a slow speed. If operating
correctly, then test at full speed.
First, drive the truck in the FORWARD direction. Push the accel-
erator pedal and allow the truck to accelerate to the desired
travel speed. Then, move the direction control to the REVERSE
position while your foot is still depressing the accelerator pedal.
The truck should slow to a smooth, controlled stop and acceler-
ate in the opposite direction.
Repeat the test by moving the direction control back to the for-
ward position.
Check the accelerator control while conducting the speed range
tests. It must move easily and smoothly throughout the acceleration
stroke and return without binding.
Test the service brake (drive motor cut-off) switch.
Drive the truck in FORWARD (or in REVERSE) at creep speed.
While holding the accelerator pedal steady, push on the brake pedal
with your left foot. The braking action should interrupt power to the
drive motor and stop the truck. Release the brake pedal. The drive
motor should start moving the truck again.
IMPORTANT
When you have completed the operational tests, park and
leave the truck according to standard shut down proce-
dures.
Be sure to make a record of all maintenance and opera-
ting problems you find.
