4. Check the operation of the lift and lower functions. Push
the lift button and then the lower button. Check that the
forks raise and lower. If the lift truck is equipped with a aux-
iliary control panel, check operation of the lift and lower
functions on the panel.
5. Check the operation of the traction reverse function.
Slowly rotate the speed/direction control for slow travel in
the control handle direction. Push the traction reverse but-
ton without changing the position of the speed/direction
control. The lift truck must stop and then accelerate in the
opposite direction. Once the lift truck changes direction and
moves with the control handle trailing, release the traction
reverse button without releasing the speed/direction con-
trol. The lift truck should not accelerate in the control han-
dle direction. (Once the traction reverse button has been
pressed, the traction motor should not accelerate the lift
truck toward the control handle). Full direction control may
be re-established by rotating the speed/direction control to
the OFF position or by moving the control handle to a brake
ON position.
6. Check the steering function. Move the control handle to
the right and left. Check for smooth movement of the steer
(drive) wheel in the same direction. Steering will be more
difficult if the lift truck is stopped.
7. Check the operation of the optional creep speed but-
ton. Move the control handle to the vertical position. Press
and hold the Creep Speed button while rotating the direc-
tion/speed control. The truck should operate at only
1.6 km/h (1 mph). Lowering the control handle will maintain
the Creep Speed until the button is released. To reactivate
the Creep Speed, the control handle must be returned to
the vertical position.
Wheels and Tires
Check the drive tire and load wheels for foreign material,
cuts, and tears. Remove all foreign material and smooth
any cuts or tears to prevent further damage. See Fig-
ure 19.
