REVERSING AWAY FROM DUMP TRUCK
NOTICE
q
Do not shift down with the accelerator pedal depressed (with the engine speed raised). If the transmis-
sion is shifted down when the engine speed is high, there will be an excessive load on the engine,
torque converter, transmission, axles, final drive, and the whole power train. In addition, the tires will
slip and this will cause wear of the tires.
q
Do not operate the steering immediately after switching between forward and reverse (when the
machine is stationary). If the steering is operated when the machine is stationary, it will cause wear or
cuts to the tires.
1. Switch to R2 and drive in reverse.
2. While driving in reverse, lower the lift arm and operate the
steering to face the position for scooping up.
3. Depress the brake pedal and stop the machine.
4. Let back the accelerator pedal to reduce the engine speed,
then switch from R2 to F2.
5. Lower the bucket to the ground and drive forward to clear
the surface (remove all boulders).
Do not operate the steering when carrying out the leveling
operation. Travel forward with the machine facing directly
to the front.
