APPROACHING DUMP TRUCK
WARNING
Do not operate the steering suddenly when the bucket is raised. If the steering is operated when the
bucket is raised, there is danger that the machine may tip over and cause serious personal injury.
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.
q
If a transmission cut-off system is installed, turn the transmission cut-off switch to the OFF position
and depress the brake, but do not raise the bucket. In this condition, the brake is operated, so heat is
generated in the brake chamber and this will cause heat fatigue to parts inside the axle.
1. Let the accelerator pedal back to reduce the engine speed,
then depress the parking brake pedal to stop the machine.
2. Shift gear from R2 to F2.
3. Operate the steering to set the load that at right angles to
the dump truck, then drive forward.
REMARK
Operate the steering in the following order: let accelerator
pedal back
→
switch between forward and reverse
→
depress
accelerator pedal to drive forward
→
approach dump truck. If
these operations are carried out at the same time, the engine
acceleration will be poor and this will result in poor fuel con-
sumption.
4. Raise the bucket to adjust the bucket height so that when
the bucket is tilted down, the cutting edge of the bucket
does not hit the bottom face of the dump body or the dilu-
tion.
