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 per-
sonal injury.
NOTE
z
Do not shift down with the accelerator pedal depressed (with
the engine speed raised). If the transmission 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.
z Do not operate the steering immediately after switching
between forward and reverse (when the machine is station-
ary). If the steering is operated when the machine is station-
ary, it will cause wear or cuts to the tires.
z If there is transmission cut off, do not turn the transmission
cut-off switch to the OFF position and depress the brakes or
raise the bucket. If the brakes are actuated in this condition,
heat will be generated in the brake chamber and this will
cause heat fatigue of the 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 acceler-
ator pedal to drive forward -> approach dump truck. If these
operations are carried out at the same time, the engine acceler-
ation will be poor and this will result in poor fuel consumption.
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 dilution.
