BUCKET DUMP OPERATION WHEN DIGGING
Do not operate the bucket in the DUMP direction when digging. If the bucket control lever is operated to the DUMP
position during digging, the machine will not be able to travel forward, the tires will slip, and an excessive load will
be brought to bear on the work equipment.
Carry out the scooping-up operations as follows.
1. When thrusting the bucket in, raise the lift arm slightly at
the same time. Ample driving force will work on the front
wheels.
2. To fill the bucket, operate the bucket tilt and lift 2 - 3 times
repeatedly when thrusting the bucket in.
Operate the control lever slowly near the end of the bucket
tilt.
3. When the bucket reaches the end of the tilt stroke, depress
the brake pedal to stop the machine.
When doing this, do not push the bottom of the bucket
against the dilution. If the bucket is pushed against the dilu-
tion, the bucket, cylinders, and work equipment will be
damaged.
4. When the scooping-up operation is completed, operate the bucket tilt and dump, and apply the brakes when
traveling in reverse to stabilize the load inside the bucket and prevent spillage of the load.
REMARK
To reduce the generation of heat by the torque converter, keep the target time for the digging operation within 10
seconds from the start of thrusting in to the completion of scooping up.
The fuel consumption increases while digging working. Fuel cost is saved by shortening the digging time.
FRONT WHEELS GOING ON BLASTED ROCK
Do not carry out operations that make the front wheels ride up
on blasted rock. If the front wheels go on top of blasted rock,
there is danger that the sharp parts of the blasted rock will cut
the tires.
In particular, avoid pushing the bucket in too far, and when
operating near natural rock after blasting (roots), do not let the
front wheels ride up on the natural rock (roots). For scooping-
up operations near natural rock (roots), do not use a wheel
loader. Use a bulldozer or hydraulic excavator.
