3.3 Operation
Try to keep the load in the center of the bucket; if the load is
on one side of the bucket, the load will be unbalanced.
Stock pile
Blasted rock
4. At the same time as thrusting the bucket into the material,
raise the lift arm to prevent the bucket from going in too far.
By raising the lift arm, ample traction will be produced by the
front tires.
REMARK
If the bucket is thrust too much and the lift arm stops rising or the
machine stops moving forward, release the accelerator pedal a
little. Proper operation of the accelerator pedal for each type of
the soil is effective for saving of fuel and prevention of wear of
the tires.
5. Check that there is enough material loaded into the bucket,
then operate the bucket control lever to tilt the bucket and
load the bucket fully.
REMARK
If the bucket edge is moved up and down while pushing in the
bucket and digging, the front tires will come off the ground and
this will cause the tires to slip.
