OPERATION
BUCKET CONTROL LEVER
This lever (4) operates the bucket.
Position (a): TILT
When the bucket control lever is pulled further
from the TILT position, the lever is stopped in this
position until the bucket reaches the preset posi-
tion of the positioner, and the lever is returned to
the HOLD position.
Position (b): HOLD
The bucket is kept in the same position.
Position (c): DUMP
BRAKE PEDAL
q When traveling downhill, always use the right brake pedal, and use the braking force of the engine
together with the brake.
q Do not use the brake pedal excessively. If the brake is used too frequently, the brake will overheat. If
this happens, the brakes will not work and may lead to a serious accident.
q Do not put your foot on the brake pedal unless necessary.
These pedals (5) operate the brakes.
Use the brake pedal for normal braking operations.
The left and right pedals are interconnected and work together.
REMARK
When using the brake pedal and accelerator pedal together to
reduce the travel speed or stop the machine when carrying out
the operation, it is more convenient to use the left brake pedal.
