Operation

Checks before operation
When carrying out the checks, move the machine to a wide area
where there are no obstructions, and operate slowly. Do not
allow anyone near the machine.
Always fasten your seat belt.
Check the operation of travel, steering and brake systems,
and work equipment control system.
Check for any abnormality in the sound of the machine,
vibration, heat, smell, or gauges; check also that there is no
leakage of oil or fuel.
If any abnormality is found, carry out repairs immediately.
Before driving the machine or starting operations, check that
safety bar (1) is securely fixed at the FREE position.
Precautions when traveling in forward or reverse
Before travelling, check again that there is no one in the sur-
rounding area, and that there are no obstacles.
Before travelling, sound the horn to warn people in the area.
Always operate the machine only when seated.
Do not allow anyone apart from the operator to ride on the
machine.
Check that the back-up alarm (alarm buzzer when machine
travels in reverse) works properly.
Always lock the door and windows of the operator's compart-
ment in position (open or closed).
On jobsites where there is a hazard of flying objects or of
objects entering the operator's compartment, check that the
door and windows are securely closed.
If there is an area to the rear of the machine which cannot be
seen, position a signal person. Take special care not to hit
other machines or people when turning or swinging the
machine.
Always be sure to carry out the above precautions even
when the machine is equipped with mirrors.
