SAFETY

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 that the movement of the machine matches the display on the control pattern card. If it does not match,
replace it immediately with the correct control pattern card.
Check the operation of the work equipment, traval system and swing 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.

Safety Rules for Changing Machine Directions

Before traveling, position the upper structure so that the
sprocket is at the rear of the operator's cab. If the sprocket is at
the front of the operator's cab, the machine makes a movement
reverse to the control lever movement (for example, forward
becomes reverse, and left becomes right). Be careful to avoid
such a reverse movement of the machine.
Before travelling, check again that there is no one in the
surrounding 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 travel alarm works properly.
Always lock the door and windows of the operator's
compartment 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.
