Warning: Before maintenance or repairs beneath the machine, lower all working devices onto the
ground or lowest position.
If the maintenance requires the running of engine, assign two operators for teamwork and keep
contact with each other.
One operator must sit in the driver seat to get ready to stop the engine immediately when
necessary. This operator must pay special attention not to touch any joystick or pedal, unless it’s
absolutely necessary.
The other operator for the maintenance must keep the body and clothing away from motion
parts of machine.
