SAFETY

SAFETY FEATURES

q Be sure that all guards and covers are in their proper position. Have guards and covers repaired immediately if
they are damaged.
q Understand the method of use of safety features and use them properly.
q Never remove any safety features. Always keep them in good operating condition.

KEEP MACHINE CLEAN

q If water gets into the electrical system, there is a hazard
that it will cause malfunctions or misoperation. Do not use
water or steam to wash the electrical system (sensors,
connectors).
q If inspection and maintenance is carried out when the
machine is still dirty with mud or oil, there is a hazard that
you will slip and fall, or that dirt or mud will get into your
eyes. Always keep the machine clean.
INSIDE OPERATOR'S COMPARTMENT
q When entering the operator's compartment, always remove all mud and oil from the soles of your shoes.
If you operate the pedal with mud or oil affixed to your shoes, your foot may slip and this may cause a serious
accident.
q Do not leave parts or tools lying around the operator's compartment.
q Do not stick suction pads to the window glass. Suction pads act as a lens and may cause fire.
q Do not use cellular telephones inside the operator's compartment when driving or operating the machine.
q Never bring any dangerous objects such as flammable or explosive items into the operator's compartment.

ALWAYS APPLY LOCK WHEN LEAVING OPERATOR'S SEAT

q Before standing up from the operator's seat (such as when
adjusting the operator's seat), lower the work equipment
completely to the ground, set safety lock lever (1) and
parking lever (2) securely to the LOCK position, then stop
the engine.
If you accidentally touch the levers when they are not
locked, there is a hazard that the machine may suddenly
move and cause serious injury or property damage.
q When leaving the machine, always lower the work equip-
ment completely to the ground, set safety lock lever (1) and
parking lever (2) securely to the LOCK position, then stop
the engine. Use the key to lock all the equipment. Always
remove the key, take it with you, and keep it in the specified
place.
