SAFETY EQUIPMENT
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 incorrect operation. Do not use
water or steam to wash the electrical system (sensors, con-
nectors).
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.
KEEP OPERATOR'S COMPARTMENT CLEAN
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.
LEAVING OPERATOR'S SEAT WITH LOCK
q
Before standing up from the operator's seat (such as when
opening or closing the front window or roof window, or when
removing or installing the bottom window, or when adjusting
the operator's seat), always lower the work equipment com-
pletely to the ground, set lock lever (1) securely to the LOCK
position (L), then stop the engine. If you accidentally touch
the control levers or control pedals 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 lock lever (1) securely to
the LOCK position (L), 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.
