General Precautions for Cab
•Before entering the cab, thoroughly remove all dirt and/or
oil such as mud, grease, soil or stones that may mess up the
cab from the soles of your work boots. If any controls such
as a pedal is operated while with dirt and/or oil on the soles
of the operator’s work boots, the operator’s foot may slip off
the pedal, possibly resulting in a personal accident.
• Do not mess up around the operator’s seat with parts,
tools, soil, stones, obstacles that may fold up or turn
over, cans or lunch box. The pedals become inoperable if
obstacle jams in operation stroke of the accelerator pedal,
electric brake pedal or service brake pedal, which may
result in serious injury or death.
• Do not leave parts and/or tools lying around the
operator’s seat. Store them in their specified locations.
• Avoid storing transparent bottles in the cab. Do not
attach any transparent type window decorations on
the windowpanes as they may focus sunlight, possibly
starting a fire.
• Refrain from listening to the radio, or using music
headphones or mobile telephones in the cab while
operating the machine.
• Keep all flammable objects and/or explosives away from
the machine.
• After using the ashtray, always cover it to extinguish the
match and/or tobacco.
• Do not leave cigarette lighters in the cab. When the
temperature in the cab increases, the lighter may
explode.
• Use proper floor mat dedicated to the machine. If another
floor mat is used, it may be displaced and contact with
the accelerator pedal, electric brake pedal or service
brake pedal during operation, resulting in serious injury
or death.
•When operator drives the machine with decreased
attentiveness, resulting in serious injury or death.
• Never operate the machine in the state with drinking
alcohol or drug.
Use Handholds and Steps
•Falling is one of the major causes of personal injury.
• When you get on and off the machine, always face the
machine and maintain a three-point contact with the
steps and handrails.
• Do not use any controls as handholds.
• Never jump on or off the machine. Never mount or
dismount a moving machine.
• Be careful of slippery conditions on platforms, steps, and
handrails when leaving the machine.
• Do not step or climb on surfaces, which are not intended
for walking. Step only on the areas provided with the slip
resistant surfaces.

work at hand may quickly fatigue the operator leading to
misoperations.
• The seat should be adjusted whenever changing the
operator for the machine.
• The operator should be able to fully depress the pedals
and to correctly operate the steering wheel with his back
against the seat back.
• If not, move the seat forward or backward, and check
again.
• Adjust the mirror position so that the best rear visibility is
obtained from the operator’s seat. If the mirror is broken,
immediately replace it with a new one.
Fasten Your Seat Belt
•If the machine should overturn, the operator may become
injured and/or thrown from the cab. Additionally the
operator may be crushed by the overturning machine,
resulting in serious injury or death.
• Prior to operating the machine, thoroughly examine
webbing, buckle and attaching hardware. If any item is
damaged or worn, replace the seat belt or component
before operating the machine.
• Be sure to remain seated with the seat belt securely
fastened at all times when the machine is in operation to
minimize the chance of injury from an accident.
• We recommend that the seat belts are replaced every
three years regardless of its apparent condition.

problems. If there are problems, replace the problem
parts or clean the mirrors, cameras and monitors.
