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 levers or pedals become
inoperable if obstacle jams in operation stroke of the
travel levers/pedals, pilot control shut-off lever or control
levers, which may result in serious injury or death.
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 travel pedals during operation, resulting in serious
injury or death.

SAFETY

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 hand-holds.
Never jump on or off the machine. Never mount or
dismount a moving machine.
Before getting on or off the machine, check the condition
of the steps and handrails for sticking of slippery material
like grease or mud. Thoroughly remove such material if
stuck. In addition, repair the damage to the steps and/or
handrails. Retighten loose bolts.
Never get on and off the machine with tools in your
hands.
Adjust the Operator's Seat
A poorly adjusted seat for either the operator or for the
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 control levers with his back
against the seat back.
If not, move the seat forward or backward, and check
again.
Adjust the rear view 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.
