BRAKE PEDAL
WARNING
q
When traveling downhill, always use the right brake pedal, and use the braking force of the engine
together with the brake.
q
Do not use the brake pedal repeatedly more than necessary. If the brake is used too frequently, the
brake will overheat. If this happens, the brakes will not work, so this may lead to a serious accident.
q
Do not put your foot on this pedal unless necessary.
These pedals (6) operate the brakes.
RIGHT BRAKE PEDAL
The right brake pedal operates the wheel brakes.
Use the right brake pedal for normal braking operations.
LEFT BRAKE PEDAL
The left brake pedal operates the wheel brakes.
When the transmission cut-off switch is in the ON position, and if this brake pedal is depressed, wheel brakes are
applied and the transmission is set to the neutral position at the same time. If the transmission cut-off switch is at
OFF, the left brake pedal acts in the same way as the right brake pedal.
REMARK
When the accelerator is being used for operating the work equipment, always set the transmission cut-off switch to
the ON position and use the left brake pedal to slow or stop the machine.
ACCELERATOR PEDAL
This pedal (7) controls the engine speed and output.
The engine speed can be freely controlled between low idle
and full speed.
