3.2 Explanation of components
7. Brake pedal
WARNING
When traveling downhill, always use the right brake pedal,
and use the braking force of the engine together with the
brake.
Do not use the brake pedal excessively. If the brake is used
too frequently, the brake will overheat. If this happens, the
brakes will not work and may lead to a serious accident.
Do not put your foot on the brake pedal unless necessary.
These pedals (7) 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.
8. Accelerator pedal
This pedal (8) controls the engine speed and output.
The engine speed can be freely controlled between low idling
and full speed.
