OPERATION
DECELERATOR/BRAKE PEDAL
When passing over the top of a hill or when dumping soil from a cliff, the load on the machine will
suddenly be reduced and the travel speed will increase. This situation is dangerous.
Depress the decelerator/brake pedal to lower the travel speed.
On a flat ground, you can stop the machine by using the decelerator/brake pedal. However, this
does not mean that brake is applied.
On a downhill, even if you depress the decelerator/brake pedal and lower the engine speed, ma-
chine may travel.
Be extremely careful of this on a downhill.
When driving down the slope, select the speed range at which engine brake is effective, and de-
press the decelerator/brake pedal as needed.
The decelerator/brake pedal is used to lower the engine speed
or lower the travel speed to stop the machine.
Depress this pedal to lower the travel speed before changing
the travel direction.
When you depress the decelerator/brake pedal, it stops at the
point where the depressing effort increases. If you depress it
further, the mechanical brake is applied.
