Keep clear of fan and fan belts when the engine is running. Rotating fan
and belt contact can cause injury.
Replace badly worn, greasy or cracked belts immediately.
These conditions
prevent proper belt function.
Visually inspect the drive belt for intersecting cracks. Transverse (across the belt
width) cracks are acceptable. Longitudinal

intersect with transverse
cracks are not acceptable.
Replace the belt if it is
frayed or has pieces of material missing.

of the pedal decreases engine speed for smoother changes in machine direction
and to ease the machine up to a load. Release the pedal to accelerate to the
engine speed control lever setting.
This pedal stops the machine when fully depressed. It also serves as a parking
brake when the brake pedal lock is applied.
Periodic adjustment
of the pedal might be required,
refer to your Komatsu
distributor if pedal values are not within those shown.

REVERSIBLE
FAN BLADES
A
WARNING
Keep clear of fan and fan belts when the engine is running. Rotating fan
and belt contact will result in serious injury.
The fan blades must be reversed to prevent corrosion and dirt build up that may
cause binding of the shafts in the fan hub. After reversing the blades return the
blades to the desired position.
