MAINTENANCE
7-102
Check Accelerator Pedal Operation, and Exhaust Gas
Color and Noise
--- every 10 hours (daily)
WARNING: Move the forward/reverse lever to neutral.
Apply the parking brake. After resting the bucket level
to the ground, block the wheels.
While slowly stepping on accelerator pedal (1), check that the
engine speed smoothly increases. Then, while slowly returning
accelerator pedal (1), check that the engine speed smoothly
decreases.
Exhaust Gas Color and Noise:
DANGER: Exhaust inhalation hazard. Ventilate the
shop with fresh air when carrying out warming up
warm-up operation indoor. Failure to do so may cause
asphyxiation from exhaust gas, resulting in death or
severe injury.
Exhaust gas color is normally transparent or light
blue. Although exhaust gas color is a light white color
immediately after the engine is started or quickly
accelerated, this symptom is not abnormal. If the exhaust
gas color turns black, white, brown, or gray, check the
engine oil level and the fuel supply system for problems.
In addition, check that no abnormal noise is heard coming
from the engine or muffler.
