Do not check, maintain or remove the
pre-cleaner during operation.
* Otherwise, dust or other foreign particles may
enter the engine and accelerate wear of the
parts, which causes damage to the devices
including the turbocharger.
Take care that parts will not fall down
and get caught in the fuel control link.
* If parts are caught in the fuel control rack, the
engine will become out of control.
Make sure that the pre-cleaner is free
from clogging.
* Insufficient intake air may result in loss of
power, incomplete combustion, exhaust gas
temperature rise, and overspeed of the
turbocharger.
