WARNING
z
If inspection, cleaning, or maintenance is carried out with the
engine running, dirt will get into the engine and damage it.
Always stop the engine before carrying out these operations.
z When using compressed air, there is danger that dirt may be
blown around and cause serious injury.
Always use safety glasses, dust mask, and other protective
equipment.
Checking
If air cleaner clogging caution lamp (1) on the machine monitor
lights up, clean the air cleaner element.
NOTE
Do not clean the element until the air cleaner clogging caution
lamp lights up.
If the element is cleaned frequently before the air cleaner clog-
ging caution lamp lights up, the air cleaner will not be able to dis-
play its performance fully and the cleaning efficiency will drop.
In addition, the frequency of dirt stuck to the element falling
inside the inner element will increase.
A dust indicator is installed inside the engine hood on the left
side of the machine. The dust indicator shows the condition of
clogging of the air cleaner in 5 stages. This makes it possible to
check how clean the element is and when it should be replaced.
