GUIDES TO MAINTENANCE
Do not allow water to get on the monitors and controllers
G
inside the operator's cab.
Never spray steam or water directly at the radiator or oil
G
cooler portions.
Pre-and post-work checks:
Before starting work in mud, rain, snow or at seashore, check
plugs and valves for tightness. Wash the machine immediately
after the work to protect components from rusting. Lubricate com-
ponents more frequently than usual.
Be sure to lubricate work equipment pins daily if they are sub-
merged in water.
Dusty worksites:
When working at dusty worksites, do as follows:
Inspect the air cleaner clogging monitor to see whether the air
G
cleaner is blocked. Clean the air cleaner at shorter intervals
than specified.
Clean the radiator core frequently to avoid clogging.
G
Clean and replace the fuel filter frequently.
G
Clean electrical components, especially the starting motor
G
and alternator, to avoid accumulation of dust.
Avoid mixing oils:
Never mix oils of different brands. If you have only oil which is a
different brand from the one that is used in the machine, do not
add it but replace all the oil.
