4.8.6.a

CHECKING THE HYDRAULIC OIL LEVEL

The oil level must be checked with cold oil and the machine
q
positioned on level ground and in lubricating position.
If it is necessary to top up, stop the engine and eliminate
q
the residual pressure from the equipment circuits (by
moving the controls more than once) and from the tank (by
slowly loosening the filler cap (2)).
The oil level must be visible through the window (1) provided on
the tank and must be included between the MIN. and MAX.
marks.
If the level is near the MIN. reference mark, open the engine hood
(see "3.5.1 ENGINE HOOD") and top up through the filler (2)
using the prescribed type of hydraulic oil (see "4.3 FUEL,
COOLANT AND LUBRICANTS"). Put back the filler cap (2) and
close the engine hood.
IMPORTANTE
Do not exceed the MAX. reference mark. This would
q
damage the hydraulic circuit and cause the oil to overflow.
If you notice a constant, unusual decrease in the oil level,
q
contact your Komatsu Dealer.
