Checking The Oil Level In The Hydraulic Circuit - Komatsu PC12R-8 Operation & Maintenance Manual

4.7.3.e CHECKING THE OIL LEVEL IN THE HY-
DRAULIC CIRCUIT
DANGER
• The oil level in the hydraulic circuit must be checked with
cold oil and the machine positioned on level ground, with
retracted bucket and arm cylinders and the bucket teeth
resting on the ground; the oil level must be visible
through the gauge (1) positioned on the tank and must be
included between the MIN. and MAX. marks.
To top up, use the suitable hydraulic oil.
(See "4.3 FUEL, COOLANT AND LUBRICANTS").
• If a constant or abnormal decrease of the oil level is ob-
served, thoroughly check the hydraulic circuit, the pis-
tons and the pump for leaks.
IMPORTANT
• When topping up, do not exceed the MAX. level. This
would damage the hydraulic circuit and cause the oil to
flow out.
