FUNCTIONING
Check the oil level in the hydraulic tank and top up
q Carry out this check when the oil is cold, with the machine positioned on level ground, bucket and arm
cylinders retracted and bucket teeth resting on the ground.
q Before topping up, stop the engine and eliminate the residual pressure from the equipment circuits
(by shifting the controls more than once) and from the tank by slowly loosening the filling cap.
1. If the work equipment is not in the conditions shown in the
diagram on the right, start the engine and run it at high
idling speed, retract the arm and bucket cylinders
completely and lower the boom until the bucket teeth touch
the ground. Stop the engine.
2. Open the engine hood and the radiator cover. For details,
see paragraph "RADIATOR COVER (3-33)"
3. Make sure that the oil level is included between the H and
L marks on the sight gauge (G).
NOTICE
q Do not exceed the max. level mark (H). This would
damage the hydraulic circuit and cause the oil to
overflow.
q If too much oil is added and this exceeds the level (H)
on the gauge, turn the turret so that the drain plug (P)
is positioned between the tracks, stop the engine, wait
for the hydraulic oil to cool down and drain the excess
oil through the drain plug (P).
4. If the oil level is below the L mark, remove the filler cap (F)
and top up using the oil recommended in the lubricant
chart (see "FUEL, COOLANT AND LUBRICANTS (4-12)").
REMARK
The oil level varies according to its temperature. Then keep to
the following instructions:
q Before operation: near level (L)
(Oil temperature ranging from 10°C to 30°C)
q Normal operation: near level (H)
(Oil temperature ranging from 50°C to 80°C)
