250, 500 and 1000 hours of operation also fall into this mainte-
nance category.
HYDRAULIC SYSTEM, OIL CHANGE
• Frequent skin contact with used hydraulic oil may cause
skin damages and other injuries!
Use rubber gloves for exchanging the filter. Wash any
spilled hydraulic oil thoroughly from your skin.
• Danger of being burnt! The hydraulics tank is under pres-
sure. Hot hydraulic oil may squirt out and cause injuries!
Use rubber gloves and hold the oil trough under the dis-
charge hole in such a way that you cannot come into con-
tact with the extruding oil.
Keep a collecting container with sufficient capacity ready.
1. Park the machine on level ground.
2. Lower the work unit onto the ground.
3. Switch off the engine.
4. Secure the articulated steering with the articulated steering
lock (1).
5. Unlock the feeding and ventilation screw (2) by turning it
slowly to let the pressure escape.
6. Loosen the screw plug (4) of the hydraulic oil tank and let
theoilrunoff.
7. Re-tighten the screw plug with its seal being in perfect con-
dition.
8. Unscrew the feeding and ventilation screw.
9. Fill up oil until the oil level is between the center and top
edge of the inspection glass (3).
10. Start up the engine.
11. Raise and lower the work equipment several times, while op-
erating the bucket at the same time.
12. Lower the bucket onto the ground and bring it into mining
position.
13. Check the oil level with the engine running idle in its low
speed position.
14. Ventilate the hydraulic oil tank (see section "Bleeding the
Hydraulic Oil Tank").

• Do not fill up with too much hydraulic oil! Otherwise, the
pressure in the hydraulic oil container increases to very
dangerous levels.
