4.9.3 PTO’s (PUMP DISTRIBUTOR GEARS) AND OIL RESERVOIR - CHECK
OIL LEVEL
Legend for illustration Z 20696
PUMP DISTRIBUTOR GEARS, CHECK OIL LEVEL:
OTICE
Checking of the oil level in both PTO gears must be carried
out at the scheduled intervals, also on excavators equipped
with an oil loss sensor. This sensor does not monitor the oil
level but shuts down the excavator in case of a massive oil
loss.
1. Unscrew level gauge (1) and wipe it clean.
2. Insert gauge (1), but DO NOT screw in, see detail (A).
3. Remove level gauge and read the oil level. The oil level
should be between the “MIN” and “MAX” mark. If necessary,
add oil through filler opening (2) up to the “MAX” mark on
gauge (1).
EMARK
If the oil level is above the “MAX” mark, drain the oil down
until the oil level is at the “MAX” mark. Too much oil in the pump
distributor gear will cause aeration of the oil.
4. Insert gauge (1) and tighten securely. Remove breather filter
(3). Blow out with compressed air from inside to outside and
reinstall.
