8.1 Maintenance notes
DANGER
- The engine must be turned off.
- When working under the bucket arm:
- the bucket must be emptied or the attachment
must be relieved,
- the bucket arm must be mechanically propped up
[e.g. by inserting the bucket arm support (option)
(1-1/arrow)],
- the ball block valve for the working and auxiliary
hydraulics (1-2/arrow) must be closed,
- the swivel mechanism is to be blocked (1-4/
arrow).
- The loader is to be secured against rolling by using
the parking brake (4-7/14) or by setting the drive
direction switch (4-7/13) to the “0” position. In
addition, wedges must be placed on both sides of
one of the two wheels of the front axle.
CAUTION
- Change the oil when the units are lukewarm.
- Check the oil level when the loader is on level
ground and the bucket arm is in its lowest position.
- Replace damaged filter inserts and gaskets imme-
diately.
- Clean pressure lubrication fittings before lubrica-
ting.
N O T E
- All necessary maintenance work is to be taken from
the maintenance plan.
- Damage which is traceable to non-observance of
the maintenance plan is not covered by the guarantee.
- The lubricants mentioned in the maintenance plan
may be used at an ambient temperature from
-15° to +40°C .
CAUTION
For ambient temperatures below -15 °C, refer to the
description given in section 5.2.2, “Winter operation”.
N O T E
If a hose and/or pipe break occurs, the lid of the hydraulic
oil filter (8-17/arrow) must be loosened because the loader
does not have a locking cock that could prevent large
amounts of hydraulic oil from escaping.
