MAINTENANCE BASICS
7-3
CLEANING THE MACHINE
Always keep the machine clean. Ensure that grease nipples, air
vent holes, and oil level indicators are always clean. Avoid con-
tamination of operating agents with impurities. This will reduce
malfunctions to a minimum.
• If somebody accidentally lowers the bucket while cleaning
is being performed under the boom, this may lead to se-
vere accidents!
Before you start performing cleaning work under the
boom, either support the bucket or lower it onto the
ground.
If you have to perform cleaning work under the boom and you
cannot support the bucket, park and secure the machine as fol-
lows:
1. Park the machine on level ground.
2. Apply the parking brake.
3. Place wheel chocks in front of the wheels to prevent the ma-
chine from rolling away.
4. With the bucket in its dumping position, lower the bucket on-
to the ground with either its cutting edge or teeth.
PRECAUTIONARY MEASURES WHEN CLEAN-
ING THE MACHINE
• Do not point a water or steam jet directly at the radiator.
• Pay attention that water does not get into the electrical sys-
tem.
FIRE PREVENTION
Do not use any highly inflammable cleaning agents for cleaning
of parts.
If – by way of exception – you have to use inflammable cleaning
agents, keep the cleaning agent away from fire and do not
smoke while you are working.
