2 SAFETY AND ACCIDENT PREVENTION
2.14 MHL380 D
2.3.3 Cleaning the machine
 Before starting maintenance or repair work,
clean any oil or fuel off the machine, paying
particular attention to the connections and
screw couplings. Do not use any aggressive
cleaning agents and use lint-free rags.
 Do not use any aggressive cleaning agents
or high-pressure cleaners to clean the
machine during the first two months after it
has been put into operation or after it has
been repainted. This will allow the paint to
cure completely.
 Do not use flammable liquids to clean the
machine.
 Before cleaning the machine with water,
high-pressure cleaners, or other cleaning
agents:
- Lubricate all bearing points, bolt
connections, and the slewing ring to
prevent the ingress of water and steam
into the bearing points.
- Close off or glue shut all openings which
water, steam, or cleaning agent must not
be allowed to penetrate for safety and/or
other reasons. Electrical motors, electrical
components, switch cabinets, plug
connections and air cleaners are
particularly at risk. Propshafts with
maintenance-free bearing bushings must
also not be cleaned with a high-pressure
cleaner. Doing so could have a
detrimental effect on the three-lip seal.
 After cleaning:
- Remove the covers completely.
- Inspect all fuel, engine oil and hydraulic
fluid lines for leaks, loose connections,
abrasion and damage.
- Correct any defects discovered
immediately.
- Lubricate all bearing points, bolt
connections and the slewing ring to force
out any water or cleaning agent that may
have entered.
