2.6.3 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 ma-
chine 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 connec-
tions, and the slewing ring to prevent the
ingress of water and steam into the bear-
ing 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 con-
nections and air cleaners are particularly
at risk. Propshafts with maintenance-free
bearing bushings must also not be
cleaned with a high-pressure cleaner. Do-
ing 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 immedi-
ately.
- Lubricate all bearing points, bolt connec-
tions and the slewing ring to force out any
water or cleaning agent that may have en-
tered.
2.6.4 Repairs on the machine
Do not attempt to lift heavy parts. Use work
aids designed for this purpose with sufficient
carrying capacity. Fasten and secure individu-
al parts and large assemblies carefully on
lifting equipment so they cannot cause any
danger. Use only suitable lifting equipment
which is in perfect working order. Loads must
be supported by hoisting equipment with suffi-
cient carrying capacity. Do not stand or work
under suspended loads.
Do not use lifting equipment that is dam-
aged or does not have sufficient carrying
capacity. Wear protective gloves when
working with wire ropes.
Only experienced persons must be as-
signed the task of attaching loads and act-
ing as banksmen to guide crane drivers.
Banksmen must remain within the opera-
tor's range of vision or stay in voice contact.
For jobs above head height, use designated
climbing aids and work platforms that meet
safety requirements. Do not use machine
parts as climbing aids if they were not de-
signed for that purpose. Wear fall protection
for work performed at high heights. Keep all
grips, steps, platforms, and ladders, etc.
free of dirt, snow and ice.
When working on equipment, ensure there
is adequate support. Avoid metal-to-metal
contact.
Always support the machine so that any
shifting of weight will not endanger stability.
Avoid metal-to-metal contact.
Work on drive mechanisms, brake and
steering systems must only be performed by
specialist personnel trained for the task in
question.
If the machine needs to be repaired on an
incline, place blocks under the wheels to
secure them.
Only persons with specialist knowledge and
experience are permitted to perform work
on hydraulic equipment.
