TECHNICAL HANDBOOK LW 50
For carrying out overhead assembly work always
use specially designed or otherwise safety-ori-
ented ladders and working platforms. Never use
machine parts as a climbing aid.
Wear a safety harness when carrying out main-
tenance work at greater heights.
Keep all handles, steps, handrails, platforms,
landings and ladders free from dirt, snow and ice.
Clean the machine, especially connections and
threaded unions, of any traces of oil, fuel or
preservatives before carrying out mainten-
ance/repair. Never use aggressive detergents.
Use lint-free cleaning rags.
Before cleaning the machine with water, steam jet
(high-pressure cleaning) or detergents, cover or
tape up all openings which - for safety and func-
tional reasons - must be protected against water,
steam or detergent penetration. Special care must
be taken with electric motors and switchgear
cabinets.
Ensure during cleaning of the machine that the
temperature sensors of the fire-warning and fire-
fighting systems do not come into contact with
hot cleaning agents as this might activate the
fire-fighting system.
After cleaning, remove all covers and tapes ap-
plied for that purpose.
After cleaning, examine all fuel, lubricant, and
hydraulic fluid lines for leaks, loose connections,
chafe marks and damage. Any defects found
must be rectified without delay.
Always tighten any screwed connections that
have been loosened during maintenance and re-
pair.
Any safety devices removed for set-up, main-
tenance or repair purposes must be refitted and
checked immediately upon completion of the
maintenance and repair work.
Ensure that all consumables and replaced parts
are disposed of safely and with minimum envi-
ronmental impact.

Warning of special dangers
Electric energy
Use only original fuses with the specified current
rating. Switch off the machine immediately if trou-
ble occurs in the electrical system.
When working with the machine, maintain a safe
distance from overhead electric lines. If work is to
be carried out close to overhead lines, the work-
ing equipment must be kept well away from them.
Caution, danger! Check out the prescribed safety
distances.
If your machine comes into contact with a live
wire
- do not leave the machine
- drive the machine out of the hazard zone
- warn others against approaching and touching
the machine
- have the live wire de-energized
- do not leave the machine until the damaged
line has been safely de-energized.
The electrical equipment of machines is to be
inspected and checked at regular intervals. De-
fects such as loose connections or scorched ca-
bles must be rectified immediately.
Gas, dust, steam and smoke
Operate internal combustion engines and fuel-
operated heating systems only on adequately
ventilated premises. Before starting the machine
on enclosed premises, make sure that there is
sufficient ventilation.
Observe the regulations in force at the respective
site.
Carry out welding, flame-cutting and grinding
work on the machine only if this has been ex-
pressly authorized, as there may be a risk of
explosion and fire.
Before carrying out welding, flame-cutting and
grinding operations, clean the machine and its
surroundings from dust and other inflammable
substances and make sure that the premises are
adequately ventilated (risk of explosion).
