2.1 SAFETY INSTRUCTIONS
GAS, DUST, STEAM AND SMOKE
Operate internal combustion engines and fuel operated heat-
ing 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 expressly authorized, as there
may be a risk of explosion and fire. Special care must be
taken before welding, flame-cutting and grinding operations
are carried out on the counterweight. The filling of the coun-
terweight chambers can create explosive gases which will
accumulate in the chambers of the counterweight. These
gases must be expelled before welding, flame-cutting and
grinding operations are carried out on the counterweight.
Danger of explosion. Follow the instructions given in PARTS
& SERVICE NEWS No. AH04518 for expelling the gases
from the counterweight chambers.
Before carrying out welding, flame-cutting and grinding oper-
ations, clean the machine and its surroundings from dust and
other inflammable substances and make sure that the pre-
mises are adequately ventilated (risk of explosion).
HYDRAULIC AND PNEUMATIC EQUIPMENT
Work on hydraulic equipment may be carried out only by per-
sons having special knowledge and experience in hydraulic
systems.
Check all lines, hoses and screwed connections regularly for
leaks and obvious damage. Repair damage immediately.
Splashed oil may cause injury and fire.
Depressurize all system sections and pressure pipes
(hydraulic system, compressed-air system) to be removed in
accordance with the specific instructions for the unit con-
cerned before carrying out any repair work.
Hydraulic and compressed-air lines must be laid and fitted
properly. Ensure that no connections are interchanged. The
fittings, lengths and quality of the hoses must comply with the
technical requirements.
NOISE
During operation, all sound baffles must be closed. Always
wear the prescribed ear protectors.
OIL, GREASE AND OTHER CHEMICAL
SUBSTANCES
When handling oil, grease and other chemical substances,
observe the product-related safety regulations. Be careful
when handling hot consumables (risk of burning or scalding).
