Pay special attention to:
"Fundamental Safety Instructions",
"Inspection and Servicing, Safety In-

attached to the machine.
The descriptions of operational se-
quences are designed for experi-
enced personnel only.
Always keep the Operation and Main-
tenance Instruction Manual with the

how and experience relevant to the

SAFETY INSTRUCTIONS
PRETENSIONED UNITS
Never open damaged pretensioned
units but replace them as complete
units.
Open them only in exceptional cases
where the system and the working
sequence are exactly known and the
necessary special tools are avail-
able.
The Operation and Maintenance In-
struction Manual contains no rele-
vant information.
DISMANTLING COMPONENTS
Never dismantle components while
the machine is still at operating tem-
perature.
Oils, greases, brake fluid or coolant
may have a high temperature and
thus result in burning or scalding.
Wait for the machine to cool down.
Depressurize pipelines and hoses,
cylinders, radiator, hydraulic tank,
compressed air reservoir and other
systems or units before starting
work.
Replace defective components in
g o o d t i m e t o p r e v e n t g r e a t e r
damage.
Clean the defective component care-
fully before dismantling it. Mark dis-
mantled components in the correct
sequence to facilitate installation.
When dismantling the component,
close exposed hose and pipe con-
nections, open boreholes and hous-
ings with care to prevent dirt from
penetrating.
