Working on hydraulic lines
Always relieve the pressure in the hydraulic circuit
before working on hydraulic lines. Hydraulic oil es-
caping under pressure may penetrate through the
skin and cause severe injury. In case of being in-
jured by hydraulic oil you should immediately seek
medical advice, as otherwise this may lead to se-
rious infections.
When adjusting the hydraulic system do not stand
behind or in front of the drum/wheels.
Do not change the setting of high pressure relief
valves.
Drain hydraulic oil at operating temperature - dan-
ger of scalding!
Catch running out hydraulic oil and dispose of en-
vironmentally.
Always catch and dispose of biological hydraulic
oils separately.
Do not start the engine after draining off the hy-
draulic oil.
Once all work is completed (with the system de-
pressurized!) check all connections and fittings for
tight and leak-free fit.
Changing hydraulic hoses
All hydraulic hoses must be inspected visually at
regular intervals.
Hydraulic hoses must be changed immediately if:
the outer layer is worn down to the metal lining
l
(e.g. chafing, cuts, cracks)
embrittlement of the outer layer (development
l
of cracks in the hose material)
deformation under pressurized and depressu-
l
rized condition, which are not in accordance
with the normal shape of the hydraulic hose
deformation in bends, e.g, squeezes, kinks,
l
layer separation, formation of blisters
leakages.
l
non-observance of the installation require-
l
ments
separation of the hydraulic hose from the fit-
l
ting
corrosion of the fitting, which impairs the func-
l
tion and the strength.
1 6
Do not mix up hoses by mistake.
l
damage or deformation of the fitting, which im-
l
pairs the function and strength of the hose/
hose connection.
Only genuine BOMAG hydraulic hoses ensure
that the correct type of hose (pressure range) is
used at the right place.
Working on the engine
Shut the engine down before opening the engine
compartment hood.
Drain the engine oil at operating temperature -
danger of scalding!
Wipe off spilled oil, catch running out oil and dis-
pose of environmentally.
Store used filters and other oily materials in a sep-
arate, specially marked container and dispose of
environmentally.
Do not leave any tools or other objects, which
could cause damage, in the engine compartment.
Idle speed and full load speed must not be
changed, since this would have a negative effect
on the exhaust gas values and cause damage to
engine and drive.
Turbo chargers work with high speeds and high
temperatures. Keep hands, tools and materials
away from the intake and outlet openings of the
turbo charger and do not touch any hot surfaces.
Check and replace the coolant only when the en-
gine is cold.
Catch running out coolant and dispose of environ-
mentally.
Working on electrical equipment
Before working on electrical equipment disconnect
the battery and cover it with insulating material.
Do not use any fuses with higher ampere ratings
or repair a fuse with a piece of wire. Fire hazard!
Always disconnect the battery before starting to
wled on the machine.
Working on the battery
When working on the battery do not smoke, do not
use open fire.
Do not let acid come in contact with skin and
clothes. If being injured by acid flush off with clear
water and seek for medical advice.
