5.1 General notes on mainte-
nance
When servicing the machine pay careful attention
to all applicable safety instructions.
Thorough maintenance of the machine ensures
maximum reliability and prolongs the lifetime of im-
portant components. The necessary effort can by
no means be compared with the problems and
malfunctions that could occur if this is not ob-
served.
The terms left/right are always related to travel di-
rection forward.
Clean machine and engine thoroughly before
l
starting maintenance work.
For maintenance work park the machine on
l
level ground.
Maintenance work must generally be carried
l
out with the engine shut down.
Depressurize hydraulic lines before working
l
on them.
Disconnect the battery and cover it with insu-
l
lation material before starting to work on elec-
trical components.
Always attach the articulation lock (transport
l
lock) before starting to work in the articulation
area of the machine.
Environment
Catch running out oils, coolant and fuel and do
not let them seep into the ground or into the
sewage system. Dispose of oils, coolant and
fuels environmentally.
Notes on the fuel system
The lifetime of the diesel engine is decisively de-
pending on the cleanliness of the fuel.
Keep the engine free of dirt and water as this
l
could damage the injection elements of the en-
gine.
Zinc lined drums are not suitable for storing fu-
l
el.
The fuel drum should rest for a longer period
l
of time before drawing off fuel.
4 8
Do not let the suction hose disturb the sludge
l
on the bottom of the drum.
Do not draw off fuel from near the bottom of
l
the fuel drum.
Fuel left in the fuel drum is not suitable for the
l
engine and should only be used for cleaning
purposes.
Notes on the engine performance
Combustion air and fuel injection rates of the die-
sel engine have been carefully adjusted and deter-
mine the engine's performance and temperature
level as well as the quality of the exhaust gas.
If your machine has to operate permanently in
"thin air" (at high altitudes) and with full power, you
should consult the after sales service of BOMAG
or the service department of the engine manufac-
turer.
Notes on the hydraulic system
During maintenance work in the hydraulic system
cleanliness is of utmost importance. Make sure
that no dirt or other impurities can enter into the
system. Small particles can flute valves, cause
pumps to seize and block restrictors and pilot
bores, thereby causing costly repairs.
If during the daily oil level check the oil level is
l
found to have dropped, check all lines, hoses
and components for leakages.
Seal external leaks immediately. If necessary
l
inform the responsible service department.
Do not store drums with hydraulic oil outside,
l
or at least keep them under a cover. During
weather changes water may penetrate
through the bunghole.
Always fill the hydraulic system using the filling
l
and filtering unit (BOMAG part-no.
007 610 01). This unit is equipped with a fine
filter, which filters the hydraulic oil and pro-
longs the lifetime of the system filter.
Clean fittings, filler caps and their immediate
l
surrounding area before removing them, so
that no dirt can fall in.
Do not leave the tank opening unnecessarily
l
open, cover it so that no dirt can fall in.
