General notes on maintenance

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
important components. The necessary effort can
by no means be compared with the problems and
malfunctions that could occur if this is not observed.
The terms left/right are always related to travel direction
forward.
Clean machine and engine thoroughly before
•
starting maintenance work.
For maintenance work park the machine on level
•
ground.
Maintenance work must generally be carried out
•
with the engine shut down.
Depressurize hydraulic lines before working on
•
them.
Disconnect the battery and cover it with
•
insulation material before starting to work on
electrical components.
Always attach the articulation lock (transport
•
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 depending
on the cleanliness of the fuel.
Keep the engine free of dirt and water as this
•
could damage the injection elements of the
egine.
Zinc lined drums are not suitable for storing fuel.
•
The fuel drum should rest for a longer period of
•
time before drawing off fuel.
Do not let the suction hose disturb the sludge on
•
the bottom of the drum.

MAINTENANCE
Do not draw off fuel from near the bottom of the
•
fuel drum.
Fuel left in the fuel drum is not suitable for the
•
engine and should only be used for cleaning
puposes.

Notes on the engine performance

Combustion air and fuel injection rates of the diesel
engine have been carefully adjusted and determine
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 manufacturer.

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
•
found to have dropped, check all lines, hoses and
components for leakages.
Seal external leaks immediately. If necessary
•
inform the responsible service department.
Do not store drums with hydraulic oil outside, 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
•
and filtering unit (BOMAG part-no. 007 610 01).
This unit is equipped with a fine filter, which
filters the hydraulic oil and prolongs the lifetime
of the system filter.
Clean fittings, filler caps and their immediate
•
surrounding area before removing them, so that
no dirt can fall in.
Do not leave the tank opening unnecessarily
•
open, cover it so that no dirt can fall in.
