Maintenance
BOMAG56 BMP 8500
5.1 General notes on mainte-
nance
When performing maintenance work always com-
ply with the appropriate safety regulations.
Thorough maintenance of the machine guaran-
tees far longer safe functioning of the machine and
prolongs the lifetime of important components.
The effort needed for this work is only little com-
pared with the problems that may arise when not
observing this rule.
The terms right/left correspond with travel direc-
tion forward.
l Always clean machine and engine thoroughly
before starting maintenance work.
l For maintenance work stand the machine on
level ground.
l Always remove the main battery switch for all
maintenance work.
l Perform maintenance work only with the motor
switched off.
l Relieve hydraulic pressures before working on
hydraulic lines.
l Before working on electric parts of the ma-
chine disconnect the battery and cover it with
insulation material.
l When working in the area of the articulated
joint attach the articulation lock (transport
lock).
During maintenance work catch all oils and fu-
els and do not let them seep into the ground or
into the sewage system. Dispose of oils and fu-
els environmentally.
Keep used filters in a separate waste container
and dispose of environmentally.
Catch biodegradable oils separately.
Notes on the fuel system
The lifetime of the diesel engine depends to a
great extent on the cleanliness of the fuel.
l Keep fuel free of contaminants and water,
since this will damage the injection elements
of the engine.
l Drums with inside zinc lining are not suitable to
store fuel.
l When choosing the storage place for fuel
make sure that spilled fuel will not harm the en-
vironment.
l Do not let the hose stir up the slurry at the bot-
tom of the drum.
l The fuel drum must rest for a longer period of
time before drawing off fuel.
l The rest in the drum is not suitable for the en-
gine and should only be used for cleaning pur-
poses.
Notes on the performance of the en-
gine
On diesel engines both combustion air and fuel in-
jection quantities are thoroughly adapted to each
other and determine power, temperature level and
exhaust gas quality of the engine.
If your engine has to work permanently in "thin air"
(at higher altitudes) and under full load, you should
consult the customer service of BOMAG or the
customer service of the engine manufacturer.
Notes on the cooling system
Prepare and check coolant with highest care,
since otherwise the engine may be damaged by
corrosion, cavitation and freezing.
The coolant is prepared by mixing a cooling sys-
tem protection agent (ethylene glycol) into the
coolant.
Mixing with cooling system protection agent is
necessary in all climatic zones. It prevents corro-
sion, lowers the freezing point and raises the boil-
ing point of the coolant.
Notes on the hydraulic system
During maintenance work on the hydraulic system
cleanliness is of major importance. Make sure that
no dirt or other contaminating substances can en-
ter into the system. Small particles can produce
flutes in valves, cause pumps to seize, clog noz-
zles and pilot bores, thereby making expensive re-
pairs inevitable.
l If, during the daily inspection of the oil level the
hydraulic oil level is found to have dropped,
check all lines, hoses and components for
leaks.
