In most cases a sufficient cold resistance can also
be achieved by adding flow enhancing fuel addi-
tives. Consult the engine manufacturer.
Operation with rape seed oil methyl ester (RME
„Bio Diesel")
Due to the extreme quality differences of RMEW-
fuels available on the market, which are caused by
the non-existence of a standardization, BOMAG
does generally not approve any RME-fuels. If this
is neglected the warranty will become null and
void!
However, if you still intend to operate the machine
with RME-fuels you should observe the following
information:
Reduced engine power (approx. 7%), higher
l
fuel consumption.
The quality of RME-fuel should be in compli-
l
ance with DIN draft 51606.
Avoid longer periods of standstill (formation of
l
resin, corrosion in injection system)
RME-fuel can damage the paint finish of the
l
machine.
Fuel dilution of engine oil, therefore shortening
l
of oil change intervals to half.
Rubber parts, such as leak fuel return lines,
l
seats will be damaged in the long run and
need to be replaced on a regular basis or
should be replaced by parts made of fluorinat-
ed rubber. However, fluorinated rubber is not
resistant against normal diesel fuel.
If the fuel filter is clogged the filter change in-
l
tervals must be shortened accordingly.
Coolant, anti-freeze agent
Use only soft tap water (drinking water) to prepare
the coolant mix.
As a protection against frost, corrosion and boiling
point anti-freeze agents must be used under any
climatic conditions.
The proportion of cooling system protection agent
must be between min. 35% and max. 45% to the
water.
Caution
!
Do not mix different coolants and additives of
any other kind.
BW 213 D-4
Environment
Cooling system protection agents must be dis-
posed of environmentally.
Hydraulic oil
The hydraulic system is operated with hydraulic oil
HV 46 (ISO) with a kinematic viscosity of
2
46 mm /s at 40°C. For topping up or for oil chang-
es use only high-quality hydraulic oil, type HVLP
according to DIN 51524, part 3, or hydraulic oils
type HV according to ISO 6743/3. The viscosity in-
dex (VI) should be at least 150 (observe informa-
tion of manufacturer).
Bio-degradable hydraulic oil
On request the hydraulic system can also be filled
with ester based biodegradable hydraulic oil (Pan-
olin HLP Synth. 46). The biologically quickly de-
gradable hydraulic oil meets all demands of a
mineral oil based hydraulic oil according to DIN
51524.
In hydraulic systems filled with Panolin HLP Synth.
46 always use the same oil to top up. When
changing from mineral oil based hydraulic oil to an
ester based biologically degradable oil, you should
consult the lubrication oil service of the oil manu-
facturer for details.
Check the filter more frequently after this change.
Caution
!
Oil change bio-degradable hydraulic oil:
Perform regular oil analyses for content of wa-
ter and mineral oil.
Replace the hydraulic oil filter element every
500 operating hours.
Oil for drive axle
For the drive axle use only multi-purpose transmis-
sion oil of API-class GL5 with viscosity class SAE
90.
The additives in this oil ensure low wear lubrication
under all operating conditions.
Lubrication grease
For lubrication use only EP-high pressure grease,
lithium saponified (penetration 2).
