Fuels And Lubricants - Bomag BW 100 AD-4 Operating Instructions Manual

Seal external leaks immediately. If necessary
l
inform the responsible customer service.
Do not store drums with hydraulic oil outdoors,
l
or at least under a cover. Water can be drawn
in through the bunghole when the weather
changes.
We recommend to use the BOMAG filling and
l
filtering unit with fine filter to fill the system.
This ensures finest filtration of the hydraulic
oil, prolongs the lifetime of the hydraulic oil fil-
ter and protects the hydraulic system.
Clean fittings, filler covers and the area around
l
such parts before disassembly to avoid enter-
ing of dirt.
Do not leave the tank opening unnecessarily
l
open, but cover it so that nothing can fall in.

Engine oil
Quality
Lubrication oils are classified according to their
performance and quality class. Oils according to
other comparable specifications may be used.
If low sulphur fuel (< 0.05%) is used, you must only
use engine oils of API
CG-4, CH-4 and CI-4.
For operation of an engine with high sulphur fuels
it is recommended to use an engine oil of classifi-
cation CF or higher with a total base number of at
least 10.
Caution
!
Engine oils of classification CJ-4 must not be
used!
Oil viscosity
Since lubrication oil changes its viscosity with the
temperature, the ambient temperature at the oper-
ating location of the engine is of utmost impor-
tance when choosing the viscosity class (SAE-
class) .
Optimal operating conditions can be achieved by
using the following oil viscosity chart as a refer-
ence.
Ambient temperature
over 25 °C!
0°C to 25°C
below 0 °C
Oil change intervals
The longest permissible time a lubrication oil
should remain in an engine is 1 year. If the follow-
