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

Engine oil
Quality
For use in DEUTZ engines the lubrication oils are
classified in DEUTZ Lubrication Oil Quality Class-
es (DQC).
Use only oils complying with DQC III-05, DQC III-
10 or DQC IV-05 or DQC IV-10 respectively.
The list of approved lubrication oils is also availa-
ble in the Internet under the following address:
Consult your local service station if in doubt.
l
Use winter grade engine oil for winter opera-
tion!
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) .
Too high viscosity can cause starting difficulties,
too low ´viscosity can jeopardize the lubrication ef-
fect and result in a high lubrication oil consump-
tion.
