flutes in valves, cause pumps to seize, clog noz-
zles and pilot bores, thereby making expensive re-

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 our filling and filtering
unit with fine filter to fill the system. This en-
sures finest filtration of the hydraulic oil, pro-
longs the lifetime of the hydraulic oil filter 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.

Quality
For use in DEUTZ engines the lubrication oils are
classified in DEUTZ Lubrication Oil Quality Class-
es (DQC).
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!
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) .
