8. Maintenance
Shut down the engine before doing any cleaning and
maintenance work on the unit.
Remove dust and dirt from the machine at regular
intervals. Cleaning is best carried out with a fine
brush or a cloth.
Never use caustic agents to clean plastic parts.
Take the diesel mixture out of the generator if you
do not intend to use it for a lengthy period of time
Important: Switch off the machine immediately
and contact your service station:
In the event of unusual vibrations or noise.
If the engine appears to be overloaded or runs
unevenly.
8.1 Changing the oil and checking the oil level
(before using the machine)
The engine oil should be changed for the first time
when the engine is warm after approx. 20 hours of
service. After this the engine oil must be changed
every 150 hours of service when the engine is warm.
Use only engine oil (15W40)
Place the generator unit on a suitable flat surface
Undo the oil filler screw (Fig. 5/Item C)
Undo the oil drain screw (Fig. 5/Item D) and drain
the warm engine oil through the drain channel into
a container.
After all the oil has drained out, tighten the oil
drain screw and clean the drain channel with a
cloth.
Add engine oil up to the top mark on the oil
dipstick.
Important: Do not screw the dipstick in to check
the oil level, simply insert it up to the thread.
Dispose of the waste oil properly.
8.2 Cleaning the air filter (see Fig. 8-13)
Check the air filter before every use, clean or
replace it if necessary.
Do not use abrasive cleaning agents or petrol to
clean the elements.
Clean the elements by tapping them on a flat
surface.
8.3 Cleaning the diesel filter (Fig. 6)
The diesel filter (Fig. 6/Item G) must be cleaned if
impurities can be seen in the inspection window (Fig.
6/Item H). To clean the diesel filter you will need a
funnel connected to a petrol/diesel-resistant fuel
hose, petrol/diesel-resistant gloves and an empty
diesel fuel canister (IMPORTANT: never mix petrol
and diesel).
Close the fuel cock (Fig. 6/Item E).
Loosen the knurled nut (Fig. 6/Item F).
Insert the fuel hose connected to the funnel into
the diesel canister and hold the funnel under the
inspection window (Fig. 6/Item H).
Undo the knurled nut (Fig. 6/Item F) completely
and drain the clean residual quantity of diesel from
the inspection window into the funnel.
Mop up the contaminated residual quantity of
diesel using cleaning paper. Clean the inspection
window.
Pull the diesel filter downwards off the diesel filter
holder, remove the remains of the dirt on the
diesel filter with the cleaning paper using a little
diesel fuel if necessary, or if it is damaged replace
the diesel filter. Dispose of the cleaning paper.
Assemble in reverse order.
8.4 Draining the tank
To drain the tank, proceed initially as if you were
cleaning the diesel filter.
After removing the diesel filter, position the funnel
under the diesel filter holder (Fig. 6/Item I) and
open the fuel cock (Fig. 6/Item E).
Drain the diesel fuel out of the tank through the
funnel and into the diesel canister. (IMPORTANT:
Ensure that the diesel canister is large enough to
hold all the fuel left in the tank!).
If necessary the draining process can be stopped
by closing the fuel cock.
After the draining process has been completed, re-
assemble the device as described in point 8.3.
9. Winter operation
Since the generator is powered by a diesel engine,
special precautions must be taken for using it in the
winter.
Use “winter diesel” to operate the diesel generator in
outdoor temperatures between -3°C to -10°C. The
change to winter diesel takes place at different times
depending on the country concerned, it is general
around the end of October. You can ask at your
filling station when this change should be made.
