10.1 Cleaning
Keep protective devices, air vents and the motor hous-
ing as free of dust and dirt as possible. Rub the device
clean with a clean cloth or blow it o with compressed
air at low pressure. We recommend that you clean the
device directly after every use.
Clean the device at regular intervals using a damp
cloth and a little soft soap. Do not use any cleaning
products or solvents; they could attack the plastic parts
of the device. Make sure that no water can penetrate
the device interior.
10.2 Maintenance
WARNING!
Always wear protective gloves and a mask during
maintenance work!
10.3 Check the oil level (g. 7 + 8)
1. Proceed as described under 8.1.
10.4 Oil change
Change the engine oil after 20 operating hours, then
after 50 hours or every three months.
The engine oil change should be carried out while the
engine is at operating temperature.
1. Place the power generator on a level, even surface.
2. Remove the engine cover (3) as described in 9.1.
(Fig. 7)
3. Provide a collection container (not included in the
scope of delivery).
4. Open the oil dipstick (16) and drain warm engine
oil into the collection container by tilting the power
generator.
5. Fill up with new engine oil (approx. 0.35 l).
6. Screw the oil dipstick (16) in again.
7. Dispose of the used oil properly.
10.5 Air lter (Fig. 10)
NOTE!
Risk of damage!
Operating the engine without a lter element or with
a damaged lter element can cause engine damage.
- Never run the engine without the air lter element or
with a damaged lter element. This would allow dirt
into the engine, which would result in severe dam-
age to the engine.
