• Drain the used oil into a suitable collection container.

• Finally, re-assemble everything in reverse order.

• When lling the new oil, bear in mind that you

should not ll the recommended quantity of oil at

once, as small quantities of oil always remain dur-

ing an oil change.

• Check the oil level as described in the “Checking

the oil level” point.

• Dispose of the oil in accordance with stipulations.

Take the old oil to a collection point. Most petrol

stations, garages or recycling centres take back old

oil free of charge.

Air lter

Frequently cleaning of the air lter prevents carbu-

retor malfunction. Clean the air lter regularly, espe-

cially when working in dusty environments.

ash point to clean the air lter element. A re or ex-

plosion could result.

Note

Never run the engine without or with a damaged air

lter. Dirt gets so into the engine, causing serious

engine damage can occur. In this case, seller, and

manufacturer disassociate from any warranty.

the spark plug.

8.4 Electrical safety

Electrical cables and attached devices must be de-

fect free.

Never connect the generator to the mains (power

point).

Keep the cables as short as possible.

8.5 Connecting to earth

The housing can be connected to earth to discharge

static electricity. To do this, connect one end of a ca-

ble to the earthing connection (3) on the generator

and the other end to an external ground (z. B. for ex-

ample to an earthing rod).

At the 12 V DC connection (14), a 12 V battery can be

charged using the included cable (A).

load indicator light illuminates red, the reset button

cator light (green) illuminates. If the overload protec-

tion was not triggered, the reset button does not have
