12.2 Checking the oil level (Fig. 7)
1. Proceed as described in 9.3.
12.3 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 sur-
face.
2. Provide a collection container (not included in the
scope of delivery).
3. Remove the oil dipstick (21). Remove the oil drain
screw (22) with a 10 mm open­ended spanner (B)
to let the oil drain out.
4. Screw the oil drain screw (22) back in.
5. Fill up with new engine oil (max. 110 ml).
6. Screw the oil dipstick (21) in again.
7. Dispose of the used oil properly.
12.4 Air filter (Fig. 9, 10)
NOTE!
Risk of damage!
Operating the engine without a filter element or with
a damaged filter element can cause engine damage.
- Never run the engine without the air filter element or
with a damaged filter element. This would allow dirt
into the engine, which would result in severe dam-
age to the engine.
Clean the air filter (23) every 50 operating hours, re-
place if necessary.
1. Remove the grip screw (23a) (Fig. 9).
2. Open up the air filter housing (23).
3. Remove the foam insert (23b).
4. Do not use harsh cleaners or petrol to clean the
filter.
5. Clean the elements by knocking them out on a flat
surface. If heavily soiled, wash with soapy water,
then rinse with clean water and allow to air dry.
6. The re-assembly takes place in reverse order.
12.5 Charge the battery (9) with a car battery
charger (Fig. 1)
m DANGER!
Danger due to charging the battery incorrectly!
If the charging voltage is too high, there is a risk of the
battery (9) exploding.
Always remove the ignition key (14) from the ignition
(14a) when working on the battery (9).
- The charging current of the battery charger must
not exceed 5 A and the charging voltage must not
exceed 14.4 V.
1. Remove the battery (9) as described in Section
13.2.
2. Connect the battery (9) to a suitable car battery
charger. Then connect the red cable to the posi-
tive terminal (+) and the black cable to the nega-
tive terminal (­) of the charging unit.
3. Charge the battery (9) for at least 5 hours.
Attention!
Danger of short circuit!
- To avoid a short circuit, always disconnect the nega-
tive cable (­) from the battery (9) first and reconnect
it last.
- When connecting/disconnecting the battery connec-
tion cable (17a), make sure that the poles (+/­) do not
touch each other and/or the frame.
12.5.1 Spark plug (Fig. 11)
m ATTENTION: Only replace the spark plug when
the engine is cold!
Check the spark plug (20a) for contamination for the
first time after 20 operating hours and clean it with a
copper wire brush if necessary. Then maintain the
spark plug (20a) every 50 operating hours.
1. Pull off the spark plug connector (18) with a twist-
ing motion.
2. Remove the spark plug (20a) with the enclosed
spark plug wrench (A).
3. Remove any dirt from the base of the spark plug
(20a).
4. Visually inspect the spark plug (20a). Remove any
deposits present using a wire brush.
5. Check the spark plug gap. Set the electrode gap to
0.7 to 0.8 mm with a feeler gauge.
6. The re-assembly takes place in reverse order.
NOTE
A loose spark plug can overheat and cause damage
to the engine. Tightening the spark plug too much can
damage the thread in the cylinder head.
12.6 Clean fuel filter insert
Note: The fuel filter insert is a filter cup which is locat-
ed directly under the fuel filler cap (1) and filters all the
fuel filled in.
1. Rotate the fuel valve (14) to the" OFF" position.
2. Open the fuel filler cap (1).
