11.4 Clean the air filter (19) (Fig. 7)
ATTENTION
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 (19) every 50 operating hours, replace
if necessary.
1. Remove the engine cover (3).
2. Remove the wing screw (17).
3. Unfold the air filter cover (18).
4. Remove the air filter (19).
5. Do not use harsh cleaners or petrol to clean the filter.
6. 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.
7. The re-assembly takes place in reverse order.
11.5 Check spark plug (20) (Fig. 11+12)
ATTENTION
Only replace the spark plug when the engine is cold!
Check the spark plug for dirt for the first time after 20 op-
erating hours and clean it with a copper wire brush if nec-
essary. Then service the spark plug every 50 operating
hours.
1. Open the spark plug cover (4).
2. Pull off the spark plug connector (21) with a twisting
motion.
3. Remove the spark plug (20) with the enclosed spark
plug wrench (15).
4. Remove any dirt from the base of the spark plug (20).
5. Visually inspect the spark plug (20). Remove any de-
posits present using a wire brush.
6. Check the spark plug gap. Set the electrode gap to
0.6 to 0.7 mm with a feeler gauge.
7. 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.
11.6 Cleaning the fuel filter insert (22)
(Fig. 13+14)
Note:
The petrol filter is a fuel filter insert cup, which is located
directly under the fuel cap and filters all the fuel that is
filled in.
1. Set the on/off switch (13) to the "OFF" position.
2. Open the fuel filler cap (2).
3. Remove the fuel filter insert (22) and the fill level
marking (23). Clean it in a non-flammable solvent or a
solvent with a high flash point.
4. Reinsert the fuel filter insert (22) with the fill level
marking (23).
5. Close the tank cover (2).
12 Storage
DANGER
Risk of fire and explosion!
Storing the product near potential sources of ignition
can result in a fire or an explosion. This can lead to se-
vere burns or death.
– Eliminate possible sources of ignition, such as fur-
naces, hot water boilers with gas, gas dryers, etc.
ATTENTION
Risk of damage!
If the product is not stored properly, the engine can be
damaged.
– Store the product protected against dirt, dust and
moisture.
12.1 Preparation for storage
WARNING
Do not remove the fuel in enclosed spaces, near fire or
when smoking. Petrol fumes can cause explosions and
fire.
1. Empty the fuel tank using a petrol extraction pump.
2. Start the engine and let it run until the remaining fuel
is used up.
3. Store fuel in tanks specifically designed for this pur-
pose.
4. Change the oil at the end of every season.
5. To do so, remove the used engine oil from a warm en-
gine and refill with fresh oil.
6. Remove the spark plug (20).
7. Fill the cylinder with approx. 20 ml of oil from an oil
can.
8. Pull the pull starter slowly so that the oil protects the
inside of the cylinder.
9. Screw the spark plug (20) back in (Fig. 12).
10. Store the product in a well-ventilated place or area.
12.2 Drain fuel with a petrol extraction
pump (Fig. 13)
In case of storage over a longer period of time, the fuel
must be drained.
1. Hold a collection container under the hose of the petrol
extraction pump (not included in the scope of delivery).
2. Unscrew and remove the fuel filler cap (2).
3. Remove the fuel filter insert (22).
