13.6 Cleaning/replacing the spark plug
(Fig. 15 + 16)
m ATTENTION: Only replace the spark plug when the en-
gine is cold!
Check the spark plug for dirt and grime after 10 operating
hours and if necessary, clean it with a copper wire brush.
Thereafter, replace the spark plug every 50 operating hours
if necessary.
1.
Disconnect the spark plug connector (21) and remove
any dirt in the spark plug area.
2.
Unscrew the spark plug (22) with the supplied spark plug
wrench (20).
3.
Check the insulation. Replace the spark plug (22) if it is
damaged, e.g. cracked or fragmented.
4.
Clean the spark plug electrodes with a wire brush.
5.
Check the electrode gap and adjust it using a feeler
gauge. To make sure that the engine remains efficient,
the spark plug must have the right electrode gap (0.6 -
0.7 mm).
6.
Screw the spark plug (22) back in by hand and tighten it
about 1/4 turn with the spark plug wrench (20) supplied.
7.
Place the spark plug connector (21) on the spark plug
(22).
m ATTENTION!
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.

14. Storage
m DANGER!
Risk of fire and explosion!
Storing the product near potential sources of ignition can result
in a fire or an explosion. This leads to severe burns or death.
- Eliminate possible sources of ignition, such as furnaces, hot
water boilers with gas, gas dryers, etc.
NOTE!
Risk of damage!
If the product is not stored properly, the engine can be dam-
aged.
- Store the product protected against dirt, dust and moisture.
14.1 Storage during extended breaks in operation:
If the device will not be used for a period of more than 30
days, follow the steps below to prepare it for storage.
1.
Put the cutting roller into the uppermost position using the
working height adjustment (12).
2.
Empty the fuel tank completely (see section 13.4). Stored
petrol containing ethanol or MTBE becomes stale within
30 days. Stale petrol has a high rubber content and can
thus clog the carburettor and restrict the petrol supply.
3.
Drain the engine oil from the engine while it is still warm.
Top up with new oil. (See section 13.3.)
4.
Use clean cloths to clean the petrol scarifier.
m Do not use aggressive or oil-based clean-
ing agents when cleaning the plastic parts.
Chemicals can damage plastics.

Dismantle the push bar if necessary. Ensure that the cable
pull is not kinked.
