Replacing the spark plug
CAUTION:
Do not touch the spark plug or plug cap if the engine is
running (high voltage).
Switch off the engine before starting any maintenance
work.
A hot engine can cause burns. Wear protective gloves!
The spark plug must be replaced in case of damage to the
insulator, electrode erosion (burn) or if the electrodes are very
dirty or oily.
Turn the cover lock (
6
) to the ”Unlocked ” position and care-
fully remove the filter cover (
7
).
Flip up the spark-plug cover (
8
).
Pull the plug cap (
8
) off the spark plug. Use only the combination
wrench supplied with the saw to remove the spark plug.
Electrode gap
The electrode gap must be 0.5 mm.
Pre-filter
(foam)
and inner filter
If the pre-filter (
1
) and inner filter (
3
) are dirty, wash them out in
lukewarm water with regular dishwashing liquid.
Dry pre-filter and inner filter
thoroughly
.
NOTE:
The pre-filter needs cleaning at least daily, or more often
if the Power Cut is used in very dusty conditions. If cleaning on-
site is not possible, keep a replacement pre-filter on hand.
Replace the pre-filter after every 20 operating hours at the
latest.
To improve filtration, wet the pre-filter with air filter oil. Before
doing this, carefully clean the pre-filter with air filter cleaner. Be
sure to follow manufacturer’s instructions.
When inserting the pre-filter in the filter cover, align it with the
cover opening and press it into the cover (
5
).
Filter insert
(paper cartridge)
The air filter insert (
2
) filters the intake air through a very fine
paper fan filter system, so it must never be washed. Clean the
filter insert once weekly.
To do so, open it slightly and carefully tap it out against a clean
surface.
Replace the filter insert every 100 operating hours. Replace it
immediately if there is loss in power, loss in speed, or smoke
develops in the exhaust.
Before installing the filter system, check the intake opening for
any dirt particles that may have fallen in. If so, remove them.
CAUTION:
If the air filter becomes damaged, replace immediately!
Pieces of cloth or large dirt particles can destroy the en-
gine!
