-
Loosen the screws (A/1) and remove the air fi lter cover
(A/2).
-
Take the foam fi lter out of the cover.
Caution: To prevent eye injuries, do not blow out dirt
particles!
-
Very dirty fi lters can be cleaned out using regular dishwash-
ing liquid in lukewarm water.
-
If it is very dirty clean it more often. Only a clean fi lter ensures
full engine power!
-
Before reinstalling the air fi lter check the choke valve for dirt
particles, and if necessary clean it out with a brush.
-
Carefully dry the air fi lter and reinstall it.
-
First insert the air fi lter cover (A/2) in the groove (A/4) and
then affi x with the screw (A/1).
Important: If the air fi lter is damaged replace it immediately!
Torn-off fabric pieces and large dirt particles can destroy
the engine!
CAUTION!
NEVER touch the spark plug or spark plug cap while the
engine is running (high voltage)!
Never do maintenance work with the engine running!
A hot engine can cause severe burns. Wear protective
gloves!
The spark plug must be replaced if the insulator is damaged or
if the electrodes are severely eroded or dirty or oily.
-
Pull the spark plug cap (B/6) off the plug. Remove the spark
plug with a spark plug wrench (19 mm size).
Note:
Replace only with NGK BPMR8Y spark plugs!
Electrode gap
The electrode gap must be 0.6 - 0.7 mm.
-
Insert the wrench (C/7) between the housing and the cylinder,
only as shown in the illustration.
CAUTION!
Do not insert the wrench into the spark plug hole. Make
contact only with the cylinder (otherwise you may damage
the engine).
-
Firmly connect the spark plug cap to the spark plug (removed
from the engine) and hold it against the wrench using insu-
lated pliers (away from the spark plug hole!).
-
Move the combination switch (I/O) to the "I" position.
-
Pull the starter cable hard.
A spark should be visible at the electrode gap.
