Replacing the spark plug

G
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.
- Remove the fi lter cover (see "Cleaning the air fi lter").
- Pull the plug cap (G/1) off the spark plug. Use only the
combination wrench supplied with the saw to remove the
spark plug.
CAUTION: Use only the following spark plugs:

- Clean the air fi lter and prefi lter with a soft brush.
- If the fi lter is very dirty, clean it in lukewarm water with dish-
washing detergent.
- Let the air fi lter dry completely.
- Put the top and bottom sections back together.
- Before reinstalling the air fi lter, check the intake opening and
remove any dirt particles. If there are any, remove them with
a brush.
Clean frequently (several times a day) when working in very
dusty or dirty conditions. Full engine power is possible only with
a clean air fi lter and prefi lter!
Important: For sawing dry wood and working on dusty ground
we recommend using a Robkofl ok air fi lter (available as an
accessory). The Robkofl ok fi lter keeps out even the smallest
dust particles.
CAUTION: If the air fi lter or prefi lter becomes damaged,
replace immediately!
Pieces of cloth or large dirt particles can destroy the en-
gine!

If the function is correct, an ignition spark must be visible near
the electrodes.
