CAUTION:
Pull the choke (E/2) to shut the choke valve and to prevent dirt
particles from entering the carburetor.
‑ Pull the air filter (E/3) off the carburetor.
‑ Cover the carburetor with a clean cloth.
‑ Grasp the top and bottom sections of the air filter as shown
in figure F and pull apart.

To prevent injury to the eyes, do NOT blow out dirt parti-
cles!
Do not use fuel to clean the air filter.

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 filter cover (see "Cleaning the air filter" above,
Fig. E/1).
‑ 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:
NGK BPMR 6F or CHAMPION RDJ-7Y.

‑ Clean the air filter with a soft brush.
‑ If the filter is very dirty, clean it in lukewarm water with dish‑
washing detergent.
Let the air filter dry completely.
‑
‑ Put the top and bottom sections back together.
‑ Before re‑installing the air filter, check the choke valve for
dirt particles. If there are any, remove them with a brush.
If the filter is very dirty, clean it frequently (several times a day),
because only a clean air filter provides full engine power.
Important:
For sawing dry wood and working on dusty ground we recommend
using a Robkoflok air filter (available as an accessory). The
Robkoflok filter keeps out even the smallest dust particles.
CAUTION:
Replace damaged air filters immediately. Pieces of cloth or
large dirt particles can destroy the engine!
