Dolmar PS-9010 - Cleaning the Air Fi Lter; Replacing the Spark Plug

21
Cleaning the air fi lter
- Demount the fi lter cover (A/1) (2 screws).
Caution: Pull the choke (A/2) to shut the choke shutter and
to prevent dirt particles from entering the carburetor.
- Loosen the two screws (A/4) and remove the air fi lter (A/3)
from the intake stack.
- Position a screw driver between the two latches and separate
the upper and lower part by turning it.
- Clean the air fi lter with a soft brush.
- If the fi lter is very dirty, clean it in lukewarm soapsuds with
standard detergent.
- Let the air fi lter dry completely.
- Assemble the upper and lower part and put them on the
intake stack. Firmly tighten the screws (A/4).
If the fi lter is very dirty, clean it frequently (several times a day),
because only a clean air fi lter guarantees full engine power.
CAUTION:
Replace damaged air fi lters immediately.
Torn off pieces of cloth may destruct the engine.
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 a damage of the
insulating body, consumption of the electrodes or if the elctrodes
are very dirty or oily.
- Loosen both screws of the fi lter cover (A/1) and remove
the fi lter cover (see fi g. clean air fi lter).
- Pull off the plug cap (C/3) from the spark plug. Only use
the universal wrench delivered with the chain saw for de-
mounting.
- Mount the new spark plug in the reverse order.
CAUTION: Use only the following spark plugs:
NGK BPMR 7A or BOSCH WSR 6F.
Electrode gap
The electrode gap must be 0.5 - 0.8 mm.
Checking the ignition spark
- Press the loosened spark plug with the fi rmly connected
ignition cable against the cylinder by means of insulated
pliers (not near the spark plug opening).
- ON/OFF switch in START position "I".
- Start the engine by forcefully pulling out the starter cable.
If the function is correct, an ignition spark must be visible near
the electrodes.
