Cleaning the guide bar, lubricating the sprocket nose
CAUTION: Protective gloves must be worn.
Regularly inspect the bearing surfaces of the guide bar for damage, and clean them with a suitable
tool.
Sprocket nose type:
If the saw is used intensively it will be necessary to lubricate the return sprocket bearings regularly
(once a week). To do this, first thoroughly clean the 2 mm hole at the tip of the guide bar, and then
press in a small amount of multi-purpose grease.
Multi-purpose grease and grease guns are available as accessories.
Multi-purpose grease 944 360 000
Grease guns 944 350 000
Replacing the saw chain
CAUTION: Use only chains and guide bars designed for this saw.
Check the sprocket (10) before mounting a new chain.
CAUTION: Worn out sprockets may damage the new chain and must therefore be replaced.
Replacing the suction head
The felt filter (12) of the suction head can become clogged. It is recommended to replace the suc-
tion head once every three months in order to ensure unimpeded fuel flow to the carburetor.
To remove the suction head for replacement, pull it out through the tank filler neck using a piece of
wire bent at one end to form a hook.
Cleaning the air filter
Unscrew screw (14) and remove the cleaner case cover (13).
IMPORTANT: Cover the intake opening with a clean cloth in order to prevent dirt particles from fall-
ing into the carburetor. Remove the air filter. (15)
CAUTION: To prevent injury to the eyes, do NOT blow out dirt particles! Do not use fuel to
clean the air filter.
Clean the air filter with a soft brush.
If the filter is very dirty, clean it in lukewarm water with dishwashing detergent.
Let the air filter dry completely.
If the filter is very dirty, clean it frequently (several times a day), because only a clean air filter pro-
vides full engine power.
CAUTION:
Replace damaged air filters immediately.
Pieces of cloth or large dirt particles can destroy 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 damage to the insulator, electrode erosion (burn) or if
the electrodes are very dirty or oily.
Remove the cleaner case cover (see “Cleaning the air filter”).
Pull the plug cap (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 CMR6A.
