Sprocket nose type:
If the saw is used intensively it will be necessary to lubricate the return sprocket bear-
ings 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 (Fig. 55)
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 (Fig. 56)
The felt filter (12) of the suction head can become clogged. It is recommended to
replace the suction 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 (Fig. 57)
Unscrew screw (14) and remove the cleaner case cover (13).
IMPORTANT:
Cover the intake opening with a clean cloth in order to prevent dirt par-
ticles from falling 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 provides full engine power.
CAUTION:
Replace damaged air filters immediately.
Pieces of cloth or large dirt particles can destroy the engine!
Replacing the spark plug (Fig. 58)
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 ero-
sion (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.
Electrode gap (Fig. 59)
The electrode gap must be 0.6 – 0.7 mm.
Cleaning the inlet port of the cooling air (Fig. 60)
Unscrew four screws (2). Remove recoil starter (3).
Clean the inlet port (4) and the cylinder fins.
Cleaning the muffler (Fig. 61)
CAUTION: If the engine is hot there is a risk of burning. Wear protective gloves.
Remove the sprocket cover (see “PUTTING INTO OPERATION”).
Remove deposits of carbon from the exhaust outlets (11) of the muffler.
Cleaning the cylinder space (Fig. 62)
Remove the sprocket cover (see “PUTTING INTO OPERATION”).
If necessary remove muffler by loosening and removing the two screws (14).
Stuff a rag into the cylinder port (15).
Use a suitable tool (wooden scraper) to clean out the cylinder space (16), especially
the cooling fins.
Remove the rag from the cylinder port and refit the muffler according to the diagram.
Replace the gasket (13) if necessary. Carefully remove any pieces of the old gasket
from the muffler.
Ensure correct mounting position.
The cowling should follow the contour of the cylinder to ensure correct heat transfer.
Tighten screws (14) to 10 Nm while the engine is cold.
Instructions for periodic maintenance
To ensure long life, prevent damage and ensure the full functioning of the safety features the following maintenance must be performed regularly. Guarantee claims can be rec-
ognized only if this work is performed regularly and properly. Failure to perform the prescribed maintenance work can lead to accidents!
The user of the chain saw must not perform maintenance work which is not described in the instruction manual. All such work must be carried out by a MAKITA service centre.
