AIR FILTER
- Remove and wash the filter in a non-flammable detergent such as hot soapy
water and dry (fig.21).
- Check the air filter for damage and deformation. Replace the filter if damaged.
- Install the air filter and refit the cover using the screw.
Air filter must be cleaned to remove dust and dirt. A dirty air filter can cause carburetor malfunc-
tions, starting problems, engine power reduction, wear and tear on engine parts and abnormal
fuel consumption.
- Unscrew the screw holding the air filter cover in place and remove the cover (fig. 20).
- Pull the choke lever out to close it. This prevents dirt from entering the carburetor throat
when the air filter is removed.
- Brush the accumulated dirt and dust from the air cleaner area before removing the air
cleaner.
SPARK PLUG
The condition of the spark plug is influenced by an incorrect carburetor setting,
too much oil in the fuel mixture, a dirty air cleaner and hard running conditions such as cold
weather. These factors can cause deposits to build up on the electrodes which may result in
malfunctions and starting problems. If the engine is low on power, difficult to start or runs poorly
at idle speed, always check the spark plug first.
To check and re-gap spark plug, remove the air filter cover, remove spark plug lead
and
remove spark plug using the T-wrench (fig.22). Clean the electrodes with a fine wire
brush.
Re-gap spark plug using feeler gauge.
Gap is 0.6mm
Replace spark plug if electrode is
worn.
Use replacement plug NGK # BPMR7A or Champion # RCJ6Y.
Install spark plug, torque
to 11-14 ft.lbs., attach spark plug lead and refit air filter cover.
GUIDE BAR AND OIL HOLES
Clean guide bar before use. Follow instructions for removing and installing guide bar and saw
chain. Remove guide bar and clean groove of the guide bar with a small screwdriver. Clean oil
holes with a wire (fig.23). Check the sprocket and the clutch and clean the bar mount area
before installing the bar. Guide bar with sprocket nose should be lubricated with grease using a
lubricating syringe. Invert the symmetrically shaped guide bar every 8 working hours or each
time the chain is removed to ensure uniform wear. Check the bar rails frequently for wear and
remove burrs and square up the rails using a flat file. Clean the Oiler port on the saw every time
the saw chain and guide bar are removed.
WARNING
When installing the air filter, make sure it is secure before refitting the cover.
