Cleaning the cylinder space
CAUTION:
• Always wear eye protection.
After long period of operation, dust may accumulate in cylinder space. It may cause
overheating of the engine. Clean the cylinder space occasionally.
Perform cleaning as follows:
1. Open two hooks, and remove the cleaner cover.
2. Remove the air cleaner.
NOTE:
• During cleaning, cover the opening with a clean cloth to prevent dirt or foreign
materials from falling into the carburetor.
3. Remove three screws and remove the cylinder cover. It is easier to remove the
cylinder cover when the front hand guard is forward position.
4. Clean the cylinder space and cylinder fins. Use a brush or air compressor if
necessary.
5. Return the cylinder cover, air cleaner, and cleaner cover after cleaning.
Checking the screws on the muffler
Remove the cylinder cover and dust cover, and check the tightness of four screws
on the muffler. Tighten it if it is loose.
Checking the spark arrester
CAUTION:
• Do not start the engine if the spark arrester is damaged or missing.
The spark arrester prevents hot carbon from flying out of exhaust pipe. Check the
spark arrester regularly as following steps:
1. Remove the cylinder cover.
2. Remove the screw which secures the spark arrester. It is easier to remove the
screw by pushing the front hand guard forwards. Then slide the spark arrester.
Clean the spark arrester if necessary with a wire brush.
If the spark arrester is damaged, replace it.
Cleaning of parts
Always keep the engine clean by wiping down with a cloth rag.
Inspection of bolts, nuts and screws
- Check bolts, nuts, etc. Tighten them if necessary.
- Check the fuel cap and oil cap for tightness. Check for fuel leakage.
- Replace damaged parts with new ones for safety operation.
Storing tool
CAUTION:
• The engine is still hot just after stopping engine. When draining the fuel, allow
sufficient time for the engine to cool down after stopping it. Otherwise a skin burn
and/or fire may result.
• When the machine is kept out of operation for a long time, drain all fuel from the
fuel tank and carburetor, and keep it at a dry and clean place.
Biologically degradable saw chain oil can only be kept for a limited period. Beyond
two years after manufacture, biological oils begin to acquire an adhesive quality,
and cause damage to the oil pump and components in the lubricating system.
- Before taking the chain saw out of service for a longer period, empty the oil tank
and fill it with a small quantity of engine oil (SAE 30).
- Run the chain saw briefly to flush all residue of the biological oil out of the tank,
lubricating system and saw mechanism.
Store the chain saw on a suitable surface.
Before returning the chain saw to service, fill up with fresh bio-degradable saw
chain oil.
NOTE:
• When the chain saw is taken out of service, small quantities of chain oil leaks
from it for some time afterwards. This is normal, and is not a sign of a fault.
