9. MAINTENCE OF SAW CHAIN AND GUIDE BAR
It is very important for smooth and safe operation to
keep the cutters always sharp.
a. Your cutters need to be sharpened when:
Sawdust becomes powdery/fine.
You need extra force to saw in.
The cut line does not go straight.
Vibration increases.
Fuel consumption increases.
b. Cutter setting standards:
Make sure the saw chain is held securely.
Make sure the engine is stopped.
Use a round file of proper size for your chain.
Place your file on the cutter and push straight forward.
Keep the file position as illustrated. After every cutter has been set, check the
depth gauge and file it to the proper level as illustrated.
Be sure to round off the front edge to reduce the
chance of kickback or tie-strap breakage.
