Chain sharpening
Sharpen the chain regularly to maintain optimum
performance of the saw. Signs of a dull chain are:
• The sawdust becomes powder-like
• Extra force is required to execute a cut
• The cut does not track in a straight line
• Increased vibration
• Increased fuel consumption
WARNING. Wear heavy
gloves when handling the chain.
Hold the guide bar (1) securely
in a vice.
Sharpen each cutter using
the chain file (30). Always use
outward strokes.
After sharpening, the cutters
must all have the same width
and length. After every 3-4 times use an authourised repair
centre to professionally sharpen your saw chain. They have
the special tools necessary to ensure the correct cutting
angles and depths.
Guide bar wear
Reverse the guide bar every 8 working hours to ensure
uniform wear. Check the bar rails frequently and if
necessary remove burs and square-up the rails using a
flat file.
