4. Use a soft wire brush to clean up and carbon build up on spark plug

Chain Sharpening
WARNING: Always ensure the engine is turned off before
undertaking this task.
Sharpen the chain regularly to maintain optimum performance of the
chainsaw.
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 (18) securely in a vice.
Sharpen each cutter using the supplied sharpening file (33). Always use
outward strokes. (Fig AJ)
After sharpening, the cutters must all have the
same width and length. After every 3 - 4 times use
a repair centre to professionally sharpen your saw
chain. They have the special tools necessary to
ensure the correct cutting angles and depths
are even.
Guide Bar Wear
Reverse the guide bar (18) every 8 working hours to ensure uniform wear.
Check the bar rails frequently and if necessary remove burrs and square-up
the rails using a flat file.
