Maintaining the Guide Bar
1. Remove any sawdust from the guide bar, including the groove. Oil and sawdust combine and emit a
burning smell during operation if the guide bar is not regularly cleaned.
2. Make sure that the oil port is not clogged. Grease the
nose sprocket at the tip of the guide bar.
3. Check for oil leakage and loose fastenings, especially
those securing the handles and the guide bar.
4. Reverse the guide bar every 8 working hours to ensure
uniform wear. Check the guide rails frequently and if
necessary remove burrs and square up the rails using
a flat file.
WARNING!
ALWAYS WEAR GLOVE WHEN HANDLING THE CHAIN AS
IT IS VERY SHARP AND CAN CUT YOU WHEN IT IS NOT MOVING.
Chain Sharpening
Chain File: 4.0mm (5/32”)
Chain Pitch: 9.52mm (3/8” LP)
Chain Gauge: 1.10mm (0.043”)
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
Sharpen each cutter using a round 4.0mm (5/32”) chain
file. Keep the file level with the top plate of the tooth. Always use outward strokes and maintain a
30° angle between the chain and file. After sharpening, the cutters must all have the same width and
length.
After every 3–4 uses get an authorised repair centre to professionally sharpen your chain. They have
the special tools necessary to ensure the correct cutting angles and depths.
