MAINTENANCE (cont.)
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.
Chain Sharpening
Chain File: 4.0mm (5/32”)
Chain Pitch: 9.52mm (3/8” LP)
Chain Gauge: 1.27mm (0.050”)
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.
WARNING!
ALWAYS WEAR GLOVES WHEN HANDLING THE CHAIN AS IT
IS VERY SHARP AND CAN CUT YOU WHEN IT IS NOT MOVING.
