SHARPENING
• Switch off the engine before sharpening the saw chain.
• Always wear gloves when working on saw chain.
• It is important to file the saw chain to the correct depth and angle. Improper lowering or sharp-
ening of the depth gauges may increase the risk of kickback injury.
Sharpening
The saw chain should be sharpened once a day.
1. Lock the chain.
2. The saw chain have alternative left and right hand
cutters. Always sharpen from the inside out.
3. Keep the file to the angle lines of the top plate angle.
4. Hold the file horizontally.
Depth gauge adjustment
The depth control determines the thickness of wood chip
produced and must be maintained correctly throughout the
chain life.
As the cutter length is reduced, the depth control height is
altered and must be reduced.
1. Position the depth gauge, and file off any of the depth
control which protrudes.
2. Round off the front of the depth control to allow smooth
cutting.
3. Keep the Lower edge of the drive link sharp. (Drive link
serves to remove sawdust from the groove of the guide
bar.)

driver or a wire.

• Check sprocket and the clutch.
• Clean the bar mount area before installation of the guide
bar.
