For smooth and fast cutting, the chain needs to be maintained properly. The chain
requires sharpening when the wood chips are small and powdery, the chain must
be forced through the wood during cutting, or the chain cuts to one side. During
maintenance of your chain, consider the following:
◾
Improper filing angle of the side plate can increase the risk of a severe kickback.
◾
Depth gauge clearance. Too low increases the potential for kickback. Not low enough
decreases cutting ability.
◾
If cutter teeth have hit hard objects, such as nails and stones, or have been abraded by
mud or sand on the wood, have the chain sharpened by a qualified service technician.
NOTICE:
Inspect the drive sprocket for wear or damage when replacing the chain. If
signs of wear or damage are present in the areas indicated, have the drive sprocket
replaced by qualified service technician.
How to Sharpen the Cutters
Be careful to file all cutters (Fig. 31) to the
specified angles and to the same length,
as fast cutting can be obtained only when
all cutters are uniform.
1. Remove the battery pack. Wear
gloves for protection.
2. Make sure that the chain is
properly mounted and the quick
chain-tension adjust knob is fully
tightened, which ensures that the chain is correctly tensioned.
3. Use a 5/32" (4.0 mm) diameter round file and holder (available separately). Do all
of your filing at the middle position of the guide bar for perfect balance.
4. Keep the file level with the top plate of the tooth. Do not let the file dip or rock.
