CARE AND MAINTENANCE
13. Chain Maintenance
WARNING
• Remove the battery pack before performing any maintenance; failure to heed this warning
could result in serious personal injury.
• Always wear gloves when handling the saw chain; these components are sharp and may
contain burrs.
Use only low-kickback chains on this saw. This fast cutting chain will provide kickback
reduction when properly maintained.
A properly sharpened saw chain cuts through wood effortlessly, even with very little pressure.
Never use a dull or damaged saw chain. A dull saw chain cutter leads to increased physical
strain, increased vibration load, unsatisfactory cutting results and increased wear.
For smooth and fast cutting, the saw schain needs to be maintained properly. The saw chain
requires sharpening when the wood chips are small and powdery, the chain must be forced
through the wood during cutting, or the saw chain will cut to one side. During maintenance of
your saw chain, consider the following:
• Improper filing angle of the side plate can increase the risk of a severe kickback.
• Raker (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.
Sharpen the Cutters
Be careful to file all cutters (Fig. 13a) to the
specified angles and to the same length, as fast
cutting can be obtained only when all cutters are
uniform.
a. Remove the battery pack. Wear gloves for
protection.
b. Properly tension the chain prior to sharpening.
Refer to the section: “
Adjusting the Chain
Tension
” earlier in this manual.
c. Use a 5/32ʺ (4.4 mm) diameter round file and
holder (available separately). Do all of your
filing at the middle position of the guide bar.
d. Keep the file level with the top plate of the tooth. Do not let the file dip or rock.
