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. The chain is 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 chain needs to be maintained properly. 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 are the indicators that the chain requires sharpening. During
maintenance of your saw chain, consider the following:
• Improper ling 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 qualied 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 qualied service
technician.
Sharpen the Cutters
Be sure to le all cutters (Fig. 13a) to the specied
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 le and
holder (available separately). Do all of your
ling at the middle position of the guide bar.
d. Keep the le level with the top plate of the
tooth. Do not let the le dip or rock.
