5. Install new guide bar and saw chain, following the section: "ASSEMBLING THE GUIDE
BAR AND CHAIN".
NOTICE
This is a good time to inspect the drive sprocket for excessive wear or damage.
CHAIN MAINTENANCE
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 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 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.
Inspect the drive sprocket for wear or damage when replacing the chain. If signs
NOTICE
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. 9) 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. Properly tension the chain prior to
sharpening. Refer to the section:
"ADJUSTING THE CHAIN TENSION"
earlier in this manual.
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.
4. Keep the file level with the top plate of the tooth. Do not let the file dip or rock.
5. Keep the correct sharpening angle of 30° between the file and the saw chain (see Fig. 10
and Fig. 11). Always use a file holder (available separately) when sharpening saw chains
by hand. File holders have markings for the sharpening angle.
6. Using light but firm pressure, perform a stroke towards the front corner of the tooth. Lift the
file away from the steel on each return stroke.
