Use and Care Manual

•

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 qualied 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

qualied service technician.

How to Sharpen the Cutters

Be careful to le all cutters (Fig. 30) to the

specied 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 le

and holder (available separately). Do all

of your ling at the middle position of the

guide bar.

4. Keep the le level with the top plate of the

tooth. Do not let the le dip or rock.

5. Keep a correct sharpening angle of 30° between the le and the saw chain; see

Fig. 31 & 32. Always use a le holder (available separately) when sharpening saw chains

by hand. File holders have markings for the sharpening angle.
