12 STARTING AND STOPPING THE CHAIN SAW (FIG. A)
WARNING Keep body to the left of the chain line. Never straddle the saw or

Maintenance of this manual.
▪ Make sure the sprocket cover lock bolt (4) is tight to the chain cover.

contact with the bar and chain. Fit the battery pack (9) into the chain saw.
▪ Depress the lock-off button (6) and pull the trigger switch (5).
▪ Press and hold the trigger switch (5), release the lock-off button (6) and continue to
squeeze the trigger switch (5) for continued operation.

13 CLEANING AND MAINTENANCE
13.1 Guide bar maintenance
Most guide bar problems can be prevented merely by keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the saw with chain that is too tight will contribute
to rapid bar wear. To help minimize bar wear, the following guide bar maintenance procedures
are recommended :
▪ Thoroughly clean the guide bar and the guide groove with a brush and solvent.
▪ Replace the guide bar if the guide groove is damaged or worn and the saw chain has too
much lateral space.
▪ Tighten all accessible screws, if necessary.
Warning: always wear protective gloves during maintenance operations. Do
not carry out maintenance when the engine is hot.
13.2 Chain sharpening
For the inexperienced chain saw user, we recommend that the saw chain be professionally
sharpened by the nearest professional service center. If you feel comfortable sharpening your
own saw chain, special tools are available from the professional service center.
Chain sharpening requires special tools to ensure that cutters are sharpened at the correct angle
and depth.
Warning: when having a wrong sharpened chain, there may occur a higher
danger of kickback.
