ADJUST THE CHAIN TENSION
IMPROPERLY TENSIONED SAW CHAINS CAN
BECOME DETACHED FROM THE GUIDE BAR,
POSING A SIGNIFICANT RISK OF SERIOUS
INJURY OR DEATH.
A saw chain becomes longer when you use it. It is
essential to regularly adjust the tension of the saw
chain. Remember to inspect the saw chain tension
every time you refill the chain oil.
Note: During the initial period of using a new saw
chain, it goes through a run-in phase. It is important to
check the tension of the chain more frequently during
this time.
WEAR PROTECTIVE GLOVES IF YOU TOUCH
THE CHAIN, BAR, OR AREAS AROUND THE
CHAIN.
1.
Switch off the chainsaw and engage the chain
brake.
2.

Note: It is not necessary to remove the sprocket cover
to adjust the chain tension.

tensioning screw clockwise to tighten the chain,
or counterclockwise to loosen it.

SAW CHAIN MAINTENANCE
Sharpen the cutters
If the chain does not easily penetrate the wood, it is
necessary to sharpen the cutters.
Note: For important sharpening work, we recommend
taking the chainsaw to a service center equipped with
an electric sharpener.
1.
If sharpening by hand, use a round gauge file
with holder to sharpen the cutting teeth.
2.
Apply the holder correctly onto the cutter.
3.
Move the file from the inner side of the cutting
teeth and out. Decrease the pressure on the pull
stroke.
4.
Remove material from one side of all the cutting
teeth.
