– When bucking on a slope, always stand on the uphill
side of the log. When cutting through the log,
maintain control by releasing the cutting pressure
near the end of the cut without relaxing your grip on
the chain saw handles. Do not let the chain contact
the ground.
After completing the cut, wait for the saw chain to stop before
you move the chain saw. Always stop the motor before moving
from tree to tree.

Motor Cooling
To avoid overheating and damage to the motor, always keep
the cooling air vents clean and free of sawdust and debris.
Chain Tension
Check the chain tension before using the saw when the chain
is cold. The correct tension of a cold chain is when there is no
slack on the underside of the guide bar; the chain is snug, but
you can rotate it by hand without binding.
During normal saw operation, the temperature of the chain will
increase. The drive links of a correctly tensioned warm chain
will hang approximately 0.050 in. (1.25 mm) out of the bar
groove (Fig. 29). Be aware that a chain tensioned while warm,
may be too tight upon cooling. Check the "cold tension"
before next use. The chain must be re-tensioned whenever the
flats on the drive links hang out of the bar groove (Fig. 29).

Chain Sharpening
m
WARNING!
To ensure that the saw works safely and
efficiently, it is essential that the cutting components are
well-sharpened. It is highly recommended to replace the
chain once it loses its ability to cut cleanly and safely.
It is possible, however, to sharpen the existing chain if the
sharpening is carefully performed. Any work on the chain and
bar requires specific experience and special tools. For safety
purposes, we recommend you contact an authorized

Sharpening is necessary when:
• The sawdust looks like dust;
• Cutting becomes more difficult;
• The cut is not straight;
• Vibrations increase.
