• It is easier to saw a log using the spiked bumper
(Fig. 28D).
– Dig the spiked bumper into the log and use it as a
pivot. Cut with an arched motion to make the bar
penetrate the wood.
– Repeat several times if necessary, changing the point
where you plant the spiked bumper.

– 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.

WARNING!
Always unplug the power cord before
performing any adjustments, maintenance, or repairs to your
electric pole + chain saw.
• Use protective gloves when handling the bar and chain.
• Keep the bar encased in its sheath, except when working
directly on the bar or the chain.
• Never dispose of oils or other polluting materials in
unauthorized places.

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).
