13.2 Sawing
WARNING
■ If kickback occurs, the chainsaw can be
thrown up in the direction of the operator. This
may result in serious or fatal injury to the user.
► Always cut with the chain running at full
speed.
► Do not cut with the upper quadrant of the
guide bar nose.
► Begin the cut with the chain running at full
speed and keep the guide bar vertical.
► Engage the spiked bumper and use it as a ful‐
crum.
► Guide the full width of the guide bar into the
wood and reposition the spiked bumper as
required.
► Pick up the weight of the chainsaw at the end
of the cut.
The chainsaw is standard equipped without the
spiked bumper. STIHL recommends retrofitting
with a spike bumper for working on resistant
wood so that the chainsaw can be positioned
safely.
13.3 Limbing
► With the chain running a full speed, pivot the
guide bar downward against the limb.

damaging the bark.

right angles to the direction of fall.
► Make the horizontal cut.
► Make the angle cut at 45° to the horizontal cut.
