INSTRUCTIONS CONCERNING THE PROPER
TECHNIQUES FOR BASIC LIMBING AND CROSS-
CUTTING
UNDERSTANDING THE FORCES WITHIN THE WOOD
When you understand the directional pressures and
stresses inside the wood, you can reduce the pinches or at
least expect them during your cutting. Tension in the wood
means the bres are being pulled apart, and if you cut in this
area, the kerf or cut tends to open as the saw goes through.
If a log is being supported on a saw-horse and the end is
hanging unsupported over the end, tension is created on
the upper surface due to the weight of the overhanging log
stretching the bres. Likewise, the underside of the log is
compressed and the bres are being pushed together. If a
cut is made in this area, the kerf tends to close up during the
cut. This cut would pinch the blade.
PUSH AND PULL
The reaction force is always opposite to the direction the
chain is moving. The operator must be ready to control the
tendency for the product to pull away and push backwards.
The product pulls away (forward motion) when cutting on
the bottom edge of the bar. The product pushes backwards
(towards the operator) when cutting along the top edge.
SAW JAMMED IN THE CUT
Turn o the product, and remove the battery pack. Do not
try to force the chain and bar out of the cut as this is likely
to break the chain, which may swing back and strike the
operator. This situation normally occurs because the wood
is incorrectly supported, which forces the cut to close under
compression, thereby pinching the blade. If adjusting the
support does not release the bar and chain, use wooden
wedges or a lever to open the cut and release the saw.
Never try to start the pruning saw when the guide bar is
already in a cut or kerf.
SKATING/BOUNCING
When the pruning saw fails to dig in during a cut, the guide
bar can begin hopping or dangerously skidding along the
surface of the log or branch, possibly resulting in the loss of
control of the pruning saw. To prevent or reduce skating or
bouncing, always use the saw with both hands. Make sure
that the saw chain establishes a groove for cutting.
Never cut small, exible branches or brushes with your
pruning saw. Their size and exibility can easily cause the
saw to bounce towards you or bind up with enough force
to cause a kickback. The best tool for that kind of work is
a hand saw, pruning shears, an axe, or other hand tools.
BUCKING A LOG
Bucking is cutting a log into lengths. It is important to make
sure your footing is rm and your weight is evenly distributed
on both feet. When possible, the log should be raised and
supported by the use of limbs, logs or chocks. Follow the
simple directions for easy cutting. When the log is supported
along its entire length, it is cut from the top (overbuck).
When the log is supported on one end, cut 1/3 the diameter
from the underside (underbuck). Then make the nished cut
by overbucking to meet the rst cut.

When bucking on a slope always stand on the uphill side of
the log. To maintain control when “cutting through”, release
the cutting pressure near the end of the cut without relaxing
your grip on the pruning 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 pruning saw. Always stop
the motor before moving from tree to tree.
LIMBING A TREE
Limbing is removing the branches from a fallen tree. When
limbing, leave larger lower limbs to support the log o the
ground. Remove the small limbs in one cut. Branches under
tension should be cut from the bottom up to avoid binding
the pruning saw.
SPRINGPOLES
A springpole is any log, branch, rooted stump, or sapling
that is bent under tension by other wood so that it springs
back if the wood holding it is cut or removed.
On a fallen tree, a rooted stump has a high potential of
springing back to the upright position during the bucking
cut to separate the log from the stump. Watch out for
springpoles—they are dangerous. Do not attempt to cut
bent branches or stumps that are under tension unless you
are professionally trained and competent to do so.
