least 5 cm outside the outline of the wood
log.
■ Ensure the saw chain is running at full speed
before it makes contact with the wood.
Use the gripping teeth (m1) to secure the
product onto the wood before starting to
cut and use it as a leverage point while
cutting(see figure M).
■ Do not force the saw chain while cutting,
let the chain do the work.
■ Never operate the chain saw with arms
fully extended. Do not attempt to saw areas
which are difficult to reach, or on a ladder.
Never saw above shoulder height.
■ Beware when reaching the end of the
cut. The weight of the chain saw changes
unexpectedly as it cuts free from the wood.
Danger of injury to the legs and feet.
■ Always remove the chain saw from a wood
cut while the saw chain is running.
Felling a tree (see figure N & O)
When bucking and felling operations are
being performed by two or more persons at
the same time, the felling operations should
be separated from the bucking operation by
a distance of at least twice the height of the
tree being felled. Trees should not be felled
in a manner that would endanger any person,
strike any utility line or cause any property
damage. If the tree does make contact with
any utility line, the company should be
notified immediately.
The operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide
downhill after it is felled.
An escape path should be planned and cleared
as necessary before cuts are started. The escape
path should extend back and diagonally to the
rear of the expected line of fall.
Before felling is started, consider the natural
lean of the tree, the location of larger branches
and the wind direction to judge which way the
tree will fall.
Remove dirt, stones, loose bark, nails, staples
and wire from the tree.
Limbing and pruning (see figure P)
Limbing is removing the branches from a fallen
tree. When limbing leave larger lower limbs
to support the log off the ground. Remove the
small limbs in one cut. Branches under tension

should be cut from the bottom up to avoid
binding the product.
Cutting wood under tension (see
figure Q)
WARNING!
Be extremely careful when sawing wood,
branches or trees under tension. Leave saw
jobs like these to trained professionals.
There is a high risk of accidents.
When sawing logs supported on both ends,
start the cut from above (A) about one third of
the diameter into the log and then finish the
cut at the same spot from below (B), in order
to avoid splitting of the log or jamming of the
saw. Avoid contact of the saw chain with the
ground.
When sawing logs supported on only one
end, start the cut from below (A) about one
third of the diameter into the log and then
finish the cut at the same spot from above
(B), in order to avoid splitting of the log or
jamming of the saw.
Bucking a log
■ Follow the simple directions for easy
cutting. When the log is supported along its
entire length, it is cut from the top (overbuck,
see figure R).
■ When the log is supported on one end,
cut 1/3 the diameter from the underside
(underbuck). Then make the finished cut by
overbucking to meet the first cut (see figure
S).
■ When the log is supported on both
ends, cut 1/3 the diameter from the top
(overbuck). Then make the finished cut by
underbucking the lower 2/3 to meet the
first cut (see figure T).
■ When bucking on a slope always stand on
the uphill side of the log. When "cutting
through", to maintain complete control
release the cutting pressure near the end
of the cut without relaxing your grip on
the product handles. Do not let the chain
contact the ground. After completing the
cut, wait for the saw chain to stop before
you move the product. Always switch off
the product before moving from tree to
tree (see figure U).
