Felling Trees
Cutting with the Saw
Always use full throttle while cutting!
Keep the chain sharp and let the saw do
the work! Forcing the saw into the wood
reduces cutting performance, and can
damage the saw through overheating!
Clear a safe work
area before cutting.
Stop the saw before moving it to or
from the work area.
Wear hearing protection and eye protection
such as a face shield or goggles when
operating the unit to shield against saw dust.
Always wear gloves
when operating this saw.
Use full-throttle while
cutting and apply only enough
bar pressure to maintain engine
speeds of 9,000-10,000 min

.
Wear close-fitting
clothing to protect
your legs and arms.
Do not wear clothing
or jewelry that could
get caught in
the machinery
or brush.
Keep a proper footing
(do not overreach)!
Wear
appropriate
non-skid footwear.
NEVER
operate with a
loose saw chain!
NEVER
operate the saw if
fastenings are loose or
missing!
NEVER
operate the saw
if any component parts
are damaged, loose, or
missing!
IMPORTANT!
Always wear leg protection (Chaps)
made of a cut-resistant material such
as ballistic nylon covering the full
length of the thigh to the top of the
boot.
Before Felling a Tree
1. Determine the direction of fall by
inspecting:
Tree shape and angle of lean.
Size and shape/placement of limbs.
Location of nearby trees or other
obstacles.
Condition of tree (damage, disease,
etc.).
Prevailing wind direction.
2. Clear a safe work area around the
tree. Be alert for loose or dead limbs
overhead. Clear an appropriate escape
path approximately 45° from the
direction of fall.
3. Notify nearby workers of your
intentions!

WARNING!
Diseased, damaged, or
otherwise unbalanced trees
can fall unpredictably during felling,
and should be left to an experienced
timber faller!
1. Determine the direction of fall. If
uncertain as to the direction of fall, use
the procedure “Felling Large Trees” as
outlined in the next section.
Bumper
Spike
2. Engage the bumper spike against the
trunk of the tree and start to cut on the
side of the tree away from the fall. Make
a single cut all the way through the tree.
3. When the tree begins to fall, stop the
saw, and put it down on the ground.
4. Use your retreat path to exit the area
quickly.
