WORK AREA PRECAUTIONS
See Figure 22.
Cut only wood or materials made from wood
■
Never allow children to operate the saw. Do not Allow
■
persons to use this chainsaw who have not read this
operator's manual or received adequate instructions
for the safe and proper use of this chainsaw.
Keep helpers, bystanders, children, and animals,
■
a SAFE DISTANCE from the cutting area. During
felling operations, the safe distance should be a least
twice the height of the largest trees in the felling area.
During bucking operations, keep a minimum distance
of 5 metres between workers.
Always cut with both feet on solid ground to prevent
■
being pulled off balance.
Do not cut above chest height as a saw held higher is
■
difficult to control against kickback forces.
Do not fell trees near electrical wires or buildings.
■
Leave this operation for professionals.
Cut only when visibility and light are adequate for you
■
to see clearly.
BASIC OPERATING/CUTTING
PROCEDURES
Practice cutting a few small logs using the following
technique to get the "feel" of using the saw before you
begin a major sawing operation.
Take the proper stance in front of the wood with the
■
saw idling.
Accelerate the engine to full throttle just before
■
entering the cut by squeezing the throttle trigger.
Begin cutting with the saw against the log.
■
Keep the engine at full throttle the entire time you are
■
cutting.
Allow the chain to cut for you; exert only light
■
downward pressure. Forcing the cut could result in
damage to the bar, chain, or engine.
Release the throttle trigger as soon as the cut is
■
completed allowing the engine to idle. Running the
saw at full throttle without a cutting load can result in
unnecessary wear to the chain, bar, and engine.
Do not put pressure on the saw at the end of the
■
cut as this may cause the saw to drop in an unsafe
manner.
OPERATION
FELLING TREES IN HAZARDOUS CONDITIONS
WARNING:
Do not fell trees during periods of high wind or
heavy rain. Wait until the hazardous weather
has ended. When felling a tree, it is important
that you heed the following warnings to prevent
possible serious injury.
Do not cut down trees having extreme lean or large
■
trees with rotten limbs, loose bark, or hollow trunks.
Have these trees pushed or dragged down with heavy

equipment, then cut them up.
Do not cut trees near electrical wires or buildings.
Check the tree for damaged or dead branches that
could fall and hit you during felling.
Periodically glance at the top of the tree during the
back cut to assure the tree is going to fall in the
desired direction.
If the tree starts to fall in the wrong direction, or if the
saw gets caught or hung up during the fall, leave the
saw and save yourself!
Pick your escape route (or routes in case the intended
route is blocked). Clear the immediate area around
the tree and make sure there are no obstructions in
your planned path of retreat. Clear the path of safe
retreat approximately 135° from the planned line of
fall.
Consider the force and direction of the wind, the lean
and balance of the tree, and the location of large
limbs. These things influence the direction in which
the tree will fall. Do not try to fell a tree along a line
different from its natural line of fall.
Cut a notch about 1/3 the diameter of the trunk in the
side of the tree. Make the notch cuts so they intersect
at a right angle to the line of fall. This notch should be
cleaned out to leave a straight line. To keep the weight
of the wood off the saw, always make the lower cut of
the notch before the upper cut.
Make the back cut level and horizontal, and at a
minimum of 2 in. above the horizontal cut of the notch.
Note: Never cut through to the notch. Always leave
a band of wood between the notch and back cut
(approximately 2 in. or 1/10 the diameter of the tree).
This is called a "hinge" or "hinge wood." It controls
the fall of the tree and prevents slipping or twisting or
shoot back of the tree off the stump.
On large diameter trees, stop the back cut before
it is deep enough for the tree to either fall or settle
back on the stump. Then insert soft wooden or plastic
wedges into the cut so they do not touch the chain.
Drive wedges in, little by little, to help jack the tree
over.
As tree starts to fall, stop the chainsaw and put it
down immediately. Retreat along the cleared path, but
watch the action in case something falls your way.
WARNING:
Never cut through to the notch when making a
back cut. The hinge controls the fall of the tree,
this is the section of wood between the notch
and back cut.
