• Press the ON button to turn unit on, press
the safety lock and squeeze the trigger
switch then release the safety lock and let
the chain accelerate to full speed before
entering the cut.
• Begin cutting with the saw against the log.
• Keep the unit running the entire time you
are cutting, maintain a steady speed.
• Allow the chain to cut for you; exert only
light downward pressure. Forcing the cut
could result in damage to the bar, chain, or
motor.
• Release the trigger switch as soon as the
cut is completed, allowing the chain to
stop. If you run the saw without a cutting
load, unnecessary wear can occur to the
chain, bar, and unit.
• Do not put pressure on the saw at the end
of the cut.

WORK AREA PRECAUTIONS
• Cut only wood or materials made from
wood; no sheet metal, no plastics, no
masonry, no nonwood building materials.
• Never allow children to operate the saw.
Allow no person to use this chainsaw
who has not read this operator's manual
or received adequate instructions for the
safe and proper use of this chainsaw.
• Keep everyone – helpers, bystanders,
children, and animals – a SAFE
DISTANCE from the cutting area. During
felling operations, the safe distance
should be at least twice the height of the
largest trees in the felling area. During
bucking operations, keep a minimum
distance of 15 ft. (4.6 m) 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.

FELLING TREES
HAZARDOUS CONDITIONS
WARNING:
periods of high wind or heavy precipitation.
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 an 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 backcut 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.
REMOVING BUTTRESS ROOTS
A buttress root is a large root extending
from the trunk of the tree above the ground.
Remove large buttress roots prior to felling.
Make the horizontal cut into the buttress
first, followed by the vertical cut. Remove the
resulting loose section from the work area.
Follow the correct tree felling procedure as
stated in Proper Procedure For Tree Felling
after you have removed the large buttress
roots.
