GENERAL SAFETY RULES
• Do not overreach or cut above chest height.
• Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
• Only use replacement bars and chains spec-
ified by the manufacturer or the equivalent.
WARNING:
Read and understand all instructions. Failure
to follow all instructions listed below, may result
in electric shock, fire and/or serious personal
injury.
Do not operate a chain saw with one hand.
Serious injury to the operator, helpers, bystand-
ers, or any combination of these persons may
result from one-handed operation. A chain saw
is intended for two-handed use.
Do not operate a chain saw when you are
fatigued. Fatigue causes carelessness. Never
operate a chain saw when you are tired or under
the influence of medication, drugs, or alcohol.
Use safety footwear. Wear snug-fitting cloth-
ing, protective gloves, and eye, hearing, and
head protection devices.
Heavyprotectiveclothingmayincreaseoper-
ator fatigue, which could lead to heat stroke.
During weather that is hot and humid, heavy
work should be scheduled for early morning
or late afternoon hours when temperatures are
cooler.
Do not stand on any unstable surface while
using the chain saw, such as ladders, scaffolds,
trees, etc.
Use caution when handling fuel. Move the
chain saw at least 30 feet from the fueling point
before starting the engine.
Do not allow other persons to be near the
chain saw when starting or cutting with the
chain saw. Keep bystanders and animals out
of the work area.
Do not start cutting until you have a clear
work area, secure footing, and a planned retreat
path from the falling tree.
READ ALL INSTRUCTIONS
Know your tool. Read the operator’s manual
carefully. Learn the saw’s applications and lim-
itations as well as the specific potential hazards
related to this tool.
Kickback may occur when the nose or tip of
the guide bar touches an object, or when the
wood closes in and pinches the saw chain in
the cut. Tip contact in some cases may cause a
lightning-fast reverse reaction, kicking the guide
bar up and back toward the operator. Pinching
the saw chain along the top of the guide bar
may push the guide bar rapidly back toward the
operator. Either of these reactions may cause
you to lose control of the saw, which could result
in serious personal injury. Do not rely exclusively
upon the safety devices built into the saw. As a
chain saw user, you should take several steps
to keep your cutting jobs free from accident or
injury.
• With a basic understanding of kickback,
you can reduce or eliminate the element
of surprise. Sudden surprise contributes to
accidents.
• Keep a good firm grip on the saw with both
hands when the engine is running. Place your
right hand on the rear handle and your left
hand on the front handle with your thumbs
and fingers encircling the chain saw handles.
A firm grip together with a stiff left arm will
help you maintain control of the saw if kick-
back occurs.
Keep all parts of your body away from the
saw chain when the engine is running.
Always carry the chain saw with the engine
stopped and the brake engaged, the guide bar
and saw chain to the rear, and the muffler away
from your body. When transporting the chain
saw, use the appropriate guide bar scabbard.
• Make sure that the area in which you are
cutting is free from obstructions. DO NOT
let the nose of the guide bar contact a log,
branch, fence, or any other obstruction that
could be hit while you are operating the saw.
• Cut at high engine speeds. Always cut
with the engine running at full speed. Fully
squeeze the throttle trigger and maintain a
steady cutting speed.

securely assembled. Be sure that the saw chain
stops moving when the throttle control trigger
is released.
listed in the instruction manual and all main-
tenance, should be performed by competent
chain saw service personnel. (For example, if
improper tools are used to remove the flywheel
or if an improper tool is used to hold the flywheel
in order to remove the clutch, structural damage
to the flywheel could occur and subsequently
could cause the flywheel to burst.)
Shut off the engine before setting the chain
saw down. Do not leave the engine running
unattended. As an additional safety precaution,
apply the chain brake prior to setting down the
saw.
Use extreme caution when cutting small-size
brush and saplings because slender material
may catch the saw chain and be whipped
toward you or pull you off balance.
When cutting a limb that is under tension,
be alert for springback so that you will not be
struck when the tension in the wood fibers is
released.
Always have a fire extinguisher available
when using chain saw.
Use only the replacement guide bars and low
kickback chains specified for the saw.
Do not adapt the powerhead to a bow guide
or use it to power any attachments or devices
not listed for the saw.
The gas powered saw (or electrically pow-
ered saw) is classified by CSA as a Class 1C
(or Class 2C) saw. It is intended for infrequent
use by homeowners, cottagers, and campers,
and for such general applications as clearing,
pruning, cutting firewood, etc. It is not intended
for prolonged use. Prolonged periods of opera-
tion can cause circulatory problems in the user’s
hands due to vibration.
Keep the handles dry, clean, and free of oil or
fuel mixture.
Do not start or operate the engine in a con-
fined space, building, near open windows,
or in other unventilated space where dan-
gerous carbon monoxide fumes can collect.
Carbon monoxide, a colorless, odorless,
and extremely dangerous gas, can cause Save these instructions. Refer to them

frequently and use to instruct other users. If
you loan someone this tool, loan them these
instructions also.
Do not operate a chain saw in a tree unless
you have been specifically trained to do so.
Do not cut from a ladder; this is extremely
dangerous.
SPECIFIC SAFETY RULES
away from the muffler. Serious burns may occur
if contact is made with the muffler.
Always hold the chain saw with both hands
when the engine is running. Use a firm grip
with thumbs and fingers encircling the chain
saw handles.
Never let anyone use the chain saw who
has not received adequate instructions in its
proper use. This applies to rentals as well as
privately owned saws.
WARNING:
The warnings, labels, and instructions found
in this section of the operator’s manual are for
your safety. Failure to follow all instructions may
result in serious personal injury.
Do not cut vines and/or small underbrush (a
diameter of less than 3 in.).
Muffler surfaces are very hot during and after
operation of the chain saw; keep all body parts
Before you start the engine, make sure the
saw chain is not contacting any object.

and to keep fuel from escaping around the cap.
Tighten the fuel cap securely after refueling.
Wipe spilled fuel from the unit. Move 30 feet
away from refueling site before starting engine.
Keep SAFE-T-TIP™ anti-kickback nose guard
properly mounted on the guide bar to prevent
rotational kickback.
Never attempt to burn off spilled fuel under
any circumstances.
KICKBACK
Follow the sharpening and maintenance
instructions for the saw chain.
Kickback is a dangerous reaction that can
lead to serious injury. Do not rely only on the
safety devices provided with the saw. As a
chain saw user, you must take special safety
precautions to help keep your cutting jobs free
from accident or injury. See the General Safety
Rules and Operation sections of this manual
for added information on kickback and how to
avoid serious personal injury.
CAUTION: User not to use a replacement saw
chain unless it has been designated as meet-
ing the kickback performance requirements in
ANSI/OPEI B175.1-2012 on that specific power
head, or has been designated as low-kickback
replacement saw chain in accordance with
ANSI/OPEI B175.1-2012
Never operate a chain saw that is damaged,
improperly adjusted, or is not completely
and securely assembled. Be sure that the saw
chain stops moving when the throttle control
trigger is released. If the saw chain moves at
idle speed, the carburetor may need adjusting.
Refer to Adjusting the Carburetor in the Main-
tenance section of this manual. If the saw chain
still moves at idle speed after adjustment has
been made, contact a qualified service center
for adjustment and discontinue use until the
repair is made.

ure to heed this warning can result in possible
personal injury.
BAR AND CHAIN LUBRICATION
INCREASE
See Figure 3.
The bar and chain require continuous lubrication.
Lubrication is provided by the automatic oiler
system when the oil tank is kept filled. Lack of
lubricant will quickly ruin the bar and chain. Too
little lubricant will cause overheating shown by
smoke coming from the chain and/or discolor-
ation of the bar. Lubrication can be increased or
decreased by turning (up to 1/4 turn maximum)
the adjustment screw located on the bottom of
the crankcase with the screwdriver end of the
included combination wrench.

ADDING BAR AND CHAIN LUBRICANT
WARNING:
See Figure 3.
Use a bar and chain lubricant designed for lubri-
cating chain saw chains. They are formulated to
extend bar and chain life by protecting against
wear and reducing friction and heat. Chain saw
should use approximately one tank of lubricant
per tank of fuel.
NEVER adjust the automatic oiler system when
the engine is running. Failure to do so could
cause serious personal injury.

IDLE SPEED
SCREW “T”
WARNING:
The chain will move around the guide bar when
adjusting the idle speed. Wear all protective
clothing and keep all bystanders, children, and
pets at least 50 ft. away. Make adjustments
with the unit supported on a stable surface so
that the chain/guide bar does not contact the
ground or any object. Keep all parts of your
body away from the chain/guide bar and muf-
fler. Failure to follow these instructions could
result in serious personal injury.
STOP
If the engine starts, runs, and accelerates,
but will not idle, turn the idle speed screw “T”
clockwise to increase idle speed.

If the chain turns at idle, turn the idle speed
screw “T” counterclockwise to reduce the
idle RPM and stop the chain movement. If the
saw chain still moves at idle speed, contact
a qualified service center for adjustment and
discontinue use until the repair is made.
Page 16 — English
OPERATION
WARNING:
THE SAW CHAIN SHOULD NEVER TURN AT
IDLE. Turn the idle speed screw “T” counter-
clockwise to reduce the idle RPM and stop the
chain, or contact a qualified service center for
adjustment and discontinue use until the repair
is made. Serious personal injury may result from
the saw chain turning at idle.
PULL
PULL AND PUSH
See Figure 14.
The reaction force of the saw is always opposite to
thedirectionthechainismoving.Thus,theoperator
must be ready to control the PULL when cutting
on the bottom edge of the bar and the PUSH when
cutting along the top edge.
NOTE: Thechainsawhasbeenfullyfactorytested.
It is normal to find some slight lubricant residue
on the saw.
WARNING:
KICKBACK occurs when the moving chain
contacts an object at the upper portion of the
tip of the guide bar or when the wood closes in
and pinches the saw chain in the cut. Contact
at the upper portion of the tip of the guide bar
can cause the chain to dig into the object and
stop the chain for an instant. The result is a
lightning-fast reverse reaction which kicks the
guide bar up and back toward the operator. If
the saw chain is pinched along the top of the
guide bar, the guide bar can be driven rapidly
back toward the operator. Either of these reac-
tions can cause loss of saw control, which can
result in serious injury.

PREPARING FOR CUTTING
PROPER GRIP ON HANDLES
See Figure 17.
See General Safety Rules for appropriate safety
equipment.
Wear non-slip gloves for maximum grip and
protection.
Hold the saw firmly with both hands. Always
keep your left hand on the front handle and your
right hand on the rear handle so that your body
is to the left of the chain line.
Fig. 16
WARNING:
Never use a left-handed (cross-handed) grip or
any stance that would place your body or arm
across the chain line.
Maintain a proper grip on the saw whenever the
engine is running. The fingers should encircle
the handle and the thumb is wrapped under the
handlebar. This grip is least likely to be broken
by a kickback or other sudden reaction of the
saw. Any grip in which the thumb and fingers
are on the same side of the handle is dangerous
because a slight kick of the saw can cause loss
of control.

WARNING:
Cut only wood or materials made from wood;
no sheet metal, no plastics, no masonry, no
non-wood building materials.
DO NOT operate the throttle trigger with your
left hand and hold the front handle with your
right hand. Never allow any part of your body
to be in the chain line while operating a saw.
Never allow children to operate the saw. Allow
no person to use this chain saw who has not
read this operator’s manual or received ade-
quate instructions for the safe and proper use
of this chain saw.
STRAIGHT
CHAIN LINE
Keep everyone – 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 15 feet
between workers.

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.

WARNING:
HINGE
Closely check for broken or dead branches,
which could fall while cutting and do not cut
near buildings or electrical wires if you do not
know the direction of tree fall. Do not cut at
night or during bad weather conditions, such as
rain, snow, or strong winds, which can reduce
visibility and control of the chain saw. If the tree
you are felling makes contact with any utility
line, you should discontinue use of the chain
saw and immediately notify the utility company.
Failure to follow these instructions could result
in death or serious personal injury.
BACK CUT
Fig. 22
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.
WEDGE
Fig. 23
your planned path of retreat. Clear paths of safe
retreat should extend back and diagonally (45°)
to the rear of the planned line of fall. When the
tree begins to fall, you should retreat away from
the direction of fall along a retreat path and at
least 20 feet away from the trunk in case it kicks
back over the stump. See Figure 20.
Do not cut trees near electrical wires or build-
ings.
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.
Before felling is started, 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.
The chain saw operator should keep on the
uphill side of the terrain as the tree is likely to
roll or slide downhill after it is felled.
Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where felling cuts are to
be made.
Notched Undercut. Cut a notch about 1/3 the
diameter of the tree as shown in figure 21. Make
the cuts of the notch 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
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!
Felling a tree – When bucking and felling oper-
ations are being performed by two or more
persons, at the same time, the felling operation
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
utility company should be notified immediately.
Before any cuts are started, 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

See Figure 21.
Felling Backcut. The backcut is always made
level and horizontal, and at a minimum of 2 in.
above the horizontal cut of the notch. See Figures
21 - 22.
VERTICAL
CUT
Never cut through to the notch. Always leave a
band of wood between the notch and backcut
(approximately 2 in. or 1/10 the diameter of the
tree). This is called “hinge” or “hingewood.” It
controls the fall of the tree and prevents slipping
or twisting or shoot-back of the tree off the
stump. See Figures 21 - 22.
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. The wedges can
be driven in, little by little, to help jack the tree
over. See Figure 23.

KICKBACK
NOTE: When bucking or felling with a wedge, it
may be necessary to remove the SAFE-T-TIP™
anti-kickback nose guard to allow the bar to be
drawn through the cut. After the cut is complete,
the tip should be reinstalled immediately.
As tree starts to fall, stop the chain saw and put
it down immediately. Retreat along the cleared
path, but watch the action in case something
falls your way. Be alert for overhead limbs or
branches that may fall and watch your footing.

WARNING:
Never cut through to the notch when making a
backcut. The hinge controls the fall of the tree,
this is the section of wood between the notch
and backcut.
REMOVING BUTTRESS ROOTS
See Figure 24.
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
workarea.Followthecorrecttreefellingprocedure
as stated in Felling Trees after you have removed
the large buttress roots.

BUCKING
See Figure 25.
Bucking is the term used for cutting a fallen tree
to the desired log length.
WEDGE
Cut only one log at a time.
Support small logs on a saw horse or another
log while bucking.
Keep a clear cutting area. Make sure that no
objects can contact the guide bar nose and
chain during cutting, this can cause kickback.
To avoid the danger, keep the SAFE-T-TIP™
anti-kickback device attached while cutting.
Refer to Kickback in the Specific Safety Rules
section of this manual for more information.
Fig. 26
LOG SUPPORTED AT ONE END
When bucking on a slope, always stand on the
uphill side of the log. To maintain complete
control of the chain saw when cutting through
the log, release the cutting pressure near the
end of the cut without relaxing your grip on the
chain 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 chain
saw. Always stop the motor before moving from
tree to tree.

BUCKING LOGS UNDER STRESS
See Figure 27.
Make the first bucking cut 1/3 of the way through
the log and finish with a 2/3 cut on the opposite
side. As you cut the log, it will tend to bend. The
saw can become pinched or hung in the log if you
make the first cut deeper than 1/3 of the diameter
of the log.
Give special attention to logs under stress to
prevent the bar and chain from pinching.

OPERATION
OVERBUCKING
See Figure 28.
Begin on the top side of the log with the bottom
of the saw against the log; exert light pressure
downward. Note that the saw will tend to pull
away from you.
UNDERBUCKING
See Figure 29.
Begin on the underside of the log with the top
of the saw against the log; exert light pressure
upward. During underbucking, the saw will tend
to push back at you. Be prepared for this reaction
and hold the saw firmly to maintain control.
Fig. 28
OVERBUCKING
LIMBING AND PRUNING
See Figures 30 - 31.
Work slowly, keeping both hands on the saw
with a firm grip. Maintain secure footing and
balance.
Keep the tree between you and the chain while
limbing.
Do not cut from a ladder. This is extremely dan-
gerous. Leave this operation for professionals.
Fig. 29
UNDERBUCKING
Do not cut above chest height. A saw held
higher than chest height is difficult to control
against kickback.
WARNING:
Never climb into a tree to limb or prune. Do
not stand on ladders, platforms, a log, or in
any position which can cause you to lose your
balance or control of the saw and cause death
or serious personal injury.
CUT LIMBS ONE AT A TIME AND LEAVE SUPPORT LIMBS

SECOND CUT
When pruning trees it is important not to make
the flush cut next to the main limb or trunk until
you have cut off the limb further out to reduce
the weight. This prevents stripping the bark from
the main limb or trunk.
LOAD
• Underbuck the branch 1/3 through for your
first cut.

WARNING:
If the limbs to be pruned are above shoulder
height, hire a professional to perform the prun-
ing. Cutting above shoulder height could result
in an accident, causing serious personal injury.
CUTTING SPRINGPOLES
See Figure 32.
Fig. 32
SPRINGPOLE
A springpole is any log, branch, rooted stump, or
sapling which 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.
WARNING:
Springpoles are dangerous and could strike the
operator, causing the operator to lose control
of the chain saw. This could result in severe or
fatal injury to the operator.

Use only a low-kickback chain on this saw. This
chain provides kickback reduction when properly
maintained.
For smooth and fast cutting, maintain the chain
properly.
The chain requires sharpening when the wood
chips are small and powdery, the chain must be
forced through the wood during cutting, or the
chain cuts to one side. During maintenance of the
chain, consider the following:
Improper filing angle of the side plate can
increase the risk of severe kickback.
Fig. 47
Depth gauge clearance.
• Too low increases the potential for kickback.
• Not low enough decreases cutting ability.
If the cutter teeth hit hard objects such as nails
and stones, or are abraded by mud or sand
on the wood, have a qualified service center
sharpen the chain.
NOTE: Inspect the drive sprocket for wear
or damage when replacing the chain. If signs
of wear or damage are present in the areas
indicated, have the drive sprocket replaced by
a qualified service center.
NOTE: If you do not fully understand the correct
procedure for sharpening the chain after reading
the instructions that follow, have the saw chain
sharpened by a qualified service center or replace
with a recommended low-kickback chain.

AIR FILTER COVER
CYLINDER
COVER
The chain saw is designed with a ventilation
hatch on the right side of the cylinder cover which
allows warm air to be supplied from the engine to
the carburetor to help prevent icing under colder
operating conditions. Operating the chain saw in
temperaturesfrom32ºFto41ºF(0ºCto5ºC)attimes
of high humidity may result in ice forming within
the carburetor. This can cause the output power of
the engine to be reduced and/or the engine to fail
to operate smoothly. When operating under these
circumstances, the chain saw should be placed in
cold weather mode before use.
