GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for future
reference.The term “power tool” in the warnings
refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
WORK AREA SAFETY
Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded)
power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
If operating a power tool in a damp location
is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a
GFCI reduces the risk of electric shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and
use common sense when operating a power
tool. Do not use a power tool while you are
tired or under the influence of drugs, alcohol
or medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, pick-
ing up or carrying the tool. Carrying power
tools with your finger on the switch or energis-
ing power tools that have the switch on invites
accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool
may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
Page 4 — English
GENERAL POWER TOOL SAFETY WARNINGS
Do not use the power tool if the switch does
not turn it on and off. Any power tool that can-
not be controlled with the switch is dangerous
and must be repaired.
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions
to operate the power tool. Power tools are
dangerous in the hands of untrained users.
Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage of
parts and any other condition that may affect
the power tool’s operation. If damaged, have
the power tool repaired before use. Many
accidents are caused by poorly maintained
power tools.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
SERVICE
Have your power tool serviced by a qualified
repair person using only identical replace-
ment parts. This will ensure that the safety of
the power tool is maintained.
When servicing a power tool, use only identi-
cal replacement parts. Follow instructions
in the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
shock or injury.
Page 5 — English
CHAIN SAW SAFETY WARNINGS
Keep all parts of the body away from the
saw chain when the chain saw is operating.
Before you start the chain saw, make sure
the saw chain is not contacting anything. A
moment of inattention while operating chain
saws may cause entanglement of your clothing
or body with the saw chain.
Always hold the chain saw with your right
hand on the rear handle and your left hand on
the front handle. Holding the chain saw with a
reversed hand configuration increases the risk
of personal injury and should never be done.
Hold the power tool by insulated gripping
surfaces only, because the saw chain may
contact hidden wiring or its own cord. Saw
chains contacting a "live" wire may make
exposed metal parts of the power tool "live"
and could give the operator an electric shock.
Wear safety glasses and hearing protec-
tion. Further protective equipment for head,
hands, legs and feet is recommended. Ade-
quate protective clothing will reduce personal
injury by flying debris or accidental contact with
the saw chain.
Do not operate a chain saw in a tree. Opera-
tion of a chain saw while up in a tree may result
in personal injury.
Always keep proper footing and operate
the chain saw only when standing on fixed,
secure and level surface. Slippery or unstable
surfaces such as ladders may cause a loss of
balance or control of the chain saw.
When cutting a limb that is under tension be
alert for spring back. When the tension in the
wood fibres is released the spring loaded limb
may strike the operator and/or throw the chain
saw out of control.
Use extreme caution when cutting brush and
saplings. The slender material may catch the
saw chain and be whipped toward you or pull
you off balance.
Carry the chain saw by the front handle with
the chain saw switched off and away from
your body. When transporting or storing the
chain saw always fit the guide bar cover.
Proper handling of the chain saw will reduce the
likelihood of accidental contact with the moving
saw chain.
Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improp-
erly tensioned or lubricated chain may either
break or increase the chance for kickback.
Keep handles dry, clean, and free from oil
and grease. Greasy, oily handles are slippery
causing loss of control.
Cut wood only. Do not use chain saw for
purposes not intended. For example: do not
use chain saw for cutting plastic, masonry
or non-wood building materials. Use of the
chain saw for operations different than intended
could result in a hazardous situation.
CAUSES AND OPERATOR PREVENTION
OF KICKBACK
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 sudden
reverse reaction, kicking the guide bar up and
back towards the operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards
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 your saw. As a chain saw
user, you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces.
Kickback forces can be controlled by the opera-
tor, if proper precautions are taken. Do not let
go of the chain saw.
Page 6 — English
CHAIN SAW SAFETY WARNINGS
Do not overreach and do not cut above
shoulder height. This helps prevent unintended
tip contact and enables better control of the
chain saw in unexpected situations.
Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause chain
breakage and/or kickback.
Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback. Do not start
cutting until you have a clear work area, secure
footing, and a planned retreat path from the
falling tree. Cluttered areas invite accidents.
Keep ALL children, bystanders, visitors, and
animals out of the work area while starting or
cutting with the chain saw. Do not let visitors
contact chain saw or extension cord.
Do not operate chain saw in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Chain saws create
sparks which may ignite the dust or fumes.
WARNING: Use outdoor extension cords
marked SW-A, SOW-A, STW-A, STOW-A,
SJW-A, SJTW-A, or SJTOW-A. These cords
are rated for outdoor use and reduce the risk
of electric shock.
Polarized Plugs. To reduce the risk of electric
shock, this tool has a polarized plug (one blade
is wider than the other). This plug will fit in a
polarized outlet only one way. If the plug does
not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician
to install the proper outlet. Do not change the
plug in any way.
Make sure your extension cord is in good condi-
tion. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. A wire gauge size (A.W.G.)
of at least 14 is recommended for an extension
cord 50 feet or less in length. A cord exceeding
100 feet is not recommended. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord. An undersized
cord will cause a drop in line voltage resulting
in loss of power and overheating.
Inspect extension cords periodically and, if
damaged, have repaired by a licensed electri-
cian. Constantly stay aware of cord location.
Following this rule will reduce the risk of electric
shock or fire.
Dress Properly - Wear snug fitting clothing.
Always wear heavy, long pants, long sleeves,
overalls, jeans or chaps made of cut resistant
material or ones that contain cut resistant
inserts. Wear non-slip safety footwear. Wear
non-slip heavy duty gloves to improve your
grip and to protect your hands. Do not wear
jewelry, short pants, sandals, or go barefoot.
Do not wear loose fitting clothing, which could
be drawn into the motor or catch the chain or
underbrush. Secure hair so it is above shoulder
level. Wear hearing and head protection.
Heavy protective clothing may increase operator
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.
Always wear eye protection with side shields
marked to comply with ANSI Z87.1 as well as
head protection when operating this equipment.
Always be aware of what you are doing when
using the chain saw. Use common sense. Do
not operate the chain saw when you are tired,
ill, or under the influence of alcohol, drugs, or
medication.
Do not expose the chain saw to rain.
Do not use the chain saw in damp or wet loca-
tions.
Always be aware of extension cord while oper-
ating chain saw. Take precautions to avoid
tripping over cord. Keep cord away from chain
and operator at all times. Never carry saw by
the cord or pull it to disconnect from receptacle.
Keep cord from oil and sharp edges.
Stay alert and pay attention to what you are
doing. Use common sense when using this unit.
Keep all parts of your body away from the saw
chain when the unit is running.
Page 7 — English
CHAIN SAW SAFETY WARNINGS
Never let anyone use your chain saw who has
not received adequate instructions in its proper
use. This applies to rentals as well as privately
owned saws.
Before you start the unit, make sure the saw
chain is not contacting any object.
Stop the chain saw before setting it down.
To avoid accidental starting, never carry the unit
with your finger on the switch trigger.
Maintain the unit with care. Keep the cutting
edge sharp and clean for best performance and
to reduce the risk of injury. Follow instructions
for lubricating and changing accessories.
Do not operate a chain saw with one hand! Use
a firm grip with thumbs and fingers encircling the
chain saw handles. Serious injury to the opera-
tor, helpers, bystanders, or any combination
of these persons may result from one-handed
operation. A chain saw is intended for two-
handed use.
Guard against electric shock - Avoid body
contact with grounded surfaces such as metal
pipes and wire fences. There is an increased
risk of electric shock if your body is grounded.
Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and
securely assembled. Chain should slow to a
stop when the switch trigger is released. If the
chain continues to turn after the switch trigger
has been released, have the unit serviced by
your nearest Homelite service dealer.
Check for damaged parts. Check for alignment
of moving parts, binding of moving parts, break-
age of parts, mounting, and any other condi-
tions that may affect its operation. A guard or
other part that is damaged should be properly
repaired or replaced by an authorized service
dealer unless otherwise indicated elsewhere in
this manual.
All chain saw service, other than the items listed
in the operation and maintenance sections,
should be performed by your nearest Homelite
service dealer.
Always maintain a proper stance.
Do not use chain saw if switch does not turn it
on and off. Have defective switch replaced by
authorized service center.
Do not adapt your powerhead to a bow guide
or use it to power any attachments or devices
not listed for the saw.
Disconnect chain saw from power supply when
not in use, before servicing, and when making
adjustments and changing attachments, such
as saw chain and guard.
Do not cut vines and/or small underbrush.
Do not operate a chain saw in a tree, on a ladder,
rooftop, scaffold, or other unstable support; this
is extremely dangerous.
NOTE: The size of the work area depends on
the job being performed as well as the size tree
or work piece involved. For example, felling a
tree requires a larger work area than making
bucking cuts.
Do not force the chain saw. The job can be
performed better and safer at the rate for which
it was intended.
Always use the right product for your applica-
tion. The chain saw should be used for cutting
wood only. Never use the chain saw to cut
plastic, masonry or non-wood building materi-
als.
Store chain saw when not in use. Chain saw
should be stored in a dry and high or locked
area out of the reach of children. When storing
chain saw place the scabbard on the bar and
chain and store the chain saw in carrying case.
Save these instructions. Refer to them fre-
quently and use them to instruct others who
may use this product. If you loan someone this
product, loan them these instructions also.

CHAIN SAW SAFETY WARNINGS
Fig. 2
KICKBACK
See Figures 1 - 2.
WARNING:
Kickback may occur 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 reactions can cause
loss of saw control which can result in serious
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 cut-
ting jobs free from accident or injury.
The following precautions should be followed
to minimize kickback:
Always grip the saw firmly with both hands.
Hold the saw firmly with both hands when
the unit 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 kickback occurs.
Make sure that the area in which you are cut-
ting 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.
Always cut with the unit running. Fully
squeeze the switch trigger and maintain cut-
ting speed.
Use replacement parts such as low kickback
chain, SAFE-T-TIP
®
anti-kickback nose
guards and special guide bars that reduce
the risks associated with rotational kickback.
Use only the replacement guide bars and low
kickback chains specified by the manufac-
turer for the saw.
With a basic understanding of kickback, you
can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
Do not overreach. Keep proper footing and
balance at all times.
Do not cut above shoulder height or overreach
when cutting. Don’t let nose of Guide Bar con-
tact log, branch, ground or other obstruction.
Keep the SAFE-T-TIP
®
anti-kickback nose guard
properly mounted on the guide bar to prevent
rotational kickback.
Follow the sharpening and maintenance instruc-
tions for the saw chain.
Push and Pull - This reaction force is always
opposite to the direction the chain is moving
where wood contact is made. Thus, the operator
must be ready to control the PULL when cutting
on the bottom edge of the bar, and PUSH when
cutting along the top edge. See Figure 3.

The SAFE-T-TIP
®
prevents rotational kickback
from happening, because it covers the tip of the
bar where kickback is generated. Never attempt
any kind of cutting where the SAFE-T-TIP
®
would
have to be removed from the bar tip.
LOW KICKBACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter
can minimize the force of a kickback reaction by
preventing the cutters from digging in too deeply
at the kickback zone. Only use replacement chain
that is equivalent to original chain or has been
certified as low kickback chain per ANSI B175.1.
Low kickback/skip tooth saw chain is a chain that
has met the kickback performance requirements
of ANSI B175.1 - 1991 (American National Stan-
dard for Power Tools - Gasoline-Powered Chain
Saws-Safety Requirements) when tested on the
representative sample of chain saws below 3.8
c.i.d. specified in ANSI B175.1 - 1991.
As saw chains are sharpened during their useful
life, they lose some of the low kickback qualities
and extra caution should be used.
GUIDE BARS
Generally, guide bars with small radius tips have
somewhat lower kickback potentials.
When making a replacement, be sure to order
one of the Homelite bars listed for the saw in this
operator’s manual. The proper size SAFE-T-TIP
®
nose guard comes installed on the bar. Use only
guide bars that have a provision for mounting the
SAFE-T-TIP
®

Before using any extension cord, inspect it for loose
or exposed wires and cut or worn insulation.
A proper extension cord is available at an authorized
service center.
It is possible to tie the extension cord and power
cord in a knot to prevent them from becoming
disconnected during use. Make the knot as shown
in figure 5, then connect the plug end of the power
cord into the receptacle end of the extension cord.
This method can also be used to tie two extension
cords together.
DOUBLE INSULATION
Double insulation is a concept in safety in electric
power tools, which eliminates the need for the usual
three-wire grounded power cord. All exposed metal
parts are isolated from the internal metal motor
components with protecting insulation. Double
insulated tools do not need to be grounded.
WARNING:
The double insulated system is intended to
protect the user from shock resulting from a
break in the tool’s internal insulation. Observe
all normal safety precautions to avoid electrical
shock.
NOTE: Servicing of a product with double insulation
requires extreme care and knowledge of the system
and should be performed only by a qualified service
technician. For service, we suggest you return the
product to your nearest authorized service center
for repair. Always use original factory replacement
parts when servicing.
ELECTRICAL CONNECTION
This product has a precision-built electric motor.
It should be connected to a power supply that is
120V, AC only (normal household current), 60
Hz. Do not operate this product on direct current
(DC). A substantial voltage drop will cause a loss of
power and the motor will overheat. If the product
does not operate when plugged into an outlet,
double-check the power supply.
EXTENSION CORDS
See Figure 5.
When using a power tool at a considerable
distance from a power source, be sure to use
an extension cord that has the capacity to
handle the current the product will draw. An
undersized cord will cause a drop in line voltage,
resulting in overheating and loss of power. Use the
chart to determine the minimum wire size required
in an extension cord. Only round jacketed cords
listed by Underwriter’s Laboratories (UL) should
be used.
When working outdoors with a product, use an
extension cord that is designed for outside use.
This type of cord is designated with “W-A” or “W”
on the cord’s jacket.

PROPER GRIP ON HANDLES
See Figure 10.
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.
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
motor 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:
DO NOT operate the switch
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. Improper
operation of the chain saw could result in seri-
ous personal injury.
PROPER CUTTING STANCE
See Figure 11.
WARNING:
Always use the proper cutting stance described
in this section. Never kneel when using the
chain saw, except when felling a tree as illus-
trated in Figure 12. Kneeling could result in
loss of stability and control of the chain saw,
resulting in serious personal injury.
Page 20 — English
OPERATION
Fig. 12
Balance your weight with both feet on solid
ground.
Keep left arm with elbow locked in a “straight
arm” position to withstand any kickback force.
Keep your body to the left of the chain line.
Keep your thumb on underside of handlebar.
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.
Press the switch lock-out and squeeze the
switch trigger then release switch lock-out 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 switch trigger 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
See Figure 12.
Cut only wood or materials made from wood;
no sheet metal, no plastics, no masonry, no
non-wood building materials.
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
adequate instructions for the safe and proper
use of this chain saw.
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.
Always cut with both feet on solid ground to
prevent being pulled off balance.
Do not cut above shoulder height as a saw held
higher is difficult to control against kickback
forces.
Do not fell trees near electrical wires or build-
ings. Leave this operation for professionals.
Cut only when visibility and light are adequate
for you to see clearly.
FELLING TREES
See Figures 13 - 16.
HAZARDOUS CONDITIONS
WARNING:
Do not fell trees during periods of high wind or
heavy precipitation. Wait until the hazardous
weather has ended.
WARNING:
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.
