GENERAL POWER TOOL SAFETY RULES
WARNING:
Read all safety warnings, instructions, illus-
trations and specifications provided with this
power tool. Failure to follow all instructions
listed below 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 atmo-
spheres, 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 elec-
tric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet con-
ditions. 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 inter-
rupter (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 medi-
cation. 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, picking
up or carrying the tool. Carrying power tools
with your finger on the switch or energising 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.

GENERAL POWER TOOL SAFETY RULES
Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action
can cause severe injury within a fraction of a
second.
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.
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 chil-
dren 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 misalignment
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 acci-
dents 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.
Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for
safe handling and control of the tool in unex-
pected situations.
BATTERY TOOL USE AND CARE
Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire
when used with another battery pack.
Use power tools only with specifically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fire.
When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
Under abusive conditions, liquid may be eject-
ed from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irrita-
tion or burns.
Do not use a battery pack or tool that is dam-
aged or modified. Damaged or modified batter-
ies may exhibit unpredictable behaviour resulting
in fire, explosion or risk of injury.
Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or
temperature above 265°F may cause explosion.
Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specified in the instruc-
tions. Charging improperly or at temperatures
outside the specified range may damage the
battery and increase the risk of fire.

CHAINSAW SAFETY WARNINGS
This chain saw is not intended for tree felling.
Use of the chain saw for operations different
than intended could result in serious injury to
the operator or bystanders.
Keep all parts of the body away from the saw
chain when the chainsaw is operating. Before
you start the chainsaw, make sure the saw
chain is not contacting anything. A moment
of inattention while operating chainsaws may
cause entanglement of your clothing or body
with the saw chain.
Always hold the chainsaw with your right
hand on the rear handle and your left hand
on the front handle. Holding the chainsaw with
a reversed hand configuration increases the risk
of personal injury and should never be done.
Hold the chainsaw by insulated gripping
surfaces only, because the saw chain may
contact hidden wiring. 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 eye protection. Further protective
equipment for hearing, head, hands, legs
and feet is recommended. Adequate protec-
tive equipment will reduce personal injury from
flying debris or accidental contact with the saw
chain.
Do not operate a chainsaw, on a ladder, from
a rooftop, or any unstable support. Operation
of a chainsaw in this manner could result in seri-
ous personal injury.
NOTE: The size of the work area depends on
the job being performed as well as the size tree
or work piece involved.
Do not operate a chainsaw in a tree unless
you have been specifically trained to do so.
Operation of a chainsaw in a tree without proper
training could increase the risk of serious per-
sonal injury.
Always keep proper footing and operate
the chainsaw 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 chainsaw.
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
chainsaw 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.
GENERAL POWER TOOL SAFETY RULES
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.
Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
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 main-
tenance instructions may create a risk of shock
or injury.

5 - English
Follow all instructions when clearing jammed
material, storing or servicing the chainsaw.
Make sure the switch is off and the battery
pack is removed. Unexpected actuation of the
chainsaw while clearing jammed material or
servicing may result in serious personal injury.
Carry the chainsaw by the front handle with
the chainsaw switched off and away from
your body. When transporting or storing
the chainsaw always fit the guide bar cover.
Proper handling of the chainsaw will reduce the
likelihood of accidental contact with the moving
saw chain.
Follow instructions for lubricating, chain
tensioning and changing the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
Cut wood only. Do not use chainsaw for
purposes not intended. For example: do not
use chainsaw for cutting plastic, masonry
or non-wood building materials. Use of the
chainsaw 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
reversereaction,kicking the guide barup 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 chainsaw
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 chainsaw 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 chainsaw.
Do not overreach and do not cut above chest
height. This helps prevent unintended tip con-
tact and enables better control of the chainsaw
in unexpected situations.
Only use replacement bars and chains speci-
fied by the manufacturer. Incorrect replace-
ment bars and chains may cause chain break-
age 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 acci-
dents.
Keep ALL children, bystanders, visitors, and
animals out of the work area while starting or
cutting with the chainsaw. Do not let visitors
contact chainsaw or extension cord.
Do not operate chainsaw in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Chainsaws create sparks
which may ignite the dust or fumes.
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
CHAINSAW SAFETY WARNINGS

6 - English
CHAINSAW SAFETY WARNINGS
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. Dur-
ing 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
hearing and head protection when operating
this equipment.
Always be aware of what you are doing when
using the chainsaw. Use common sense. Do
not operate the chainsaw when you are tired, ill,
upset, or under the influence of alcohol, drugs,
or medication.
Do not expose the chainsaw to rain.
Do not use the chainsaw in damp or wet
locations.
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.
Never let anyone use your chainsaw 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 chainsaw 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 chainsaw with one hand! Use a
firm grip with thumbs and fingers encircling the
chainsaw handles. Serious injury to the opera-
tor, helpers, bystanders, or any combination
of these persons may result from one-handed
operation. A chainsaw is intended for two-
handed use.
Guard against electric shock – Avoid body con-
tact 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 chainsaw 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 an
authorized service center.
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
center unless otherwise indicated elsewhere in
this manual.
All chainsaw service, other than the items listed
in the operation and maintenance sections,
should be performed by an authorized service
center.
Always maintain a proper stance.
Do not use chainsaw if switch does not turn it on
and off. Have switch replaced by an authorized
service center.
Do not adapt your power head to a bow guide
or use it to power any attachments or devices
not listed for the saw.
Disconnect chainsaw 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.

KICKBACK
See Figures 1 - 3.
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 reac-
tions 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
chainsaw user, you should take several steps
to keep your cutting 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 chainsaw handles. A firm grip
together with a stiff left arm will help you main-
tain 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 at full speed.
Fully squeeze the throttle trigger and maintain
a steady cutting speed.
Do not force the chainsaw. The job can be per-
formed better and safer at the rate for which it
was intended.
When clearing jammed material or servicing
the unit, make sure all power switches are off
and the battery pack is removed or discon-
nected. Unexpected actuation of the chainsaw
while clearing jammed material or servicing may
result in serious personal injury.
Always use the right product for your applica-
tion. The chainsaw should be used for cutting
wood only. Never use the chainsaw to cut plas-
tic, masonry or non-wood building materials.
Store chainsaw when not charging or when not
in use. Chainsaw should be stored in a dry and
high or locked area out of the reach of children.
When storing chainsaw place the scabbard on
the bar and chain.
Use this product only with batteries and char-
gers listed in tool/appliance/battery pack/char-
ger correlation supplement 988000-842.
Battery operated units do not have to be
plugged into an electrical outlet; therefore, they
are always in operating condition. Be aware
of possible hazards even when unit is not
operating.
Remove the battery pack from the chainsaw
when not charging and before cleaning, servic-
ing, storing, removing material from the unit,
changing accessories such as the bar and
chain, or when not in use.
Never use water or any liquids to clean or rinse
off your product and do not expose the product
to rain or wet conditions. Store indoors in a dry
area. Corrosive liquids, water, and chemicals
can enter the product’s electronic components
and/or battery compartment and damage elec-
tronic components and/or the battery pack,
which can result in a short circuit, increased risk
of fire, and serious personal injury. Remove any
buildup of dirt and debris by wiping the product
clean with a dry cloth occasionally.
CHAINSAW SAFETY WARNINGS

8 - English
• Use replacement parts such as low kick-
back chain, chain brakes 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 manufacturer 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 bal-
ance at all times.
Do not cut above chest height or overreach
when cutting. Do not let the nose of the guide
bar contact a log, branch, ground, or any other
obstruction while you are operating the unit.
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.
UNDERSTANDING YOUR CHAINSAW
SAFETY DEVICES
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 saw chain is chain that has met
the kickback performance requirements of ANSI
B175.1 – 2012 (American National Standard for
Power Tools – Gasoline-Powered Chainsaws-
Safety Requirements) when tested on the repre-
sentative sample of chainsaws below 3.8 c.i.d.
specified in ANSI B175.1 - 2012.
As saw chains are sharpened during their useful
life, they lose some of the low kickback qualities
and extra caution should be used.

OPERATION
Use bar and chain lubricant (not provided) that is
formulated to perform over a wide temperature
range with no dilution required.
NOTE: Do not use dirty, used or otherwise con-
taminated lubricants. Damage may occur to the
bar or chain.
Carefully pour the bar and chain lubricant into
the tank.
Check and fill the oil tank when battery is
recharged, or as needed.

16 - English
NOTE: It is normal for lubricant to seep from the
saw when not in use. To prevent seepage, empty
the oil tank after each use. When storing the unit
for a long period of time (three months or longer) be
sure the chain is lightly lubricated; this will prevent
rust on the chain and bar sprocket.
NOTICE:
Before each use, check to make sure that the
chain is properly tensioned. A cold chain is cor-
rectly tensioned when there is no slack on the
underside of the guide bar, the chain is snug,
and it can be turned by hand without binding.
During normal saw operation, the temperature
of the chain increases. The drive links of a cor-
rectly tensioned warm chain will hang approxi-
mately .050 in. out of the bar groove.
See the Adjusting the Chain Tension instruc-
tions in the Maintenance section of this manual
to properly adjust the chain tension.

PREPARATION FOR CUTTING
PROPER GRIP ON HANDLES
See Figures 9 - 10.
Refer to General Power Tool Safety Rules earlier
in this manual 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.

OPERATION
WARNING:
Never use a left-handed (cross-handed) grip, or
any stance which would place your body or arm
across the chain line. Improper operation of the
chainsaw could result in serious personal injury.
Maintain a proper grip on the saw whenever
the unit 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 danger-
ous 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 chainsaw could result in serious
personal injury.
PROPER CUTTING STANCE
See Figure 11.
WARNING:
Always use the proper cutting stance described
in this section. Never kneel when using the
chainsaw. Kneeling could result in loss of sta-
bility and control of the chainsaw, resulting in
serious personal injury.
Weight should be balanced with both feet on
solid ground.
Keep left arm with elbow locked in a “straight
arm” position to withstand any kickback force.

18 - English
Your body should always be to the left of the
chain line.
Thumb should be on underside of handlebar.
BASIC CUTTING PROCEDURE
Practicecuttingafewsmalllogs 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 off.
Squeeze the switch trigger 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. If you force the cut, dam-
age to the bar, chain, or unit can result.
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
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 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 bucking operations, keep a mini-
mum distance of 15 feet between workers.
Always cut with both feet on solid ground to
prevent being pulled off balance.

19 - English
Do not cut above chest height, as a saw held
higher is difficult to control against kickback
forces.
Cut only when visibility and light are adequate
for you to see clearly.
BUCKING
See Figures 13 - 15.
Bucking is the term used for cutting a fallen tree
to the desired log length.
Always make sure your footing is secure and
your weight is distributed evenly on both feet.
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.
When bucking on a slope, always stand on
the uphill side of the log. To maintain complete
control of the chainsaw when cutting through
the log, release the cutting pressure near the
end of the cut without relaxing your grip on the
chainsaw handles. Do not let the chain contact
the ground. After completing the cut, wait for
the saw chain to stop before you move the
chainsaw. Always stop the motor before moving
from tree to tree.
Sometimes it is impossible to avoid pinching
(with just standard cutting techniques) or difficult
to predict which way a log will settle when cut.
To avoid pinching while cutting, rotate or move
the log so that the pinch is eliminated.

BUCKING LOGS UNDER STRESS
See Figures 15 - 16.
When the log is supported along its entire length,
it should be cut from the top or overbucking.
When the log is supported on one end, cut 1/3
the diameter from the underside or underbuck-
ing. Then make the finishing cut by overbucking
to meet the first cut.
As the log is being cut, 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 pre-
vent the bar and chain from pinching.
TYPES OF CUTTING USED
See Figure 16.
OVERBUCKING
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
Begin on the under side 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.
LIMBING
See Figure 17.
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 bal-
ance or control of the saw, which could result
in death or other serious personal injury.

Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the chain-
saw with a firm grip. Always make sure your
footing is secure and your weight is distributed
evenly on both feet.
Leave the larger support limbs under the tree to
keep the tree off the ground while cutting.
Limbs should be cut one at a time. Remove the
cut limbs from the work area often to help keep
the work area clean and safe.
