LCS0620-1
WARNING: Read all safety warnings and 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, 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, jewellery 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.
• Do not use the power tool if the switch does not turn it on
and off. Any power tool that cannot 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 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
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.
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 designated battery
packs. Use of any other battery packs may create a risk of
injury and fire.
TO REDUCE RISK OF INJURY:

understands all safety instructions and other information
contained in this manual.
CAUTION: Wear appropriate personal hearing protection
during use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss.
Save these instructions and review frequently prior to use
and in instructing others.
WARNING: When using electric gardening appliances,
basic safety precautions should always be followed to
reduce risk of fire, electric shock, and personal injury,
including the following:
READ ALL INSTRUCTIONS

PRUNING SAW SAFETY WARNINGS
• Keep all parts of the body away from the saw chain when the
pruning saw is operating. Before you start the pruning saw,
make sure the saw chain is not contacting anything. A moment
of inattention while operating pruning saws may cause
entanglement of your clothing or body with the saw chain.
• Always hold the pruning saw with your right hand on the rear
handle and your left hand on the front handle. Holding the
pruning saw with a reversed hand configuration increases the risk
of personal injury and should never be done.
• Hold the pruning saw 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
pruning saw live and could give the operator an electric shock.
• Wear safety glasses and hearing protection. Further
protective equipment for head, hands, legs and feet is
recommended. Adequate protective clothing will reduce personal
injury by flying debris or accidental contact with the saw chain.
• Do not operate a pruning saw in a tree. Operation of a pruning
saw while up in a tree may result in personal injury.
• Always keep proper footing and operate the pruning 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 pruning saw.
• When cutting a limb that is under tension be alert for spring
back. When the tension in the wood fibers is released the spring
loaded limb may strike the operator and/or throw the pruning 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 pruning saw by the front handle with the pruning
saw switched off and away from your body. When
transporting or storing the pruning saw always use the guide
bar cover. Proper handling of the pruning saw will reduce the
likelihood of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning and
changing accessories. Improperly 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 pruning saw for purposes not
intended. For example: do not use pruning saw for cutting
plastic, masonry or non-wood building materials. Use of the
pruning 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 pruning 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 incorrect 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
pruning 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 operator, if proper
precautions are taken. Do not let go of the pruning saw.
• Do not overreach and do not cut above shoulder height. This
helps prevent unintended tip contact and enables better control of
the pruning 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.
GENERAL POWER TOOL SAFETY WARNINGS
• When battery pack is not in use, keep it away from other met-
al 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 ejected 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 irritation
or burns.
Service
• Have your power tool serviced by a qualified repair person
using only identical replacement parts. This will ensure that
the safety of the power tool is maintained.
• When servicing a power tool, use only identical
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.

OPERATING
TO INSTALL / REMOVE BATTERY PACK
WARNING: Always remove the battery pack from the
product when you are assembling parts, making
adjustments, cleaning, or when not in use. Removing the
battery pack will prevent accidental starting that could cause
serious personal injury.
Slide the battery pack into the pruning saw. Ensure the
battery is securely connected. To remove the battery,
depress the release button and slide battery pack out of tool.
TO TURN THE TOOL ON
Push the trigger release button (A) backward with your
thumb and then squeeze the trigger (B) with your fingers.
(Once the tool is running, you can release the trigger release
button). To turn the tool OFF, release the trigger.
The following precautions should be followed to
minimize kickback:
• Keep all safety items in place on saw. Make sure they
work properly.
• Do not overreach or cut above shoulder height.
• Keep solid footing and balance at all times.
• Stand slightly to the left side of saw. This keeps your
body from being in direct line with chain.
• Do not let Guide Bar nose touch anything when chain is
moving.
• Never try cutting through two logs at same time. Only cut
one log at a time.
• Do not bury the Guide Bar nose or try plunge cut (boring
into wood using Guide Bar nose).
• Watch for shifting of wood or other forces that may pinch
chain.
• Use extreme caution when reentering a previous cut.
• Never use a dull or loose chain. Keep chain sharp with
proper tension.
• Wear non-slip gloves for maximum grip and protection.
WARNING: Do not operate pruning saw in a tree, on a
ladder, or on a scaffold; this is extremely dangerous.
CAUTION: Chain coasts after turned off.
Do not use under wet conditions.
Use extreme caution when cutting small size brush, saplings
or limbs under tension, because slender and tense material
may catch the saw and be whipped toward you, pull you off
balance or spring back.
Do not cut vines and/or small underbrush.
WARNING: Do not allow familiarity with this type of tool to
make you careless. Remember that a careless fraction of a
second is sufficient to inflict serious injury.
Before you start the unit, make sure the pruning saw is not
contacting any object.
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 pruning saw
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 lightening fast, reverse
reaction which kicks the guide bar up and back toward the
operator. If the pruning saw 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
pruning saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
CUTTING INSTRUCTIONS
WARNING: To guard against injury, observe the following:
Read owner’s manual before using,
Save owner’s manual.
Keep hands away from chain.
Keep hands on handles. Don’t overreach.
A good, firm grip on the saw with both hands will help you
maintain control. Don’t let go. Grip the rear handle with your
right hand whether you are right or left handed.
Make sure you follow the instructions in maintenance for
adding oil in the pruning saw.
CAUTION: Chain life and cutting capacity depend on
optimum lubrication. Therefore, the chain should be oiled
before operation.
IMPORTANT: It is important to use bar and chain lubricant
that is formulated to perform over a wide temperature range
with no dilution required. Do not use dirty, used or otherwise
contaminated oil. Damage may occur to the bar or chain. Use
of non-approved oil will void the warranty. Do not swallow. If
swallowed, call a physician immediately. Keep out of reach of
children. Store away from heat or open flame.

OPERATING
LIMBING
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the pruning 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.
Branches under tension should be cut from the bottom up to
avoid binding the pruning saw.
Keep the tree between you and the pruning saw while limbing.
Cut from the side of the tree opposite the branch you are
cutting.
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.
PRUNING
Pruning is trimming limbs from a live tree.
Work slowly, keeping both hands on the pruning saw with a
firm grip. Always make sure your footing is secure and your
weight is distributed evenly on both feet.
When pruning trees it is important not to make the finishing 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 member.
Under-buck the branch 1/3 through for your first cut.
Your second cut should over-buck to drop the branch off.
Now make your finishing cut smoothly and neatly against the
main member so the bark will grow back to seal the wound.
SPRINGPOLES
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.
They could result in severe or fatal injury.
BUCKING
Bucking is the term used for cutting a log to the desired
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 pruning saw
when cutting through the log, release the cutting pressure
near the end of the cut without relaxing your grip on the
pruning 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 pruning saw. Always stop the
motor before moving from log to log.
BUCKING LOGS UNDER STRESS
When the log is supported along its entire length, it should
be cut from the top or over-bucking.
When the log is supported on one end, cut 1/3 diameter from
the underside or under-bucking. Then make the finishing cut
by over-bucking 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 prevent the bar
and chain from pinching.
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.
UNDER-BUCKING – Begin on the under side of the log
with the top of the saw against the log; exert light pressure
upward. During under-bucking, the saw will tend to push
back at you. Be prepared for this reaction and hold the saw
firmly to maintain control.

CHAIN TENSION AND MAINTENANCE
CHAIN TENSION
Remove the battery before setting the chain tension. Make sure the
guide bar screw is loosened to finger tight, turn the chain tensioner
clockwise to tension the chain. A cold chain will be correctly tensioned
when there is no slack on the underside of the guide bar, the chain is
snug, but it can be turned by hand without binding.
Chain must be re-tensioned whenever the flats on the drive links hang
out of the bar groove.
During normal saw operation, the temperature of the chain will
increase. The drive links of a correctly tensioned warm chain will
hang approximately .050 in. (1.25mm) out of the bar groove. Be
aware that chain tensioned while warm, may be too tight upon
cooling. Check the “cold tension” before next use.
NOTE: A new chain tends to stretch, check chain tension frequently
and tension as required.
CHAIN MAINTENANCE
CAUTION: Remove the battery pack and make sure the chain has
stopped before you do any work on the saw.
For smooth and fast cutting, chain needs to be maintained 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 your chain
remember:
- Improper filing angle of the side plate can increase the risk of
severe kickback.
- Raker (depth gauge) clearance.
- Too low increases the potential for kickback.
- Not low enough decreases cutting ability.
- If cutter teeth have hit hard objects such as nails and stones, or
have been abraded by mud or sand on the wood, have service
dealer sharpen chain.
NOTE: Inspect the drive sprocket for wear or damage when replac-
ing the chain. If signs of
wear or damage are pre-
sent in the areas indicat-
ed, have the drive sprocket
replaced. Call our customer
service help line at 1-800-
633-1501 for assis-
tance.
HOW TO SHARPEN THE
CUTTERS
Be careful to file all cutters to the specified angles and to the same
length, as fast cutting can be obtained only when all cutters are
uniform.
Wear gloves for protection. Properly tension the chain prior to
sharpening. Refer to “Chain Tension Section” earlier in this manual.
Do all of your filing at the midpoint of the bar.
Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth. Do not let the file
dip or rock. Using light
but firm pressure,
stroke towards the front
corner of the tooth.
Lift file away from the steel on each return stroke.
Put a few firm strokes on every
tooth. File all left hand cutters
in one direction. Then move to
the other side and file the right
hand cutters in the opposite
direction. Occasionally remove
filing from the file with a wire
brush.
WARNING: Improper chain sharpening increases the potential of
kickback.
WARNING: Failure to replace or repair damaged chain can cause
serious injury.
WARNING: The saw chain is very sharp, always wear protective
gloves when performing maintenance to the chain.
TOP PLATE FILING ANGLE
Correct 30 degrees – File holders are marked with guide marks to
align file properly to produce top plate angle.
Less than 30 degrees – for
cross cutting.
More than 30 degrees –
feathered edge dulls quickly.
SIDE PLATE ANGLE
Correct – 80 degrees produced
automatically if correct diameter file is used in file holder.
Hook – “Grabs” and dulls quickly.
Increases potential of kickback.
Results from using a file with a
diameter too small, or file held to
low.
Backward Slope – Needs too
much feed pressure, causes ex-
cessive wear to bar and chain. Results from using a file with a
diameter too large, or file held too high.
DEPTH GAUGE CLEARANCE
The depth gauge should be
maintained at a clearance of .025
in. (0.6 mm). Use a depth gauge
tool for checking the depth gauge
clearances.
Every time the chain is filed, check
the depth gauge clearance
Use a flat file and a depth gauge
jointer to lower all gauges uniformly.
Depth gauge jointers are available
in .020 in. to .035 in. (0.5 mm to 0.9
mm). Use a .025 in. (0.6 mm) depth
gauge jointer. After lowering each
depth gauge, restore original shape
by rounding the front. Be careful not
to damage adjoining drive links with
the edge of the file.
Depth gauges must be adjusted with
the flat file in the same direction the
adjoining cutter was filed with the
round file. Use care not to contact cutter face with flat file when
adjusting depth gauges.
Approx. .050 (1.25mm)

MAINTENANCE
BEFORE USING : Chain life and cutting capacity depend on
optimum lubrication. Therefore, the chain should be oiled
before operation.
If you drop the pruning saw, carefully inspect it for damage.
If the blade is bent, housing cracked, or handles broken
or if you see any other condition that may affect the saw’s
operation, call our customer service line at 1-800-633-1501
for assistance.
Make sure the battery is detached from the unit, then use
only mild soap and a damp cloth to clean the tool. Never let
any liquid get inside the tool; never immerse any part of the
tool into a liquid.
IMPORTANT: To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment should be performed by
a qualified individual always using identical replacement
parts.
CAUTION: Do not at any time let brake fluids, gasoline,
petroleum based products, penetrating oils, etc., come in
contact with plastic parts. They contain chemicals that can
damage, weaken or destroy plastic.
Ensure that the plastic bar cover is in place when storing.
Fertilizers and other garden chemicals contain agents which
greatly accelerate the corrosion of metals Do not store the
tool on or adjacent to fertilizers or chemicals.
For smooth and fast cutting, chain needs to be maintained
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. Refer to instructions earlier in this manual for
instructions on properly sharpening the chain.

Switch off the pruning saw and remove the battery. Place the
pruning saw on a level surface with the Housing-Cover facing
up. Clean the Guide Bar
and Chain with a soft
brush or solvent. Apply
lubrication oil in area (a)
between Guide Bar and
Chain. Fit the battery
Switch on the pruning
saw. Lubrication oil is
evenly distributed over
the chain. The saw
chain is lubricated.
GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear, reverse it on the saw
to distribute the wear for maximum bar life. The bar should be
cleaned every day of use and checked for wear and damage.
Feathering or burring of the bar rails is a normal process of bar
wear. Such faults should be smoothed with a file as soon as
they occur.
A bar with any of the following faults should be replaced.
− Wear inside the bar rails which permits the chain to lay over
sideways.
− Bent guide bar
− Cracked or broken rails
− Spread rails
In addition, guide bars with a sprocket at their tip must be
lubricated weekly with a grease syringe to extend the guide bar
life. Using a grease syringe, lubricate weekly in the lubricating
hole.
Turn the guide bar and check that the lubrication holes and
chain groove are free from obstructions.
