GENERAL POWER TOOL SAFETY WARNINGS
IMPORTANT SAFETY WARNINGS
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
energizing 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
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry 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.

switch with your fingers. (Once the tool is running, you can release the
lock button). To turn the tool OFF, release the trigger switch.
WARNING: To guard against injury, observe the following:
Read instruction manual before using, save instruction
manual.
Keep hands away from chain.
Keep hands on handles. Don’t overreach.
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 operate pole saw to 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.
WARNING: Do not cut trees near electrical wires or buildings.
Proper Cutting Stance
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. Your right hand should be gripping the
handle and positioned firmly against your body for added support.
Your body should always be to the left of the chain line.
CAUTION: Failure to lubricate the chain will cause damage to the bar
and chain. Use only a good quality bar and chain oil or, if not
available, unused SAE 30 weight motor oil may be substituted. One
minute of use will consume approx. 0.15 fl. oz. (5ml) of oil.
NOTE: It is normal for oil to seep from the pole 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 (3 months or longer) be sure the
chain is lightly lubricated; this will prevent rust on the chain and bar
sprocket.
WARNING: Do Not use the pole saw with any type of accessory or
attachment. Such usage might be hazardous.
WARNING: Hold the extended-reach pruner by insulated gripping
surfaces only, because the saw chain may contact hidden wiring or its
own cord. A saw chain contacting a ″live″ wire may make exposed
metal parts of the extended-reach pruner ″live″ and could give the
operator an electric shock.
To reduce the risk of electrocution, never use near any electrical
power lines. Contact with or use near power lines may cause serious
injury or electric shock resulting in death.

Fig. 7
A good, firm grip on the pole saw with both hands will help you
maintain control. Grip the rear handle with your right hand whether you
are right or left handed. Wrap the fingers of your left hand over and
around the pole shaft.. A firm grip together with positioning handle
against your body will help you maintain control of the saw. Don’t let
go.
Do not operate pole saw in a tree, on a ladder, or on a scaffold; this is
extremely dangerous.

OPERATING
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 chain 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 chain 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 chain saw 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:
1. Always grip the pole and handle 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 pole shaft
with your thumbs and fingers encircling the pole saw handle and
shaft. A firm grip together with a stiff left arm will help you maintain
control of the saw if kickback occurs.
2. 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.
3. Always cut with the unit running at full speed. Fully squeeze the
throttle trigger and maintain a steady cutting speed.
4. Wear non-slip gloves for maximum grip protection.
Cut lower branches first to allow the top branches more room to fall.
Work slowly, keeping both hands on the saw with a firm grip.
Maintain secure footing and balance.
WARNING: To protect yourself from electrocution, maintain a min of 50ft
(15m) from over head electrical lines.
Keep bystanders at least 50ft. away.
BASIC CUTTING PROCEDURE
See figure 8-9
Keep the tree between you and the chain while limbing.
Cut from side of tree opposite branch you are cutting.
Do not cut from a ladder; this is extremely dangerous. Leave this
operation for professionals.
Do not use the pole saw for felling or bucking,
To prevent electrocution, do not operate within 50 ft. of overhead
electrical lines,.
Follow the steps below to prevent damage to tree or shrub bark. Do not
use a back-and-forth sawing motion,
Do not make the flush cut next to the main limb or trunk until you have
cut of the limb further out to reduce the weight.
Following proper cutting procedures will prevent stripping bark
from the main member.
Make a shallow first cut (1/4 of limb diameter) on the underside of the
limb close to the main limb or trunk,
Make a second cut from the top side of the limb outboard from the first
cut. Continue the cut through the limb until the limb separates from the
tree. Be prepared to
balance the weight of
the tool when the
limb falls.
Make a final cut
close to the trunk.
Release the trigger as soon as the cut is completed. Failure to follow
proper cutting procedures will result in the bar and chain binding and
becoming pinched or trapped in the limb.
If this should happen:
Stop the motor and remove the battery pack.
If the limb can be reached from the ground, lift the limb while holding the
saw. This should release the “PINCH” and free the saw.
If the saw is still trapped, call a professional for assistance.

LIMBING AND PRUNING
See figure 10
This unit is designed for
trimming small branches
and limbs up to 6 inches
(15cm) in diameter.
For best results, observe
the following precautions.
Plan the cut carefully. Be
aware of the direction in
which the branch will fall.
Branches may fall in
unexpected directions. Do
not stand directly under
the branch being cut.
The most typical cutting application is to position the unit at an angle of
60° or less, depending on the specific situation, as shown. As the angle
of the pole saw shaft to ground increases, the difficulty of making the
first cut (from the underside of the limb) increases.
Remove long branched in several stages.
For second and final cuts, (from top of limb or branch), hold front cutting
guide against the limb being cut. This will help steady the limb and
make it easier to cut. Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, damage to the bar, chain, or
motor can result.
Fig.10

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
replacing the chain. If signs of wear or damage are present in the
areas indicated, have the drive sprocket replaced by a qualified
individual.
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.
CHAIN MAINTENANCE
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 excessive
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.

When fully charged, the battery can be safety stored in temperatures
down to –4° degrees F for a period of up to four weeks, before
requiring charging. Fully charge battery pack every 90 days.
If over a period of time the battery pack quickly runs down after a full
80 minute charging period, a replacement battery pack is needed.
To prevent permanent damage to the battery, never store in a
discharged condition.
WINTER STORAGE—Fully recharge before storage and then again
every 90 days.
Since the battery will not develop a memory, it does not have to be
fully discharged before recharging.
A small leakage of liquid from the battery cells may occur under
extreme usage, charging or temperature conditions. This does
not indicate a failure. However, if the outer seal is broken and this
leakage gets on your skin.
a. Wash quickly with soap and water.
b. Neutralize with a mild acid such as lemon juice or
vinegar.
c. If the battery liquid gets in your eyes, flush them with
clean water for a minimum of 10 minutes and seek
immediate medical attention.
Charge the battery pack only with Yardworks 20V Chargers
Allow at least 80 minutes of charge time before initial use of the
pole saw.
Make sure the power supply is normal household voltage,
120volts, 60Hz, AC only.
The battery charger should be operated in temperatures between
39 and 104 degrees F.
The battery should be charged in a cool, dry place.
Two to Three initial charging/discharging cycles may be required to
achieve maximum run time/capacity.
Do not attempt to open the charger or the unit. There are no
customer serviceable parts inside. Call the customer service help
line at 1-800-633-1501 for assistance.
DO NOT incinerate battery packs even if they are severely
damaged or completely worn out. They can explode in a fire
causing injury.
Use the battery charger indoors only.
Disconnect charger from the power supply when not in use to
prevent damage to the charger during a power surge.

MAINTENANCE
BEFORE USING: Fill oil well with new quality bar and chain oil.
Unused SAE30 weight motor oil may be substituted.
If you drop the pole 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 help line at 1-800-633-1501 for assistance.
Remove the battery pack from the pole saw, 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.
TROUBLESHOOTING
- Bar and chain running hot and
smoking
- Check tension for over-tight condition
- Chain oil tank empty
- Chain installed in wrong direction
- Adjust chain tension
- Fill tank with chain oil

CALL US FIRST !!
- Chain tension too tight
- Check guide bar and chain for damage
- Motor runs but chain is not rotating - Adjust chain tension
- Replace damaged bar and chain with identical replacement
parts.
LUBRICATION SYSTEM
The chain is automatically lubricated.
Use only new bar and chain oil or unused SAE 30 weight motor oil may
be substituted. Never use wasted oil, low quality oil, or insufficient oil.
This could damage the bar and the chain, which may result in serious
personal injury.
Check oil level before each work session, refill if less than ¼ full.
If the lubrication system does not work properly, check if all oil-ways are
clean and free from obstructions. If it is still not working, call our
customer service help line at 1-800-633-1501 for assistance.
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
frequently 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.
Problem
-Unit does not run.
Possible Cause
-Battery not making contact.
-Lock off not fully operated.
-Battery not installed properly
-Battery not charged.
Possible Solutions
-Check the battery is fully inserted
-Check that lock off is fully forward prior to moving trigger
