SAFETY GUIDELINES
• Keep children away. All visitors should be kept at a distance away from work area.
• Dress properly. Do not wear loose clothing or jewellery. They can be caught in moving parts.
Use of rubber gloves and substantial footwear is recommended when working outdoors. Wear
protective hair covering to contain long hair.
• Use safety glasses. Always use face or dust mask if operation is dusty.
• Use right appliance. Do not use appliance for any job except that for which it is intended.
• Don’t grasp the exposed cutting blades or cutting edges when picking up or holding
the appliance.
• Don’t force appliance. It will do the job better and with less likelihood of a risk of injury at the
rate for which it was designed.
• Don’t overreach. Keep proper footing and balance at all times.
• Stay alert. Watch what you are doing. Use common sense. Do not operate appliance when you
are tired.
• Keep all parts of the body away from the saw chain. Do not remove cut material or hold
material to be cut when blades are moving. Make sure the switch is off when clearing jammed
material. Saw chain continues to move after the switch is turned off. A moment of inattention
while operating the pole saw may result in serious personal injury.
• Carry the pole saw by the handle with the saw chain stopped. When transporting or
storing the pole saw, always fit the saw chain device cover. Proper handling of the pole saw will
reduce possible personal injury from the saw chain.
• Hold the pole saw by insulated gripping surfaces only because the saw chain may
contact hidden wiring. A saw chain contacting a “live” wire may make exposed metal parts of
the pole saw “live” and could give the operator an electric shock.
• Do not use the pole saw in bad weather conditions, especially when there is a risk of
lightning. This decreases the risk of being struck by lightning.
• 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.
• Always use two hands when operating the pole saw. Hold the pole saw with both hands to
avoid loss of control.
• Always use head protection when operating the pole saw overhead. Falling debris can
result in serious personal injury.
• Store idle appliances indoors. When not in use, appliances should be stored indoors in a dry
and high or locked-up place with the battery pack removed−out of reach of children.
• Maintain appliance with care. Keep cutting edge sharp and clean for best performance and
to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Keep
handles dry, clean, and free from oil and grease.

SAFETY GUIDELINES
• Check damaged parts. Before further use of the product, a guard or other part that is damaged
should be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other condition that may affect the tool’s operation. A guard or other part
that is damaged should be properly repaired or replaced by an authorized service centre unless
indicated elsewhere in this manual.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to
battery pack, picking up or carrying the appliance. Carrying the appliance with your finger on the
switch or energizing appliance that have the switch on invites accidents.
• Disconnect the battery pack from the appliance before making any adjustments,
changing accessories, or storing appliance. Such preventive safety measures reduce the
risk of starting the appliance accidentally.
• 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 appliances only with specifically designated 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 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.
• Do not use a battery pack or appliance that is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or
temperature above 130°C (265°F) may cause an explosion.
• Follow all charging instructions and do not charge the battery pack or appliance outside of the
temperature range specified in the instructions. Charging improperly or at temperatures outside
of the specified range may damage the battery and increase the risk of fire.
• Have servicing performed by a qualified repair person using only identical replacement parts. This
will ensure that the safety of the product is maintained.
• Do not modify or attempt to repair the appliance or the battery pack (as applicable) except as
indicated in the instructions for use and care.

the rear pole with the carabiner hook.
2. Adjust the length of the strap to attain a comfortable
working position.
FILLING OIL TANK WITH BAR AND CHAIN
LUBRICANT (
fig. 4
)
The pole saw is not filled with oil at the time of
purchase. It is essential to fill the tank with oil before
use. Operating the pole saw without chain oil or when the oil level is below the minimum mark will
result in damage to the saw. Chain life and cutting
capacity depend on optimum lubrication. The chain
is automatically lubricated with chain oil from the
tank during operation.
1. Remove the battery pack from the pole saw.
2. Clean the oil tank cap and the area around it to
ensure that no dirt falls into the oil tank.
3. Position the pole saw on its side on a firm, flat
surface, so that the oil tank cap is facing upwards.
Rotate the oil tank cap counter-clockwise to remove
it.
4. Carefully pour the oil into the tank. Fill to the bottom of the fill neck. Wipe off any excess oil.
5. Replace the cap, place the saw upright, and view the level through the oil inspection window. Oil should fill
the window.
fig. 4 Oil tank cap
Oil tank
OPERATING INSTRUCTIONS
WARNING!
• Do not smoke or bring any fire or flame near the oil or the saw. Oil may spill and cause a fire.
FPO
NOTICE:
• Never use oil or other lubricants not specifically designed for use on the bar and chain. This can lead to a clogged oil
system, which may cause premature wear of the bar and chain.
• Check the oil level frequently and fill when the oil level falls below the minimum line. Never operate the pole saw if the oil
is not visible.
• Do not use dirty, used, or otherwise contaminated oil. Damage may occur to the bar or chain.
• It is normal for oil to seep from the saw when it is not in use. To prevent seepage, empty the oil tank after each use, and
then run the saw for one minute. When storing the tool for a long period of time, be sure the chain is lightly lubricated; this
will prevent rust on the chain and bar sprocket.

BASIC CUTTING (
fig. 7
)
1. Take the proper stance in front of the tree with the
saw off. The most typical cutting application is to
position the unit at an angle of 60° or less depending
on the specific situation. As the angle of the pole saw
shaft to the ground increases, the difficulty of making
the first cut increases.
2. Start the tool to make a shallow first cut (1/4 of the
limb diameter) on the underside of the limb, close to
the main limb or trunk.
3. 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.
4. Make a final cut close to trunk.
5. Release the trigger switch as soon as the cut is
completed.
fig. 7a
OPERATING INSTRUCTIONS
• Never cut near power lines, electric cords, or other electric sources. If the bar and chain jams on any
electrical cord or line, DO NOT TOUCH THE BAR, CHAIN OR THE ALUMINUM POLE! THEY CAN BECOME
ELECTRICALLY LIVE AND MAY BE VERY DANGEROUS. Continue to hold the pole saw by the insulated
rear handle or lay it down and away from you in a safe manner. Disconnect the electrical service to the
damaged line or cord before attempting to free the bar and chain from the line or cord. Contact with the
bar, chain, other conductive parts of the pole saw, or live electric cords or lines will result in death by
electrocution or serious injury.
FPO
NOTICE:
• Practice cutting a few small logs to get the “feel” of using your saw before you begin a major sawing operation.
• For second and final cuts (from the top of the limb or branch), hold the bucking spikes against the limb being cut
(fig. 7c). This will help to 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.

LIMBING AND PRUNING (
fig. 8
)
This pole saw is designed for trimming
small branches and limbs up to 8” (20 cm)
in diameter. For best results, observe the
following precautions.
1. Plan the cut carefully. Be aware of the
direction in which the branch will fall.
2. Remove long branches in several stages.
3. Cut lower branches first to allow the top
branches more room to fall.
4. Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance.
5. Keep the tree between you and the chain while limbing. Cut from the side of the tree opposite the
branch you are cutting.
6. Do not make a flush cut next to the main limb or trunk until you have cut off much of limb to reduce
the weight.
7. To prevent electrocution, do not operate within 50’ (15 m) of overhead electrical lines.
8. Keep bystanders at least 50’ (15 m) away.

MAINTENANCE
CLEANING
1. After each use, clean debris from the chain and guide bar with a soft brush. Wipe the pole saw surface with
a clean cloth moistened with a mild soap solution.
2. Remove the side cover, and then use a soft brush to remove debris from the guide bar, saw chain, sprocket
and side cover.
3. Always clean out wood chips, saw dust, and dirt from the guide-bar groove when replacing the saw chain.
ADJUST THE CHAIN TENSION (
fig. 9
)
1. Stop the saw and remove the battery pack before
adjusting the chain tension.
2. Loosen the side-cover knob, insert the wrench into
the chain tensioner to adjust the guide bar and
retighten the side-cover knob securely. Ensure that
the chain will rotate without binding.
• During normal saw operation, the temperature
of the chain will increase. The drive links of
a correctly tensioned warm chain will hang
approximately 3/64’’ (1.3 mm) out of the bar
groove.
• A cold chain is correctly tensioned when there
is no slack on the underside of the guide bar
and the chain is snug, but it can be turned by
hand without binding. The chain must be re-
tensioned whenever the flats on the drive links
do not sit in the bar groove.
MAINTENANCE
NOTICE:
• New chains tend to stretch; check chain tension frequently.
• A chain tensioned while it is warm may be too tight upon cooling. Check the cold tension before next use.

CHAIN MAINTENANCE
SHARPEN THE CUTTERS
(fig. 10a−fig. 10d
)
Be careful to file all cutters (fig. 10a) to the specified
angles and to the same length, as fast cutting can be
obtained only when all cutters are uniform.
1. Remove the battery pack. Wear gloves for protection.
2. Use a 5/32” (4.0 mm) diameter round file and holder
(available separately). Do all of your filing at the
middle position of the guide bar.
3. Keep the file level with the top plate of the tooth. Do
not let the file dip or rock.
4. Keep a correct sharpening angle of 30° between the
file and the saw chain; see figures 10b and 10c.
Always use a file holder (available separately) when
sharpening saw chains by hand. File holders have
markings for the sharpening angle.
5. Using light but firm pressure, stroke towards the front
corner of the tooth. Lift the file away from the steel on
each return stroke.
6. Make 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 filings from the file with a
wire brush (fig. 10d).

TOP-PLATE SHARPENING ANGLES
(
fig. 10e
)
CORRECT 30°- This optimal angle can be obtained
only when the specified files and proper setting are
used. File holders are marked with guide marks to
align the file properly to produce the correct top-plate
angle.
LESS THAN 30°- The tooth is too dull for cutting.
MORE THAN 30°- The edge of the cutting tooth is
feathered and dulls quickly.
SIDE-PLATE ANGLE (
fig. 10f
)
CORRECT 55°- The optimal angle can be produced
automatically if the correct diameter file is used in
the file holder.
HOOK- “Grabs” and dulls quickly. Increases potential
of KICKBACK. Results from using a file with a diam-
eter that is too small, or a file held too 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 a file held
too high.
DEPTH-GAUGE CLEARANCE
(
fig. 10g−fig. 10h
)
1. The depth gauge should be maintained at a
clearance of 1/32” (0.6 mm), as shown in fig. 10g.
Use a depth-gauge tool (available separately) to
check the depth-gauge clearances.
2. Check the depth-gauge clearance every time the
chain is filed.
Use a flat file and a depth-gauge jointer (both
available separately) to lower all gauges uniformly
(fig. 10h). Use a 1/32” (0.6 mm) depth-gauge jointer.
Depth gauges must be adjusted with the flat file in
the same direction that the adjoining cutter was filed
with the round file. Use care not to contact the cutter
face with the flat file when adjusting depth gauges.
