SAFETY INSTRUCTION FOR
PRUNING SAW
WARNING!
Drilling, sawing, sanding or machining wood products
can expose you to wood dust, a substance known to
the State of California to cause cancer. Avoid inhaling
wood dust or use a dust mask or other safeguards for
personal protection. For more information go to
www.P65Warnings.ca.gov/wood.
a) 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.
b) Always hold the pruning saw with your one hand
on the Grip Area (6) and your other hand on the
Secondary Grip Area (3). Holding the pruning saw
improperly increases the risk of personal injury and
should never be done.
c) 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.
d) Wear safety glasses protection. Further protective
equipment for hearing, head, hands, legs and feet
is recommended. Adequate protective clothing will
reduce personal injury by ying debris or accidental
contact with the saw chain.
e) Do not operate a pruning saw in a tree, on a ladder,
from a rooftop, or any unstable support. Operation
of a pruning saw in this manner could result in serious
personal injury.
f) Always keep proper footing and operate the pruning
saw only when standing on xed, secure and level
surface. Slippery or unstable surfaces may cause a
loss of balance or control of the pruning saw.
g) When cutting a limb that is under tension, be alert
for spring back. When the tension in the wood bers
is released, the spring loaded limb may strike the
operator and/or throw the pruning saw out of control.
h) 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.
i) Carry the pruning saw with the pruning saw switched
off and away from your body. When transporting or
storing the pruning saw, always t the guide bar cover.
Proper handling of the pruning saw will reduce the
likelihood of accidental contact with the moving saw
chain.
j) 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.
RESIDUAL RISKS

CAUSES AND OPERATOR PRE-
VENTION OF KICK-BACK
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 pruning saw misuse and/or
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
a) Maintain a rm grip, with thumbs and ngers 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.
6
b) 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.
c) Only use replacement bars and chains specied by
the manufacturer. Incorrect replacement guide bars
and saw chains may cause chain breakage and/or
kickback.
d) Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
WARNING!
The vibration and noise emissions during actual use
of the power tool can differ from the declared value
depending on the ways in which the tool is used
especially what kind of workpiece is processed
dependant on the following examples and other
variations on how the tool is used:
How the tool is used and the materials being cut or
drilled.
The tool being in good condition and well maintained.
The use of the correct accessory for the tool and
ensuring it is sharp and in good condition.
The tightness of the grip on the handles and if any
anti vibration and noise accessories are used.
And the tool is being used as intended by its design
and these instructions.
This tool may cause hand-arm vibration syndrome if
its use is not adequately managed.
WARNING!
To be accurate, an estimation of exposure level in the
actual conditions of use should also take account of
all parts of the operating cycle such as the times when
the tool is switched off and when it is running idle but
not actually doing the job. This may signicantly reduce
the exposure level over the total working period.
Helping to minimise your vibration and noise exposure
risk.
Always use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions
and keep well lubricated (where appropriate).
If the tool is to be used regularly then invest in anti
vibration and noise accessories.
Plan your work schedule to spread any high vibration
tool use across a number of days.

the saw body as possible. Hold saw rmly in place
to avoid possible bouncing or skating (sideways
movement) of saw.
5) Guide the saw using light pressure and do not put
excessive force on the saw, letting the saw do its
work. The motor will overload and can burn out. It
will do the job better and safer at the rate for which
it was intended.
6) Remove the saw from a cut with the saw running at
full speed. Stop the saw by releasing the On/off
Switch. Make sure the chain has stopped before
setting the saw down.
7) Keep practicing on scrap logs in a secure working

4. KICKBACK SAFETY DEVICES ON THIS SAW
This saw has a low-kickback chain and reduced
kickback Guide Bar. Both items reduce the chance of
kickback. However, kickback can still occur with this
saw.
The following steps will reduce the risk of 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.
Use only the low-kickback chain and Guide Bar that
were supplied with this pruning saw or recommended.
Never use a dull or loose chain. Keep chain sharp
with proper tension.
5. HOW TO USE SAW SAFELY
a) Use the pruning saw only with secure footing.
b) Hold the pruning saw at the right-hand side of your
body (See Fig. K).
c) The Chain must be running at full speed before it
makes contact with the wood.
d) Use the Cutting base panel to secure the saw onto
the wood before starting to cut.
e) Use the Cutting base panel as a leverage point while
cutting. (See Fig. L)
To clean the Bar rails
1) Remove Housing-Cover, Bar and Chain.
(see section ASSEMBLY)
2) Using a wire brush, screwdriver or similar tool, clear
the residue from the inner groove of the bar.
(See Fig. R)
3) Make sure to clean oil passages thoroughly.
Conditions which require Chain and Guide Bar
maintenance:
Saw cuts to one side or at an angle.
Saw has to be forced through the cut.
Inadequate supply of oil to the bar and chain.
Check the condition of the Guide Bar each time the
chain is sharpened. A worn Guide Bar will damage the
chain and make cutting difcult.
After each use, remove the battery pack, clean all
sawdust from the Guide Bar and sprocket hole.
When rail top is uneven, use a at le to restore
square edges and sides.
Replace the Guide Bar when the groove is worn, the
Guide Bar is bent or cracked, or when excess heating
or burring of the rails occurs. If replacement is
necessary, use only the Guide Bar specied for your
saw in the repair parts list or on the decal located on
the electric chain saw.
WARNING!
When cutting a limb that is under tension, use
extreme caution. Be alert for woodspringing back.
When wood tension is released, limb could spring
back and strike operator causing severe injury or
death.
When sawing logs supported on both ends, start the
cut from upper side of the saw(Y) about 1/3 of the
diameter into the log (overbuck) and then nish the
cut (Z) from lower side of the saw, in order to avoid
contact of the electric chain saw with the ground.
When sawing logs supported on only one end, start
the cut from below (Y) about 1/3 of the diameter into
the log (underbuck) and nish the cut from above (Z)
in order to avoid log splitting or jamming of the
electric chain saw.
MAINTENANCE AND STORAGE OF ELECTRIC
CHAIN SAW
1) Remove the battery pack
When not in use
Before moving from one place to another
Before servicing
Before changing accessories or attachments, such
as saw chain and guard
2) Inspect electric chain saw before and after each
use. Check saw closely if guard or other part has
been damaged. Check for any damage that may
affect operator safety or operation of saw. Check
for alignment or binding of moving parts. Check for
broken or damaged parts. Do not use electric chain
saw if damage affects safety or operation. Have
damage repaired by authorized service center.
3) Maintain electric chain saw with care.
Never expose saw to rain or direct moisture.
Keep chain sharp, clean, and lubricated for better
and safer performance.
Follow steps outlined in this manual to sharpen
chain.
Keep handles dry, clean, and free of oil and grease.
4) When servicing, use only identical replacement
parts.
5) When not in use, always store electric chain saw in
a high or locked place, out of children’s reach in a
dry place with Bar and Chain Cover in place.
Bar Maintenance
To maximize bar life, the following bar maintenance is
recommended.
The bar rails that carry the chain should be cleaned
before storing the tool or if the bar or chain appear to
be dirty.
The rails should be cleaned every time the chain is
removed.
Never use the electric chain saw above shoulder
height.

SAW MAINTENANCE
Follow maintenance instructions in this manual. Proper
cleaning of saw and chain and Guide Bar maintenance
can reduce chances of kickback. Inspect and maintain
saw after each use. This will increase the service life of
your saw.
NOTE: Even with proper sharpening, risk of kickback
can increase with each sharpening.
Please note the running direction of the saw chain.
The saw chain icon is shown on housing nearby
Drive sprocket (17).
Use an oiler to oil the saw Chain (12) and the Drive
sprocket (17).
Tighten the saw Chain (12)
Re-tighten the Housing-cover (4) with the
Housing-cover knob (3) on the Housing-cover (4).
Let each new saw chain break-in first!
When attaching the saw chain, observe the running
direction!
SHARPENING SAW CHAIN
WARNING:
Remove the battery pack before servicing. Severe
injury or death could occur from electrical shock
or body contact with moving chain. Cutting edges
on chain are sharp. Use protective gloves when
handling chain. Keep chain sharp. Your saw will cut
faster and more safely. A dull chain will cause undue
sprocket, Guide Bar, chain, and motor wear. If you
must force chain into wood and cutting creates only
sawdust with few large chips, chain is dull.
INSTRUCTIONS CONCERNING
THE PROPER TECHNIQUES FOR
LIMBING AND CROSS-CUTTING
1). Limbing a tree
Limbing is removing the branches from a fallen tree.
When limbing leave larger lower limbs to support the
log off the ground. Remove the small limbs in one cut
as illustrated in Figure 1. Branches under tension
should be cut from the bottom up to avoid binding
the electric chain saw.
2). Bucking a log
Bucking is cutting a log into lengths. It is important to
make sure your footing is firm and your weight is
evenly distributed on both feet. When possible, the log
should be raised and supported by the use of limbs,
logs or chocks. Follow the simple directions for easy
cutting.
When the log is supported along its entire length as
illustrated in Figure 2, it is cut from the top (overbuck),
avoid contacting ground as this will greatly reduce the
chain sharpness.
Replacing Chain
Replace chain when cutters are too worn to sharpen
or when chain stops. Only use replacement chain
noted in this manual.
Only handle the saw chain with gloves and remove
the battery first!
Inspect the saw chain and the guide bar for damage
or signs of wear.
Never put a new saw chain on a worn guide bar.
Unscrew the Housing-cover knob (3)
counter-clockwise in order to remove the
Housing-cover (4).
Unscrew the Fastening bar bolt（16） to release
saw Chain (12).
Remove the old saw Chain (12).
Round the new saw chain over the Drive sprocket
(17) and Guide bar (13).
To clean the Bar rails
1) Remove Housing-Cover, Bar and Chain.
(see section ASSEMBLY)
2) Using a wire brush, screwdriver or similar tool, clear
the residue from the inner groove of the bar.
(See Fig. R)
3) Make sure to clean oil passages thoroughly.

When the log is supported on one end, as illustrated
in Figure 3, cut 1/3 the diameter from the underside
(underbuck) (1). Then make the finished cut by
overbucking (2) to meet the first cut.
When the log is supported on both ends, as
illustrated in Figure 4, cut 1/3 the diameter from the
top overbuck) (1). Then make the finished cut by
underbucking (2) the lower 2/3 to meet the first cut.
When bucking on a slope always stand on the uphill
side of the log, as illustrated in Figure 5. When
“cutting through”, to maintain complete control
release the cutting pressure near the end of the cut
without relaxing your grip on the electric chain saw
handles. Don’t let the chain contact the ground. After
completing the cut, wait for the saw chain to stop
before you move the electric chain saw. Always stop
the motor before moving from tree to tree.
