General Power Tool Safety Warnings
WARNING Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious
injury.
WARNING! Read all safety warnings designated by the symbol and all instructions.
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
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
a) 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.

Power Tool Use and Care
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and
are easier to control.
g) 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.
Safety warnings specific to the product

Safety warnings specific to the product (continued)
c) 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.
d) Do not operate a chain saw in a tree.
Operation of a chain saw while up in a tree may result in personal injury.
e) Always keep proper footing and operate the chain 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 chain saw.
f) 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 chain saw out of control.
g) 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.
h) Carry the chain saw by the front handle with the chain saw switched off and
away from your body. When transporting or storing the chain saw, always fit the
guide bar cover.
Proper handling of the chain saw will reduce the likelihood of accidental contact with the
moving saw chain.
i) Follow instructions for lubricating, chain tensioning and changing accessories.
Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
j) Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
k) Cut wood only. Do not use chain saw for purposes not intended. For example, do not
use chain saw for cutting plastic, masonry or non-wood building materials.
Use of the chain saw for operations different than intended could result in a hazardous
situation.
l) 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 chain
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:

Intended Use
The chain saw is intended for sawing of trees, tree trunks, branches, wooden beams,
planks, etc. Cuts can be sawed with or across the grain. This product is not suitable for
sawing mineral materials.
Preparation
TENSIONING CHAIN
Always check the chain tension before use, after the first cuts and regularly during use, approx.
every 10 minutes. Upon initial operation, new chains can lengthen considerably.
WARNING: Unplug chain saw from power source before adjusting saw chain tension.
WARNING: Cutting edges on chain are sharp. Use protective gloves when handling
chain.
WARNING: Maintain proper chain tension always. A loose chain will increase the risk of
kickback. A loose chain may jump out of guide bar groove. This may injure operator and
damage chain. A loose chain will cause chain, chain bar, and sprocket to wear rapidly.
The chain life of the saw chain mainly depends upon sufficient lubrication and correct
tensioning.
Avoid tensioning the chain if it is hot, as this will cause the chain to become over
tensioned when it cools down.
Please note that the chain tension has been already adjusted ready for use, but kindly
double check if the chain tension is correct. If the chain tension is incorrect, tighten or loosen
the chain and bar to the best position. The machine can be used only on the condition that the
chain tension is correct and the bar is fixed for safety.
The correct chain tension is reached when the chain (8)
8 can be raised approx. 2–3mm from
the chain bar in the centre. This should be done by using one hand in a glove to raise the chain
against the weight of the machine. (See Fig. F)
In case of too tighten chain and bar, please make the below action:
1. Loosen the chain bar by turning the chain locking knob 11 anticlockwise until it is slightly
loose (usually half or one cycle away) (See Fig. F)
2. Loosen the chain tensioning knob 12 anticlockwise a little every time to check the chain
tension until it is correct.
3. When the chain tension is correct, please fix the position of chain tensioning knob 12 by one
hand while turning back the chain locking knob 11 clockwise by another hand to the end.
In case of too loose chain and bar, please make the below action:
1. Loosen the chain bar by turning the chain locking knob 11
11 anticlockwise until it is slightly
loose (usually half or one cycle away) (See Fig. F)
2. Tighten the chain tensioning knob 12 clockwise a little every time to check the chain tension
until it is correct.
3. When the chain tension is correct, please fix the position of chain tensioning knob 12 by one
hand while turning back the chain locking knob 11 clockwise by another hand to the end.

LUBRICATION
IMPORTANT: the chain saw is not supplied with lubricating oil itself but there is one bottle of
lubricating oil(Hydraulic ISO 32) in the box for use. It is essential to fill with oil before use. Never
operate the chain saw without chain oil or at an empty oil tank level (please check the oil level
window on the chain saw), as this will result in extensive damage to the product.
Chain life and cutting capacity depend on optimum lubrication. Therefore, the chain is
automatically oiled during operation via oil outlet.
The oil tank holds 150mI of oil, enough to lubricate the chain for 20-25 minutes of cutting. The
oil tank level can be checked through the chain lubricant tank inspection window provided on
the right side of the saw. (See Fig. G)
The oil supplied is complaint with REACH/Formulated product.

Filling oil tank:
1. Set chain saw on any suitable surface with oil filler cap facing upward.
2. Clean area around the oil filler cap with cloth unscrew cap.
3. Add chain saw oil until reservoir is full, do not overfill. Notice the oil level in the oil reservoir
window on right side of the chain saw.
4. Avoid dirt or debris entering oil tank, refit oil filler cap (4) and tighten.
IMPORTANT: To allow venting of the oil reservoir, small breather channels are provided
between the oil filler cap and the strainer, to prevent leakage ensure machine is left in a
horizontal position (oil filler cap (4) uppermost) when not in use.
It is important to use only the recommended oil to avoid damage to the chain saw. Never
use recycled/old oil. Use of non approved oil will invalidate the warranty.
Checking the automatic oil function:
Check the automatic operation of the chain lubrication by pointing the tip of the switched –
on saw towards a piece of paper laying on the ground, if a patch of oil appears and becomes
larger, then the automatic oil function is working. If there are no traces of oil even though the oil
tank is full, then the automatic oil function is not working.
If the automatic oil function is not working. remove the chain bar and clean out the oil ways of
the chainsaw and chain bar, on reassemble if the chainsaw is still not working, take the chain
saw to an authorized dealer.

Preparation
KICKBACK
Warning: 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 lightning fast 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 injury to user.
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, kickback can still occur with this saw.
Properly install front hand guard, this item can reduce injures from kickback, do not remove
front hand guard, do not replace front hand guard with substitute.
The following steps will reduce the risk of kickback.
Use both hands to grip saw while saw is running. Use firm grip. Thumbs and fingers must wrap
around saw handles.
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 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

Preparation
KICKBACK (continued)
Never try cutting through two logs at same time, only cut one log at a time.
Do not bury 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 re-entering a previous cut.
Use low-kickback chain and guide bar supplied with this chain saw. Only replace these parts
with chains and guide bar listed in this manual.
Never use dull or loose chain, keep chain sharp with proper tension.
Do not hand sharpen chain on automatic chain sharpening (fast sharp) models.
Avoid jamming
Always cut into the compression wood first until the cut starts to close. Always make the
compression cut beneath if the log or limb is suspended from one end, and on top if it is
supported at both ends, cut from the other side towards the compression cut, make a habit of
using a wedge to prevent the compression cut jamming tight on the chainsaw blade.

TIPS FOR CUTTING
4. TIPS FOR CUTTING
-Use the chain saw to cut wood (tree trunks, branches, planks and beams). Never use the saw
for other materials.
-Take care that chain does not come into contact with the ground or foreign materials other than
wood.
-When sawing, do not put pressure on the chain, but let it work with a slight leverage above
wood.
-The best results are obtained when the cutting speed of the chain is not reduced by stress too
intense.
Attention to the end of the cutting when the saw cut and finished it out of alignment, the
weight changes unexpectedly. There is a risk of an accident for the legs and feet.
Do not remove the chainsaw route only when the system is rotating.
-While cutting, always:
-Run the chainsaw motor at full revs, this makes the job safer, as these is less chance of pull-in
or kick-back.
-Position your body to the left of the chainsaw so if it kicks back uncontrollably. It goes over
your right shoulder.
-Keep a firm grip with your left hand on the front handle, with your thumb securely below the
handle. The swivel of your wrist in a kick-back situation will activate the chain brake.
-Make sure the chain is tensioned correctly.
-Observe the size of wood shavings. If they become dusty your chain could need sharpening.
Trimming a tree (pruning)
Trimming a tree (pruning) (See Fig. K)
Warning: Avoid kickback. Kickback can result in severe injury or death.
Warning: Do not operate chain saw while In a tree, on a ladder or any other unstable surface
In any awkward position.You may lose control of saw causing severe injury.
Warning: Do not cut limbs higher than your shoulders.
Trimming a tree is the process of cutting limbs from a living tree, makes sure your footing is firm
keep feet apart. Divide your weight evenly on both feet. Follow directions below to trim a tree.
Make first cut 15 centimeters from tree trunk on underside of limb, use top of guide bar to make
this cut. Cut 1/3 through diameter of limb. Move five to ten centimeters farther out on limb.
Make second cut from above limb. Continue cut until you cut limb off.
Make third cut as close to tree trunk as possible on underside of limb stub. Use top of guide bar
to make this cut. Cut 1/3 through diameter of stub.
Make fourth cut directly above third cut. Cut down to meet third cut, this will remove limb stub.
CAUTION: Seek professional help if facing conditions beyond your ability.

Felling a tree
Felling a tree (See Fig. L)
When bucking and felling operations are being performed by two or more persons at the same
time, the felling operations should be separated from the bucking operation by a distance of at
least twice the height of the tree being felled.
Trees should not be felled in a manner that would endanger any person, strike any utility line
or cause any property damage. If the tree does make contact with any utility line, the company
should be notified immediately.
The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or
slide downhill after it is felled.
An escape path should be planned and cleared as necessary before cuts are started. The
escape path should extend back and diagonally to the rear of the expected line of fall as
illustrated in Figure L.
Before felling is started, consider the natural lean of the tree, the location of larger branches
and the wind direction to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples and wire from the tree.
Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular to the direction of falls as illustrated
in Figure L. Make the lower horizontal notching cut first. This will help to avoid pinching either
the saw chain or the guide bar when the second notch is being made.
Felling back cut (See Fig. M)
Make the felling back cut at least 50 mm higher than the horizontal notching cut as illustrated in
Figure M. Keep the felling back cut parallel to the horizontal notching cut. Make the felling back
cut so enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and
falling in the wrong direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree should begin to fall. If there is any chance that the
tree may not fall in desired direction or it may rock back and bind the saw chain, stop cutting
before the felling back cut is complete and use wedges of wood, plastic or aluminium to open
the cut and drop the tree along the desired line of fall.
When the tree begins to fall remove the chain saw from the cut, stop the motor, put the chain
saw down, then use the retreat path planned. Be alert for overhead limbs falling and watch your
footing.

Limbing a tree
Limbing a tree (See Fig. N )
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 N.
Branches under tension should be cut from the bottom up to avoid binding the chain saw.

Bucking a log
Bucking a log (See Fig. O/Fig. P/Fig. Q/Fig. R )
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 O, it is cut from the top
(overbuck).
When the log is supported on one end, as illustrated in Figure P, cut 1/3 the diameter from the
underside (underbuck). Then make the finished cut by overbucking to meet the first cut.
When the log is supported on both ends, as illustrated in Figure Q, cut 1/3 the diameter from
the top (overbuck). Then make the finished cut by underbucking 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 R.
When “cutting through”, to maintain complete control release the cutting pressure near the end
of the cut without relaxing your grip on the 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 chain saw.
Always stop the motor before moving from tree to tree.

Cleaning saw body
Warning: unplug chain saw from power source before servicing, sever injury or death could
occur from electrical shock or body contact with moving chain.
Warning: cutting edges o chain are sharp, use protective gloves when handling chain.
Warning: cleaning saw body.
Do not submerge saw in any liquids.
Do not use products that contain ammonia, chlorine, or abrasives.
Do not use chlorinated cleaning solvents, carbon tetrachloride, kerosene, or gasoline.
Keep saw body clean, use a soft cloth dampened with a mild soap ad water mixture, wipe saw
body to clean.
Care of guide bar (See Fig. S)
Uneven bar wear causes most guide bar problems, incorrect sharpening of chain cutter and
depth gauge settings often cause this, when bar wears unevenly, it widens guide bar groove,
this causes chain clatter ad river popping. Saw will not cut straight, replaces guide bar if this
occurs.
Inspect guide bar before sharpening chain. A worn or damaged guide bar is unsafe. A worn or
damaged guide bar will damage chain, it will also make cutting harder.

Sharpening the chain
The machine is equipped with PowerSharp® sharpening system from Oregon®,
integrated sharpening system, a fast and easy way to sharpen chain on the saw. It is time to
sharpen the saw chain when cuts take longer or the wood chips become smaller, in extreme
cases turning to saw dust.
IMPORTANT: THE POWERSHARP INTEGRATED SHARPENING SYSTEM IS FOR USE
ONLY WITH POWERSHARPCHAIN.NEVER ATTEMPT TO SHARPEN OTHER CHAIN WITH
THE INTEGRATED SHARPENER.DAMAGE TO THE CHAIN AND SHARPENER WILL
OCCUR.
IMPORTANT: POWERSHARP CHAIN USES UNIQUE TOP-SHARPENING CUTTERS AND
CAN ONLY BE SHARPENED WITH A GENUINE POWERSHARP SHARPENER.
With the saw at full speed, lightly lift the PowerSharp lever for 3 seconds (Fig.U). Spark will be
visible when the cutters are in contact with the sharpening stone. (Fig V)

Sharpening the chain (continued)
Make a test cut to determine if the chain has been sufficiently sharpened. If not, repeat the
sharpening procedure until the chain is sufficiently sharp.
CAUTION: SHARPENING WITH THE POWERSHARP SYSTME PRODUCES LOW ENERGY
SPARKS.
WARNING: POWERSHARP SHOULD NOT BE USED IN THE PRESENCE OF EXPOSED,
EXTREMELY FLAMMABLE MATERIALS SUCH AS GASOLINE AND ACETYLENE.
IMPORTANT: IT IS NORMAL OT SEE A SMLL AMOUNT OF SPARKS AND SMOKE
DURING SHARPENING AS THE CUTTERS CONTACT THE STONE AND FRICTION HEATS
THE CHAIN.
REPLACING THE SHARPENING STONE
The sharpening stone is designed to wear at the same rate as the chain. Always replace to the
stone when replacing the chain, even if appears to have more life.
CAUTION: REPLACE POWERSHARP SAW CHAIN AND THE SHARPENING STONE AT
THE SAME TIME. FAILURE TO DO SO COULD RESULT IN DECREASED PERFORMANCE
OR DAMAGE TO THE CHAIN AND/OR SHARPENING STONE.
IMPORTANT: THE POWERSHARP INTEGRANTED SHARPENING SYSTEM IS FOR USE
ONLY WITH POWERSHARP CHAIN
With the chainsaw off and cool and the power line removed from the power supply, remove the
side cover by removing the side cover knob. Install the new sharpening stone as follows:
Remove the two screws holding the sharpening stone. Remove the stone (See Fig.W)
Make sure the Powersharp lever and surrounding area are free of debris.

WARNING! The vibration emission value during actual use of the power tool can differ from
the declared value depending on the ways in which the tool is used 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 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 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 significantly
reduce the exposure level over the total working period.
Helping to minimize your vibration 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 accessories.
Avoid using tools in temperatures of 100C or less.
Plan your work schedule to spread any high vibration tool use across a number of days.
–That the declared vibration total value has been measured accordance with a standard test
method and may be used for comparing one tool with another;
–That the declared vibration total value may also be used in a preliminary assessment of
exposure.
–That the vibration emission during actual use of the power tool can differ from the
declared total value depending on the ways in which the tool is used; and of the need to identify
safety measures to protect the operator that are based on an estimation of exposure in the
actual conditions of use (taking accounts of all parts of operating cycle such as the times when
the tool is switched off and when it is running idle in addition to the trigger time.)
