General Power Tool Safety Warnings
Safety warnings
Work area safety
Electrical safety
WARNING! Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, re
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.
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.
a) Power tool plugs must match the socket. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodied plugs and matching sockets will reduce the risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep the cord away from heat, oil, sharp edges or
moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) 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.
f) The use of a residual current device (RCD) when using this tool is
recommended.
Use of an RCD reduces the risk of electric shock.

4
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 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.
Personal safety
a) 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.
b) Use personal protective equipment (PPE). Always wear eye protection.
Protective equipment, such as a dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to a power source and/or battery pack and before picking
up or carrying the tool.
Carrying power tools with your nger on the switch or energising power tools that
have the switch on invites accidents.
d) Remove any adjusting key or spanner before turning the power tool on.
Always check that adjusting keys and spanners are removed from the tool before
operating.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) 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.
g) 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 (continued)
Safety warnings specific to the product
a) Keep all parts of the body away from the saw chain when the chainsaw
is operating. Before you start the chainsaw, make sure the saw chain is not
contacting anything.
A moment of inattention while operating the chainsaw may cause entanglement of
your clothing or body with the saw chain.
b) Always hold the chainsaw with your right hand on the rear handle and your
left hand on the front handle.
Holding the chainsaw with a reversed hand conguration increases the risk of
personal injury and should never be done.
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 ying debris or accidental
contact with the saw chain.
d) Do not operate a chainsaw in a tree.
Operation of a chainsaw while up a tree may result in personal injury.
e) Always keep proper footing and operate the chainsaw only when standing
on a fixed, secure and level surface.
Slippery or unstable surfaces, such as ladders, may cause a loss of balance or
control of the chainsaw.
f) When cutting a limb that is under tension, be alert for spring back.
When the tension in the wood bres is released, the spring-loaded limb may strike
the operator and/or throw the chainsaw 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 chainsaw by the front handle with the power tool switched off and
away from your body. When transporting or storing the chainsaw, always fit
the guide bar cover.
Proper handling of the chainsaw will reduce the likelihood of accidental contact with
the moving saw chain.
i) Follow instructions for lubricating, chain tensioning and changing
accessories.
An improperly tensioned or lubricated chain may either break or increase the
chance for kickback.
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.
General Power Tool Safety Warnings

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 the chainsaw for purposes not intended. For
example, do not use the chainsaw for cutting plastic, masonry or non-wood
building materials.
Use of the chainsaw 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. In some cases, tip
contact 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 chainsaw 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:
m) Maintain a firm grip with thumbs and fingers encircling the chainsaw
handles. With both hands on the saw, 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 chainsaw.

n) Do not overreach and do not cut above shoulder height.
This helps prevent unintended tip contact and enables better control of the chainsaw
in unexpected situations.
o) Only use replacement bars and chains specified by the manufacturer.
Incorrect replacement bars and chains may cause chain breakage and/or kickback.
p) Follow the manufacturer’s sharpening and maintenance instructions for the
saw chain.
Decreasing the depth gauge height can lead to increased kickback.
a) 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.
b) If the replacement of the supply cord is necessary, this has to be done by
the manufacturer or his agent in order to avoid a safety hazard.

Intended Use
Preparation
Tensioning chain
Always check the chain tension before use, after the rst cuts and regularly
during use, approx. every 10 minutes. Upon initial operation, new chains can
lengthen considerably.
WARNING: Unplug the chainsaw from the power source before adjusting
the saw chain tension.
WARNING: Cutting edges on the chain are sharp. Use protective gloves
when handling the chain.
WARNING: Maintain proper chain tension always. A loose chain will
increase the risk of kickback. A loose chain may jump out of the guide
bar groove. This may injure the operator and damage the chain. A loose
chain will cause the chain, chain bar, and sprocket to wear rapidly.
The chain life of the saw chain mainly depends upon sufcient 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.
The chainsaw is intended for sawing trees, tree trunks, branches, wooden beams,
and planks, etc. Cuts can be sawn with or across the grain. This product is not
suitable for sawing mineral materials.
Please note that the chain tension has already been adjusted ready for use, but be
sure to 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 xed for safety.
The correct chain tension is reached when the chain (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 a too tight 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 x the position of the chain tensioning
knob (12) by one hand while turning back the chain locking knob (11) clockwise by
another hand to the end.

13
Preparation
Lubrication
Tensioning chain
(continued)
IMPORTANT: The chainsaw 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 ll with oil before use. Never operate the chainsaw without chain oil or with
an empty oil tank level (please check the oil level window on the chainsaw), 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 an 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 compliant with REACH/Formulated product.
In case of a too loose 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. 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 x the position of the chain tensioning
knob (12) with one hand while turning back the chain locking knob (11) clockwise
with another hand to the end.

Filling the oil tank:
1. Set the chainsaw on any suitable surface with the oil ller cap facing upward.
2. Clean the area around the oil ller cap; using a cloth, unscrew the cap.
3. Add the chainsaw oil until the reservoir is full, do not overll. Notice the oil
level in the oil reservoir window on the right side of the chainsaw.
4. Avoid dirt or debris entering the oil tank, ret the oil ller 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 the 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 chainsaw. 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 airways of the chainsaw and chain bar. On reassembly, if the chainsaw
is still not working, take the chainsaw to an authorised dealer.

15
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 lightning-fast reverse reaction, i.e.
kicking the guide bar up and back towards the operator; or pinching the saw
chain along the top of the guide bar, which 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 the 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, but kickback can still occur with this saw.
Properly install the front hand guard. This item can reduce injures from
kickback. Do not remove the front hand guard; do not replace the front hand
guard with a substitute.
The following steps will reduce the risk of kickback:
- Use both hands to grip the saw while it is running. Use a rm grip. Thumbs
and ngers must wrap around the saw handles.
- Keep all safety items in place on the saw and 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 the saw. This keeps your body from being in
direct line with chain.
- Do not let the guide bar nose touch anything when the chain is moving.

Preparation
Operation
Kickback (continued)
Switching on and off
- Never try cutting through two logs at the same time, only cut one log at a time.
- Do not bury the guide bar nose or try to plunge cut (boring into wood using
guide bar nose).
- Watch for shifting of wood or other forces that may pinch the chain.
- Use extreme caution when re-entering a previous cut.
- Use the low-kickback chain and guide bar supplied with this chainsaw. Only
replace these parts with chains and guide bars listed in this manual.
- Never use a dull or loose chain, and keep the chain sharp with proper tension.
- Do not hand sharpen the chain on automatic chain sharpening (fast sharp)
models.
Avoid jamming
Always cut into the compression wood rst 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, and 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
Trimming a tree (pruning)
4. TIPS FOR CUTTING
- Use the chainsaw to cut wood (tree trunks, branches, planks and beams).
Never use the saw for other materials.
- Take care that the 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: At the end of the cutting process, when the saw cut is
finished and it comes out of alignment, the weight changes unexpectedly.
There is a risk of injury to 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 there's less
chance of pull-in or kickback.
- Position your body to the left of the chainsaw so if it kicks back uncontrollably,
it goes over your right shoulder.
- Keep a rm 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) (See Fig. K)
WARNING! Avoid kickback. Kickback can result in severe injury or death.
WARNING! Do not operate the chainsaw while up a tree, on a ladder or any
other unstable surface, or in any awkward position. You may lose control of the
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. Make sure
your footing is rm, keeping feet apart. Divide your weight evenly on both
feet, creating a strong stance. Follow directions below to trim a tree.
Make the rst cut 15 centimeters from the tree trunk on the underside of the
limb, use the top of the guide bar to make this cut. Cut 1/3 through the diameter
of the limb. Move ve to ten centimeters farther out on the limb.
Make a second cut from above the limb. Continue the cut until you cut the limb
off.

19
Operation
Trimming a tree (pruning) (continued)
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 notied immediately.
The chainsaw 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 rst. This will help
Make a third cut as close to the tree trunk as possible on the underside of the
limb stub. Use the top of the guide bar to make this cut. Cut 1/3 through the
diameter of the stub.
Make a fourth cut directly above the third cut. Cut down to meet the third cut,
this will remove the limb stub.
CAUTION: Seek professional help if facing conditions beyond your ability.
