1). Make sure the chain brake level is disengaged; (See Fig. 1a)
2). Place the chain saw on any suitable flat surface;
3). Plug the unit into the power source;
4). Grasp the front handle with your left hand. Thumb and fingers should encircle the
handle;
5). Grasp the rear handle with your right hand. Thumb and fingers should encircle the
handle;
6). Press the lock-off button with your right thumb, then fully press the switch trigger with
your index finger and hold in this position;
7). While the motor is running, activate the chain brake by rolling your left hand
forward against the chain brake lever; (See Fig. 1b);
8). Chain and motor should stop immediately.
NOTE: The motor will not start if the chain brake lever is in the engaged position.
WARNING: To reduce the time of exposure to vibration and noise, it is preferable to use
the machine with frequent breaks, and limiting the duration of continuous work.
WARNING: The vibration level during actual use of the chainsaw may differ from the
declared depending on what material is being cut with different factors of stem diameter 
density and fibre composition to name a few.
The chain brake is a safety mechanism activated through the front hand guard. When
kickback occurs, the chain stops immediately through inertia. The following function
check should be carried out at regular intervals. The purpose of the chain brake testing
is to reduce the possibility of injury due to kickback.
2.3.1 CHAIN BRAKE.
WARNING! If the chain and motor fail to stop when the chain brake is engaged,Stop
using immediately take the saw to the nearest authorised dealer. Do not use the saw if
the chain brake is not in proper working order.
CAUTION! The chain brake lever should not be used for starting and stopping the
saw during normal operation.

2.3.2 OVERLOAD PROTECTION.
2.3.3 KICKBACK. (See Fig. 2)
To avoid kickback:
- Saw with guide bar at a flat angle
- Never work with a loose, widely stretched or the heavily worn out chain:
- Ensure chain is sharpened correctly:
- Never saw above shoulder height:
- Never work with the tip of the guide bar:
- Always hold the chain saw firmly with both hands
- Always use a low kickback chain:
- Apply the metal gripping teeth for leverage:
- Ensure correct chain tension:
2.3.4 GENERAL BEHAVIOR.
Always hold the chain saw firmly with both hands. Front grip with the left hand and rear
grip with the right hand. Fully grip both handles at all times during operation. Never
operate the chainsaw using only one hand. Ensure the power cord is located to the rear,
away from the chain and wood and so positioned that it will not be caught on branches
or material during cutting. (See Fig.2)
Overloading (e.g. blocking of the cutting blade, blade teeth jammed) causes the
machine to stop and the overload protector will be activated.
Kickback is the sudden backward/upward motion of the chain saw, occurring when the
chain (at the tip of the chain bar) comes in contact with a log or wood, or when the chain
becomes jammed.
When kickback occurs the chain saw reacts unpredictably and can cause severe injuries
to the operator or bystanders.
Particular attention must be given when sawing sideward, slanted or during length cuts,
as the spiked bumper usually can not be applied.
Use the chainsaw only with secure footing. Hold the chainsaw at the right-hand side of
your body. (See Fig.3a)

Instruction Manual / 11
- Reset the gripping teeth at a low point when sawing thicker logs by pulling the chain
saw slightly backwards until the gripping teeth release, and reposition at lower level
to continue sawing. Do not remove the saw completely from the wood.
- Do not force the chain while cutting, let the chain do the work, using the gripping
teeth to apply minimal leverage pressure.
- Do not operate the chainsaw with arms fully extended or attempt to saw areas which
are difficult to reach, or on a ladder. Never use the chainsaw above shoulder height.
(See Fig.3c)
- Sawing is optimised when the chain speed remains steady during cutting.
- Beware when reaching the end of the cut. The weight of the saw may change
unexpectedly as it cuts free from the wood. Accidents can occur to your legs and
feet. Always remove the saw from a wood cut while the saw is running.
2.3.5 CUTTING LOGS.
Observe the following safety instructions:
- Support logs so that the face sides at the cut do not
close in against each other, which would result in the
chain being jammed or pinched. (See Fig.3a, Fig.4)
The chain must be running at full speed before it makes contact with the wood. Use the
metal gripping teeth to secure the saw onto the wood before starting to cut. Use the
gripping teeth (12) as a leverage point while cutting. (See Fig.3b)
3b
3c

- Position and set short logs safety prior to sawing. Only saw wood or wooden objects.
When sawing, always take care to avoid hitting stones, nails, etc, as these could
be thrown up or cause damage to the chain or serious injury to the operator or
bystanders.
- Keep a running saw clear of wire fencing or the ground. Use of the saw to thin out
branches or bushes is not approved.
- Length cuts must be carried out with care, as leverage with the gripping teeth (17) is
not possible. Saw at a flat angle to avoid kickback.
- When working on a slope, operate above or to the side of the trunk or laying tree.
- Be careful not to trip over tree stumps, branches, roots, etc.
Should the chain touch earth/soil the chain will become instantly blunt.
- Secure work area. ensure no persons or animals are in the vicinity of the falling tree.
Never attempt to free a jammed saw with the motor running. Use tree wedges to
free chain and guide bar.
When cutting and felling operations are being performed by two or more persons, at
the same time, the felling operations should be separated from the cutting 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 ideally diagonally to the rear of the expected line
of fall.
- 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 (x-w)1/3 the diameter of the tree, perpendicular to
the direction of falls as make the lower horizontal notching cut. This will help to avoid
pinching either the saw chain or the guide bar when the second notch is being made.
- Felling back cut: make the felling back cut (Y)at least 50 mm higher than the
2.3.6 CUTTING WOOD UNDER TENSION. (See Fig.4)
There is a high risk of accidents when sawing logs, branches or stems under tension.
Be extremely careful. Leave saw jobs like these to professionals. When sawing logs
supported on both ends, start the cut from above (Y) about 1/3 of the diameter into the
log and then finish the cut (Z) from below, in order to avoid contact of the 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 and nish the cut from above (Z) in order to avoid
log splitting or jamming of the chain saw.
2.3.7 GENERAL CUTTING INSTRUCTIONS.
1). Felling trees. (See Fig. 5)
Always wear a hard-hat with visor to protect your head against falling branches. The
chainsaw can only be used to fell trees smaller in diameter than the length of the guide bar.

2). De-limbing a tree. (See Fig. 6)
De-limbing is removing the branches from a fallen tree. When de-limbing leave larger
lower limbs to support the log off the ground. Remove the small limbs in one cut as
illustrated. Branches under tension should be cut from the bottom up to avoid binding the
chain saw.
horizontal notching cut. 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 aluminum 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 cutting, stop the motor,
put the chainsaw down, and then use the retreat path planned. Be alert for overhead
limbs/branches falling and watch your footing. To complete the felling operation,
drive a wedge (Z) into the horizontal cut.
- Beware of falling branches when the tree starts to move.

3). 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 as illustrated, it is cut from the top
(overbuck). (See Fig. 7a)
When the log is supported on one end, as illustrated, cut 1/3 the diameter from the
underside (underbuck). Then make the finished cut by overbucking to meet the first cut.
(See Fig. 7b)
When the log is supported on both ends, as illustrated, 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.
(See Fig. 7c)

7b
7c

When bucking on a slope always stand on the uphill side of the log, as illustrated. 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. (See Fig. 7d)
2.4.After using a chainsaw
• Always unplug the unit from the power supply before performing any service or
control.
•Only carry the chainsaw when it is unplugged and completely stopped. Hold
the machine by the front handle, with the guide bar and chain turned back and
with the protective scabbard in place
• Always follow the instructions provided for maintenance. After each use, check the
operation of safety devices, setting, tension and condition of parts. Maintain unit.
Replace worn or damaged parts.
•Repairs on the electric chainsaw should only be carried out by an approved Cobra Service Agent.
For safety reasons, use only original spare parts approved by Cobra Garden.
•Keep the chainsaw clean and always store in a dry place with the protective
scabbard in place. Store power tools in a place out of reach of children.
•Keep this manual safe and refer to it when using the machine or servicing.

Your chainsaw is supplied with an SDS system for quick
assembly and easy adjustment of the chain tension. The
adjustable outside ring (13) adjusts the tension of the
saw chain and the locking knob (14) tension the bar. (See
Fig.8)
1). Unpack all parts carefully.
2). Place the chain saw on any suitable flat surface.
3). Pull back on the chain brake lever to deactivate the
chain brake.
4). Unscrew counter-clockwise the locking knob of the SDS
to remove the side cover. (See Fig.9)
5). Spread the saw chain out with the cutting edges (A) of the chain pointing in the
direction of rotation. Slide the saw chain into the slot around the chain bar.
Ensure chain is in the correct running direction. (See Fig.10a, 10b)
3.1.1 Mounting guide bar and chain
Attention: Wear gloves when handling the saw to prevent accidents relating to the the
chain and bar spikes that are extremely sharp.
Attention: Do not plug the machine in to the power source during assembly.
WARNING! Assembly methods according to the type of your machine, so please
take care to refer to the illustrations and machine type marked on the label. Take great
care when assembling to ensure this is performed correctly.

7). Fit side cover, ensure that the bar fastening bolt fits into
the screw thread of the locking knob (14). Screw
on the locking knob to tighten the side cover. (See Fig.
12).
6). Mount the bar on the bar fastening bolt (16), fit the
chain onto the drive sprocket (17) and guide the guide
bar, so that the bar fastening bolt and the two guide
pins (B) fit into the keyway of the guide bar. (See Fig.
11)
8). The chain is not yet tensioned now. Tensioning the chain applies as described under
“TENSIONING CHAIN”. After running the chain saw around 1 hour, adjust the chain
tension to 2mm by applying 9N of torque.
3.1.2 TENSIONING CHAIN
-Always check the chain tension before use, after the first cuts and regularly during
use, approx. every 5 cuts.
-Upon initial operation, new chains can lengthen considerably. This is normal during
the break-in period, and the interval between future adjustments will lengthen quickly.
WARNING: Unplug the chain saw 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. The chain will be hot after cutting
material.
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.
12
11

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.
WARNING! Tensioning the chain too tightly will overload the motor and
cause damage, insufficient tension can provoke chain derailing, whereas
a chain tightened correctly provides the best cutting characteristics and
prolonged work life.
Check the tension regularly because the chain length tends to stretch with use
(especially when the chain is new; after the first assembly, the chain tension must be
checked after 5 minutes of machine operation); in any case do not tighten the chain
immediately after use, but wait until it cools down.
In cases where the loosened chain needs to be adjusted, always unscrew the adjustable
outside ring before adjusting the chain tensioning screw/knob; adjust the tension and
tighten the bar retaining the nut/knob accordingly.
1). Place the chain saw on any suitable flat surface. Screw adjustable outside ring
clockwise until the SDS system is screwed tightly. The
correct chain tension will be reached automatically. The
ratchet mechanism prevents the chain tension from
loosening. (See Fig. 13)
2). The correct chain tension is reached when the saw chain (24) can be raised approx.
2-3 mm from the guide bar in the centre. This should be
done by using one hand to raise the saw chain against
the weight of the machine. (See Fig.14)
3). When the saw chain loosens, unscrew the adjustable outside ring absolutely and then
screw on the side cover with the locking knob tightly again.

WARNING! The chain saw is not supplied lled with oil. It is essential to ll
with oil before use. Never operate the chainsaw without chain oil or at an
empty oil tank level, as this will result in extensive damage to the chainsaw.
Never starve the bar and chain of lubrication oil. Running the saw dry or with
too little oil will decrease cutting efficiency, shorten chain saw life, and
cause rapid wear of the chain and excessive wear of the bar from
overheating. Too little is evidenced by smoke or bar discoloration.
WARNING! 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 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.
CAUTION! The oil tank level should be frequently checked during operation
to avoid starving the bar and chain of lubrication.
Adequate lubrication of the saw chain during cutting operations is essential to minimize
friction with the guide bar. your chainsaw is equipped with an automatic oiler system. The
oiler automatically delivers the proper amount of oil to the bar and chain.
The oil tank holds 210mI 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 (10)
provided on the right side of the saw. (See Fig.15)
3.1.3 CHAIN AND BAR LUBRICATIPON
Filling oil tank:
1). Set the chain saw on any suitable surface with the oil filler cap (C) facing
upward. 2). Clean the area around the oil filler cap with the cloth.
3). Add chain saw oil until the reservoir is full.
4). Avoid dirt or debris entering the oil tank, refit the oil filler cap and tighten.
NOTE: Your chain saw is equipped with an Automatic Oiler system and is the only source
of lubrication for the bar and saw chain.

3.2 Using the chainsaw
Before use, make sure that you have the correct safety equipment and that the plug
and lead are in good working order. Also check the status of the chain and the chain
guide and the fixing system. If necessary, replace or repair defective components.
Use only original parts approved by Cobra Garden.
3.2.1 Starting chainsaw
WARNING: Never work with a guide bar and a damaged or excessively worn
chain as this may cause personal injury.
WARNING! Check the voltage and current supply. The voltage and current
supply must comply with the ratings on the type plate.
WARNING! Ensure the extension cord is of the proper size and type for your
saw (≥1.5mm2)
1). Make sure the chain brake lever (1) is disengaged. The motor will not start if the
chain brake is in the engaged position. Disengage the chain brake lever by
pulling backward toward the front handle. (See Fig. 16).
2). Grip the product with both hands, left hand holding the front handle (do not hold chain
brake) and the right hand holding the rear handle. Press the lock-off button (5), then
fully press the switch trigger (6) and hold in this position. The lock-off button can now
be released now. (See Fig. 17a, 17b).
NOTE: It is not necessary to maintain pressure on the lock-off button once the switch
trigger is squeezed and the motor is running. The lock-off button is a safety device to
avoid accidental starting.
