2.8 ELECTRIC CHAINSAW SAFETY WARNINGS
• Use this chain saw only for the purposes it was designed, do not aim the chain saw at
any people or animals.
• Store chain saw indoors – when not in use, chain saw should be stored indoors in dry,
locked-up place – out of reach of children.
• 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 chainsaws may cause entanglement of your
clothing or body with the saw chain.
• 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.
• Hold the power tool by insulated gripping surfaces only, because the saw chain may
contact hidden wiring or its own cord. Saw chains contacting a "live" wire may make
exposed metal parts of the power tool "live" and could give the operator an electric
shock.
• 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.
• Do not operate a chainsaw in a tree. Operation of a chainsaw while up in a tree may
result in personal injury.

• Always keep proper footing and operate the chainsaw only when standing on a xed,
secure and level surface. Slippery or unstable surfaces such as ladders may cause a loss of
balance or control of the chain saw.
• When cutting a branch 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 chainsaw out of control.
• Use extreme caution when cutting bush and saplings.The slender material may catch
the saw chain and be whipped toward you or pull you o balance.
• Carry the chain saw by the front handle with the chainsaw switched o and away from
your body. When transporting or storing the chainsaw always t the guide bar cover.
Proper handling of the chainsaw will reduce the likelihood of accidental contact with the
moving saw chain.
• Follow instructions for lubricating, chain tensioning and changing accessories.
Improperly tensioned o lubricated chain may either break or increase the chance for kick-
back.
• Keep handles dry, clean and free from oil and grease. Greasy, oily handles are slippery
causing loss of control.
• Cut wood only. Do not use chainsaw for purposes not intended. For example: do not
use chainsaw for cutting plastic, masonry or non-wood building materials. Use of the
chainsaw for operations dierent than intended could result in a hazardous situation.
• It is recommended that rst-time users should, as a minimum practice, cut logs on a
saw-horse or cradle.

4.2 INSTALLATION
Assemble the guide bar and the saw chain : illustration 2.1 to 2.9
1. Place the saw body on a rm and level surface.
2. Rotate the clamp nut to remove the cover from the saw’s body.
3. Rotate the locking pin, let the tensioning bolt at the proposal position.
4. With the help of protective gloves, wrap the saw chain around the guide bar, making sure that the
teeth are aimed in the direction of rotation. The chain should be properly set in the slot running along
the entire outside edge of the guide bar.
5. Place the saw chain around the sprocket while lining up the slot in the guide bar with the internal bolt
at the base of the saw and the tensioning bolt in the guide bar’s pin hole. The chain tensioning pin may
need adjustment to properly align with the hole in the guide bar. Use the chain tensioning wheel to
adjust its location until it ts in the guide bar.
6. Turn the chain tensioning wheel to preliminarily tighten the guide bar enough that it stays in place.
While holding the bar still, place the cover back onto the saw. Make sure the tab properly lines up with
the slot on the body of the saw. Lock the cover in place with the lock screw by turning it clockwise until
it engages.
Tensioning the chain : illustration 2.5 and 2.9
Rotating the tension screw upwards increases the tension while rotating it downwards decreases tension.
A properly tensioned chain should have no sag and should only be able to be pulled 2-3 mm away from
the chain bar of the saw.
Note: The saw chain must be tensioned properly in order to
ensure safe operation.
The chain tension is optimal if the saw chain can be lifted 3 mm from the center of the guide bar. Since
the saw chain heats up during operation, its length can therefore uctuate. Check the chain tension
every 10 minutes of operation and adjust as necessary, particularly for new saw chains. Slacken the saw
chain after the work is completed since it shortens when cooling down. In doing so, you can elongate the
chain’s life and prevent damage.
4.3 PREPARATION
Before each use, check the following items to ensure safe working conditions.
Chain saw:
Before beginning work, inspect the chain saw for damage to the housing, the saw chain, the guide bar
and the power cord. Never use an obviously damaged machine.
Chain oil:
Check the ll level of the oil tank. Also check whether there is sucient oil available while working. Never
operate the saw if there is no oil or the oil level has dropped below the minimum oil level mark, in order
to prevent damage to the chain saw. On average, an oil lling is sucient for approximately 10 minutes
of cutting operation (depending the duration of pauses and the density of the work piece).

15
RU
KZ
EN
Saw chain:
Check the tension of the saw and the condition of the saw. The sharper the saw chain is, the easier and
more manageable operations will be. The same applies to chain tension. Check the tension every 10
minutes of operation to maximise safety. New saw chains in particular are subject to changes due to the
heat created by operation.
Safety equipment and protective clothing:
Make absolutely sure to wear the appropriate close-tting protective clothing such as protective pants,
gloves and safety shoes. Wear a safety helmet with integrated hearing protection and a face guard to
provide protection against falling and recoiling branches. Do secure long hair so that it is above shoulder
level. Use the following safety clothing and protective equipment when operating the product:
- Helmet with visor and neck guard
- Hearing protectors
- Breathing mask
- Gloves with approved saw protection
- Protective leggings with approved saw protection
- Steel toe cap boots with approved saw protection
- First aid kit in case of injury.
Filling the auto oil system : illustrations 3.3 and 3.4
CAUTION! The chain saw is NOT supplied lled with oil. It is essential to ll with oil before use. Never
operate the chain saw without chain oil or at an empty oil tank level, as this will result in extensive
damage to the product. Chain life and cutting capacity depends on optimum lubrication. Therefore, the
chain is automatically oiled during operation via the oil outlet. This chain saw features an auto-oiling
system to keep the chain and guide bar properly lubricated. The oil level indicator shows the remaining
oil in the chainsaw. If the oil level decreases to below one quarter capacity, rell it with the proper bar
and chain oil. To ll the oil reservoir:
1. Remove the oil cap. Fill the reservoir with bar and chain oil until the oil level has reached full capacity.
2. Put the oil cap back on. Make sure to check the oil level after every 10 minutes of use. Unplug the
chain saw before checking oil levels or lling the oil reservoir.
CAUTION ! To prevent oil leakage, ensure machine is left in a
horizontal position (oil ller cap upright) when not in use.
Use only the recommended oil to avoid damage to the
chain saw. Never use recycled/old oil.

4.6 CUTTING TIPS
Kickback : Illustration 4.2
Reactive forces may occur any time the chain is rotating. Reactive forces can cause serious personal
injury. The powerful force used to cut wood can be reversed and work against the operator. If the rotating
saw chain is suddenly and signicantly slowed or stopped by contact with any solid abject such as a log
or branch or is pinched, the reactive forces may occur instantly. These reactive forces may result in loss of
control, which, in turn, may cause serious or fatal injury. An understanding of the causes of these reactive
forces may help you avoid the element of surprise and loss of control. Surprise contributes to accidents.
Rotational kickback can happen when the upper tip of the guide bar contacts an abject while the chain
is moving. This can cause the chain to dig into the abject and momentarily stop moving. The guide bar is
then kicked up and back toward the operator in a lightning-fast reverse reaction.
Linear kickback can happen when the wood on either side of a cut closes in and pinches the moving saw

18
RU
KZ
EN
chain a long the top of the guide bar. This can cause the chain to instantly stop. The chain force is then
reversed, causing the saw to move in the opposite direction, sending the saw straight back toward 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. Many factors inuence the
occurrence and force of the kickback reaction. These include saw chain speed, the speed at which the bar
and saw chain contact the abject, the angle of contact, the condition of the saw chain and other factors.
How to avoid kickback
1 ) Hold the chain saw rmly with both hands and maintain a secure grip. Don't let go of the chain saw.
2 ) Be aware of the location of the guide bar nose at all times. Never let the nose of the guide bar contact
any abject. Do not cut limbs with the nose of the guide bar. Be especially careful near wire fences and
when cutting small, tough limbs, small size brush and saplings which may easily catch the saw chain.
3 ) Don't overreach. Don't cut above shoulder height. Do not attempt to plunge cut if you are not
experienced with these cutting techniques.
4 ) Begin cutting and continue at full throttle. Cut only one log at a time.
5 ) Use extreme caution when reentering a previous cut.
6 ) Be alert for shifting of the log or other forces that may cause the cut to close and pinch the saw chain.
7 ) Maintain saw chain properly. Cut with a correctly sharpened, properly tensioned saw chain at all times.
Only use replacement bars and chains specied by the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/ or kickback.
Limbing and bucking Illustration 4.3 to 4.5
Limbing is removing the branches from a fallen tree. Start limbing by leaving the lower limbs to support
the log o the ground. When under-bucking freely hanging limbs, a pinch may result or the limb may fall,
causing loss of control. If a pinch occurs, stop the engine and remove the saw by lifting the limb. Remove
the small limbs in one cut. Branches under tension should be cut from the bottom up to avoid binding
the product. Bucking is cutting a log into lengths. It is important to make sure your footing is rm and
our weight is evenly distributed on bath feet. When possible, the log should be raised and supported
by the use of limbs, logs or chocks. Do not stand on the log. Make sure the log will not roll downhill. If
on a slope, stand on the uphill side of the log. Watch out for rolling logs. Shattered wood should be cut
very carefully. Sharp slivers of wood may be caught and ung in the direction of the operator of the saw.
Don't let the chain contact the ground. Logs under strain: Risk of pinching! Always start relieving cut at
compression side.Then make bucking cut at tension side. If the saw pinches, stop the engine and remove
it from the log. Only properly trained professionals should work in an area where the logs, limbs and roots
are tangled. Drag the logs into a clear area before cutting. Pull out exposed and cleared logs rst.
When the log is supported on one end, cut 1/3 the diameter from the underside (under buck). Then make
the nished cut by over bucking to meet the rst cut. When the log is supported on bath ends, cut 1/3 the
diameter from the top (over buck). Then make the nished cut by under bucking the lower 2/3 to meet
the rst cut. When "cutting through", to maintain complete control release the cutting pressure near the
end of the cut without relaxing your grip on the product handles. Always stop the engine before moving
from tree to tree. If the wood diameter is large enough for you to insert a soft bucking wedge without
touching the chain, you should use the wedge to hold the cut open to prevent pinching.
Always support small logs on a sawing stand or another log while bucking.
Pull in
Pull-in occurs when the saw chain on the bottom of the bar is suddenly stopped when it is pinched,
caught or encounters a foreign object in the wood. The reaction of the saw chain pulls the chain saw

forward and may cause the operator to lose control. Pull-in frequently occurs when the bumper spike of
the chain saw is not held securely against the tree or limb and when the saw chain is not rotating at full
speed before it contacts the wood.
Use extreme caution when cutting small size brush and saplings which may easily catch the saw chain,
be whipped towards you or pull you o balance.
How to avoid pull in :
1) Always start a cut with the saw chain rotating at full speed and the bumper spike in contact with the
wood.
2) The risk of pull-in may also be reduced by using wedges to open the kerf or cut.
Push-back
Push-back occurs when the saw chain on the top of the bar is suddenly stopped when it is pinched,
caught or encounters a foreign object in the wood. The reaction of the saw chain may drive the chain
saw rapidly straight back toward the operator and may cause loss of chain saw control, which, in turn,
may cause serious or fatal injury. Push-back frequently occurs when the top of the bar is used for cutting.
How to avoid push-back :
1 ) Be alert to forces or situations that may cause material to pinch the top of the saw chain. Do not cut
more than one log at a time.
2 ) Do not twist the chain saw when withdrawing the bar from a plunge cut or under-buck cut because
the saw chain can pinch.
