Noise Information
Measured sound values determined according to ISO 22868.
The noise figures quoted are emission levels and are not
necessarily safe working levels. Whilst there is a correlation
between the emission and exposure levels, this cannot be used
reliably to determine whether or not further precautions are
required. Factors that influence the actual level of exposure of
work-force include the characteristics of the work room, the other
sources of noise, etc. i.e. the number of machines and other
adjacent processes, and the length of time for which an operator
is exposed to the noise. Also the permissible exposure level can
vary from country. This information, however, will enable the user
of the machine to make a better evaluation of the hazard and risk.
Wear hearing protection
Vibration total values (triax vector sum) determined according to
ISO 22867:

5
The vibration emission level given in this information sheet has
been measured in accordance with a standardized test given in
ISO 22867:2003 and may be used to
compare one tool with another.
It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main
applications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained, the
vibration emission may differ. This may significantly increase the
exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or when it
is running but not actually doing the job. This may significantly
reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from
the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organization of work patterns.

SPECIAL SAFETY WARNINGS FOR THE TOOL

12
Keep all parts of the body away from the saw chain when the chain saw is
operating.
Before you start the chain saw, make sure the saw chain is not
contacting anything.
A moment of inattention while operating chain saws may cause entanglement
of your clothing or body with the saw chain.
Always hold the chain saw with your right hand on the rear handle and
your left hand on the front handle. Holding the chain saw with a reversed
hand configuration increases the risk of personal injury and should never be
done.
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.
Do not operate a chain saw in a tree. Operation of a chain saw while up in a
tree may result in personal injury.
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.
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.
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.
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.
Follow instructions for lubricating, chain tensioning and changing
accessories.
Improperly tensioned or lubricated chain may either break or increase the
chance for kickback.

13
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 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.
KICKBACK SAFETY PRECAUTIONS FOR CHAIN SAW USERS
•How to read symbols and colors (Fig. 1)
Fig. 1
Warning: RED Used to warn that an unsafe procedure should not
be performed.
WARNING
1. Avoid bar nose contact
2. Beware of kick back.
3. Do not attempt to hold saw with one hand
4. Hold saw properly with both hands.
DANGER! BEWARE 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 lightning fast reverse
reaction, kicking the guide bar up and back towards the operator.

14
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.
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:
Fig, 2A Fig. 2B
BEWARE OF: ROTATIONAL KICKBACK (Fig. 2A)
A = Kickback path
B = Kickback reaction zone
THE PUSH (PINCH KICKBACK) AND PULL REACTIONS (Fig. 2B)
A = Pull
B = Solid objects
C = Push
Maintain a firm grip, with thumbs and fingers encircling the chain 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 chain saw.
Do not overreach and do not cut above shoulder height. This helps prevent
unintended tip contact and enables better control of the chain saw in
unexpected situations.
Only use replacement bars and chains specified by the manufacturer.
Incorrect replacement bars and chains may cause chain breakage and/or

15
kickback.
Follow the manufacturer’s sharpening and maintenance instructions for
the saw chain. Decreasing the depth gauge height can lead to increased
kickback.
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.
ASSEMBLY

WARNING!
Always carry out a test run before starting work and after every
tool change! Always ensure that the tools are in good condition,
correctly mounted and able to turn freely. The trial run should be
at last 30 sec.
Adjusting chain tension
WARNING!
The saw chain has very sharp edges. Use protective gloves for
safety.
Saw chain tensioning
1) Always check the saw chain tension before use, after the first cuts and
regularly during use, approx. every five 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.
2) Lift up the tip of the guide bar (13) and keep it there as you adjust the

18
tension (Fig. 10).
Fig. 10
3) Turn the tension screw (22a) until the chain ‘tie straps’ are just touching the
bottom edge of the guide bar (13) (Fig. 11, 12).
Fig. 11 Fig. 12
4) Lift up the tip of the guide bar (13) and tighten the rear retaining nut (16)
first followed by the front retaining nut (16) (Fig. 9).
5) By hand, pull the saw chain (14) along the top of the guide bar (13) from
one end to the other, several times. The chain should feel tight but still
move freely.
Tension test
Check the chain tension using one hand to lift the saw chain (14) against the
weight of the product. The correct chain tension is achieved when the saw
chain can be lifted by approximately 2 - 4 mm from the guide bar (13) in the
centre (Fig. 13, 14).
