10. Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
11. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
12. Cut wood only. Do not use chain saw for pur-
poses 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.
13. 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 incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
— 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 con-
trolled 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 unin-
tended 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 kickback.
Follow the manufacturer's sharpening
—
and maintenance instructions for the saw
chain. Decreasing the depth gauge height
can lead to increased kickback.
ADDITIONAL SAFETY RULES
1. Read the instruction manual in order to familiarize
yourself with operation of the chain saw.
2. Before using the chain saw for the first time,
arrange to have instruction in its operation. If this
is not possible, at least practice cutting round
timber on a trestle before beginning work.
3. The chain saw must not be used by children or
young persons under 18 years of age. Young
persons over 16 years of age may be exempted
from this restriction if they are undergoing training
under the supervision of an expert.
4. Working with the chain saw requires a high level of
concentration. Do not work with the saw if you are
not feeling fit and well. Carry out all work calmly
and carefully.
5. Never work under the influence of alcohol, drugs
or medication.

Proper use

1. The chain saw is intended solely for cutting wood.
Do not use it for example to cut plastic or porous
concrete.
2. Only use the chain saw for operations described in
this instruction manual. Do not, for example, use it
to trim hedges or for similar purposes.
3. The chain saw must not be used for forestry work,
i.e. for felling and limbing standing timber. The
chain saw cable does not provide the operator with
the mobility and safety required for such work.
4. The chain saw is not intended for commercial use.
5. Do not overload the chain saw.

Personal protective equipment

1. Clothing must be close-fitting, but must not
obstruct mobility.
2. Wear the following protective clothing during work:
• A tested safety helmet, if a hazard is pre-
sented by falling branches or similar;
• A face mask or goggles;
• Suitable ear protection (ear muffs, custom or
mouldable ear plugs). Octave brand analysis
upon request.
• Firm leather safety gloves;
• Long trousers manufactured from strong fabric;
• Protective dungarees of cut-resistant fabric;
• Safety shoes or boots with non-slip soles,
steel toes, and cut-resistant fabric lining;
• A breathing mask, when carrying out work
which produces dust (e.g. sawing dry wood).

Protection against electric shock

The chain saw must not be used in wet
weather or damp environments, as the
electric motor is not waterproof.
1. Only plug the saw into sockets in tested electrical
circuits. Check that the system voltage matches
that on the rating plate. Ensure that a 16 A line
fuse is fitted. Saws used in the open air must
be connected to a residual current-operated cir-
cuit-breaker with an operating current no higher
than 30 mA.
