Intended use
The tool is intended for cutting lumbers and logs.
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
only be operated on single-phase AC supply. They are
double-insulated in accordance with European Standard
and can, therefore, also be used from sockets without
earth wire.
For public low-voltage distribution systems of
between 220 V and 250 V.
Switching operations of electric apparatus cause voltage
fluctuations. The operation of this device under unfavorable mains conditions can have adverse effects to the
operation of other equipment. With a mains impedance
equal or less than 0.35 Ohms it can be presumed that
there will be no negative effects. The mains socket used
for this device must be protected with a fuse or protective
circuit breaker having slow tripping characteristics.
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
tion!

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 presented by fall-
ing branches or similar;
• A face mask or goggles;
• Suitable ear protection (ear muffs, custom or mould-
able 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 pro-
duces 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 earthed 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
circuit-breaker with an operating current no higher
than 30 mA.
...................Should the connecting cable be dam-
aged, withdraw the mains plug immediately.
Safe working practices
1. Before starting work, check that the chain saw is
in proper working order and that its condition
9
complies with the safety regulations. Check in particular that:
• The chain brake is working properly;
• The run-down brake is working properly;
• The bar and the sprocket cover are fitted correctly;
• The chain has been sharpened and tensioned in
accordance with the regulations;
• The mains cable and mains plug are undamaged;
Refer to the “CHECKS “section.
2. Always ensure in particular that the extension cable
used is of adequate cross-section (see “SPECIFICATIONS”). When using a cable reel, wind the cable
completely off the reel. When using the saw in the
open air, ensure that the cable employed is intended
for open-air use and is rated accordingly.
3. Do not operate the chain saw in the vicinity of flammable dust or gases, as the motor generates sparks and
presents a risk of explosion.
4. Work only on firm ground and with a good footing. Pay
particular attention to obstacles (e.g. the cable) in the
working area. Take particular care where moisture,
ice, snow, freshly cut wood or bark may make surfaces slippery. Do not stand on ladders or trees when
using the saw.
5. Take particular care when working on sloping ground;
rolling trunks and branches pose a potential hazard.
6. Never cut above shoulder height. (Fig. 1)
7. Hold the chain saw with both hands when switching it
on and using it. Hold the rear handle with your right
hand and the front handle with your left. Hold the handles firmly with your thumbs. The bar and the chain
must not be in contact with any objects when the saw
is switched on.
8. Clean the area to be cut of foreign objects such as
sand, stones, nails, wire, etc. Foreign objects damage
the bar and chain, and can lead to dangerous kickback.
9. Take particular care when cutting in the vicinity of wire
fences. Do nut cut into the fence, as the saw may kick
back.
10. Do not cut into the ground.
11. Cut pieces of wood singly, not in bunches or stacks.
12. Avoid using the saw to cut thin branches and roots, as
these can become entangled in the chain saw. Loss of
balance presents a hazard.
13. Use a secure support (trestle) when cutting sawn timber.
14. Do not use the chain saw to prise off or brush away
pieces of wood and other objects.
15. Guide the chain saw such that no part of your body is
within the extended path of the saw chain. (Fig. 2)
16. When moving around between sawing operations,
apply the chain brake in order to prevent the chain
from being operated unintentionally. Hold the chain
saw by the front handle when carrying it, and do not
keep your finger on the switch. Withdraw the mains
plug when taking breaks or leaving the chain saw
unattended. Leave the chain saw where it cannot
present a hazard.

17. Withdraw the mains plug when taking breaks or leaving the chain saw unattended. Leave the chain saw
where it cannot present a hazard.
Kickback
1. Hazardous kickback may arise during work with the
chain saw. Kickback arises when the tip of the bar (in
particular the upper quarter) comes into contact with
wood or another solid object. This causes the chain
saw to be deflected in the direction of the operator.
(Fig. 3)
2. In order to avoid kickback, observe the following:
• Never begin the cut with the tip of the bar.
• Never use the tip of the bar for cutting. Take particular care when resuming cuts which have already
been started.
• Start the cut with the chain running.
• Always sharpen the chain correctly. In particular, set
the depth gauge to the correct height (refer to
“Sharpening the chain” for details).
• Never saw through several branches at a time.
• When limbing, take care to prevent the bar from
coming into contact with other branches.
• When bucking, keep clear of adjacent trunks.
Always observe the bar tip.
• Use a trestle.
Safety features
1. Always check that the safety features are in working
order before starting work. Do not use the chain saw if
the safety features are not working properly.
- Chain brake:
The chain saw is fitted with a chain brake which brings
the saw chain to a standstill within a fraction of a second. It is activated when the hand guard is pushed forwards. The saw chain then stops within 0.15 s, and
the power supply to the motor is interrupted.
- Run-down brake: (Fig. 4)
The chain saw is equipped with an run down brake
which brings the saw chain to an immediate stop when
the ON/OFF switch is released. This prevents the saw
chain from running on when switched off, and thus
presenting a hazard.
-The front and rear hand guards protect the user
against in jury from pieces of wood which may be
thrown backwards, or a broken saw chain.
- The trigger lockout prevents the chain saw from
being switched on accidentally.
-The chain catcher protects the user against injury
should the chain jump or break.
Transport and storage
................... When the chain saw is not in use or is
being transported, withdraw the mains
plug and fit the scabbard supplied with
the saw. Never carry or transport the
saw with the saw chain running.
1. Carry the chain saw by the front handle only, with the
bar pointing backwards.
