(cordless) power tool.
Cordless Chain saw safety warnings
1. 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.
2. Always hold the chain saw with your right
hand on the top handle and your left hand on
the front handle. Holding the chain saw with a

3. Hold the power tool by insulated gripping
surfaces only, because the saw chain may con-
tact hidden wiring. Saw chains contacting a "live"
wire may make exposed metal parts of the power
tool "live" and could give the operator an electric
shock.
4. Wear safety glasses and hearing protection.
Further protective equipment for head, hands,
legs and feet is recommended. Adequate protec-

9. Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
10. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
11. 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

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

Do not let go of the chain saw.

• Follow the manufacturer’s sharpening and

Decreasing the depth gauge height can lead
to increased kickback.
13. Before starting work, check that the chain
saw is in proper working order and that its
condition complies with the safety regulations.
Check in particular that:
• The chain brake is working properly;
• The run-down brake is working properly;

Observe all instructions, procedures and rec-
ommendations from the relevant professional
organization. Otherwise fatal accidents may
occur. It is recommend that always using a
rising platform (cherry picker, lift) for sawing
in trees. Rappelling techniques are extremely
dangerous and require special training. The
operators must be trained to become familiar
with safety equipment usage and climbing
techniques. Always use the appropriate belts,
ropes and carabiners when working in trees.
Always use restraining equipment for both the
operator and the saw.
2. Perform cleaning and maintenance before
storage in accordance with the instruction
manual.
3. Ensure safe positioning of the chain saw
during car transportation to avoid fuel or chain
oil leakage, damage to the tool and personal
injury.
4. Regularly check the functionality of chain
brake.

7. If the equipment gets heavy impact or fall,
check the condition before continuing work.
Check the controls and safety devices for mal-

Protective equipment
1. In order to avoid head, eye, hand or foot
injuries as well as to protect your hearing the
following protective equipment must be used
during operation of the chain saw:

which could become entangled with bushes
or shrubs. If you have long hair, always wear
a hairnet!
— It is necessary to wear a protective helmet
whenever working with the chain saw. The
protective helmet is to be checked in regu-
lar intervals for damage and is to be replaced
after 5 years at the latest. Use only approved
protective helmets.
— The face shield of the protective helmet (or
the goggles) protects against sawdust and
wood chips. During operation of the chain
saw always wear a goggle or a face shield to

— The protective jacket consists of 22 layers
of nylon and protects the operator against
cuts. It is always to be worn when working
from elevated platforms (cherry pickers,
lifts), from platforms mounted on ladders or
when climbing with ropes.
— The protective brace and bib overall is
made of a nylon fabric with 22 layers and
protects against cuts. We strongly recom-
mend its use.
— Protective gloves made of thick leather are
part of the prescribed equipment and must
always be worn during operation of the chain
saw.
— During operation of the chain saw safety
shoes or safety boots

3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
4. If electrolyte gets into your eyes, rinse them
out with clear water and seek medical atten-
tion right away. It may result in loss of your
eyesight.
5. Do not short the battery cartridge:
(1) Do not touch the terminals with any con-
ductive material.
(2) Avoid storing battery cartridge in a con-
tainer with other metal objects such as
nails, coins, etc.

take on heat which can cause burns or low
temperature burns. Pay attention to the han-
dling of hot battery cartridges.
15. Do not touch the terminal of the tool imme-
diately after use as it may get hot enough to
cause burns.

Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.
2. Never recharge a fully charged battery car-
tridge. Overcharging shortens the battery
service life.
3. Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4. When not using the battery cartridge, remove
it from the tool or the charger.
5. Charge the battery cartridge if you do not use
it for a long period (more than six months).

CAUTION: Do not touch the saw chain with
bare hands. Always wear gloves when handling
the saw chain.
Removing or installing saw chain
CAUTION: The saw chain and the guide bar are
still hot just after the operation. Let them cool down
enough before carrying out any work on the tool.
CAUTION: Carry out the procedure of install-
ing or removing saw chain in a clean place free
from sawdust and the like.
To install the saw chain, perform the following steps:
1. Check the direction of the saw chain. Match the
direction of the saw chain with that of the mark on the
chain saw body.
2. Fit one end of the saw chain on the top of the
guide bar.
3. Fit the other end of the saw chain around the
sprocket, then attach the guide bar to the chain saw
body, aligning the hole on the guide bar with the pin on
the chain saw body.

between the depth gauge (round nose) and the
