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 build-
ing materials. Use of the chain saw for operations
different than intended could result in a hazardous
situation.
12. 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 exclu-
sively 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 incorrect
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 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
kickback.
• Follow the manufacturer's sharpening and main-
tenance instructions for the saw chain. Decreas-
ing 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 run-down brake is working properly;
• The bar and the sprocket cover are fitted cor-
rectly;
• The chain has been sharpened and tensioned in
accordance with the regulations.

14. Do not start the chain saw with the chain cover
being installed on it. Starting the chain saw with
the chain cover being installed on it may cause the
chain cover to thrown out forward resulting in per-
sonal injury and damage to objects around the oper-
ator.
Top handle chainsaw specific safety warnings
1. This chain saw is designed especially for tree
care and surgery. The chain saw is intended to
be used by properly trained persons only.
Observe all instructions, procedures and recom-
mendations from the relevant professional orga-
nization. Otherwise fatal accidents may occur. It
is recommend that always using a rising plat-
form (cherry picker, lift) for sawing in trees. Rap-
pelling 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 equip-
ment for both the operator and the saw.
2. Perform cleaning and maintenance before stor-
age in accordance with the instruction manual.
3. Ensure safe positioning of the chain saw during
car transportation to avoid fuel or chain oil leak-
age, damage to the tool and personal injury.
4. Do not fill the chain oil near fire. Never smoke
when you fill the chain oil.
5. National regulation may restrict the use of the
chain saw.
6. If the equipment gets heavy impact or fall, check
the condition before continuing work. Check the
controls and safety devices for malfunction. If
there is any damage or doubt, ask our autho-
rized service center for the inspection and repair.
7. Hold the saw firmly in place to avoid skating
(skid movement) or bouncing of the saw when
starting a cut.
8. At the end of the cut, be careful to keep your bal-
ance due to the "drop".
9. Take into account the direction and speed of the
014673
wind. Avoid sawdust and chain oil mist.
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 oper-
ation of the chain saw:
– The kind of clothing should be appropriate, i. e. it
should be tight-fitting but not be a hindrance. Do
not wear jewelry or clothing 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 when-
ever working with the chain saw. The protective
helmet is to be checked in regular 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 prevent eye inju-
ries.
– Wear adequate noise protection equipment
(ear muffs, ear plugs, etc.)
