10. Follow instructions for lubricating, chain
tensioning and changing the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
Cut wood only. Do not use pruning saw for
11.
purposes not intended. For example: do not
use pruning saw for cutting metal, plastic,
masonry or non-wood building materials. Use
of the pruning saw for operations different than
intended could result in a hazardous situation.
12. This pruning saw is not intended for tree fell-
ing. Use of the pruning saw for operations differ-
ent than intended could result in serious injury to
the operator or bystanders.
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 pruning saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
Kickback is the result of pruning saw 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 fin-
gers encircling the pruning 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 precau-
tions are taken. Do not let go of the pruning
saw.

• Do not overreach and do not cut above
shoulder height. This helps prevent unin-
tended tip contact and enables better control
of the pruning saw in unexpected situations.
• Only use replacement guide bars and saw
chains specified by the manufacturer.
Incorrect replacement guide bars and saw
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.
14. Follow all instructions when clearing jammed
material, storing or servicing the pruning saw.
Make sure the switch is off and the battery
pack is removed.
Additional Safety Instructions
Personal protective equipment
1. Clothing must be close-fitting, but must not
obstruct mobility.
Wear the following protective clothing during work:
2.
• 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).
Operation
1. Before starting work, check that the tool 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
correctly;
• The chain has been sharpened and ten-
sioned in accordance with the regulations.
2. Do not start the tool with the chain cover being
installed on it. Starting the tool with the chain
cover being installed on it may cause the chain
cover to thrown out forward resulting in personal
injury and damage to objects around the operator.
3. Do not stand directly under the branch that
is being cut. Pay attention to the falling
branches.
4. Do not operate the tool in bad weather or if
there is a risk of lightning.
5. When you use the tool on muddy ground, wet
slope, or slippery place, pay attention to your
footing.
Electrical and battery safety
1. Avoid dangerous environment. Don't use the
tool in damp or wet locations or expose it to
rain. Water entering the tool will increase the
risk of electric shock.
2. Do not dispose of the battery(ies) in a fire.
The cell may explode. Check with local codes for
possible special disposal instructions.
3. Do not open or mutilate the battery(ies).
Released electrolyte is corrosive and may cause
damage to the eyes or skin. It may be toxic if
swallowed.
