8. Carry the chain saw by the front handle with the
chain saw switched off and away from your
body. When transporting or storing the chain
saw always fit the guide bar cover. Proper
handling of the chain saw will reduce the likelihood
of accidental contact with the moving saw chain.
9. Follow instructions
tensioning 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
purposes 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.
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
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 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
maintenance instructions for the saw chain.
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;
• The bar and the sprocket cover are fitted
correctly;
• 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
personal injury and damage to objects around the
operator.
Additional Safety Warnings:
1. When using the tool with battery adapter, be
careful not to trip over the cord during operation.
2. When using the tool with battery adapter, keep
the cord away from obstacles such as a
workpiece and branches during operation. The
cord caught by obstacles may cause serious injury.
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,
recommendations 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
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.
5. Do not fill the chain oil near fire. Never smoke
when you fill the chain oil.
6. National regulation may restrict the use of the
chain saw.
7. 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
authorized service center for the inspection and
repair.
8. Always activate the chain brake before starting
the chain saw.
9. Hold the saw firmly in place to avoid skating
(skid movement) or bouncing of the saw when
starting a cut.
