Additional Safety Instructions - Makita DUC307 Instruction Manual

14. 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 chain 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
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 precau-
tions are taken. Do not let go of the chain
saw.

Do not overreach and do not cut above
•
shoulder height. This helps prevent unin-
tended tip contact and enables better control
of the chain 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.
15. Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is off and the battery
pack is removed. Unexpected actuation of the
chain saw while clearing jammed material or
servicing may result in serious personal injury.

Additional Safety Instructions

Operation
1. 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 ten-
sioned in accordance with the regulations.
2. 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.
3. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
4. When you use the tool on muddy ground, wet
slope, or slippery place, pay attention to your
footing.
5. Do not submerge the tool into a puddle.
6. Do not leave the tool unattended outdoors in
the rain.
Electrical and battery safety
1. Avoid dangerous environment. Don't use the
tool in dump 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.
4. Do not charge battery in rain, or in wet
locations.
5. Do not charge the battery outdoors.
Do not handle charger, including charger plug,
6.
and charger terminals with wet hands.
7. Do not replace the battery in the rain.
8. Do not replace the battery with wet hands.
Do not leave the battery in the rain, nor charge,
9.
use, or store the battery in a damp or wet
place.
10. Do not wet the terminal of battery with liquid
such as water, or submerge the battery. If the
terminal gets wet or liquid enters inside of battery,
the battery may be short circuited and there is a
risk of overheat, fire, or explosion.
11. After removing the battery from the machine or
charger, be sure to attach the battery cover to
the battery and store it in a dry place.
12. If the battery cartridge gets wet, drain the
water inside and then wipe it with a dry cloth.
Dry the battery cartridge completely in a dry
place before use.
