Kickback Safety Precautions – Chainsaw
DANGER
•
Kickback may occur when the nose or tip of the guide bar touches an object, or
when the wood closes in and pinches the chainsaw in the cut. Tip contact in
some cases may cause a lightning fast 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 can result in
serious personal injury.
•
Do not rely exclusively on the safety devices built into the saw. As a chainsaw
user, you should take several steps towards keeping cutting jobs free from
injury or accidents.
•
With basic understanding of kickback, you can reduce or eliminate the element of
surprise. Sudden surprises contribute to accidents.
•
Keep a good grip on the saw with both hands, with your right hand on the rear
handle and your left hand on the front handle when the engine is running. Use a
firm grip with thumbs and fingers encircling the chainsaw handles. A firm grip will
help you reduce kickback and maintain control of the saw.
•
Make certain that the area in which you are cutting is free from obstructions. Do
not let the nose of the guide bar contact a log, branch or any other obstruction
which could be hit while you are operating the saw.
•
Cut while the engine is at high speed.
•
Make sure the chain and guide bar are correctly adjusted before operating the
equipment. Never attempt chain adjustments with the engine running!
•
Always make sure the cutting attachment is properly installed and firmly
tightened before operation.
•
Never use a cracked or warped guide bar; replace it with a new one and make
sure it fits correctly.
•
If a saw blade should bind fast in a cut, shut off the engine immediately. Push the
branch or tree to ease the bind and free the blade.
•
Do not operate the pole pruner with the muffler removed.
•
When cutting a limb that is under tension, be alert for spring-back so that you will
not be struck by the moving limb.
•
Always stop the engine immediately and check for damage if you strike a foreign
object or if the machine becomes tangled. Do not operate with broken or
damaged equipment.
•
Do not make unauthorised modifications or substitutions to the guide bar or
chain.
•
Never allow the engine to run at high speeds with a load. Doing so could damage
the engine.
•
Keep the pruner as clean as possible. Keep it free from loose vegetation, mud, etc..
