KICK-BACK
Kick-back may occur when the nose of the guide bar
touches an object or when the wood closes in and
pinches the saw chain in the cut. The nose of guide
bar contact in some cases may cause a lightning-fast
reverse reaction kicking the guide bar up and back
toward the operator. Pinching the saw chain along the
top of the guide bar may push the guide bar rapidly
back toward 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
chainsaw user, you should take several steps to keep
your cutting jobs free from accident or injury.
1. With a basic understanding of kick-back, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
2. Keep a good rm grip on the saw with both hands
when the engine is running. Place your right hand on
the rear handle and your left hand on the front handle
with your thumbs and ngers encircling the chainsaw
handles. A rm grip together with a stiff left arm will
help you maintain control of the saw if kick-back
occurs.
3. Make sure 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, fence, or any other obstruction
that could be hit while you are operating the saw.
4. Cut at high engine speeds. Always cut with the engine
running at full speed. Fully squeeze the throttle trigger
and maintain a steady cutting speed.
5. Do not overreach or cut above chest height.
6. Follow the manufacturer's
maintenance instructions for the saw chain.
7. Use only replacement bars and chains speci ed by the
manufacturer or the equivalent.
NOTE: Refer to "Operation" in this manual for information
on kick-back and how to avoid serious personal injury.
WHITE FINGER RISKS
Prolonged use of chainsaws expose operators to harmful
vibration that may lead to white nger risks. Symptoms
include episodic blanching of ngers in response to cold,
numbness and tingling. In extreme cases, it will cause loss
of touch sensation.
Anti-vibration system does not guarantee that you will
not suffer white nger risks. Operators should observe
their hands and ngers. If the above symptoms occur,
operators should seek medical advice immediately.
