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 your body and arm
positioned 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.
Additional warnings
It has been reported that vibrations from hand-held tools may contribute to a
condition called Raynaud’s Syndrome in certain individuals. Symptoms may
include tingling, numbness and blanching of the figures ,ususlly apparent upon
exposure to cold and dampness, diet, smoking and work practices are all thought
to contribute to the development of these symptoms. It is presently unknown
what, if any, vibrations or extent of exposure may contribute to the condition.
There are measures that can be taken by the operator to possibly reduce the
effects of vibration:
•
Keep your body warm in cold weather, when operating the unit wear gloves
to keep the hands and wrists warm. It is reported that cold weather is a
major factor contributing to Raynaud’s Syndrome.
•
After each period of operation, exercise to increase blood circulation.
•
Take frequent work breaks. limit the amount of exposure per day.
If you experience any of the symptoms of this condition, immediately discontinue
use and see your physician about these symptoms.
•
The recommended cutting capacity of this chain saw is 153mm (6 in.) and
smaller to prolong the life of the tool and allow for safest operation.
•
Cutting logs with a diameter larger than this will cause excess wear on
your tool. Logs with a maximum diameter of 229mm (9in.) can be cut, but
should only be done so rarely and with caution.
•
The integral spiked bumper is designed to assist cutting. When forced
against the log while cutting it provides a more stable pivot point.
•
Any chain saw is potentially lethal if used inappropriately. It is strongly
suggested that you seek professional training in the safety and use of this
tool.
