Kickback Safety - Champion 100647 Operator's Manual

100647 - ChAiNSAw
– Do not force the unit, especially near the end of a cut. It will do
a better, safer job when used at the intended rate.
– Always turn the engine off when operation is delayed, when
setting the unit down or when carrying the unit from one
location to another. Make sure all moving parts come to a
complete stop.
– Carry the unit by the front handle with the muffler positioned
away from the body and the guide bar positioned to the rear.
Cover the guide bar and saw chain with the scabbard when
carrying the unit.
– If you strike or become entangled with a foreign object, stop
the unit immediately and check for damage. Do not operate
the unit before repairing damage. Do not operate the unit with
loose or damaged parts.
– Use only original equipment manufacturer (OEM) replacement
parts and accessories for this unit. These are available from
Champion or other qualified service dealer. Use of any other
parts or accessories could lead to serious injury to the user,
or damage to the unit, and void the warranty.
– Keep the unit clean. Carefully remove vegetation and other
debris that could block moving parts.
– To reduce fire hazard, replace a faulty muffler and spark
arrestor. Keep the engine and muffler free from grass, leaves,
excessive grease or carbon build up.
– If the unit starts to vibrate abnormally, stop the unit
immediately. Inspect the unit for the cause of the vibration.
Vibration is generally an indicator of trouble.
– Keep the work area clean. Cluttered areas invite injuries.
Do not start cutting until the work area is clear and free from
obstructions. Make sure there is secure footing and a planned
retreat path from falling trees or branches.
– Do not cut near electrical cables or power lines. Keep at least
50 feet (15 m) away from all power lines.
– For safer, more effective performance, make sure the guide
bar and chain are properly cleaned, lubricated, tightened and
sharpened. Check the guide bar and chain at frequent intervals
for proper adjustment.
– When cutting a limb that is under tension, use extreme
caution. When the tension is released, the limb could spring
back and strike the operator, causing severe injury or death.
– Use extreme caution when cutting small-sized brush and
saplings, as slender material may catch the saw chain and be
whipped toward the operator or pull the operator off balance.
– This saw is classified by UL as a Class 1C saw in accordance
with CSA Z62.1-03. It is intended for infrequent use by
homeowners, cottagers and campers, and for general
applications such as clearing, pruning, cutting firewood, etc.
It is not intended for prolonged use. If the intended use
involves prolonged periods of operation, this may cause
circulatory problems in the user's hands due to vibration.
iMPORTANT SAfETY iNSTRUCTiONS
– Do not operate the unit in a tree or on a ladder unless
specifically trained to do so.
– Never remove, modify or make inoperative any safety device
furnished with the unit.
– Do not use the unit in the presence of flammable liquids or
gases.
– Do not attempt operations beyond the operator's capacity or
experience.
– Do not operate a unit that is damaged, improperly adjusted or
not completely and securely assembled. Make sure moving
parts stop when the throttle control trigger is released or the
unit is turned off. Do not use the unit if it does not turn on and
off properly. Have defective parts replaced by Champion or
other qualified service dealer.

Kickback Safety


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. In some cases, tip contact may cause
a lightening-fast reverse action, kicking the guide bar rapidly
back to wards 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
a loss of control over the saw, which could result in serious
injury to the user. Contact with foreign objects within the wood
can also induce a loss of chain saw control.
Understanding Kickback
A basic understanding of kickback can help reduce or eliminate
the element of surprise and the chance of kickback-related injury.
Sudden surprise contributes to accidents.
– Rotational Kickback can happen when the upper tip of
the guide bar contacts an object while the chain is moving
(Fig. A). This can cause the chain to dig into the object and
momentarily stop moving. The guide bar is then kicked up and
back toward the operator in a lightning-fast reverse reaction.
– Linear Kickback can happen when the wood on either side
of a cut closes in and pinches the moving saw chain along
the top of the guide bar (Fig. B). This can cause the chain
to instantly stop. The chain force is then reversed, causing
the saw to move in the opposite direction, sending the saw
straight back toward the operator.
– Pull-In can happen when the moving chain on the bottom
of the guide bar hits a foreign object inside the wood. This
can cause the chain to suddenly stop. The saw is then pulled
forward and away from the operator, which could potentially
result in the loss of control of the saw.
