CHAIN SAW SAFETY
•
Make sure the saw chain is not in contact with anything before
starting the unit.
•
When carrying the unit, hold it away from the body, with the
guide bar positioned to the rear. Cover the guide bar and saw
chain with the scabbard when carrying the unit. Hold the unit by
the front handle.
•
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 2C 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. Take frequent
breaks and adjust your working position, as needed.
•
Do not operate the unit in a tree or on a ladder unless
specifically trained to do so.
•
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 unit is turned off. Do not use the unit if it
does not turn on and off properly. Have defective parts replaced
by an authorized service center.
•
Avoid starting the unit unintentionally. Make sure the trigger
lockout is in the locked position before installing or removing the
battery. Never carry the unit with fingers on the trigger.
•
Remove the battery from the unit when it is not in use.
•
Do not use the unit if the trigger and trigger lockout do not start
and stop the unit.
•
If the unit strikes or becomes entangled with a foreign object,
stop the motor immediately, remove the battery and allow the
unit to cool. Then, check for damage. If damaged, do not restart
or operate the unit until it is repaired. 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 your
authorized service center. 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. Stop the motor, remove the battery and
allow the unit to cool. Carefully remove vegetation and other
debris that could block moving parts.
•
If the unit starts to vibrate abnormally, stop the motor, remove the
battery and allow the unit to cool. Inspect the unit for the cause of
the vibration. Vibration is generally an indicator of trouble.
•
Always use the scabbard on the guide bar and saw chain during
transportation and storage.
•
Do not remove cut material, or hold material to be cut, when the
unit is running. Always turn the unit off, wait for the saw chain to
come to a complete stop, and remove the battery before
clearing jammed material. A moment of inattention can result in
serious personal injury.
KICKBACK SAFETY
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.
WARNING:
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.
