•
Only use replacement bars and chains specied 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.
KICKBACK SAFETY DEVICES ON THIS CHAIN SAW
Chain Brake
The chain saw comes equipped with a chain brake, which stops both the motor and the motion
of the chain when kickback occurs. The chain brake can be activated by the forward motion of
the chain kickback brake handle as the saw rotates backward during kickback.
WARNING
Never modify or attempt to disable the chain brake.
Make sure that the chain brake is working properly before using the chain saw. The chain
kickback brake handle should move back and forth easily.
To test the operation of the chain brake,
perform the following steps (Fig. 1):
•
Place the chain saw on a at bare surface
and make sure no objects or obstructions
that could come in contact with the bar and
chain are in the immediate vicinity.
•
Disengage the chain brake by pulling the
chain kickback brake handle towards the
front handle.
•
Start the chain saw.
•
Push the chain kickback brake handle
towards the front of the saw. A properly
functioning hand brake will stop the
movement of the chain immediately. If the
chain brake is not working properly, do not
use the chain saw until it has been repaired by a qualied service technician.
WARNING
Conrm that the chain brake works properly before each use.
WARNING
If the chain brake is clogged with wood chips, the function of the
chain brake may deteriorate. Always keep the device clean.
Low Kickback Saw Chain
The rakers (depth gauges) ahead of each cutter can minimize the force of a kickback
reaction by preventing the cutters from digging in too deeply at the kickback zone. Only use
a replacement chain that is equivalent to the original chain or has been certied as a low
kickback chain per ANSI B175.1. A low kickback tooth saw chain is a chain that has met
the kickback performance requirements of ANSI B175.1 (American National Standard for
Power Tools - Gasoline-Powered Chain Saws-Safety Requirements) when tested on the
representative sample of chain saws below 3.8 c.i.d. specied in ANSI B175.1.
CAUTION
As saw chains are sharpened during their useful life, they lose some of the
low kickback qualities and extra caution should be used.
Guide Bar
This saw comes equipped with a guide bar that has a small radius nose. Small radius noses
generally have less potential for kickback. When replacing the guide bar, please order the
guide bar we recommend in this manual or the guide bar with the correct specication with
regarding to this product.
