Kickback Path
KICKBACK is the backward, upward or sudden forward motion of the guide bar occurring
when the saw chain near the upper tip of the guide bar contacts any object such as a log or
branch, or when the wood closes in and pinches chain in the cut. Contacting a foreign object
in the wood can also result in loss of chain saw control.
When kickback occurs the chainsaw reacts unpredictably and can cause severe injuries
to the operator or bystanders. Particular attention must be given when sawing sideways,
slanted or during length cuts, as the spiked bumper usually cannot be applied.
To avoid kickback:
• Saw with guide bar at a flat angle.
• Never work with a loose, widely stretched or the heavily worn out chain.
• Ensure chain is sharpened correctly.
• Never saw above shoulder height.
• Never work with the tip of the guide bar.
• Always hold the chain saw firmly with both hands.
• Always use a low kickback chain.
• Whenever possible, apply the spiked bumper against the log for leverage.
• Ensure correct chain tension.

Use the chain saw only with secure footing.
Hold the chain saw at the right-hand side of your body. (See Figs. 11 and 12)
The chain must be running at full
speed before it makes contact
with the wood.
Whenever possible, apply the
spiked bumper teeth (9) against the
log as a leverage point while cutting.
Use the bumper teeth to secure the
saw onto the wood before starting
to cut.
The teeth allow user to pivot the
saw and maintain position while
sawing. (See Fig. 13)
