S Pinch-Kickback can occur when the the
wood closes in and pinches the moving
saw chain in the cut along the top of the
guide bar and the saw chain is suddenly
stopped. This sudden stopping of the
chain results in a reversal of the chain
force used to cut wood and causes the
sawtomoveintheoppositedirectionofthe
chain rotation. The saw is driven straight
back toward the operator.
S Pull-In can occur when the moving chain
contacts a f oreign object in the wood in the
cut alongthe bottom ofthe guidebar and the
saw chain is suddenly stopped. This sudden
stopping pulls the saw forward and away
from theoperator and couldeasily causethe
operator to lose control of the saw .

which contributes to accidents.

ject at the tip of the guide bar.
S Keep the working area free from obstruc-
tionssuchas othertrees,branches,rocks,
fences, stumps, etc. Eliminate or avoid
any obstruction thatyour saw chain could
hit while you are cutting. When cutting a
branch, do not let the guide b ar contact
branch or other objects around it.

tensioned. A loose or dull chain can in-
crease the chance of kickback occurring.

sion at regular intervals with the engine
stopped, never with the engine running.
Make sure the bar nuts are securely tight-
ened after tensioning the chain.
