KEY CHAIN SAW TERMS
Ballistic A special material used in protection devices designed to
reduce the risk of penetration from chain contact.
Binding Closing of the cut or shifting of the wood, possibly
trapping the saw blade in the cut. Binding includes
pinching. (Also, see PINCH.)
Chain Catcher A projection designed to reduce the risk of the operator’s
right hand from being hit by a chain, which has broken or
derailed from the guide bar during cutting.
Chain Tensioner The device which permits precise adjustment of the chain
tension.
Chaps Specially designed leg protection, which can reduce the
risk of injury due to contact with a moving saw chain.
Follow Through After the chain saw completes a cut and is no longer
supported by the wood, an uncontrolled chain saw can
continue on its path and strike the legs, feet or body of
the operator.
Front Hand
Guard
This required device is intended to reduce the operator’s
risk of injury from projecting branches and saw-chain
contact with the left hand in the event the operator loses
his grip from the upper part of the handle.
Guide Bar The grooved bar that supports and guides the saw chain.
Kerf The grooved cut produced by the saw chain cutters.
Kickback The general term describing rotational and linear
kickback, two highly dangerous reactions which can
occur when operating a chain saw. When used alone
in this manual, the term “kickback” refers to rotational
kickback. To prevent kickback, keep the bar nose
properly covered with the optional Kick Guard
TM
device.
If the optional Kick Guard device is absent, kickback can
occur if the unshielded bar nose touches an object or the
ground.
Rotational
Kickback
The violent reaction which can occur when the chain at
the upper section of the nose is suddenly stopped or
impeded, thereby dangerously driving the bar nose in an
upward arc toward the operator.
Linear Kickback A push reaction, which can occur under certain
conditions with the guide bar buried in the cut when the
cut closes, pinching the chain along the top rails of the
guide bar and propelling the chain saw straight back
toward the operator.
Kick Guard
Device
Optional Anti-kickback device attached to the bar nose.
