device for stopping or locking the saw-chain, activated manually or non-manually when kickback occurs
brake which is actuated irrespective of operator intervention when a kickback occurs
device, usually the front hand-guard used to activate the chain brake
a structural barrier between the front handle of the chain-saw and the saw-chain for protecting the hand from injury if the hand slips off the handle, and may also be the device used to activate the chain brake
a shield that prevents contact with the saw-chain at the tip of the guide bar, which may be removable and replaceable, for reducing the incidence of rotational kickback
a structural barrier at the bottom right side of the rear handle of the chain-saw for protecting the hand from the saw-chain if the saw-chain breaks or degrooves
device fitted in front of the mounting point of the guide bar acting as a pivot when it is in contact with a tree or log
suspension point located behind or within the rear handle,which allows for the attachment of a safety strap, carabiner or rope, as appropriate
engine speed at which the saw-chain does not move
Note 1 to entry: A range of idling speeds is normally identified by the chain-saw manufacturer and stated in the instruction handbook.
engine speed at which maximum corrected brake power is obtained
Note 1 to entry: The maximum power speed is obtained in accordance with ISO 7293[1]
maximum engine speed achieved at full open throttle or the engine speed at 133 % of the maximum power speed , whichever is the lesser
The angle calculated by a mathematical simulation that describes the peak bar nose position when a handheld chain saw is subjected under simulated conditions to a rotational kickback impulse.
Note 1 to entry: see figure 6.
A computer derived value that computes the resultant CKA with chain brake engaged at the point when the motion of the saw chain has stopped.BS ISO 6531 pdf free download.
