WARNING: WE DO NOT REPRESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN
BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. DO NOT RELY UPON ANY
OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND
CAREFULLY TO AVOID KICKBACK.
Reduced-Kickback Guide Bar and Low-Kickback Chain
Reduced-kickback guide bars and low-kickback saw chains reduce the chance and magnitude of kickback
and are recommended. Your saw has a low kickback chain and bar as original equipment. Repairs on a
chain brake should be made by an authorized servicing dealer. Take your unit to the place of
purchase if purchased from a servicing dealer, or to the nearest authorized service dealer.
WARNING: Computed kickback angle (CKA) listed on your saw and listed in the CKA
table below represents angle of kickback your bar and chain combinations will have
when tested in accordance with ANSI standard. When purchasing replacement bar and
chain, considerations should be given to the lower CKA values. Lower CKA values
represent safer angles to the user, higher values indicate more angle and higher kick
energies. Computed angles represented indicate total energy and angle associated
without activation of the chain brake during kickback. Activated angle represents chain
stopping time relative to activation angle of chain break and resulting kick angle of saw.
In all cases lower CKA values represent a safer operating environment for the user. The
following guide bar and chain combinations meet kickback requirements of ANSI B175.1
when used on saws listed in this manual. Use of bar and chain combinations other than
those listed is not recommended and may not meet the CKA requirements per
standard.
WARNING: Do not mount a bow guide on any Efco chainsaw. The risk of kickback is
increased with a bow guide because of the increased kickback contact area.
