SAFETY RULES

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 CSA (Canadian Standards Association) and ANSI standards. 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.
