Oregon ® 91P meets the reduced-kickback requirements of ANSI B175.1 when
tested on a representative sample of chainsaws. This chain significantly reduces
the risk of chainsaw kickback while maintaining high cutting performance. ALL
CUTTING CHAIN CAN KICK BACK, WHICH MAY RESULT IN SEVERE INJURY TO
THE SAW OPERATOR OR BYSTANDERS. Users should be cautioned to operate their
saw safely, and to read and follow all warnings in their saw operator’s manual and
Oregon
® 91P chain-maintenance instructions.
Failure to follow filing instructions can
increase the level of kickback which
can result in severe injury to the saw operator or bystanders.
* Do not exceed the depth-gauge setting shown above
* Always file depth gauges back to their original rounded
or ramped shape after lowering

WARNING
Because every
cut counts
Standard 3/8”-pitch chains are full-size professional-type chains intended for
use on medium to large gasoline-powered saws, 3.0 to 6.0 cu. in. (50-100cc).
Low-profile 3/8” chains have the same pitch, but there are differences in the
drive sprockets and bar-nose sprockets used with low-profile chains. Standard
3/8” chains and low-profile 3/8” chains are NOT interchangeable. The phrase
“low profile” refers to the height, measured from the bar’s rail to the top of the
cutter. On low-profile chains, the height is less than on standard chains. Low-
profile 3/8”-pitch chains are intended for use on electric saws, and small gasoline-powered saws up to 2.5 cubic inches (41cc).
