FEATURES AND BENEFITS
CHAIN
58- AND 59-SERIES SQUARE-GROUND CHAINS
These new Oregon® .404”-pitch Super Guard® chains have been carefully developed to replace the
popular 52AJ/AK/AL family of square-ground chains. Users of our previous 52-series chains will find it
easy to make the switch. 58CJ/CL, and 59CJ/CK/CL all feature a fast-working new chisel cutter that
delivers performance superior to its predecessors in all cutting modes. The new cutter is mounted on
our proven unequal-pitch 59 chassis for superior performance and durability. These chains give
professional timber cutters who use square-ground .404”-pitch chains what they want: out-of-box
sharpness, the ultimate in performance, resistance to stretch, and consistency from chain to chain.
These chains feature ramped depth gauges to reduce kickback energies, and are recommended for
cutting clean wood with saws 4.0 cubic inches (65cc) and larger, and with bars 20" (50cm) and longer.
Safety/ANSI: 58CJ/CL and 59CJ/CK/CL are yellow-label chains with kickback-reducing
features. These chains do not meet the kickback requirements for low-kickback chains.
Recommended Use: Professional use by loggers and forest firefighters who prefer
large saws and square-ground .404”-pitch chain.

WHO SHOULD USE SQUARE-GROUND CUTTING CHAINS?
more difficult to sharpen and less forgiving of filing
errors than the round-ground chains used by most
woodcutters. But for professional users cutting larger
wood, square-ground chains are often preferred.
Square-ground chains are intended for professional
users who cut larger wood with guide bars 30” and
longer. The advantage of square-ground chain is its
fast-cutting performance. The disadvantage is that it is
FILING INSTRUCTIONS FOR 58CJ/CL AND 59CJ/CK/CL CHAINS
CORRECT FILE POSITION
FILE IS TOO HIGH
FILE IS TOO LOW
IMPORTANT NOTE: Several shapes of files can be
used to sharpen square-ground chain. But whichever
shape you prefer, the key to sharpening square-
ground chain is file positioning. The file will sharpen
the top plate and side plate simultaneously. This
creates a line (A). You must position your file so this
line intersects the cutter’s “Working Corner” (B), or
your square-ground chain will not perform properly.
Line A intersects corner B

Oregon .404”-pitch Super Guard square-ground chains
(58CJ/CL and 59CJ/CK/CL) may be capable of kickback
Failure to follow filing instructions can
increase the level of kickback which
that could result in serious injury to the saw operator or bystanders.
Although these chains have features designed to reduce kickback energy, they
are NOT low-kickback chains. Do not use Oregon 58CJ/CL or 59CJ/CK/CL unless
you have experience and specialized training for dealing with kickback. Saw chain
with lower kickback potential is available.
