Kickback-suppressing type 35-MD50 semi-
chisel tooth, 3/8" pitch, Dual Raker saw
chain has two rakers (depth gauges) instead
of just one gauge preceding each tooth.
When chain contact is made within the
kickback zone of a guide bar nose, the two
rakers provide sufficient support to prevent
the cutters from pulling themselves deeply
into the wood. Thus the tendency toward a
violent kickback reaction is suppressed or
reduced.
Keep chain sharp. Your saw will cut faster
and more safely. A dull chain will cause
undue sprocket, guide bar, chain and motor
wear. If you must force chain into wood and
cutting creates only sawdust with few large
chips, chain is dull.
