SHARPENING YOUR
HOMELITE
®
DUAL RAKER
SAW CHAIN
Kickback-suppressing type 35-MD50 semi-
chisel tooth, 9.5 mm (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 sup-
pressed 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.
Items Needed to Sharpen Chain

mark on file guide is parallel to center
of guide bar (see Figure 20). This will
insure that you file cutters at 30° angle.

ter until sharp. Only file in this one di-
rection (see Figure 20).

Two or
three strokes with file should sharpen
