MOTOR SAFETY PROTECTION
IMPORTANT
To avoid motor damage, the motor
should be blown out or vacuumed
frequently to keep sawdust from
interfering with the motor ventilation.
1. Connect this saw to a 120 V circuit.
This circuit must not be less than a
#14 wire with a 15 A time lag fuse.
NOTE: When using an extension
cord on a circuit with a #14 wire, the
extension cord must not exceed 25
feet in length.
2. If the motor will not start, release
the trigger switch immediately.
UNPLUG THE SAW. Check the saw
blade to make sure it turns freely. If
the blade is free, try to start the saw
again. If the motor still does not start,
refer to the TROUBLESHOOTING
GUIDE.
3. If the t0ol suddenly stalls while
cutting wood, release the trigger
switch, unplug the tool and free
the blade from the wood. The saw
maynow be started and the cut
finished.

4. FUSES may "blow" or circuit
breakers may trip frequently if:
a. MOTOR is overloaded -
overloading can occur if you feed
too rapidly or make too many
start/stops in a short time.
b. LINE VOLTAGE is more
than 10% above or below the
nameplate voltage rating. For
heaw loads, the voltage at motor
_ terminals must equal the voltage
specified on the nameplate.
C. IMPROPER or dull saw blades
are used.
5. Most motor troubles may be traced
to loose or incorrect connections,
overload, !oWvoltage or inadequate
power supplywiring. Always check
the connections, the load and
supply circuit if the motor doesn't
run well. Check minimum gauge for
the length of cord you are using on
the chart below.
GUIDELINES FOR EXTENSION
CORDS
Use a proper extension cord. Make
sure your extension cord isin good
condition. When using an extension
cord, be sure to use one heavy enough
to carry the current your product will
draw. An undersized cord will cause
a drop in line voltage, resulting in
loss of power and overheating. The
table below shows the correct size
to use depending on cord length and
nameplate ampere rating. If in doubt,
use the next heavier gauge. The
smaller the gauge number, the heavier
the cord.
Be sure your extension cord is
properly wired and in good condition.
Always replace a damaged extension
cord or have it repaired by a qualified
person before using it. Protect your
extension cords from sharp objects,
excessive heat and damp or wet areas.
Use a separate electrical circuit
for your tools. This circuit must not
be less than a #14 wire with a 15 A
time lag fuse. NOTE: When using
an extension cord on a circuit with
a #14 wire, the extension cord must
not exceed 25 feet in length. Before
connecting the tool to the power line,
make sure the switch is in the OFF
position and the electric current is
rated the same as the current stamped
on the motor nameplate, running at a
lower voltage will damage the motor.
