now 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
heavy 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, low voltage or inadequate
power supply wiring. 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 is in 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 #18 wire with a 9 A time lag
fuse. NOTE: When using an extension
cord on a circuit with a #18 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.

the receptacle in question is
properly grounded. If you are not
sure, have a certified electrician
check the receptacle.
