Guidelines For Extension Cords - Craftsman 137.407530 Operator's Manual

3. If the tool suddenly stalls while
cutting wood, release the trigger
switch, unplug the tool, and free the
blade from the wood. The saw may
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 cause 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 #12 wire with a 20 Atime-lag
fuse or 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.

i CAUTION i
in all cases make certain the
receptacle in question is properly
grounded. If you are not sure, have
a certified electrician check the
receptacle.
