Motor Specifications and Electrical Requirements (continued)
Polarized Plug
Your unit has a plug that looks like the one
shown on next page.
To reduce the risk of electrical shock, this
appliance has a polarized plug (one blade
is wider than the other). This plug will fit in
a polarized outlet only one way, if the plug
does not fit fully in the outlet, reverse plug.
If it still does not fit, contact a qualified
electrician to install the proper outlet. Do
not change the plug in any way.

Motor Safety Protection

1. Connect this tool to a 120v, 15-amp
branch circuit with a 15-amp time delay
fuse or circuit breaker. Using the wrong
size fuse can damage the motor.
2. If the motor won't start, release the trig-
ger switch immediately. Unplug The
Tool. Check the saw blade to make
sure it turns freely. If the blade is free,
try to start the motor again. If the motor
still does not start, refer to the "Motor
Troubleshooting Chart."
3. If the motor suddenly stalls while cut-
ting wood, release the trigger switch,
unplug the tool, and free the blade from
the wood. The motor may now be
restarted and the cut finished.
4. Fuses may "blow" or circuit breakers
may trip frequently if:

Wire Sizes

NOTE: Make sure the proper extension
cord is used and is in good condition. The
use of any extension cord will cause
some loss of power. To keep this to a min-
imum and to prevent overheating and
motor burn-out, use the table below to
determine the minimum wire size (A.W.G.)
extension cord.
For circuits that are farther than 100 feet
away from electrical service box, the wire

safety precautions when operat-
ing this tool.

can occur if you cut too rapidly or
make too many start/stops in a short
time.
b. Line voltages are more than 10%
above or below the nameplate volt-
age. For heavy loads, however, the
voltage at motor terminals must equal
the voltage specified on nameplate.
c. Improper or dull saw blades are used.
5. Most motor troubles may be traced to
loose or incorrect connections, over-
load, low voltage (such as small size
wire in the supply circuit) or to overly
long supply circuit wire. Always check
the connections, the load and the sup-
ply circuit whenever motor doesn't work
well. Check wire sizes and length with
the Wire Size Chart below.
size must be increased proportionately in
order to deliver ample voltage to the saw
motor.
