Motor Specifications and Electrical Requirements

Motor Safety Protection
IMPORTANT: To reduce the risk of motor
damage, the motor should be blown out
or vacuumed frequently to keep sawdust
from interfering with normal motor ventila-
tion.
1. Connect this tool to a power source
with the appropriate voltage for your
model and a 15-amp branch circuit with
a 15-amp fuse or circuit breaker. Using
the wrong size fuse can damage the
motor.
2. If the motor won't start, turn off the
power switch immediately and unplug
the tool. Check the spindle to make
sure it turns freely. If the spindle is free,
try to start the motor again. If the motor
still does not start, refer to the "Trouble-
shooting” chart.
3. If the motor suddenly stalls while sand-
ing, turn off the power switch, unplug
the tool, and remove the workpiece
from the belt/drum. The motor may now
be restarted and the sanding finished.
4. Fuses may "blow" or circuit breakers
may trip frequently if:
a. Motor Is Overloaded-Overloading
can occur if you sand too rapidly or
make too many start/stops in a short
time.
b. Line voltages should not be more
than 10% above or below the name-
plate voltage. For heavy loads, how-
ever, the voltage at motor terminals
must equal the voltage specified for
your model.
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 supply
circuit whenever motor doesn't work
well. Check wire sizes and extension
cord length with the Wire Size Chart.
Wire Sizes
NOTE: Make sure the proper extension
cord is used and is in good condition.
The use of any extension cord will cause
loss of power. To keep this to a minimum
and to prevent overheating and motor
burn-out, use the table shown to deter-
mine the minimum wire size (A.W.G.)
extension cord.
Use only 3-wire extension cords with 3-
prong grounding type plugs and 3-pole
receptacles.
