SPEED AND WIRING
The no-load speed of this product is approximately 3,450
rpm. This speed is not constant and decreases under a
load or with lower voltage. For voltage, the wiring in a
shop is as important as the motor’s horsepower rating. A
line intended only for lights cannot properly carry a power
tool motor. Wire that is heavy enough for a short distance
will be too light for a greater distance. A line that can
support one power tool may not be able to support two
or three products.
GROUNDING INSTRUCTIONS
This product must be grounded. In the event of a malfunction
or breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock.
This product is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
WARNING:
Improper installation of the grounding plug is able to
result in a risk of electric shock. When repair or
replacement of the cord is required, do not connect the
grounding wire to either flat blade terminal. The wire with
insulation having an outer surface that is green with or
without yellow stripes is the grounding wire.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the product is properly grounded.
Repair or replace a damaged or worn cord immediately.
This product is for use on a nominal 10 volt circuit and
has a grounding plug similar to the plug illustrated in figure
1. Only connect the product to an outlet having the same
configuration as the plug. Do not use an adapter with this
product.

EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding
plugs and 3-pole receptacles that accept the product’s plug.
When using a power tool at a considerable distance from
the power source, use an extension cord heavy enough to
carry the current that the product will draw. An undersized
extension cord will cause a drop in line voltage, resulting in
a loss of power and causing the motor to overheat. Use the
chart provided below to determine the minimum wire size
required in an extension cord. Only round jacketed cords
listed by Underwriter’s Laboratories (UL) should be used.

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
When working with the product outdoors, use an extension
cord that is designed for outside use. This is indicated by the
letters “WA” on the cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with
a power tool. Failure to do so can result in serious per-
sonal injury.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use the product with a dam-
aged cord since touching the damaged area could cause
electrical shock resulting in serious injury.
ELECTRICAL CONNECTION
This product is powered by a precision-built electric motor.
It should be connected to a
power supply that is 120 volts,
60 Hz, AC only (normal household current). Do not oper-
ate this product on direct current (DC). A substantial voltage
drop will cause a loss of power and the motor will overheat.
If the product does not operate when plugged into an outlet,
double check the power supply.
