CONNECTING TOOL TO POWER SOURCE
POWER CONNECTIONS
A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be
protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have
3-prong grounding type plugs and matching receptacle which will accept the tool’s plug. Before connecting the motor
to the power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same
characteristics as indicated on the tool. All line connections should make good contact. Running on low voltage will
damage the motor.
MOTOR SPECIFICATIONS
This tool is designed to be operated on 110-120 volt, 50/60 HZ alternating current and provides a no-load spindle
speed of 1720 RPM. Before connecting the tool to the power source, make sure the switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.

2. Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating less than 150
volts:
If the tool is intended for use on a circuit that has an outlet
that looks like the one illustrated in Fig. A, the tool will have
a grounding plug that looks like the plug illustrated in Fig. A.
A temporary adapter, which looks like the adapter illustrated
in Fig. B, may be used to connect this plug to a matching 2-
conductor receptacle as shown in Fig. B if a properly ground-
ed outlet is not available. The temporary adapter should be
used only until a properly grounded outlet can be installed by
a qualified electrician. The green-colored rigid ear, lug, and
the like, extending from the adapter must be connected to a
permanent ground such as a properly grounded outlet box.
Whenever the adapter is used, it must be held in place with
a metal screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
WARNING: IN ALL CASES, MAKE CERTAIN
THE RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A
CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected tools:
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 tool 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.
Improper connection of the equipment-grounding conduc-
tor can result in risk of electric shock. The conductor with
insulation having an outer surface that is green with or with-
out yellow stripes is the equipment-grounding conductor. If
repair or replacement of the electric cord or plug is neces-
sary, do not connect the equipment-grounding conductor
to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
Use only 3-wire extension cords that have 3-prong ground-
ing type plugs and matching 3-conductor receptacles that
accept the tool’s plug, as shown in Fig. 1.
Repair or replace damaged or worn cord immediately.
