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 3-pole receptacles which 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

Your tool is wired for 120 volt, 60 HZ alternating current. Before connecting the tool to the power source, make sure

the switch is in the “OFF” position. The motor provides a no-load speed of 1720 RPM.

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:

This tool is intended for use on a normal 120-volt circuit

and has a grounded plug that looks like the plug

illustrated in Fig. 18.

If a properly grounded outlet is not available, a temporary

adapter, shown in Fig. 19, may be used for connecting the

3-prong grounding type plug to a 2-pole receptacle. 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, or the like extending from

the adapter must be connected to a permanent ground

such as a properly grounded outlet box cover. 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

conductor can result in risk of electric shock. The

conductor with insulation having an outer surface that is

green with or without yellow stripes is the equipment-

grounding conductor. If repair or replacement of the

electric cord or plug is necessary, 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

grounding type plugs and 3-pole receptacles that accept

the tool’s plug, as shown in Fig. 18.

Repair or replace damaged or worn cord immediately.
