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.

WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your tool is wired for 230 volt, 60 HZ alternating current. 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.

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 matching 3-conductor receptacles that accept the tool’s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

2.Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating between 150 -

250volts, inclusive:

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. Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool. If the tool must be re-connected for use on a different type of electric circuit, the re-connection should be made by qualified service personnel; and after re-connection, the tool should comply with all local codes and ordinances.

SINGLE PHASE INSTALLATION 31-390

The motor on your tool is wired for 230 Volt, single phase operation. The power cord is equipped with a plug that has two flat current carrying prongs in tandem and one round or "U" shaped longer ground prong. This is used only with the proper mating 3-conductor grounding type receptacle, as shown in Fig. A.

When the 230 Volt, three prong plug is plugged into a grounded 3-conductor receptacle, as shown in Fig. A, the long ground prong on the plug contacts first, so the tool is properly grounded before electricity reaches it.

THREE PHASE INSTALLATION 31-391

The motor on your tool is to be wired for 230 Volt, three phase operation, a power cord and plug is not supplied with the tool. To bring power to the tool proceed as follows:

1.Remove cover from the starter box.

2.Bring the three phase power cord through the en- trance hole in the bottom of starter box and connect the three power leads to terminals Ll, L2 and L3 and the ground wire to one of the terminals on the grounding strip shown in Fig. B.

3.Turn the tool on and off and check if the sanding belt is rotating in the right direction. The sanding belt should turn counterclockwise when looking down on the belt.

4.If the sanding belt is rotating in the wrong direction,

DISCONNECT THE TOOL FROM THE POWER SOURCE and interchange any two of the three leads that are connected to terminals Ll, L2, L3, Fig. B.

5.Replace cover on the starter box.

PERMANENTLY CONNECTED TOOLS:

If the tool is intended to be permanently connected the tool should be connected to a grounded metal permanent wiring system; or to a system having an equipment-grounding conductor.

WARNING: IN ALL CASES, MAKE CERTAIN THE MACHINE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE HAVE A

QUALIFIED ELECTRICIAN CHECK THE MACHINE.
