CONNECTING DRILL PRESS 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 charac- teristics as indicated on the tool. All line connections should make good contact. Running on low voltage will dam- age the motor.

MOTOR SPECIFICATIONS

Your drill press is designed to use a 1720 RPM motor. It is wired at the factory for 110-120 Volts, 60 Hz alternating cur- rent. Never use a motor that runs faster than 1720 RPM. Your drill press may be converted for 220-240 volt operation. The conversion of your drill press for 220-240 volt operation must be done by qualified electrical personnel.

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 ground- ing plug. The plug must be plugged into a matching out- let 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 out- let, have the proper outlet installed by a qualified electri- cian.

Improper connection of the equipment-grounding con- ductor 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 con- ductor. 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 under- stood, 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-hole 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 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 illustrat- ed in Fig. A.

If a properly grounded outlet is not available, a temporary adapter, shown in Fig. B, may be used for connecting the 3-prong grounding type plug to a 2-prong 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.

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

250volts, inclusive:

This tool is intended for use on a circuit that has an out- let that looks like the one illustrated in Fig. C. The tool has a grounding plug that looks like the plug illustrated in Fig. C. 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 reconnected for use on a different type of elec- tric circuit, the reconnection should be made by quali- fied service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

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

FIED ELECTRICIAN CHECK THE RECEPTACLE.
