CONNECTING TOOL TO POWER SOURCE

POWER CONNECTIONS

A separate grounded electrical circuit should be used for your tool. This circuit should not be less than #12 wire and should be protected with a 20 amp fuse or circuit breaker. Before connecting the tool to the power line, make sure the switch is in the “OFF” position.

If the power cord is worn, cut or damaged in any way, have it replaced immediately by a certified electrician to avoid electrical shock or fire hazard.

MOTOR SPECIFICATIONS

Your tool is designed to use a 1720 RPM motor. It is wired at the factory for 120 Volts, 60 Hz alternating current. Never use a motor that runs faster than 1720 RPM.

GROUNDING INSTRUCTIONS

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.

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. The motor 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-hole receptacles that accept the tool’s plug.

Repair or replace damaged or worn cord immediately.

IMPORTANT: IN ALL CASES , MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

120 VOLT OPERATION

As received, your drill press is ready-to-run for 120 volt operation. This drill press, when wired for 120 volts, is intended for use on a circuit that has an outlet and a plug that looks like the one shown in Fig. 13.

If a properly grounded outlet is not available, a temporary adapter, shown in Fig. 14, 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.
