CONNECTING DISC SANDER 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 disc sander is wired for 110-120 volt, 60 HZ alternating current. Before connecting the disc sander to the power source, make sure the switch is in the “OFF” position. The motor provides a no-load speed of 1725 RPM.

GROUNDING INSTRUCTIONS

CAUTION: 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. 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 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 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 under- stood, or if in doubt as to whether the tool is properly grounded.

grounding type plugs and 3-hole receptacles that accept the tool's plug, as shown in Fig. 5.

Repair or replace damaged or worn cord immediately.

This tool is intended for use on a normal 120-volt circuit and has a grounded plug that looks like the plug illus- trated in Fig. 5.

If a properly grounded outlet is not available, a temporary adapter, shown in Fig. 6, 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 prop- erly grounded outlet can be installed by a qualified elec- trician. The green colored rigid ear, lug, or the like extending from the adapter must be connected to a per- manent 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.

CAUTION: IN ALL CASES, MAKE CERTAIN THE RE- CEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE HAVE A CERTIFIED ELEC- TRICIAN CHECK THE RECEPTACLE.

Use only 3-wire extension cords that have 3-prong
