Electrical

Power Supply and Motor Specifications

The AC motor used in this saw is a universal, nonreversible type (see Motor in the Specifica- tions sect ion on page 8).

To avoid electrical hazards, fire hazards, or damage to the machine, use proper circuit protection. Your saw is wired at the f actory for 120V operation. Conne ct t o a 120V, 15 Amp circuit and use a 15 amp time delay fuse or circuit br eaker. If pow er cord is worn or cut , or damaged in any w ay, have it replaced immediat ely to avoi d shock or f ire.

Elect ri cal Requirements

This machine is double insulated to provide a double thickness of insulatio n between the user and t he machine's electrical system. All e xposed metal part s are isolated f rom the internal metal motor components with protective insulation.

This saw has a plug that looks like the one shown in Figure A.

Extension Cords

Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current yo ur machi ne will draw . An under sized cord will cause a drop in the line voltage resulting in power loss and overheating. The table below shows the correct size to use depending on the cord length and nameplate ampere rati ng. If in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier the cord.

Cord Length AWG 00 – 25ft 016 25 – 50ft 014

Important: Make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle.

Figure A

To reduce the risk of electrical shock, this saw has a polarized plug (one blade is wider t han t he other). This pl ug will fit i n a polari zed outlet o nly one way; if the plug does not fit fully in the outlet, rever se the pl ug. I f it st ill does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in a ny way.

Double insulation does not take the place of normal safety precautions when operating this tool.

To avoid electrocution:

1. Use only identical replacement parts when

servicing a tool with double insulation. Servicing should be perf or med by a q ualified technician.

2. Do not use power tools in wet or damp

locations or expose t hem to rain or snow.
