Powermatic 511 operating instructions Operation, Extension Cords

The green wire must be the only wire connected to the machine’s grounding system and must never be attached to an electrically “live” terminal.

A temporary adapter, shown in Figure 6, can be used to connect a grounded plug to a two-prong outlet. The green rigid ear or lug extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box or receptacle. Simply remove the center screw from the outlet, insert the adapter and re-attach the screw through the grounding ear to the outlet. If in doubt of proper grounding, call a qualified electrician. A temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. The Canadian Electrical Code prohibits use of temporary adapters.

Extension Cords

Grounded tools require a three-wire extension cord. As the distance from the supply outlet increases, a heavier gauge extension cord must be used. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.

Figure 7 shows recommended gauges. The smaller the gauge number of the wire, the greater capacity of the cord (for example, a 12- gauge cord can carry a higher current than a 14- gauge cord). If one extension cord is used for more than one tool, add their nameplate amperes and use the sum to determine the required minimum wire size.

If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.

Be sure your extension cord is properly wired and in good condition. Always replace a damaged cord or have it repaired by a qualified person before using it. Protect extension cords from sharp objects, excessive heat, and damp or wet areas.

Operation

Crosscut rulers: The panel saw comes with one rip (vertical) ruler and two crosscut (horizontal) rulers. The rip ruler is preset at the factory. The crosscut rulers should be checked and, if necessary, adjusted before operating the saw. Also, they should be adjusted after every blade change. See “Adjusting Crosscut Rulers” on page 15.
