Powermatic Comprehensive Guide to the Reset Button and Safety Features in Tools

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 circuit that has an outlet that looks like the one illustrated in A, Figure

13.An adapter, shown in B and C, may be used to connect this plug to a 2-pole receptacle as shown in B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. This adapter is not permitted in Canada. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.

3.Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating between 150 - 250 volts, inclusive:

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in D, Figure

13.The tool has a grounding plug that looks like the plug illustrated in D. 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 electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

8.2Voltage conversion

To switch the incoming power leads for 230 volt operation, follow wiring diagram on inside cover of motor junction box (A, Figure 14). A similar diagram is found in section 16.0 of this manual. (In case of discrepancy, diagram in junction box takes precedence.)

The plug on the end of the motor cord must be replaced with a UL/CSA listed plug rated for 230V.

8.3Overload reset button

If saw becomes overloaded and the motor shuts off, open motor cover and push reset button (B, Figure 14) to restart. If overloading happens frequently, consult the Troubleshooting section in this manual.

8.4Extension cords

USE PROPER EXTENSION CORD. 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 your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

8.5Magnetic switch and safety key

Refer to Figure 15.

The start switch has a power indicator lamp which is on whenever there is power connected to the saw, not just when the saw is running. Do not assume that no light means there is no power to the machine. If the bulb is bad, there will be no indication. Always check before use.
