RIDGID MS1290LZ manual Motor Safety Protection, Wire Sizes, Polarized Plug

Motor Specifications and Electrical Requirements (continued)

Polarized Plug

Your unit has a plug that looks like the one shown on next page.

To reduce the risk of electrical shock, this appliance has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way, if the plug does not fit fully in the outlet, reverse plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

WARNING: Double insulation does not take the place of normal safety precautions when operat- ing this tool.

Motor Safety Protection

1.Connect this tool to a 120v, 15-amp branch circuit with a 15-amp time delay fuse or circuit breaker. Using the wrong size fuse can damage the motor.

2.If the motor won't start, release the trig- ger switch immediately. Unplug The Tool. Check the saw blade to make sure it turns freely. If the blade is free, try to start the motor again. If the motor still does not start, refer to the "Motor Troubleshooting Chart."

3.If the motor suddenly stalls while cut- ting wood, release the trigger switch, unplug the tool, and free the blade from the wood. The motor may now be restarted and the cut finished.

4.Fuses may "blow" or circuit breakers may trip frequently if:

a. Motor Is Overloaded-Overloading can occur if you cut too rapidly or make too many start/stops in a short time.

b. Line voltages are more than 10% above or below the nameplate volt- age. For heavy loads, however, the voltage at motor terminals must equal the voltage specified on nameplate.

c. Improper or dull saw blades are used.

5.Most motor troubles may be traced to loose or incorrect connections, over- load, low voltage (such as small size wire in the supply circuit) or to overly long supply circuit wire. Always check the connections, the load and the sup- ply circuit whenever motor doesn't work well. Check wire sizes and length with the Wire Size Chart below.

Wire Sizes

NOTE: Make sure the proper extension cord is used and is in good condition. The use of any extension cord will cause some loss of power. To keep this to a min- imum and to prevent overheating and motor burn-out, use the table below to determine the minimum wire size (A.W.G.) extension cord.

For circuits that are farther than 100 feet away from electrical service box, the wire

size must be increased proportionately in order to deliver ample voltage to the saw motor.

Extension Cord	Wire Sizes
Length	Required for 120V
	(A.W.G.)
0-25 Ft.	14
26-50 Ft.	12
