WC-62P/S CONCRETE MIXER — ELECTRIC MOTOR

Electric Motor

For maintenance care and operation of the electric motor, refer to your electric motor instruction booklet furnished with the electric motor.

Protect the electric motor from dust as much as possible and keep ventilating openings clean.

CAUTION:

DO NOT spray water at any time on the electric motor.

DO NOT operate electric motor in a explosive environment.

The electric motor used in this mixer is a single-phase 1.5 HP motor. The input voltage requirement for this motor is either 115 or 230 VAC only.

Electric Motor Connection

A 12 inch electrical cable (Figure 2) with a pigtail at one end is provided with the electrical motor for hookup to a power source. Table 1. shows the required NEMA connector for the desired motor horsepower rating. In addition, Table 2 also shows the matching NEMA approved connector for the required extension cord.

ALWAYS, make certain that the power source required for the electric motor is correct and always use the correct NEMA configuration plug. Failure to supply the correct voltage to the motor can severely damage the motor.

The electric motor supplied with the mixer is configured from the factoryfor115VACgroundedoperation.Makecertainthatthecorrect size grounded (3-wires) extension cord is used.See Table 5.

Motors can burn out when the line voltage falls 10% below the voltage rating of the motor. Failure to use proper voltage will cause the motor to overheat and actuate the overload switch.

If overload protection should actuate because of improper voltage or any other malfunction, turn the main switch on the motor to the "OFF" position and correct the problem, press the reset switch button, and turn the main switch to the "ON" position.

Electric Motor Voltage Change Switch

1.ALWAYS make certain the electric motor's ON/OFF switch is in the "OFF" position and the power cord has been disconnected from the power source.

2.Remove the voltage change lock-out bolt and nut (Figure 6). Change the position of the voltage change toggle switch from 115 VAC to 230 VAC.The mixer is factory wired for 115 VAC operation.

3.Re-install the voltage change lock-out bolt and nut.
