EC-42S 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 1/2 HP motor. The input voltage requirement for this motor is 115 VAC.

Electric Motor Connection

A 12-inch power cable (Figure 6) with a 3-prong grounding type male plug is provided with the electrical motor for hookup to a power source.

ALWAYS, make certain that the power source required for the electric motor is correct . Failure to supply the correct voltage to the motor can severely damage the motor. Always read the nameplate on the electric motor to determin the proper input voltage.

The electric motor supplied with the mixer is configured from the factory for 115 VAC grounded operation. ALWAYS, make certain that the correct size, grounded extension cord (3-wires) is used. See Table 5.

Motors can burn out when the line voltage falls 10% below the voltage rating of the motor. Length of the extension cord can greatly affect the operating voltage of the motor.Reference Table 5 for recommended extension cord size with recpect to distance. Failure to operate electric motor at correct voltage will cause 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.

Table 5. Recommended Extension Cord Sizes

Electric	Input	50 ft.	75 ft.	100 ft.	200 ft.
Motor	Voltage	(15.24 m)	(22.86 m)	(30.48 m)	(60.96 m)
1/2 HP	115 VAC	No. 12	No. 10	No. 8	No. 6

CAUTION:

ALWAYS make certain the electric motor's ON/ OFF switch is working properly.When the mixer is not in use, place the ON/OFF switch in the "OFF" position and disconnect the power cord from the power source.

	NEVER! disable or disconnect the
NOTE	ON/OFF switch on the electric motor.
	It is provided for operator safety.Injury
	may result if it is disable, disconnected
	or improperly maintained.
