MC-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.
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.
CAUTION:
■
DO NOT spray water at any time on the
electric motor
.
■
DO NOT operate electric motor in a
explosive environment.
NOTE
NEVER!
disable or disconnect the
ON/OFF switch on the electric motor.
It is provided for operator safety. Injury
may result if it is disable, disconnected
or improperly maintained.
