MC-92P/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.SeeTable 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 MotorVoltage 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 115VAC to 230VAC.The mixer is factory wired for 115 VAC operation.

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

MC-92P, MC-92S specifications

The Multiquip MC-92S and MC-92P are high-performance concrete mixers designed for professional use in construction and masonry applications. These models offer a blend of power, durability, and user-friendly features, catering to the demands of contractors and construction workers who require reliable equipment for mixing concrete, mortar, and other materials.

The MC-92S is equipped with a robust 9.0 horsepower Honda gasoline engine that provides ample power for even the most demanding mixing tasks. This model features a 9 cubic feet capacity drum, allowing for larger batches of mixed material. The MC-92S is designed with a heavy-duty steel frame that enhances its durability and stability during operation. The drum is constructed with abrasion-resistant steel, ensuring longevity and minimizing wear over time.

In contrast, the MC-92P utilizes a powerful 9.0-horsepower propane engine, making it an excellent choice for users who prefer cleaner fuel options. This model retains many of the same design features as the MC-92S, including the enhanced drum capacity and rugged frame. The propane engine not only provides a quieter operation but also reduces emissions, making it a more environmentally friendly option without compromising performance.

One of the standout technologies in both models is the innovative mixing mechanism. The unique design of the mixing blades ensures efficient and consistent blending of materials, reducing the time required for mixing and enhancing the quality of the final product. Additionally, the MC-92 series features a manual dump system, which allows operators to easily and accurately discharge mixed material from the drum.

Safety is a primary concern in construction, and Multiquip has incorporated several safety features into these mixers. The control panel is designed for easy access and includes safety switches that prevent accidental start-up. The sturdy base and low center of gravity provide stability during operation, reducing the risk of tipping.

In summary, the Multiquip MC-92S and MC-92P concrete mixers are exceptional tools for professionals needing reliable, efficient, and versatile mixing equipment. With their powerful engines, capacity, durability, and innovative mixing technologies, they stand out in the competitive market of concrete mixers, ensuring that construction projects run smoothly and efficiently.
