MC-92P/S CONCRETE MIXER — GENERAL INFORMATION

Application

This mixer is only intended for the production of concrete. The mixer must be used for its intended purpose and is not suitable for the mixing of flammable or explosive substances. The mixer must not be used in an explosive atmosphere. Use Table 4 (Mixing Hints) as a guide when mixing concrete for various applications.

Power Plants

The Multiquip MC-92P and MC-92S mixers can be powered by a variety of power plants or an electric motor. Refer to Table 2 to for specific engine or electric motor data information. All engines are air-cooled, 4-stroke gasoline engines.

Electrical

Ensure that the extension cable is carefully laid out avoid- ing wet areas, sharp edges and locations where vehicles might run over it. Avoid allowing the extension cable to be trapped underneath the mixer.

Unroll the extension cable fully or it will overheat and could catch fire. Make sure that all extension cable connections are dry and safe. Replace any defective or badly worn ex- tension cable immediately.

Hardware

Check all hardware on the mixer before starting. Periodically inspect all hardware. Loose hardware can contribute to early component failure and poor performance. UseTable 3 as general guideline when the torqueing of mixer hardware is required. Remember to keep all mixer hardware components tight.

If mixer is equipped with an electric motor, make sure that the power being supplied to the motor corresponds to the voltage rating label on the motor.Supplying the wrong voltage to the electric motor will cause severe electrical damage to the motor.

Always make sure the OFF/ON switch on the electric motor is in the OFF position before applying power.

It is strongly recommended when inserting the mixer's power cord into a receptacle, that a G.F.C.I. (Ground Fault Current Interrupter) receptacle be used (115 VAC applications).

The extension cable should be a 3-wire configuration that includes a ground wire that conforms to UL code. The wire cross section must be a minimum of 2.5 mm2 . Choose an extension cord of adequate current carrying as Referenced in Table 6. Remember distance affects the wire size of the extension cable.

Engine Maintenance

For basic engine maintenance, refer to the engine maintenance section in this manual. For a more detailed engine maintenance, refer to the Honda or Robin Engine Owner's manual furnished with the engine.

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.
