MC-42S 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 MQWhiteman mixer can be powered by either a Honda GX120K1QX2 air-cooled, 4-stroke gasoline engine or a 1/2 HP electric motor. Refer to Table 1 to for specific engine or electric motor data information.

Electrical

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).

Extension Cables

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.

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.
