GENERAL INFORMATION

Application

The MQ WM120 series hydraulic mixers (drum capacity

12.0cu. ft./340 liters) are shipped completely assembled and have been factory tested and are ready for use.

This mixer is only intended for the mixing of plaster and mortar. 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.This mixer has a batch capacity between 3-1/ 2 and 4-1/2 bags.

Power Plants

These hydraulic mixers can be powered by either a 11 HP Honda GX390 air-cooled, 4-stroke gasoline engine or a 5.0 HP electric motor. Refer to Table 2 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.

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 capacity as referenced in Table 5. Remember cable distance affects the current-voltage capacity of the extension cable.

Ensure that the extension cable is carefully laid out avoiding 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 extension 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. Use Table 4 as general guideline when torqueing of mixer hardware is required. Remember to keep all mixer hardware components tight.

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 Engine Owner's manual furnished with the engine.
