WM-90 PLASTER/MORTAR Mixer General Information

WM-90 PLASTER/MORTAR MIXER — GENERAL INFORMATION

Application

The MQ Whiteman WM-90 series mixers (drum capacity of

9.0cu. ft./254.8 liters) are shipped completely assembled and have been factory tested and are ready for use.

This mixer is only intended for the production 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 2-1/2 and 3-1/2 bags.

Power Plants

The WM-90 can be powered by a Honda GX240K1HA2 air- cooled, 4-stroke gasoline engine or a 3 HP 115/230V 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.

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 capacity as ref- erenced in Table 5. Remember cable distance affects the current-voltage capacity 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. Use Table 3 as general guideline when torqueing of mixer hardware is required. Remember to keep all mixer hardware components tight.
