EM-70 PLASTER/MORTAR MIXER — OPERATION MANUAL — REV. #1  (008/10/04) — PAGE 15

EM-70 PLASTER/MORTAR MIXER — GENERAL INFORMATION

Application

The MQ Essick EM-70 series mixers (drum capacity of 7.0
cu. ft./198 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 EM-70 can be powered by either a Honda GX240K1HA2
or GX160K1HX2 air-cooled, 4-stroke gasoline engine or a
1.5 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 mm

2

. 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 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.
