EM-90 PLASTER/MORTAR MIXER — GENERAL INFORMATION
Application
The MQ Essick EM-90 series mixers (drum capacity of 9.0
cu. 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 . Themixermustbeusedforitsintendedpurpose
andisnot suitable for themixingof 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-90 can be powered by a Honda GX240K1HA2 air-
cooled,4-strokegasolineengineor a 3 HP 115/230V electric
motor. Refer to Table 2 for specific engine or electric motor
datainformation.
Electrical
If mixer is equipped with an electric motor , make sure that
the power being supplied to the motor corresponds to the
voltageratinglabelon themotor.Supplyingthewrong 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
trappedunderneaththe 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
Checkall hardwareon the mixer before starting.Periodically
inspectallhardware.Loosehardwarecancontributetoearly
component failure and poor performance. Use Table 4 as
general guideline when torqueing of mixer hardware is
required.Rememberto keepallmixerhardwarecomponents
tight.
