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 MQ Whiteman 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 mm
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. Use Table 3 as general
guideline when the torqueing of mixer hardware is required.
Remember to keep all mixer hardware components tight.
