WM-70 PLASTER/MORTAR MIXER — GENERAL INFORMATION
Application
The MQ Whiteman WM-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 WM-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
