SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

GENERAL INFORMATION
GENERAL
The MQ Model WM45H and WM45E plaster and mortar
mixers are shipped completely assembled and each mixer
has been factory tested.
The drum batch capacity of these mixers is between 1.5 and
2.5 bags. With proper care it will give continuous service
year after year.
These mixers can be powered by either a Honda GX160
gasoline engine or a 1 HP electric motor (115/230 VAC, 60
Hz). The shaft of the engine or electric motor is connected
to a drive belt pulley which is attached to a main gear. As
the main gear rotates it causes the paddle shaft to rotate.
Before Starting
Before starting if using a gasoline model mixer, read the
engine owner's manual and thoroughly understand the
safety information.
Check the items listed below:
Oil Levels (Gasoline Model Only)
Gasoline Engine Care
For care and operation of the Honda engine, refer to the
maintenance procedures in this manual and the engine
manufacturer’s operating instructions furnished with the
engine. We recommend draining and refilling the engine
crankcase at least every thirty hours of operation. Check
the engine oil level daily.
ON/OFF Switch (Gasoline Model Only)
This feature is on gasoline engine mixers only. Located on
the side of the engine cover. The purpose of this switch is
to start and stop the mixer in normal operation.
ON/OFF Switch (Electric Model Only)
This feature is on electric motor mixers only. This switch is
located on top of the motor. Lift the engine cover to gain
access to this switch. The purpose of this switch is to start
and stop the mixer in normal operation. NEVER use the
electric motor in an explosive environment.
Be sure to check the oil levels in the engine and engine
reduction unit before starting the unit (gasoline model only).
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 the
torque chart below as a general guideline and keep all
hardware tight:
HARDWARE DIA TORQUE (lb./ft.)

COMPONENTS
Figure 2. Major Components
Figure 2 illustrates the basic components and controls of
the WM45H and WM45E mixer.
1. Lifting Handle Bars — Use these handle bars to lift
and maneuver the mixer.
2. Pivot Point/Zerk Fitting — There is, on each end of
the mixing drum a zerk grease fitting. These fittings
lubricate the dumping mechanism. Lubricate both
fittings at least twice a week.
3. Safety Grill — Provided for operator safety. This safety
grill is designed to keep hands and solid objects out of
the mixing drum when in use. This grill should be closed
at all times when mixer is in use. DO NOT remove the
grill or grill opening bar. Keep the grill clean by washing
it down daily.
4. Mixing Paddles — Used in the mixing of material.
This unit uses four different types of paddles to provide
a fast uniform mix.
5. Bag Cutter — This feature allows compound mixing
bags to be opened easily, therefore allowing the
contents of the bag to fall directly into the mixing drum.
6. Engine Cover — Lift this cover to gain access to the
engine compartment.
7. Lifting Handle Bars (Engine Side) — Use these
fold-down handle bars to lift and maneuver the mixer.
8. Engine ON/OFF Switch — Pull switch outward to start
engine. Push inward to stop engine. This feature is on
gasoline models only.
9. Tires — Replace tires with the recommended type
tire of 12 x 3.
10. Chock Blocks — Place these blocks (not included
as part of the mixer package) under each mixer wheel
to prevent rolling.
11. Steel Mixing Drum — Mixing materials such as mortar,
plaster are to be placed into this drum for mixing.
Always clean the drum after each use
12. Dump Handle — Pull this handle downward to dump
the contents of the drum. Push the handle upward to
return the drum to its vertical position.

BASIC ENGINE
INITIAL SERVICING
The engine (Figure 3) must be checked for proper
lubrication and filled with fuel prior to operation. Refer to
the manufacturers engine manual for instructions and
details of operation and servicing. Fuel Filler Cap —
Remove this cap to add unleaded gasoline to the fuel tank.
Make sure cap is tightened securely. DO NOT over fill.
DANGER
Adding fuel to the tank should be done
only when the engine is stopped and has
had an opportunity to cool down. In the
event of a fuel spill, DO NOT attempt to
start the engine until the fuel residue has
been completely wiped up, and the area
surrounding the engine is dry.
1. Fuel Filler Cap — Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.
2. Throttle Lever — Used to adjust engine RPM speed
(lever advanced forward SLOW, lever back toward
operator FAST).
3. Engine ON/OFF Switch — ON position permits engine
starting, OFF position stops engine operations.
6. Choke Lever — Used in the starting of a cold engine,
or in cold weather conditions. The choke enriches the
fuel mixture.
7. Air Cleaner — Prevents dirt and other debris from
entering the fuel system. Remove wing-nut on top of
air filter canister to gain access to filter element.
NOTICE
Operating the engine without an air filter, with a
damaged air filter, or a filter in need of replacement
will allow dirt to enter the engine, causing rapid engine
wear.
WARNING
Engine co m p onent s can ge n e r a t e
extr em e he a t. To p r eve n t bu r ns,
DO NOT touch these areas while the
engine is running or immediately after
operating. NEVER operate the engine
with the muffler removed.
8. Spark Plug — Provides spark to the ignition system.
Set spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch).
Clean spark plug once a week.
9. Muffler — Used to reduce noise and emissions.
4. Recoil Starter (pull rope) — Manual-starting method.
Pull the starter grip until resistance is felt, then pull
briskly and smoothly.
5. Fuel Valve Lever — OPEN to let fuel flow, CLOSE to
stop the flow of fuel.
PAGE 14 — WM45H/E PLASTER/MORTAR MIXER • OPERATION AND PARTS MANUAL — REV. #0 (09/27/12)
10. Fuel Tank — Holds unleaded gasoline. For additional
information refer to engine owner's manual.
