WARNING 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.  
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  
gasoline engine Care  
geneRaL  
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.  
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.  
On/OFF Switch (gasoline Model Only)  
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.  
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)  
Before Starting  
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.  
Before starting if using a gasoline model mixer, read the

drum Head Seals  
NOTICE  
There is 1 set of drum head seals (Figure 23) that will  
require lubrication.  
Lubricating grease Fittings  
Failure to lubricate the drum bearing grease fittings  
periodically will cause the dumping mechanism  
to stiffen, making the mixing drum hard to dump.  
NOTICE  
Important- drum Head Seal Care  
Countershaft Bearing Lubrication  
Grease seals every 40 hours of operation  
using any grade #1 lithium base grease. Apply  
grease until visible of mixing tub (over grease).  
This will purge seal system of contamination.  
There is 1 set of countershaft bearings (Figure 25) that will  
require lubrication. Lubricate the grease fitting for each  
countershaft bearing every 40 hours of operation using  
any grade lithium base grease.

drum Bearing Bracket Lubrication  
Figure 25. Grease Fittings (Countershaft)  
grease Fittings (Zerk) Maintenance (electric Motor)  
There is 1 set of drum bearing brackets (Figure 24) that  
will require lubrication. These brackets are intended to  
make the drum rotate freely. Lubricate the grease fitting for  
each drum bearing bracket every month or when the  
drum becomes difficult to position using multi-purpose  
grade grease.  
1. 1.There are two grease (Figure 18) fittings at each  
end of the electric motor that will require lubrication.  
Lubricate these fittings about every 16 months.  
2. Use Poleyrex EM (Exxon Mobil) or equalivant lubricant.  
Clean grease fitting, apply grease gun to fitting (1/2  
shot). Remember too much grease or injecting grease  
too quickly can cause premature bearing failure.Slowly  
apply the recommended amount of grease, taking a  
miniute or so to apply.

3. Disconnect the spark plug wire. In addition make sure  
the clutch engagement lever is dis-engaged to relieve  
V-belt tension.  
The surface of the pinion and main gear (Figure 29) should  
be very lightly greased.  
NOTICE  
4. The countershaft and drive pinion are mounted on a  
slotted base.To align drive pinion with main gear, loosen  
the pillow block mounting bolts and move them until  
the necessary alignment has been made. Remember  
gears must be paralleled aligned not skewed.  
Re Grease main and pinion gears every 250 hours of  
operation. IMPORTANT! avoid over-greasing. Excess  
grease will accumulate contaminates and cause  
premature wear.  
5. Using your hand, slightly move (rock) the drive pulley  
back and forth to determine the amount of backlash.  
Insert feeler gauge between gears to determine  
backlash distance. Backlash should range between  
0.007- 0.012 inches (Figure 27).
