■
■
■
Check wheel mounting lug nuts with a torque wrench.  
Torque wheel lug nuts as described in the maintenance  
section of this manual.  
Towing Safety Precautions  
CAUTION:  
Check tightness of U-clamp nuts, torque suspension  
hardware as referenced in the maintenance section of this  
manual.  
■
Check with your county or state safety  
towing regulations department before  
towing your mixer.  
Avoid sudden stops and starts.This can cause skidding, or  
jackknifing. Smooth, gradual starts and stops will improve  
gas milage.  
To reduce the possibility of an accident while transporting  
the mixer on public roads, always make sure that the mixer  
towing components and the towing vehicle are in good  
operating condition and both units are mechanically sound.  
Avoid sharp turns to prevent rolling.  
CAUTION:  
The following list of suggestions should be used when towing  
the mixer:  
If the mixer tow bar is deformed or damaged  
replace entire tow bar. NEVER tow the mixer  
with a defective tow bar. There exist the  
possibility of the trailer separating from the  
towing vehicle.  
■
Make sure that the hitch and coupling of the towing vehicle  
are rated equal to, or greater than the trailer "gross vehicle  
weight rating" (GVWR).  
■
■
■
■
■
■
ALWAYS inspect the hitch and coupling for wear. NEVER  
tow the mixer with defective hitches, couplings, chains etc.  
Tow Bar to Vehicle Connection (Coupler Only)  
1. Check the vehicle hitch ball, and mixer's coupler for  
signs of wear or damage. Replace any parts that are  
worn or damaged before towing.  
CHECK the tire air pressure on both the towing vehicle and  
the trailer.Also check the tire tread wear on both vehicles.  
ALWAYS make sure the mixer is equipped with a "Safety  
Chain".  
2. Use only a 2-inch ball diameter (towing vehicle), this  
will match the mixer's 2-inch coupler. Use of any other  
ball diameter will create an extremely dangerous condition  
which can result in separation of the coupler and ball or  
ball failure.  
ALWAYS attach trailer's safety chain to the frame of towing  
vehicle.  
ALWAYS make sure that the towing vehicle's directional,  
backup, and brake lights are working properly.  
3. After tow bar has been connected to mixer (see next  
page), attach mixer's coupler to the hitch ball on the  
towing vehicle securely and make sure the lock lever  
is in the down position (locked).  
Remember in most cases the maximum speed unless  
otherwise posted for highway towing is 45 MPH, however  
before towing your mixer, check your local state, and county  
vehicle towing requirements. Recommended off-road towing  
is not to exceed 10 MPH or less depending on type of terrain.  
■
■
■
■
Place chocked blocks underneath wheels to prevent rolling,  
while parked, if disconnected from towing vehicle.  
Mixer Tow Bar Vehicle Connection (Pintle and Loop)  
1. Make sure the bumper on the towing vehicle is  
equipped to handle either a pintle or loop type tow  
bar configuration.  
Inflate tires to correct pressure, inspect tires for cuts, and  
excessive wear.See Table 16 (Tire Wear Troubleshooting).  
When towing of the mixer is required, place the drum in the  
up position (mouth facing upwards).  
2. After tow bar has been connected to mixer (see next  
page), secure either type of tow bar to the towing vehicle,  
following state and county towing regulations.  
ALWAYS make sure that the fuel valve lever is in the OFF  
position (gasoline models only).  
3. As a minimum, use a 1/2-inch bolt and nylock nut grade  
5 when securing either tow bar to the towing vehicle,

MC-44S CONCRETE MIXER — SAFETY CHAIN CONNECTION  
2. Route the safety chain through the holes just above the  
tow bar, located on each side of the mixer stand.  
CAUTION:  
NEVER ! tow the mixer with the safety chain  
removed. The safety chain is intended to  
prevent complete separation of the mixer from  
the towing vehicle in the event of a tow bar  
failure.  
Loop the chain together and place under the tow bar.  
Secure the loop with the connector link.  
3. Extend the safety chain along the length of the tow bar,  
looping it through the tow bar's connector link. Remove  
any excess chain slack.  
Reference Figure 5 for the installation of the Safety Chain.  
4. Connect the free end of (clevis safety hook) the safety  
chain to the towing vehicle. Remember it is critical  
that the length of the chain be properly adjusted, to  
prevent the draw bar and the front of the mixer stand  
from dropping to the the ground (contact) in the event  
the draw bar becomes disconnected from the towing  
vehicle.  
Tow Bar to Mixer Connection  
1. Insert the tow bar through the round opening at the  
bottom of the mixer stand.  
Align the hole on the tow bar with the hole on the mixer  
frame, and insert 1/2-inch bolt through tow bar and frame.  
Secure tow bar to frame with 1/2-inch nylock nut.Tighten  
to 40 ft.-lbs.

ALWAYS make certain the electric motor's ON/OFF switch  
is in the "OFF" position and the power cord has been  
disconnected from the power source.  
The electric motor used in this mixer is a single-phase 1.5 HP  
motor. The input voltage requirement for this motor is either 115  
or 230VAC only.  
Electric Motor Connection  
NEVER! disable or disconnect the  
ON/OFF switch on the electric motor.  
A 12 inch electrical cable (Figure 2) with a pigtail at one end is  
provided with the electrical motor for hookup to a power source.  
Table 1. shows the required NEMA connector for the desired  
motor horsepower rating. In addition, Table 2 also shows the  
matching NEMA approved connector for the required extension  
cord.  
It is provided for operator safety.Injury  
may result if it is disable, disconnected  
or improperly maintained.  
ALWAYS, make certain that the power source required for the  
electric motor is correct and always use the correct NEMA  
configuration plug. Failure to supply the correct voltage to the  
motor can severely damage the motor.  
The electric motor supplied with the mixer is configured from the  
factoryfor115VACgroundedoperation.Makecertainthatthecorrect  
size grounded (3-wires) extension cord is used.SeeTable 5.  
Motors can burn out when the line voltage falls 10% below the  
voltage rating of the motor. Failure to use proper voltage will  
cause the motor to overheat and actuate the overload switch.  
If overload protection should actuate because of improper voltage  
or any other malfunction, turn the main switch on the motor to the  
"OFF" position and correct the problem, press the reset switch  
button, and turn the main switch to the "ON" position.

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.  
Ball Socket and Clamp Face Maintenance  
1.  
If the towing vechicle is equipped with a ball socket, smear  
socket periodically with multi-purpose grease. This will keep  
the ball socket well lubricated.  
2.  
3.  
Periodically oil pivot points and clamp face surfaces of  
coupler with SAE 30 WT. motor oil.  
Wheel Bearings  
1. After every 3 months of operation, remove the hub dust cap  
When parking or storing your mixer. Keep the coupler off  
the ground so dirt will not build up in the ball socket.  
and inspect the wheel bearings (Figure 28).Once a year,  
or when required, disassemble the wheel hubs remove  
the old grease and repack the bearings forcing grease  
between rollers, cone and cage with a good grade of high  
speed wheel bearing grease (never use grease heavier  
than 265 A.S.T.M. penetration (“No. 2.”)  
Grease Fittings (Zerk) Maintenance (Mixer)  
There are 3 grease (Figure 26) fittings that will require  
lubrication. Lubricate these fittings once a week. Use lithium  
base grease, grade N0.1.  
Figure 28. Wheel Hub and Bearings  
Figure 26. Grease Fittings Mixer  
2.  
Fill the wheel hub (Figure 28) with grease to the inside  
diameter of the outer races and also fill the hub grease cap.  
Reassemble the hub and mount the wheel. Then tighten  
the adjusting nut, at the same time turn the wheel in both  
directions, until there is a slight bind to be sure all the  
bearing surfaces are in contact.  
Grease Fittings (Zerk) Maintenance (Electric Motor)  
1.  
There are two grease (Figure 27) fittings at each end of the  
electric motor that will require lubrication. Lubricate these  
fittings about every 16 months.  
Then back-off the adjusting nut 1/6 to 1/4 turn or to the  
nearest locking hole or sufficiently to allow the wheel to  
rotate freely within limits of .001" to .010" end play.Lock the  
nut at this position. Install the cotter pin and dust cap, and  
tighten all hardware.  
Mixer Cleaning  
1.  
For thorough mix and longer drum life, always wash drum  
out after each use.  
2.  
NEVER! pour or spray water over the engine or electric  
motor.

MC-44S CONCRETE MIXER — MAINTENANCE (MIXER)  
Tires/Wheels/Lug Nuts  
Tires and wheels are a very important and critical compo-  
nents of the trailer. When specifying or replacing the trailer  
wheels it is important the wheels, tires, and axle are prop-  
erly matched.  
CAUTION:  
DO NOT attempt to repair or modify a  
wheel. DO NOT install an inter-tube to  
correct a leak  
through the rim.  
If the rim is cracked, the air  
pressure in the inter-tube may  
cause pieces of the rim to explode  
(break-off) with great force and  
can cause serious eye or bodily  
injury.  
Suspension  
The rigid suspension and associated components (Figure  
29) should be visually inspected every 6,000 miles for signs  
of excessive wear, elongation of bolt holes, and loosening  
of mounting bracket. Replace any damaged suspension  
component immediately.  
TiresWear/Inflation  
Tire inflation pressure is the most important factor in tire  
life. Pressure should be checked cold before operation. DO  
NOT bleed air from tires when they are hot. Check inflation  
pressure weekly during use to insure the maximum tire life  
and tread wear.  
Table 8 (Tire Wear Troubleshooting) will help pinpoint the  
causes and solutions of tire wear problems.  
CAUTION:  
ALWAYS wear safety glasses when  
removing or installing force fitted  
parts. Failure to comply may result  
in serious injury.

MC-44S CONCRETE MIXER — MAINTENANCE (MIXER)  
Lug NutTorque Requirements  
It is extremely important to apply and maintain proper wheel  
mounting torque on the trailer. Be sure to use only the fas-  
teners matched to the cone angle of the wheel. Proper pro-  
cedure for attachment of the wheels is as follows:  
1. Start all wheel lug nuts by hand.  
2. Torque all lug nuts in sequence. See Figure 30. DO NOT  
torquethewheellugnutsallthewaydown.Tighteneachlug  
nut in 3 separate passes as defined by Table 9.  
3. Afterfirstroaduse,retorquealllugnutsinsequence.Check  
all wheel lug nuts periodically.  
NEVER! use an pneumatic air gun  
to tighten wheel lug nuts.  
Mixer Storage  
For storage of the mixer for over 30 days, the following is  
recommended:  
Drain the fuel tank completely, or add STA-BIL to the  
fuel.  
Run the engine until the fuel is completely consumed.  
Completely drain used oil from the engine crankcase  
and fill with fresh clean oil, then follow the procedures  
described in the engine manual for engine storage.  
Clean the entire mixer and engine compartment.  
Place the mixing drum in the down position (mouth facing  
downward).  
Cover the mixer and place it a clean dry area, that is  
protected from harsh elements.
