Safety Precautions
PRACTICE SAFE MAINTENANCE
Understand service procedure before doing work. Keep area clean
and dry.
Never lubricate, service or adjust machine while it is moving. Keep
hands, feet, and clothing from power-driven parts. Disengage all
power and operate controls to relieve pressure. Lower equipment to
the ground. Stop the engine. Remove the key. Allow machine to
cool.
Securely support any machine elements that must be raised for
service work.
Keep all parts in good condition and properly installed. Repair
damage immediately. Replace worn or broken parts. Remove any
buildup of grease, oil, or debris.
Disconnect battery ground cable (-) before making adjustments on
electrical systems or welding on machine.
DISPOSE OF WASTE PROPERLY
Improperly disposing of waste can threaten the environment and
ecology. Potentially harmful waste used with equipment include
such items as oil, fuel, coolant, brake fluid, filters, and batteries.
Use leakproof containers when draining fluids. Do not use food or
beverage containers that may mislead someone into drinking from
them.
Do not pour waste onto the ground, down a drain, or into any water
source.
Air conditioning refrigerants escaping into the air can damage the
Earths atmosphere. Government regulations may require a certified
air conditioning service center to recover and recycle used air
conditioning refrigerants.

SAFETY CHAIN INSTALLATION
Remove the safety chain kit from the engine
compartment. The kit includes (1) 12 ft. length of
safety chain and (2) connecting links. Pull one end of
the chain through the (2) key hole slots located in the
front post of the mixer with a hook (see drawing below
and decal on mixer front post). Attach the connecting
links to each end of the chain. Follow the instructions
in the TOWING section of this manual and on the
mixer front post to attach the safety chain to the towing
vehicle.
INSTALLING CHAIN TO MIXER
WARNING
BEFORE WORKING ON MACHINE, MAKE
SURE ENGINE SPARK PLUG WIRE IS
DISCONNECTED, OR IF ELECTRIC, THAT THE
ELECTRIC CORD IS DISCONNECTED, TO
PREVENT ANY ACCIDENTAL STARTING.
HARDWARE
Check all hardware on mixer and engine / motor before
starting. Consult the TORQUE CHART section of this
manual and tighten any loose hardware accordingly.
FUEL
If your mixer is equipped with a gasoline engine, fill
the gas tank with clean gasoline from a safety can.
Consult the ENGINE MANUAL supplied with this unit
for the proper type of gasoline required.
DO NOT mix oil with gasoline.
OIL LEVELS AND LUBRICATION
Be sure to check the oil levels in the engine and engine
reduction unit BEFORE starting this unit. The engine
warranty is VOID if it is run without oil. Consult the
ENGINE MANUAL supplied with this unit for specific
instructions and oil recommendations.
Also check the trunnion bearings to make sure they
have been greased.
WARNING
FOLLOW THE GUIDELINES FOUND IN THE
SAFETY PRECAUTION SECTION OF THIS
MANUAL WHENEVER HANDLING GASOLINE.
TO START THE ENGINE/MOTOR
GASOLINE ENGINE COLD START - Open the fuel
valve under the gas tank all the way. Open the throttle
approximately half way and apply the choke. Pull the
starter rope sharply until the engine starts. When the
engine starts, open the choke and adjust the throttle as
necessary to keep it running. Allow the engine to warm
up for a few minutes before placing it under the load.
If the engine doesn't start after (3) pulls, open choke
slightly to prevent flooding. Always operate the engine
at full throttle when under load.
- 14 -
Page 11
Gas Hot Start/Electric Motors/To
Operation
GASOLINE ENGINE HOT START - Open the valve
under the gas tank all the way if it has been shut off.
Open the throttle approximately half way. Do not
apply the choke. Pull the starter rope sharply until the
engine starts. When the engine starts, adjust the
throttle. Always operate the engine at full throttle
when under load. Adjust engine speed so drum is
turning between 20 - 25 RPM.
NOTE: These starting instructions are general
guidelines only. Since many engine options are
available on the manufacturer's CM mixers, consult the
ENGINE MANUAL included with this unit for specific
instructions.
ELECTRIC MOTORS - Use the proper size (3) wire
(grounded) extension cord, conforming to the National
Electric Code and Local Ordinances. DO NOT use (2)
wire extension cord. Check any extension cord
carefully for broken connectors, bare wires, and
damaged insulation. DO NOT use any cord found to be
in poor condition. Make sure the extension cord is not
routed through standing water and that all the
connections are tight. Use the shortest extension cord
possible. Turn motor on.
TO STOP THE ENGINE / MOTOR
Start and S top/Operation
OPERATION
Start the engine / motor as previously instructed and
allow gasoline engines to reach operating temperatures.
Close the engine cowl. NEVER operate the mixer with
cowl open.
With drum operating between 20 - 25 RPM's the mixer
is now ready for the addition of the concrete mix. For
best results proceed as follows:
1. Pour the required amount of water into
drum.
2. Add the required amount of gravel.
3. Add the required amount of cement.
4. Add the required amount of sand. By
adding the water and gravel first the
drum will be kept clean and a good
tumbling action will be maintained when
cement and sand will be added.
To discharge concrete, grasp handwheel firmly with
one hand and release tilt brake by pushing up on the tilt
handle with the other. See diagram below.
GASOLINE ENGINES - Depress grounding switch
located on stationary cowl half and hold down until
engine stops completely. Consult the ENGINE
MANUAL included with this unit for specific
instructions. If the mixer is to be left unattended for
any length of time, close the fuel valve under the gas
tank.
ELECTRIC MOTORS - Turn the motor off. If the
mixer is to be left unattended for any length of time,
disconnect the power cord.
To prevent accidental discharge, never release brake
without holding the handwheel firmly. Do not attempt
to grab the handwheel to stop an accidental discharge,
serious injury could result. Always make sure that the
brake is fully engaged after discharge of concrete and
before reloading the drum.

Operation
Capacities/Sample Mix/Cleaning
After discharge of concrete, immediately pour in the
required amount of water for the next batch.
NOTE: When servicing brake mechanism, bolt A
should be tightened so that approximately 17 - 18
pounds of force is required to release the brake. This
will prevent accidental discharge due to vibration.

CLEANING
For consistent performance, long life and continued
high quality mixing of cement, thoroughly clean the
mixer inside and out at the end of each day's operation.
Drum may be scoured by 2 minute operation with
gravel and water mixture. Discharge, then hose down
drum inside and outside. Keep mixer clean.
Before cleaning, shut off the engine or motor and
disconnect the spark plug wire or electric cord to
prevent accidental starting. Spray the mixer with
water before the mix dries to remove any
accumulations. Dried mix should be scraped out as
necessary. DO NOT beat on drum with shovel,
hammer or other device to break up accumulations of
dried mix, as this will dent and damage the drum.

Maintenance
NOTE: Cowl removed for clarity. Do not operate
mixer with cowl removed.
A. ENGINE - Daily check the oil levels in the
engine and engine reduction unit. The engine
warranty is VOID if run without oil. Since there
are many options available on this mixer, consult
the ENGINE MANUAL for specific recommendations as to oil level, oil type required and
frequency of oil changes required. For maximum
service life from the engine, follow those recommendations.
Schedule
E. YEARLY - Repack (4) tapered roller bearings in wheel hubs and replace wheel seals.
Install washer and nut. Torque to 20 ft. lbs.
back off one turn, torque to 7 ft. lbs. back off to

F. DO NOT lubricate pinion and ring gear.
They will collect abrasive materials and accelerate wear.
Lubricate diesel gearbox with SAE30W oil as
needed.
Use any Grade #1 lithium base grease for the
above applications.
* See Exploded Views with Parts Section of this
manual for exact location.
* Gearbox gasket kit P/N 23197.
B. * WEEKLY - Grease idler shaft pillow block
bearings on electric drive models.
*WEEKLY - Check diesel gearbox oil level.
Oil level should be visible at pipe plug. Lubricate
diesel gearbox with SAE30W to SAE80W oil as
needed.
