OPERATION

65CMED & 95CMED

BEFORE STARTING

Mixers are shipped completely assembled and ready
for operation except for installation of the safety chain.

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

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. Consult the Lubrication Section of
the manual for the specific instructions if greasing is
required.

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. Loose hardware will contribute
to early component failure and poor performance.

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.

WARNING

FOLLOW THE GUIDELINES FOUND IN THE
SAFETY PRECAUTION SECTION OF THIS
MANUAL WHENEVER HANDLING GASOLINE.

TO START THE ENGINE/MOTOR

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.
If the engine doesn't start after (3) pulls, open choke
slightly to prevent flooding. 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. Always
operate the engine at full throttle when under load.

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 CMED mixers, consult
the ENGINE MANUAL included with this unit for
specific instructions.

- 14 -

OPERATION

65CMED & 95CMED

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 which
you plan on using 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

GASOLINE ENGINES - Depress kill 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 OR IF THE MIXER IS TO
BE TOWED TO A NEW LOCATION, 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.

By adding the water and gravel first the drum will be
kept clean and a good tumbling action 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).

To prevent accidental discharge, never release brake
without holding the handwheel firmly. Do not attempt
to grab 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 drum.

OPERATION

Start the engine / motor as instructed above and allow
gasoline engines to reach operating temperatures.
Close and latch the engine cowl. NEVER operate the
mixer with cowl open.

With drum operating between 20 - 25 RPM 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.

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.

gravel and water mixture. Discharge, then hose down
drum inside and out. Keep mixer clean.

ALWAYS DISCONNECT THE SPARK PLUG
WIRE OR ELECTRIC CORD WHEN CLEANING
INSIDE DRUM.

TOWING

Before attempting to tow this mixer, check the state
and local laws that apply to your intended route and
check the following:

1. Hitch attached to the towing vehicle
securely.

2. Towpole fully extended and bolted to mixer
securely.

3. Safety chain hooked up properly (see
illustration below or decal on mixer front
post).

INSTALLING CHAIN TO VEHICLE

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.

WARNING

NEVER POUR OR SPRAY WATER OVER THE
ENGINE OR MOTOR.

4. Lug nuts, wheel nuts and axle mount nuts
tight.

OPERATION

5. Main axle springs and small snubber
springs and bolts not broken or cracked.

6. Tires in good shape and at proper inflation
as follows:
Tire size B78 x 13 @ 35 P.S.I.

Refer to FRAME AND DRUM ASSEMBLY and
AXLE ASSEMBLY sections of the Service/Parts
Manual for parts identification and location.
