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.

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.
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.
