PRIOR TO START UP
1. Examine the mixer carefully to make sure there was no damage during shipment or since the last use. Report any
damage immediately to the transportation company. Repair any damage before using the mixer.
2. Check for free rotation of the mixer drum yoke by rotating the drum through one complete dump-charge-dump cycle.
Make sure no foreign objects or tools are in the drum before starting the motor.
3. Start the motor and check for smooth operation of the drum.
STORAGE
For short term storage, clean the mixer and store in a dry place. If the mixer is not to be used for an extended period of
time, service mixer completely and store it in a dry place.
1. Refer to motor instructions for storage instructions.
2. Cover exposed metal surfaces with a thin coat of SAE 30 engine oil.
GETTING READY FOR MIXING
Lay out forms for your concrete floor, patio, driveway, sidewalk, etc. The quality of concrete is directly related to the quality of
the cement paste. Calculate the proportions of your mix components (cement, sand and coarse aggregate) according to the
job specifications.
LOADING THE MIXER
Start the mixer. Refer to motor instructions. After drum has started rotating, pour about half of the water in the drum.
NOTE: The drum may leak slightly when first used. This will stop after a few batches. Add aggregate (gravel) first then
cement second and sand last. Then add remaining water as needed.
MIXING INSTRUCTIONS
1. Tip and lock the drum in inclined position.
2. Start the drum rotating.
3. Add

/

water.
4. Add cement and one shovelful of coarse aggregate. The coarse aggregate will break up any lumps in the cement.
5. Add remaining aggregate: crushed stone, pit-run gravel or sand.
6. Add remaining water as needed.
7. Mix batch for approximately one minute. Drum speed should be about 25 r.p.m. (NOTE: Mixing times may vary slightly.)
UNLOADING THE MIXER
Allow the entire mixture to mix for one full minute. Do not stop mixer from rotating.
Hold the tilt handle and unlock the tilt lock pin. Dump concrete to discharge side.
(NOTE: Mixing times may vary slightly.)
EXTENSION CORDS-ELECTRIC MOTOR
The following size extension cords should be used for this mixer: length of cord, up to 100 ft-14 gauge wire; up to 200 ft-12
gauge wire; up to 300 ft – 10 gauge wire; up to 400 ft – 8 gauge wire.
CARE OF MIXER
It is important to keep the inside of the mixing drum free of hardened concrete. After discharging the last batch of concrete
each day, add a pailful of water and two shovelfuls of gravel to the drum. This will scour the inside of the drum. Mix for
about two minutes, discharge and rinse the drum with water. Never permit concrete to harden on either the inside or outside
of drum.
