MIXING INSTRUCTIONS:
1. Start the drum rotating.
2. Add water.
3. Add cement and one shovelful of coarse aggregate. The coarse aggregate will
break up any lumps in the cement.
4. Add remaining aggregate: crushed stone, pit-run gravel or sand.
5. Mix batch for approximately one minute. Drum speed should be about 25 r.p.m.
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.
