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/engine instructions for storage instructions.
2. Cover exposed metal surfaces with a thin coat of SAE 30 engine oil.
3. Lubricate per instructions under LUBRICATION section.
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/engine instructions. Start drum rotating clockwise by activating hydraulic valve
lever. 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.

water.
3. Add cement and two 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. Add remaining water as needed.
6. Mix batch for approximately one minute. Drum speed should be about 25 r.p.m. (NOTE: Mixing times may
change.)
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 stop lever. Dump concrete to either side by rotating handwheel in the direction
required. (NOTE: Mixing times may change.)
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.
