OPERATION
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. The quality of the paste, in turn, is directly related to the amount of water mixed with the cement. For a
given amount of cement, as the amount of mixing water is reduced, the strength of the paste increases, making the concrete
stronger and more durable. Calculate the proportions of your mix components (cement, sand and coarse aggregate) accord-
ing to the job specifications.
LOADING THE MIXER
Start the mixer. 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 ce-
ment and last sand. For mixing instructions, refer to the mixing guide on page 17.
UNLOADING THE MIXER
Allow the entire mixture to mix for one full minute. Do not stop mixer from rotating. Dump concrete to either side by tilting the
handles in the direction required. Before reloading the mixer, slowly pour a pail of water over the lip of the drum, permitting
water to clean the inside of drum. When cleaned, dump water. Now you are ready for your next batch.
CLEANING THE MIXER
After each run of concrete has been poured, do the following: With the drum rotating, spray water into drum allowing the
water to run down the inside and outside of drum. Add one shovel full of coarse aggregate and permit this mixture to scour
the inside of drum for about two minutes. This practice will help keep the drum clean, which is essential in obtaining the best
mixing result. Never permit concrete to harden on either the inside or outside of drum.
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.
LUBRICATION & STORAGE
Lightly grease all moving parts – motor spindle, wheel axles and pedestal mounting shaft with SAE 30 engine oil.
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. Cover exposed metal surfaces with a thin coat of SAE 30 engine oil.
