1-SAFETY PRECAUTIONS

THE FOLLOWING PRECAUTIONS ARE SUGGESTED TO HELP
PREVENT ACCIDENTS. A CAREFUL OPERATOR IS THE BEST
OPERATOR. MOST ACCIDENTS CAN BE AVOIDED BY OBSERVING
CERTAIN PRECAUTIONS. READ AND TAKE THE FOLLOWING
PRECAUTIONS BEFORE OPERATING THIS EQUIPMENT TO HELP
PREVENT ACCIDENTS. EQUIPMENT SHOULD BE OPERATED ONLY BY
THOSE WHO ARE RESPONSIBLE AND INSTRUCTED TO DO SO.

§ Read all mixer and electric motor/engine instructions before operation.

§ Use a grounded, three wire plug-in for all mixers using an electric motor or an

electric starting engine.

§ Do not use mixer in standing water if powered by an electric motor or an electric

starting engine.

§ Do not over-fill the mixer. There should not be any liquid running out of the mixer

drum.

§ Know how to stop the motor/engine instantly.

§ Keep hands and feet away from all moving parts.

§ If you are unfamiliar with the mixer, test run the empty mixer prior to actual use.

§ Never charge or fill unit prior to starting, as the over-load initially encountered could

damage the motor/engine.

§ Stop motor/engine whenever you leave or clean the unit. Disconnect power cord on

electric motor.

§ Never operate mixer without guards being properly positioned and secure.

§ Avoid spilling gasoline. Never fill tank while the engine is running or while you are

smoking.

§ Open doors if engine is running in an enclosed area. Exhaust fumes are dangerous.

§ Store gasoline in safe container. Store the container in a cool, dry place. Do not

keep in the house or near heating appliances.

§ Never reach into drum while mixer is running.

§ Keep mixer in good operating condition. Loose or damaged parts are dangerous and

should be tightened or replaced before operating.

§ Keep bystanders, especially children, away from mixer while operating.

DRUM SPEED

The mixer drum should revolve between 20 and 25 R.P.M.’s for best results in
mixing concrete. To obtain this speed using a 1725/1800 R.P.M. electric motor, use a
2” diameter “A” section V-pulley.

If using a 6 to 1 speed reduction 3 H.P. gasoline engine, use a 6 ¼” diameter “A”
section V-pulley.

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.

The proportions by weight given in Table 1 can be used as a starting point to make 1
cu. Ft. (0.028 m3) of strong, durable concrete. The proportions given in Table 2 are
volumetric; 1 bag of cement is equal to 1 cu. ft. (0.28 m3) and weighs 94 lbs.
(42.6 kg). The Canadian bag of cement has a net mass of 40 kg.

The proportions are only a guide and may need adjustments to give a workable mix
with locally available aggregates.

Table 1. Proportions by Weight to Make 1 Cu. Ft. of Concrete

Cement Sand aggregate Water Cement Sand aggregate Water

*If crushed stone is used, decrease coarse aggregate by 3 lbs and increase sand by 3 lbs.
Metric conversion: 1 lb = 0.121 kg 10 lbs = 4.54 kg

1 in. = 25mm
Table 2. Proportions by Volume*

Cement Sand aggregate Water Cement Sand aggregate Water

*The combined volume is approximately 2/3 of the sum of the original bulk volumes.

LOADING THE MIXER

Start the mixer. Refer to motor/engine instructions. After drum has started rotating, pour
about half of the water in the drum..

NOTE: The drum my leak slightly when first used. This will stop after a few batches.

Add aggregate (gravel) first then cement and last sand.

UNLOADING THE MIXER

Refer to Fig. 1
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 tilting the tilt
handle 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 permitting 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 ft­14 gauge wire; up to 200 ft-12 gauge wire; up to 300 ft – 10 gauge wire; up to 400 ft – 8
gauge wire.

Clean off grease fitting before greasing. Use pressure type grease gun. Grease lightly
with general purpose grease (2 to 3 pumps).

§ Drum Shaft Bearings (where used)

§ Drive shaft Bearings

§ Tilt Wheel Shaft Bearings (where used)

§ Brake Lever Shaft (where used)

OIL:
Refer to Fig. 2

Use SAE 30 engine oil.

§ Yoke Tilt Mechanism

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.
