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.

*If crushed stone is used, decrease coarse aggregate by 3 lbs and increase sand by 3 lbs.
Metric conversion: 1 lb = 0.454 kg 10 lbs = 4.54 kg
1 in. = 25mm
Table 2. Proportions by Volume*
*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. 2.2A)
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.

3-LUBRICATION & STORAGE
Each day before operating, lubricate at the following points:
Engine/Motor – Refer to engine/motor operating instructions for all maintenance and
lubrication instructions and requirements.
GREASE FITTINGS:
Refer to Fig. 3.1A
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. 3.1A
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.
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 & STORAGE section.

5-SET-UP AND ASSEMBLY
This mixer is shipped partially disassembled and requires assembling.
1. Remove five ¼ x ½ hex hd. Cap screws, lock washers and hex nuts that secure
cover to the belt guard. Remove cover. (Save all hardware)
INSTALL MOTOR KIT PER INSTRUCTIONS
2. Replace the cover removed in step 1 and secure with hardware (saved). Tighten
securely.
3. Bolt the tilt wheel assembly (Ref. Let. AA thru AE) to the slotted steel angle
under the internal tilt gear (Ref. Let. AF). The tilt pinion will mesh with the
internal tilt gear when the steel tilt gear cover is in proper position. Tighten both
bolts securely.
4. Although the mixer was lubricated at the factory, now is the perfect time to
become familiar with points requiring regular service. Refer to the
LUBRICATION AND STORAGE section.
5. All nuts and cap screws should be checked and tightened during the first two
hours of use. Periodic checks should be made thereafter.
