PRIOR TO START UP

1. Examine the mixer carefully to make sure there was no damage during shipment or since the last use. Report any
damage immediately to the transportation company. Repair any damage before using the mixer.

2. Check for free rotation of the mixer drum yoke by rotating the drum through one complete dump-charge-dump cycle.
Make sure no foreign objects or tools are in the drum before starting the motor.

3. Check the engine oil. Fill as required. Refer to the engine manual for oil specifications.

4. Fill the fuel tank with fresh, clean fuel. Refer to the engine manual for fuel specifications.

5. Grease all fittings as called out in the lubrication specifications.

6. Start the motor and check for smooth operation of the drum, ring gear, and pinion.

Note: After initial 10 hours of operations, check chain/belts for proper tension and sprockets/pulleys for alignment. Check

these items monthly to prevent premature wear/failure.

LUBRICATION

Use lithium based grade 2 multi-purpose grease.

Drum Shaft Tube:

Drum shaft lubrication can be performed by removing the 1/8” pipe plug and installing the appropriate
grease fitting. Greasing should be done yearly.

Yoke Bearing Hangers:

Yoke bearing hangers are located on the yoke ends and are equipped with grease fittings. These bearings should be
greased weekly.

Wheel Bearings:

Grease wheel bearings once per year. Thoroughly remove old grease from bearings and spindle before repacking.
Pack bearings 1/2 to 2/3 full to prevent overheating.
Drum Tilt Brake Bearing:
The brake bearing casting is located near the front of the mixer and should be greased weekly.
Handwheel Bearing:
The handwheel hub bearing is located on the front of the mixer, behind the handwheel. This bearing should be
greased weekly.

WARNING: DO NOT GREASE BRAKE BAND OR OUTER BRAKING SURFACE OF TILT GEAR.

Jack Shaft Bearings:

Pillow block style bearings are used on the drive train counter shaft. These bearings should be greased weekly.

Drive Chain:

The drive chain should be lubricated monthly with SAE #20 or SAE #30 oil. Apply the oil between the side plates.

Engine/Motor:

Refer to the manufacturer’s engine or motor operating instructions for all maintenance and lubrication requirements and
instructions.

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.

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)
according to the job specifications.

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.

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.

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. Mix
batch for approximately one minute. Drum speed should be about 25 r.p.m. When
cleaned, dump water. Now you are ready for your next batch.

Fig. 1

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 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.

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.
