SAFETY INSTRUCTIONS

SAFETY PRECAUTIONS:

This is the industry’s safety alert symbol. This symbol calls attention to items or
operations that could be dangerous. This symbol can be found throughout this manual
and on safety decals on the mixer. Read these messages carefully.

The following precautions are suggested to help prevent accidents. Read and
practice the following precautions before operating this equipment. Equipment
should be operated only by those who are responsible and have been properly
instructed.

1. Read all operating and maintenance instructions before operating or servicing

mixer. Test run empty prior to actual use.

2. A mixer is only as safe as its operator. Give complete and undivided attention to

the operation of the mixer.

3. Know how to stop the mixer and the engine instantly.

4. Always have all guards and safety devices attached and in place before operating

mixer. Close engine housing during operation.

5. Keep inexperienced and unauthorized people away from the mixer at all times.

6. Never leave the mixer unattended while it is running.

7. Shut off engine or disconnect the electric motor before making any adjustments or

putting hands or tools in the drum.

8. Do not overfill the drum. Do not exceed the mixer’s rated capacity.

9. Do not smoke while refueling the engine. Shut off the engine and allow it to cool

before refueling. Do not spill fuel.

10. Block mixer wheels when mixing.

11. Use safety chains while towing mixer.

12. Keep the mixer in good operating condition. Loose or damaged parts are

dangerous.

13. Avoid loose clothing that could get caught in moving parts or on control levers.

14. Do not add material to the drum while stopped. Start the drum before adding

material.

15. Keep all warning, caution and safety instruction labels in good condition.

Replace missing, damaged or illegible labels.

TOWING & SAFETY CHAINS:

For transporting the mixer, slide the tow pole out as far as possible and insert the locking
pin. When operating the mixer, slide the tow pole in and lock it in place.
Make sure drum is locked in position and engine housing is closed and secured.
Cross the safety chains under the tow pole and fasten them to the tow vehicle. (fig.1)

NOTE! Safety chain length may need to be altered for proper connection to
tow vehicle. Reposition the hooks, DO NOT cut chain.

Allow enough slack to permit proper vehicle turning while keeping chains snug enough
to prevent tow pole from contacting the ground in case the hitch uncouples.

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 (item 4, fig3)
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 ½ to 2/3 full to prevent overheating.

6

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.

LUBRICATION FREQUENCY CHART:

# ITEM FREQUENCY FIGURE CODE PLACES
1 Yoke Bearing Casting weekly 3 grease 2
2 Handwheel Hub weekly 4 grease 1
3 Drum Tilt Brake Bearing Casting weekly 4 grease 1
4 Drive Shaft & Jackshaft weekly 4 grease 1
5 Drum Shaft Tube yearly 3 grease 1
6 Wheel Bearings yearly 1 grease 2
7 Drive Chain monthly 4 oil 1

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.

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.
