REPORTING SAFETY DEFECTS

If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Crown Construction Equipment.

If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in any individual problems between you, your dealer, or Crown Construction Equipment.

To contact NHTSA you may either call the Auto Safety Hotline toll free at

1-800-424-9393 (366-0123 in Washington, DC area) or write to:

You can also obtain other information about motor vehicle safety from the Hotline.

WARNING

CALIFORNIA - Proposition 65 Warning

Engine exhaust and some of its constituents and some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to the State of California to cause cancer, birth defects and other reproductive harm.

Some examples of these chemicals are:

Lead from lead-based paints

Crystalline silica from bricks

Cement and other masonry products

Arsenic and chromium from chemically treated lumber

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals:

ALWAYS work in a well ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

4.1 TO THE NEW OPERATOR OR OWNER

The Crown Construction Equipment Concrete Mixer is designed to efficiently combine water, aggregate and cement into a mixture for forming concrete. It is the responsibility of the operator to be familiar with the machine before starting.

It is the responsibility of the owner or operator to read this manual before starting. Follow all safety instructions exactly. Safety is everyone's business. By following recommended procedures, a safe working environment is provided for the operator, bystanders and the environment.

Many features incorporated into this machine are the result of suggestions made by customers like you.

Read this manual carefully to learn how to operate the machine safely and how to set it to provide maximum mixing efficiency. By following the operating instructions in conjunction with a good maintenance program, your

Mixer will provide many years of trouble-free service.

11

4.2 HOW THE MACHINE WORKS

The Concrete Mixer consists of a large rotating drum with internal paddles for combining cement, aggregate and water into a mixture for forming concrete. The enclosure on the back end houses the gas engine for turning the mixing drum. A set of pulleys and drive belt within the enclosure transmits rotational power to the drum.

bly allows the operator to tilt the drum to the required position for mixing and emptying. An extendable hitch on the front of the frame allows the hitch to extend for towing and retracts during operation.

7. Emergency Stopping:

If an emergency arises, stop the machine by turning the power switch OFF or by pushing the Emergency Stop switch in.

8. Machine placement:

Always place the Mixer in a location so the operator has easy access to the mixture ingredients when adding to the mixing drum. Always position to provide adequate clearance for the machine or equipment removing the concrete mixture from the mixing drum. On the electric motor models, route the power cord out of the way to prevent damage.

Do not run the mixture in an explosive atmosphere or in a poorly ventilated or enclosed area.

9. Filling:

When mixing concrete, follow this procedure: a. Clear the working area of unauthorized personnel.

b. Start the mixer.

c. Add half the required amount of water into the mixing drum.

d. Add a small amount of aggregate into the drum.

e. Add the cement required for the batch.

f. Add the rest of the water.

g. Add the aggregate until the desired workability is obtained.

 mixture.

j. Move the drum back into its mixing position and immediately add half the water for the next batch. This will help to keep the drum and mixing paddles clean and prevent lumps from forming in the concrete.

10. Mixing time:

After all the ingredients have been added to the drum, allow time for the material to reach a uniform color and consistency. Watch the color and consistency of the mixture as the drum is turning.

When the entire mixture becomes a deep khaki green color, it means the cement is uniformly distributed throughout the mixture and can be discharged. If the mixture is not uniform, the concrete will have weak spots.

11. Emptying drum:

All Mixers are equipped with a lock for anchoring the drum at a pre-determined angle. Move the wheelbarrow or other concrete receiver up to the side of the Mixer. To empty the drum:

NOTE

Add aggregate a little at a time until the desired consistency is obtained.

a. C-3C Model:

Lift the tilt lever to release the load on the anchor pin. Pull the spring-loading anchor pin out of the hole in the anchor disc. Slowly lower the drum to discharge the mixture into the wheelbarrow. Lift the drum back into its mixing position and secure with the lock pin.

h. Mix until there is an even consistency throughout the mixture. Look into the drum. When the entire mixture is an even khaki green color, the cement is evenly distributed throughout the mixture.

i. Slowly tilt the drum down to discharge the

Emergency Stop Switch

20 b. C-6C and C-9C Models:

Turn the tilt wheel to release the load on the anchor pin. Pull and lift the anchor lock bracket to release the lock. Use the tilt wheel to slowly lower the drum into its discharge position. Do not engage the anchor lock unless the drum has stopped moving. Raise the drum back into its mixing position and secure with the lock after the drum has been emptied.

12. Cleaning:

Under normal operating conditions, adding water and some aggregate to the drum immediately after emptying will wash and clean the mixing paddles and the inside of the drum and keep them clean. If a slow build up of residue is occurring, add water and coarse aggregate to the drum at the end of the working day and let it run for 15 minutes. If the coarse aggregate does not remove the build-up, disable the machine by unplugging the power cord or disconnecting the spark plug wire and using a hammer and chisel to remove the lumps.

If your machine is equipped with a poly drum, use a rubber mallet to strike the outside and break the build-up loose. If you do not have a rubber mallet, lay a 2 x 4 against the drum. Hit the 2 x 4 with a hammer. The wood will provide protection for the poly drum.

At the end of the working day, thoroughly wash the inside of the drum and the outside of the machine to remove any residue build-up or clumps. Do not get water on the electric motor or gas engine.

13. Drum speed:

The best mixing action occurs when the drum is turning 18 to 24 RPM. Do not operate outside of this speed range. Increasing the drum speed does not significantly change mixing characteristics. Mixing time is much more important and the mixture must be thoroughly blended to obtain uniform and consistent concrete.

14. Capacities:

Each model has its own specified capacity.

When that capacity is exceeded, the excess spills out of the drum making a mess of the working area and increases the required time for mixing. It is recommended to use an additional mixer if more mixing capacity is required.

16. Material Requirement Calculations:

Example:

A concrete driveway 100 feet long (30m) by 10 feet wide (3M) by 6 inches deep (150 mm).

a. Determine volume of concrete required Length x Width X Depth

= 100 x 10 x 0.5 = 500 cu.ft.

(=30 x 3 x .15 = 13.5 cu. metres) b. Select mix required for the application (refer to table above) in this case a 1:2:3 mix by volume is suitable.

c. Calculate the material required from the values in the table.

Cement 18.5 x 6-1/2 = 120 sacks

For driveways, sidewalks, livestock floors, paved yards, and other work where a non-skid surface is required, a wood float or belt finish is recommended. For such a finish the fresh concrete is struck off flush with the top of the forms as soon as it is placed, then the wood float is used to make an even surface.

The final finishing is delayed until the concrete hardens enough to become quite stiff, then finishing is done with a wood float which results in a uniform gritty surface.

This time the length of the side-wise strokes of the strip of canvas or rubber should not be more than

4 inches and the forward movement should be slightly faster than the first time over. Surface water should be avoided. However, when there is a small amount present, it should be allowed to evaporate before finishing. If there is considerable water, it is removed with a broom, belt, float, or other convenient means. It is never good practice to sprinkle dry cement or a mixture of cement and fine aggregate on fresh concrete to take up surface water as such fine material will form a layer on the surface that is likely to dust or hair check when the concrete hardens.

A final finish on driveways, pavements, and similar work can be produced with a strip of canvas or rubber, not less than 6 nor more the 12 inches wide, and at least 2 feet longer than the width of the slab being finished. This is used immediately after the wood float and is moved back and forth in a sideways direction as it is advanced. For the first time, vigorous 12 inch strokes cross-wise of the slab are used. Advance slowly along the slab as the surface is made smooth and even. Repeat

For a smooth finish such as is required for feed mangers, poultry house floors, dairy barn, gutters, basement floors, and similar work, follow the wood float with a steel trowel only after the surface has become quite stiff. Excessive trowelling or the use of the steel trowel before the mix has become stiff forces the larger hard wearing particles of aggregate to the bottom, leaving a collection of the paste and fine, weak particles on the surface. The excess water near the surface evaporates, leaving a thin honeycombed layer of weak material just where toughness and extra strength are required. Excessive cracking, spalling and dusting may result. Use the steel trowel sparingly.

23

19. Curing concrete:

Concrete hardens because of chemical reaction between the cement and water. This reaction take place only as long as the temperatures are favourable and moisture is present to hydrate the cement. Maintaining freshly placed concrete in a moist condition to promote hardening and strength increase is called curing.

Moist curing greatly increases the strength of concrete. Tests shown that concrete damp cured for 7 days will be approximately 50% stronger than similar concrete which is permitted to dry out. Concrete damp cured for 1 month will be approximately 100 percent stronger than similar concrete kept in dry air. Tests show that the strength of damp cured concrete is influenced by the length of time the concrete is kept damp; also that it hardens faster at higher temperatures.

Concrete cured at 21°C (70°F) generally hardens more than twice as fast as concrete cured at a temperature slightly above freezing. At high curing temperatures, the concrete cures rapidly giving a higher than normal initial strength. However after approximately 30 days, the strength of concrete cured at 70°F (21°C) gradually exceeds the strength of that cured at higher temperatures.

Thorough moist curing aids in producing water tight concrete. As the cement paste in concrete hardens, additional solid matter is formed, which closes off the space between the cement particles through which water might otherwise seep. The more complete the hydration of the hardening process, the denser and more water tight becomes the cement paste.

Increase resistance to wear also results from proper curing, which emphasizes the importance of damp curing floors, pavements, and other surfaces subject to wear.

Continuous damp curing, particularly in the early stages of hardening, helps to get a hard, dense surface and to prevent checking and dusting.

20. Common methods used in curing concrete:

Cover with wet burlap, canvas, sand or straw coverings as soon as it can be done without marring the surface. Keep the covering continuously wet by sprinkling. When a cover is not used, wetting should be started as soon as possible after finishing, and the surface should not be permitted to dry during the curing period. Floors, sidewalks, pavements, and other flat surfaces require careful attention as moisture is lost very rapidly by evaporation due to the relatively large exposed surface. Ponding (flooring) is a good method of curing flat surfaces. With this method the surface to be cured is surrounded by small earth dikes and then kept

24

Walls and other vertical surfaces can be protected by leaving the forms in place temporarily, of by hanging canvas or burlap over them. Such coverings are kept constantly moist by sprinkling.

Curing should continue for at least 7 days, and for longer periods of time when it is practical to do so.

21. Ring Gear:

It is recommended that a light coating of grease be applied to the ring gear and driving sprocket every week to reduce wear.

22. Operating hints: a. Keep the working area as clean and dry as possible to prevent slipping and tripping.

b. Provide sufficient space around the machine for adding material to the drum and removing the mixture.

c. Always add the materials in the same ratio to give a uniform mixture for concrete.

d. Provide sufficient time to thoroughly combine the mixture to a uniform consistency before discharging from the drum.

e. The water requirements for the mixture can vary depending on moisture content of the aggregate. Vary the amount of water in the mixture to give the consistency of the concrete desired.

Every engine is shipped from the engine factory without gas or oil because of fire hazards during shipping. They are all set with a high idle of 3500 RPM. Since no fluids are added at the Mixer factory, the RPM is not reset. When the Mixer is delivered, the fluids must be added and the RPM reset. To reset the RPM, follow this procedure:

1. Read the engine manual supplied with the machine.

2. Add fuel and the specified motor oil to the crankcase.

3. Start the engine and run at wide open throttle.

4. Use a screwdriver to reset the high idle stop screw.

NOTE

It may be helpful to remove air cleaner cover to provide access to screw.

Fig. 28 ENGINE SPEED SETTING (TYPICAL)

5. Use the drum revolutions to determine engine RPM setting. Set the engine RPM to give a drum rotation speed of 18-20 RPM when the drum is loaded.

6. Reset if the speed changes as required.

WARNING

WARNING



5.2.4 BELT TENSION AND ALIGNMENT

A drive belt and pulley system transmits power from the motor or engine to the pinion gear for rotating the drum. The tension must be maintained to prevent slipping and the pulleys aligned to prevent belt wear. To set the tension and alignment, follow this procedure:

1. Unlatch and open hood.

2. Disable power source by unplugging power cord or disconnecting spark plug wire.

3. Loosen motor or engine mounting platform bolts (from back side).

4. Slide or tap platform down to tighten belt.

5. The belt is properly tensioned when the mid-span deflects 1/4 inch (6 mm) when pushed on with a 10 lb force.

6. Tighten platform mounting bolts to their specified torque.

7. Align the pulleys by loosening the motor or engine mounting bolts.

8. Slide or tap the power unit into position to align the pulleys.

9. Tighten power unit mounting bolts to their specified torque.

10. Close and secure the hood.

5.2.5 PADDLE REPLACEMENT

Each machine is equipped with 3 equally spaced paddles on the inside of the drum. After extended use, they will wear. To replace paddles, follow this procedure:

1. Open hood and disable power source by unplugging power cord or removing spark plug wire.

2. Remove paddle mounting bolts.

3. Remove old paddles and install new ones.

4. Install mounting bolts and tighten to their specified torque.
