    • Use summer-grade diesel fuel (Number 2-D) at temperatures above -7°C (20°F) and winter-grade diesel fuel (Number 1-D or Number 1-D/2-D blend) below -7°C (20°F ).

    • Never mix kerosene, used engine oil, or residual fuels with the diesel fuel.

    • Do not store fuel either in the fuel tank or fuel containers over the winter.

    • Fuel additives are not recommended. Some fuel additives may cause poor engine performance.

    Danger

    In certain conditions, diesel fuel is extremely flammable and highly explosive. A fire or explosion from diesel can burn you and others and can damage property.

    Use only diesel fuel. Filling the fuel tank with gasoline may result in a fire.

    • Fill the fuel tank and store fuel in a well-ventilated area.

    • Do not refuel the fuel tank while the engine is running.

    • Do not fill the fuel tank completely full. Add fuel until it is at the same level as the red ring. This empty space in the tank allows fuel to expand.

    • Never smoke when handling fuel, and stay away from an open flame or where fuel may be ignited by a spark.

    • Store diesel in an approved container and keep it out of the reach of children. Do not buy more than a 30-day supply of fuel.

    • Do not operate without the entire exhaust system in place and in proper working condition.

    Danger

    In certain conditions during fueling, static electricity can be released, causing a spark which can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property.

    • Always place fuel containers on the ground away from your vehicle before filling.

    • Do not fill fuel containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

    • When practical, remove fuel-powered equipment from the truck or trailer and fuel the equipment with the wheels on the ground.

    • If this is not possible, then refuel such equipment on a truck or trailer from a portable container rather than from a fuel-dispenser nozzle.

    • If you must use a fuel dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

    Warning

    Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

    • Avoid prolonged breathing of vapors.

    • Keep your face away from the nozzle and the fuel tank or conditioner opening.

    • Keep fuel away from your eyes and skin.

    Using the Machine

    Danger

    This machine is capable of amputating hands.

    • Stay in the operator’s position while the machine is running.

    • Keep all bystanders a safe distance from the machine.

    • Stop the machine immediately if any people or animals enter the work area.

    • Never place any part of your body into a position that causes an unsafe operating condition.

    1. Ensure that the machine is on level ground and that the surrounding area is clear of obstacles.

      Note: Disconnect the machine from the tow vehicle and chock the front and back of both tires to prevent any movement.

    2. Make sure that you read all the recommendations from the Safety section; refer to Safe Operating Practices before using the machine.

    3. Start the engine and close the engine cowl. Allow the engine to warm up at idle for 2 minutes; refer to Starting the Engine.

    4. Use the handwheel to move the drum into an upright, slightly tilted position to allow access for pouring materials into the drum.

      Note: This position also allows the mixing paddles to mix the materials more effectively.

    5. Push the drum-tilt brake down to lock the drum into position and avoid accidentally dumping the material.

    Important: If you need to stop the machine, use the engine-speed-control handle located on the cowl; refer to Engine Speed Control Handle.

    Mixing the Material

    Danger

    Eye and skin contact with concrete materials and breathing the dust involved is hazardous to your health.

    • Ensure that there is adequate air ventilation.

    • Wear a dust mask to prevent inhalation of dust while using the machine; refer to Safe Operating Practices.

    • Avoid direct contact of cement and concrete materials with skin and eyes.

    Important: Do not add more material than the batch capacity of the machine; refer to Specifications.

    Note: Follow the manufacturer’s instructions that are printed on the packaging of the product.

    Concrete has the following 4 basic ingredients:

    • Sand

    • Gravel

    • Portland cement

    • Water

    Depending on the application, you can use different ratios of these 4 ingredients.

    There are many variations of concrete mix recipes, depending on the application. It is important to use the appropriate quantity of water. Using too little water results in dry areas in the mix, but using too much water will result in weaker concrete. The amount of water needed varies depending on the moisture content of the sand and gravel. The mix should have a thickness similar that of peanut butter.

    Keep the poured concrete damp for several days to obtain proper curing. Evaporation results in weaker concrete. Concrete cures through hydration, a reaction between water and cement.

    Mixing Pre-Mix Concrete

    1. Ensure that the tilt brake is fully engaged and that the drum is operating at full speed.

    2. Pour water into the drum.

    3. Add the required amount of dry pre-mix.

    4. Allow the drum to turn while the mix reaches the appropriate consistency.

    Mixing Sand, Gravel, and Cement

    The typical ratio for mixing concrete is 1 part Portland cement, 2 parts sand, and 3 parts gravel.

    1. Ensure that the tilt brake is fully engaged and that the drum is operating at full speed.

    2. Pour water into the drum.

    3. Add the required amount of gravel.

    4. Add the required amount of Portland cement.

    5. Add the required amount of sand.

    6. Allow the drum to turn while the mix reaches the appropriate consistency.

    Note: Adding water and gravel before cement and sand allows the mix left in the drum from the previous batch to be tumbled off the drum and paddles and into the next batch.

    Using the Drum

    Danger

    Contact with the mixing paddles could cause damage or injury.

    Never put your hands inside the drum at any time.

    Dumping the Drum

    Note: When dumping a batch of material, leave the engine running so that the rotating drum helps dump the material.

    1. Align a wheelbarrow or similar container of adequate capacity in the path of the drum opening.

    2. While the drum is turning, firmly grasp the handwheel with one hand.

    3. Using your other hand, pull up on the drum-tilt brake handle to release the brake.

    4. Using both hands, slowly turn the handwheel, allowing the drum to tilt in the desired direction and dump the desired amount of material.

    5. Turn the handwheel in the opposite direction to return the drum into an upright position.

    6. Push down on the drum-tilt brake to lock the drum into position, avoiding accidental discharging of concrete mix.

    7. After dumping a batch of material, clean the drum; refer to Cleaning the Drum.

      Note: This step will clean the paddles and drum between batches and prevent dried material from forming and contaminating the next batch of material.
