Operation • When towing with a ball hitch, ensure that it is the proper size for the hitch coupler on the machine. • When towing with a pintle hitch, ensure that the Before Operation eye of the tow pole is the correct dimension for the pintle hook. Before Operation Safety • Inspect the hitch and coupling for wear. Do not General Safety • Check the air pressure of the tires on the towing tow the machine with damaged or worn hitches, couplings, chains, or other components.
Towing the Machine Preparing the Machine for Towing Before towing the machine, read all the information and perform all the applicable procedures to in this section to ensure safe and proper towing. WARNING Towing the machine at high speed increases the risk of a hitch malfunction and tire failure. Higher speeds also increase the momentum of the machine and braking distance. If the machine detaches from the tow vehicle at high speed, it could cause damage to property, or injury or death to bystanders.
g035115 Figure 15 Note: Use a wrench to keep the bolt from spinning. Hitching a Pintle-Hitch Coupler g035113 Figure 14 Hitching a Forged-Ball Coupler 1. Apply removable thread-locking compound to the threads of the coupler bolt to prevent the coupler handle from coming loose. Important: Apply thread-locking compound as needed in the future. 2. Apply chassis grease to the socket of the coupler and the area of the clamp that contacts the ball. 3. Hitch the machine as shown in Figure 15.
Connecting the Safety Chains to the Tow Vehicle 1. Pull the safety chain through the slots in the keyholes, so that the lengths on each side are equal. 2. Cross both lengths of chain under the tow pole. Note: Crossing the chains decreases the chances of the front of the machine dropping to the ground if the hitch does not hold the connection. g019927 Figure 18 1. Connecting link 3. Chain link 2. Safety chain mounting point on tow vehicle 4.
Closing the Cowl The corresponding turn-signal lights of the machine should illuminate. Preparing to Use the Machine 1. Park the machine on a level surface and disconnect the machine from the tow vehicle. 2. Ensure that all guards and paddles are in place and in good condition. 3. Perform all daily maintenance procedures prescribed in Maintenance (page 24). 4. Chock the front and back of the tires to prevent the machine from moving. 5. Move the drum to the upright position and lock it.
Important: To reduce starting problems, add fuel DANGER stabilizer/conditioner to fresh fuel as directed by the fuel-stabilizer/conditioner manufacturer. In certain conditions during fueling, static electricity can be released, causing a spark that 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.
– Safety glasses – Hearing protection – Substantial, slip-resistant footwear – Long pants – Shirt with long sleeves that are tight at the wrists – Tight-fitting gloves without drawstrings or loose cuffs • Wear appropriate clothing, including eye protection; long pants; substantial, slip-resistant footwear; and hearing protection. Tie back long hair and do not wear loose clothing or loose jewelry. • Do not operate the machine under ill, tired, or under the influence of alcohol or drugs.
• Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning. • Do not run an engine in an enclosed or poorly ventilated area. • Engine exhaust contains carbon monoxide, which is lethal if inhaled. Do not run the engine indoors or in an enclosed area. • Always shut off the engine and wait for all moving parts to stop before leaving the machine. g021103 Figure 25 • Use only accessories and attachments approved 1.
Adjusting the Axle Width Models with Adjustable Axles Only If your model is equipped with an adjustable axle (Figure 28), you can adjust the axle to the narrow position to move the machine through a narrow access point, such as the gate of a fence or the doorway of a building. WARNING The machine is not stable when towed with the axle in the narrow position. g020019 Tow the machine with the axle in the wide position. Figure 27 1.
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. • Avoid direct contact of cement and concrete materials with skin and eyes. DANGER g019873 Figure 29 This machine is capable of amputating hands. 1. OFF position • Stay in the operator’s position while the machine is running. 6.
7. Allow the paddles to mix the material until the ingredients have a uniform appearance. 4. Note: If needed, add water or plaster, cement, or other binding material until the consistency of the batch is correct. With both hands on the dump handle, rotate it counterclockwise to discharge the contents of the drum (Figure 31). Note: Allow the machine to completely discharge the contents of the drum. 5.
Maintenance WARNING Failure to properly maintain the machine could result in premature failure of machine systems, causing possible harm to you or bystanders. Keep the machine well maintained and in good working order as indicated in these instructions. Important: Refer to your engine operator's manual for additional maintenance procedures. Maintenance Safety • Shut off the machine and inspect it if an object enters the drum or causes another obstruction.
