Operation Towing the Machine Think Safety First Before towing the machine, read all the information and perform all the applicable procedures to in this section to ensure safe and proper towing. Carefully read all safety instructions and symbols in this manual, on the product decals, and other media supplied with the product. Knowing this information could help you or bystanders avoid injury. WARNING Towing the machine at high speed increases the risk of a hitch malfunction and tire failure.
Preparing the Machine for Towing 1. Shut off the engine and fuel valve. 2. Empty the drum. 3. Position the drum in the mix position (upright) and lock it. 4. Close the engine cowl and secure the cowl latches (Figure 14). g022324 Figure 14 5. If you have adjusted the axle to the narrow position (if equipped on your model), extend the axle; refer to Adjusting the Axle Width (page 19). 6. Inspect the tires; refer to Inspecting the Tires (page 39).
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. g035115 Figure 16 Note: Use a wrench to keep the bolt from spinning. Hitching a Pintle-Hitch Coupler g021177 Figure 18 1. Connecting links 3.
The corresponding turn-signal lights of the machine should illuminate. Adjusting the Axle Width Models with Adjustable Axles Only If your model is equipped with an adjustable axle (Figure 22), 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 g019927 Figure 19 1. Connecting link 3. Chain link 2. Safety chain mounting point on tow vehicle 4.
Preparing to Use the Machine g020019 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 27). 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. Figure 21 Opening the Cowl 1. Support point (2) 7.
Closing the Cowl Opening and Closing the Cowl Opening the Cowl g035135 Figure 25 Adding Fuel g035134 Figure 24 DANGER In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. • Fill the fuel tanks outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. • Never fill the fuel tanks inside an enclosed trailer.
• Do not store fuel either in the fuel tank or in fuel DANGER 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.

Move the choke lever to the ON position (Figure 28). Note: A warm or hot engine may not require choking. Performing Daily Maintenance 4. Move the throttle lever 1/3 of the way toward the MAX position. 5. Move the engine switch to the ON position (Figure 29).
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 (page 4). g019747 Figure 30 7. • Avoid direct contact of cement and concrete materials with skin and eyes. After the engine starts, gradually move the choke lever back to the OFF position.
7. Allow the paddles to mix the material until the ingredients have a uniform appearance. Note: If needed, add water or plaster, cement, or other binding material until the consistency of the batch is correct. Dumping the Material DANGER Contact with the mixing paddles could cause damage or injury. Never put your hands inside the drum while the engine is running.
4. With both hands on the dump handle, rotate it counterclockwise to discharge the contents of the drum (Figure 33). Note: Allow the machine to completely discharge the contents of the drum. 5. Rotate the dump handle clockwise until the drum latch locks the drum in the upright position (Figure 33). 6. After dumping a batch of material, clean the drum to prevent dried material from contaminating the next batch of material; refer to Cleaning the Drum (page 26).
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.
