WARNING Towing the machine with material in the drum increases the risk of a hitch malfunction and tire failure. In addition, material could bounce out of the drum and hit other vehicles and/or people. Material in the drum increases the weight, which affects momentum and braking distance. Do not tow the machine with material in the drum. • Review and understand the Safe Operating Practices (page 4). • Test the brakes of the tow vehicle before towing.
g035115 Figure 16 Note: Use a wrench to keep the bolt from spinning. Hitching a Pintle-Hitch Coupler g035113 Figure 15 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 16.
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 19 1. Connecting link 3. Chain link 2. Safety chain mounting point on tow vehicle 4.
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 The machine is not stable when towed with the axle in the narrow position. g029390 Figure 21 Tow the machine with the axle in the wide position. 1.
Preparing to Use the Machine Closing the Cowl 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 26). 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.
• 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.
Starting the Engine 1. Ensure that the clutch lever is in the OFF position. 2. Move the fuel valve to the OPEN position, all the way to the right (Figure 27). g020679 Figure 26 1. Maximum fuel level g019815 Figure 27 4. Install the fuel cap securely (Figure 25). 5. Wipe up any spilled fuel. 1. Choke lever 2. Fuel valve 3. Performing Daily Maintenance 3. Throttle lever Move the choke lever to the ON position (Figure 27). Note: A warm or hot engine may not require choking.
6. Pull the starter handle lightly until you feel resistance, then pull the handle briskly (Figure 29). Return the starter handle gently. 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 away 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.
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 32). 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 32). 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 25).
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. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 20 hours • Change the reduction-case oil.
