The following motor controls are found on all models: 1 3 Figure 10 1. Thermal-overload protector reset button 3. Power cord 2. On/Off switch g020669 Motor On/Off Switch Figure 11 The On/Off switch (Figure 11) allows the operator of the machine to start and stop the motor. This switch is located on the front of the motor.
Checking the Tires and Wheels Operation Service Interval: Before each use or daily—Inspect the tires and wheels. Important: Before operating, remove any debris from the machine. Ensure that the area is clear of people. WARNING Preparing to Tow the Machine Failure to maintain correct tire pressure may result in tire failure and loss of control, resulting in property damage and serious injury or death. Important: Ensure that your tow vehicle has towing capacity for the weight of the machine.
Hitching a Machine with a Stamped Ball Coupler the appropriate air pressure for the tires as installed at the factory. Important: Always check the information on the actual tires for the correct air pressure requirement. 1. Apply chassis grease to the socket of the coupler and the area of the clamp that contacts the ball. Oil the pivot points and sliding surfaces of the coupler with SAE 30 motor oil. Important: The most common cause of tire trouble is under-inflation. Maintain full air pressure. 2.
Hitching a Machine with a Forged Ball Coupler Hitching a Machine with a Pintle Hitch Tow Pole 1. Apply removable thread-locking compound to the threads of the coupler bolt to prevent the coupler handle from coming loose (Figure 17). 1. Remove the pin from the pintle hitch and open it (Figure 18). Important: Apply thread-locking compound as needed in the future. A 1 2 B 3 5 4 C D G019807 Figure 17 1. Coupler handle 4. Bolt 2.

Connecting the Lighting Wire Harness Note: Stow the excess chain inside the bottom of the front post by pushing it into the keyholes and latching the appropriate links into the keyhole slots. Connect the electrical plug of the machine with the electrical plug of the tow vehicle, as shown in Figure 21. 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.
Adjusting the Axle Width • Slide each side of the axle inward to the narrow WARNING • Mechanical or hydraulic jacks may fail to support the machine and cause serious injury. position (Figure 23). Slide each side of the axle outward to the wide (tow) position (Figure 23). 6. Align the holes of the inner axle with the holes of the outer axle. Use jack stands when supporting the machine. 7. Insert the bolts through the axle holes (Figure 23). 8.
Opening and Closing the Cowl • Ensure that the paddles are in place and in good condition. • Check all the grease fittings to ensure that the machine Opening the Cowl is properly lubricated. 1. At the side of the machine where the front cowl and rear cowl meet, grasp the latch and pull it off from the latch anchor on the rear cowl (Figure 24). • When preparing to mix material: 1. Move the machine to a level job-site surface. 2. Remove the machine from the tow vehicle. A B 3.
Powering the Machine Powering the Machine with a Portable Generator Connecting to a Power Source When using a portable generator as an electrical source, ensure that it meets the following power-output specifications: DANGER Contact with water while operating the product could cause electric shock, causing injury or death. • Do not handle the plug or the machine with wet hands or while standing in water. • Use only an extension cord recommended for outdoor cold-weather use.
Using the Clutch Lever 4. On the side of the junction box for the motor, press the reset button for the thermal-overload protector (Figure 25). Move the clutch lever clockwise to engage the clutch, and counterclockwise to disengage the clutch (Figure 26). 5. Connect the electrical plug for the machine to the power source. 6. Rotate the On/Off switch to the On position and ensure that the motor starts normally. 7. Rotate the On/Off switch to the Off position.
Using the Drum Mixing a Batch of Material in the Machine DANGER 1. Ensure that there is no old, loose material in the drum that can contaminate the batch of material; refer to Cleaning the Drum (page 21) and Dumping the Drum (page 20), then return the drum to the upright position. Contact with the mixing paddles could cause damage or injury. Never put your hands inside the drum at any time. Note: Ensure that the drum is in the mix position (upright) and the drum latch is engaged. Dumping the Drum 2.
6. After discharging a batch of material, clean the drum; refer to Cleaning the Drum (page 21). 3. Loosen the nuts and bolts that secure the paddle blades to the paddles (Figure 30). Note: This step will clean the paddles and drum between batches and prevent dried material from forming, and contaminating the next batch of material. Note: If necessary, tip the drum to the dump position to access the paddles.
Maintenance Important: Before performing any maintenance procedures, first stop the motor, wait 5 minutes to allow all moving parts to come to a complete stop and cool, and unplug the power cord. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 10 hours • Check the tension of the drive chain, and adjust it as needed. After the first 25 hours • Inspect the belts and adjust as necessary. Before each use or daily • Inspect the tires and wheels.
Lubrication Installing the Divider Plate 1. Guide the divider plate into position against the front cowl. Lubricating the Bearings and Seals Note: Start with the divider plate rotated slightly counterclockwise, and then rotate it clockwise while lowering it into position. Ensure that the divider plate is not backward. Service Interval: After each use—Lubricate the trunnions. Monthly—Lubricate the pillow-block bearings.
2. Pump grease into each fitting as follows: • For the pillow-block bearings, pump 1 shot of grease into each fitting (Figure 33). 1 • For the trunnions, pump several shots of grease into each fitting until it starts to ooze out of the bearing housing (Figure 33). Important: Pump grease in slowly and carefully to prevent damage to the bearing seals. 3. Wipe up any excess grease. Lubricating the Motor Bearings G021584 Figure 35 Service Interval: Every 6,000 hours 1.
Belt Maintenance A. Move the clutch lever to the Off position; refer to Controlling the Paddles (page 19). Servicing the Belts B. Inspecting the Belts Loosen the nuts and bolts that secure the motor to the motor deck (Figure 37). 1 1 Service Interval: After the first 25 hours—Inspect the belts and adjust as necessary. Every 40 hours—Inspect the belts and adjust as necessary. 1. Remove the divider plate; refer to Removing the Divider Plate (page 22). 2.

Slide the pillow-block bearings, along with the idler pulley and small sprocket, to the right to increase the chain tension, or to the left to decrease the chain tension.
Cleaning 2. Remove the lens (Figure 47). 3. Pull the bulb out of the socket (Figure 47). Cleaning the Machine 4. Push a new 168 bulb into the socket (Figure 47). 5. Install the lens and the 2 screws (Figure 47). Regular cleaning and washing will increase the life span of the machine. Clean the machine after each use, before the dirt hardens. Ensure that the motor is unplugged. Use care when using a high-pressure sprayer because it can damage warning decals, instruction signs, and the motor.
Storage Storing the Machine For storage over 30 days, prepare the machine as follows: 1. Move the On/Off switch to the Off position, and unplug the power cord. 2. Remove dirt and grime from the external parts of the entire machine, especially the motor. Important: You can wash the machine with mild detergent and water. 3. Grease the machine; refer to Lubricating the Bearings and Seals (page 23) and Lubricating the Drive Chain (page 24). 4. Check and tighten all bolts, nuts, and screws.
