Motor Controls The following motor controls are found on all models: 2 1 1 3 G022280 Figure 10 1. Thermal-overload protector reset button 3. Power cord 2. On/Off switch g020669 Figure 11 Motor On/Off Switch 1. Motor On/Off switch 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. It is marked (ON) and (OFF). Rotate the On/Off switch to the On position to start and run 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.

Extending the Axle 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. WARNING 2. Cross both lengths of chain under the tow pole. The machine is not stable when towing it with the axle in the narrow position. 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. Tow the machine with the axle in the wide position.
4. Remove the bolts and nuts that secure the inner axle to the outer axle (Figure 22). 1 2 3 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. 3 4 Do not tow the machine with material in the drum. • Review and understand Safe Operating Practices (page 3).
Opening and Closing the Cowl Powering the Machine Opening the Cowl Connecting to a Power Source 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 23). A DANGER Contact with water while operating the product could cause electric shock, causing injury or death. B • Do not handle the plug or the machine with wet hands or while standing in water.
Powering the Machine with a Portable Generator 4. On the side of the junction box for the motor, press the reset button for the thermal-overload protector (Figure 24). When using a portable generator as an electrical source, ensure the following power output specifications: Model Voltage Amperes Kilowatt hour Frequency/ phase 68012 115 V / 230 V 19 A / 9.5 A 2.2 to 2.3 Kw 60 Hz / single 68018 115 V / 230 V 19 A / 9.5 A 2.2 to 2.3 Kw 60 Hz / single 68019 115 V / 230 V 24 A / 12 A 2.
Using the Clutch Lever Mixing a Batch of Material in the Machine Move the clutch lever clockwise to engage the clutch, and counterclockwise to disengage the clutch (Figure 25). 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 19) and Dumping the Drum (page 19), then return the drum to the upright position. Note: Ensure that the drum is in the mix position (upright) and the drum latch is engaged. 2.
Using the Drum 6. After discharging a batch of material, clean the drum; refer to Cleaning the Drum (page 19). DANGER Note: This step will clean the paddles and drum between batches and prevent dried material from forming, and contaminating the next batch of material. Contact with the mixing paddles could cause damage or injury. Never put your hands inside the drum at any time.
3. Loosen the nuts and bolts that secure the paddle blades to the paddles (Figure 29). Note: If necessary, tip the drum to the dump position to access the paddles. 1 2 G022160 Figure 29 1. Paddle blade 2. Nut and bolt 4. Move the paddle blades to the preferred position, and tighten the nuts and bolts to secure the blades to the paddles. Note: Ensure that the clutch lever is in the Off position, and rotate the paddles as needed. 5.
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 32). 1 • For the trunnions, pump several shots of grease into each fitting until it starts to ooze out of the bearing housing (Figure 32). 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 34 Service Interval: Every 6,000 hours 1.
Belt Maintenance A. Move the clutch lever to the Off position; refer to Controlling the Paddles (page 17). Servicing the Belts B. Inspecting the Belts Loosen the nuts and bolts that secure the motor to the motor deck (Figure 36). 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 21). 2.
