Controls Dump Handle Become familiar with all the controls before you start the motor and operate the machine. Use the dump handle to rotate the drum to the dump position and to rotate the drum to the mix position (upright). Clutch Lever The clutch lever is used to engage and disengage motor power to the paddles. 1 G019875 Figure 9 Figure 7 1. Dump handle 1.
Motor Controls The following motor controls are found on all models: 2 1 1 3 G022280 Figure 11 1. Thermal-overload protector reset button 3. Power cord 2. ON/OFF switch g020669 Figure 12 Motor ON/OFF Switch 1. Motor ON/OFF switch The ON/OFF switch (Figure 12) 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 18). 1. Remove the pin from the pintle hitch and open it (Figure 19). Important: Apply thread-locking compound as needed in the future. A 1 2 B 3 5 4 C D G019807 Figure 18 1. Coupler handle 4. Bolt 2. Coupler 5. Hitch ball G019809 3. Clamp Figure 19 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 23). 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 Setting the Operating Voltage 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). A The machine can operate with a 115 V or 230 V supply voltage. The voltage block determines the operating voltage of the machine (). Use the following steps to change the operating voltage: B 1. Park the machine on level ground. 2.
Powering the Machine with a Portable Generator plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the machine plug or extension-cord plug in any way. When using a portable generator as an electrical source, ensure the following power output specifications: Note: The machine uses a twist-locking plug. Extension Cords Length Wire Gauge 15.2 m (50 ft) 10 AWG 22.8 m (75 ft) 10 AWG 30.
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.
5. Rotate the dump handle clockwise until the drum latch locks the drum in the upright position (Figure 28). 6. After discharging a batch of material, clean the drum; refer to Cleaning the Drum (page 21). Note: This step will clean the paddles and drum between batches and prevent dried material from forming, and contaminating the next batch of material. Cleaning the Drum Important: Do not strike on the drum with a shovel, hammer, or any other device to loosen any accumulated dried materials. 1.
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.
