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.
the appropriate air pressure for the tires as installed at the factory. A Important: Always check the information on the actual tires for the correct air pressure requirement. Important: The most common cause of tire trouble is under-inflation. Maintain full air pressure. Tire Air Pressure Model Tire pressure 68012C Max 414 kPa (60 psi) 68018C, 68019C Max 241 kPa (35 psi) B 3. Ensure that the wheel lug nuts are torqued to 108 to 122 N-m (80 to 90 ft-lb).
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 3. Clamp G019809 Figure 19 2. Apply chassis grease to the socket of the coupler and the area of the clamp that contacts the ball. 2. Position the ring on the tow pole onto the hook of the pintle hitch (Figure 19). 3.
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. 2 G020828 Figure 22 1 Note: The machine uses a standard 4-flat plug. If your tow vehicle has a different type of plug, obtain an adapter from an automotive parts store. Important: Routinely check the lights to ensure that they are working properly, including the tail lights, brake lights, and each appropriate turn signal.
Towing the Machine WARNING Towing the machine at high speed increases the risk of a hitch malfunction and tire failure. Higher speeds also increase the momentum of the machine and braking distance. If the machine becomes detached from the tow vehicle at high speed, it could cause damage to property, or injury or death to bystanders. Do not exceed 88 km/h (55 mph) when towing the machine. For poor road conditions or inclement weather, reduce speed accordingly. Figure 23 WARNING 1.
4. Repeat step 3 at the opposite side of the machine (B of Figure 25). 5. Ensure that the drum latch is engaged and that the drum does not rotate toward the dump position. Opening and Closing the Cowl Opening the Cowl 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 (B of Figure 25). A B 1 2 1 C D 3 4 g020906 Figure 25 1.

Powering the Machine Important: Use only extension cords with terminals and sockets for the live, neutral, and ground wires. Setting the Operating Voltage Important: Connect the machine to only a receptacle with live, neutral, and ground connections. The machine can operate with a 115 V or 230 V supply voltage. The voltage block determines the operating voltage of the machine (Figure 11).
Stopping the Motor 2. Disconnect the electrical plug for the machine from the power source (Figure 26). WARNING In an emergency situation, stop the motor immediately. 1. Move the clutch lever to the OFF position; refer to Controlling the Paddles (page 19). 2. Switch the ON/OFF switch to the OFF position; refer to Motor ON/OFF Switch (page 11). 3. Unplug the power cord. 3 Controlling the Paddles DANGER This machine is capable of amputating hands.
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 27). 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 21), 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 5. Rotate the dump handle clockwise until the drum latch locks the drum in the upright position (Figure 29). DANGER 6. After discharging a batch of material, clean the drum; refer to Cleaning the Drum (page 21). Contact with the mixing paddles could cause damage or injury. Note: This step will clean the paddles and drum between batches and prevent dried material from forming, and contaminating the next batch of material. Never put your hands inside the drum at any time.
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.
