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 Failure to maintain correct tire pressure may result in tire failure and loss of control, resulting in property damage and serious injury or death.
2. Hitching a Machine with a Stamped Ball Coupler Ensure that the tires are inflated to the correct air pressure. The following Tire Air Pressure table shows the appropriate air pressure for the tires as installed at the factory. 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. 2. Open the coupler latch (Figure 17).
7. If the machine is equipped with a trailer-light kit, connect the wire plug of the tow vehicle to the wire plug of the machine. 6. Hitching a Machine with a Forged Ball Coupler 1. If the machine is equipped with a trailer-light kit, connect the wire plug of the tow vehicle to the wire plug of the machine. Hitching a Machine with a Pintle Hitch Tow Pole Apply removable thread-locking compound to the threads of the coupler bolt to prevent the coupler handle from coming loose (Figure 18). 1.
Connecting the Safety Chains to the Tow Vehicle Connect the safety chain to the machine and the tow vehicle as follows: 1. Pull the safety chain through the slots in the keyholes located in the front post of the machine, so that there is just enough slack on each side for turning around corners when towing the machine (Figure 20). 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. 2.
Adjusting the Axle Width 5. WARNING Mechanical or hydraulic jacks may fail to support the machine and cause serious injury. Use jack stands when supporting the machine. 1. 6. 7. Align a jack with an adequate lift height and weight capacity under the axle; refer to Specifications (page 11). 8. 2. Lift the machine until the tires are off the ground. 3. Use a jack stand at each support point on the rear frame extension (Figure 22).
Opening and Closing the Cowl gloves without draw strings or loose cuffs, eye protection, and a dust mask or respirator. A mesh visor alone does not provide sufficient eye protection; supplement with protective glasses. • Ensure that you are familiar with the safety Opening the Cowl regulations and shutdown procedures described in the Operator’s Manual. 1. • Ensure that all guards are in place and in good condition.
2. At the back of the machine, grasp the latch and pull it onto the latch anchor on the rear cowl. 3. At the side of the machine, grasp the latch and pull it onto the latch anchor on the rear cowl. 4. Repeat step 3 at the opposite side of the machine (Figure 24). To reduce the risk of electric shock, this machine has a polarized plug (unique blade shapes and widths).
Powering the Machine with a Portable Generator Important: Ensure that the paddles spin freely. Check for stone, masonry, or concrete material between the paddles and the drum. When using a portable generator as an electrical source, ensure the following power output specifications: 4. On the side of the junction box for the motor, press the reset button for the thermal-overload protector (Figure 25). Model Voltage Amperes Kilowatt hour Frequency/ phase 5.
Using the Clutch Lever Important: Ensure that the paddles do not turn when the clutch lever is in the OFF position. Move the clutch lever clockwise to engage the clutch, and counterclockwise to disengage the clutch (Figure 26). Use the clutch lever to control the power transmission to the paddles of the machine. g019873 Figure 26 1. OFF position 2. ON position Mixing the Material DANGER Eye and skin contact with concrete materials and breathing the dust involved is hazardous to your health.
Mixing a Batch of Material in the Machine 1. 7. Ensure that there is no old, loose material in the drum that can contaminate the batch of material; refer to Cleaning the Drum (page 23) and Dumping the Drum (page 22), then return the drum to the upright position. Using the Drum DANGER Contact with the mixing paddles could cause damage or injury. Note: Ensure that the drum is in the mix 2. 3. 4. 5. Release the drum latch and dump the drum; refer to Dumping the Drum (page 22).
3. Lift the handle of the drum latch (Figure 28). 4. With both hands on the dump handle, rotate it counterclockwise to discharge the contents of the drum (Figure 28). 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 28). 6. After discharging a batch of material, clean the drum; refer to Cleaning the Drum (page 23).
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.
Lubricating the Motor Bearings Service Interval: Every 6,000 hours Grease type: electric-motor bearing grease 1. Clean around each grease fitting with a rag. 2. Pump 1 or 2 shots of grease into each fitting (Figure 32). Important: Do not over-lubricate the motor. g021588 Figure 32 3. g021101 Figure 31 1. Pillow-block bearings 3. Front trunnion 2. Rear trunnion 2. Pump grease into each fitting as follows: • For the pillow-block bearings, pump 1 shot of grease into each fitting (Figure 31).
Lubricating the Drive Chain Belt Maintenance Service Interval: Every 40 hours—Lubricate the drive chain with a non-sticky chain lubricant. Servicing the Belts Apply a chain lubricant that is non-sticky to help prevent dirt and abrasive particles from sticking to the chain. Inspecting the Belts 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.
