Safety • Read and understand the contents of this Operator’s Manual before you start the engine. Ensure that everyone using this product knows how to use it and understands the warnings. Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety-alert symbol (Figure 2), which means: Caution, Warning, or Danger—personal safety instruction.
• Do not carry any material in the machine when • • • • • • • – Ensure that the lug nuts are tight and torqued properly. – Ensure that the machine is properly secured. towing. Avoid sudden stops and starts. This can cause skidding or jackknifing. Smooth, gradual starts and stops improves towing. Avoid sharp turns to prevent rolling. Tow only with a vehicle that has a hitch designed for towing. Do not attach towed equipment except at the hitch point. Do not tow the machine faster than 88 km/h (55 mph).
• Ensure that all the guards and shields are securely in place before operating the machine. • If the mixing paddles strike an object or if the machine starts making an unusual noise or vibration, shut off the engine, wait for all moving parts to stop, and empty the drum. Inspect for clogging or damage. Clean, repair, and/or replace any damaged parts. • Do not change the engine governor setting or overspeed the engine. • Do not operate the machine when there is the risk of lightning.

Controls Dump Handle Become familiar with all the controls before you start the engine 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 Use the clutch lever to engage and disengage the paddles. g232185 Figure 9 g019875 1. Dump handle Figure 7 1. Clutch lever Drum Latch Use the drum latch to secure the drum to the mix position (upright) for mixing operations and when transporting the machine.
Engine Controls Fuel Valve The fuel valve (Figure 12 and Figure 13) is located underneath the choke lever. Move the lever for the fuel valve to the ON position before attempting to start the engine. When you have finished mixing, shut off the engine and move the fuel-valve lever to the OFF position. g019744 Figure 10 Model 60221HD shown 1. Recoil-start handle 5. Fuel cap 2. Fuel valve 6. Oil dipstick 3. Choke lever 7. Oil-drain plug 4. Throttle lever 8.
the engine is running, move the choke lever to the OPEN position. Do not use the choke if the engine is already warmed up or if the air temperature is high. Throttle Lever The throttle lever (Figure 12 and Figure 11) controls the speed (rpm) of the engine. It is located next to the choke lever. It sets the engine speed and therefore can increase and decrease the rotation speed of the mixing paddles. For best performance, set this control to the FAST position when mixing material.

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. Do not tow the machine with material in the drum. • Review and understand the Safe Operating Practices (page 5). • Test the brakes of the tow vehicle before towing.
g035115 Figure 18 Note: Use a wrench to keep the bolt from spinning. Hitching a Pintle-Hitch Coupler g035113 Figure 17 Hitching a Forged-Ball Coupler 1. Apply removable thread-locking compound to the threads of the coupler bolt to prevent the coupler handle from coming loose. Important: Apply thread-locking compound as needed in the future. 2. Apply chassis grease to the socket of the coupler and the area of the clamp that contacts the ball. 3. Hitch the machine as shown in Figure 18.
Connecting the Safety Chains to the Tow Vehicle 1. Pull the safety chain through the slots in the keyholes, so that the lengths on each side are equal. 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. g019927 Figure 21 1. Connecting link 3. Chain link 2. Safety chain mounting point on tow vehicle 4.
The corresponding turn-signal lights of the machine should illuminate. Adjusting the Axle Width Models with Adjustable Axles Only If your model is equipped with an adjustable axle (Figure 24), you can adjust the axle to the narrow position to move the machine through a narrow access point, such as the gate of a fence or the doorway of a building. WARNING The machine is not stable when towed with the axle in the narrow position. g029390 Figure 23 Tow the machine with the axle in the wide position. 1.
2. Ensure that all guards and paddles are in place and in good condition. 3. Perform all daily maintenance procedures prescribed in Maintenance (page 28). 4. Chock the front and back of the tires to prevent the machine from moving. 5. Move the drum to the upright position and lock it. Closing the Cowl Opening the Cowl g035135 Figure 26 Adding Fuel DANGER In certain conditions, fuel is extremely flammable and highly explosive.
• Do not store fuel either in the fuel tank or in fuel DANGER containers over the winter unless you use a fuel stabilizer. In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property. • Always place fuel containers on the ground away from your vehicle before filling.
Important: This space in the tank allows fuel to expand. Do not fill the fuel tank completely full. g019815 Figure 29 1. Choke lever 2. Fuel valve 3. g020679 Figure 28 Model 60221HD engine shown 3. Throttle lever Move the choke lever to the ON position (Figure 29). Note: A warm or hot engine may not require choking. 1. Maximum fuel level 4. Move the throttle lever 1/3 of the way toward the MAX position. 4.
DANGER This machine is capable of amputating hands. • Stay in the operator’s position while the machine is running. • Keep all bystanders a safe distance away from the machine. • Stop the machine immediately if any people or animals enter the work area. • Never place any part of your body into a position that causes an unsafe operating condition. g019747 Figure 31 Model 60221HD shown Important: Do not add more material than the batch capacity of the machine; refer to Specifications (page 17). 7.
7. Allow the paddles to mix the material until the ingredients have a uniform appearance. Note: If needed, add water or plaster, cement, or other binding material until the consistency of the batch is correct. Dumping the Material DANGER Contact with the mixing paddles could cause damage or injury. Never put your hands inside the drum while the engine is running.
4. With both hands on the dump handle, rotate it counterclockwise to discharge the contents of the drum (Figure 34). 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 34). 6. After dumping a batch of material, clean the drum to prevent dried material from contaminating the next batch of material; refer to Cleaning the Drum (page 27).
Maintenance WARNING Failure to properly maintain the machine could result in premature failure of machine systems causing possible harm to you or bystanders. Keep the machine well maintained and in good working order as indicated in these instructions. Important: Refer to your engine operator's manual for additional maintenance procedures.
