SAFETY FIRST REMEMBER: The careful operator is the best operator. Most accidents are caused by human error. Certain precautions must be observed to prevent the possibility of injury or death. DO NOT ALLOW PERSONNEL OTHER THAN THE QUALIFIED OPERATOR NEAR THE MACHINE. NEVER START MACHINE UNTIL ALL GUARDS AND SAFETY SHIELDS ARE IN PLACE.

SAFETY READ BEFORE YOU FEED EQUIPMENT SAFETY GUIDELINES Safety of the operator is one of the main concerns in designing and developing a new piece of equipment. Designers and manufactures build in as many safety features as possible. However, every year many accidents occur which could have been avoided by a few seconds of thought and a more careful approach to handling equipment.
Page 10
SAFETY READ BEFORE YOU FEED KEEP ALL SHIELDS IN PLACE Do not operate mixer/feeder without safety shields in place. Rotating parts can crush or dismember causing personal injury or death. Disconnect PTO driveline before removing shields for adjustment or service. OPERATE MIXER/FEEDER SAFELY Rotating parts can entangle or strike people, resulting in personal injury or death.
Page 11
SAFETY READ BEFORE YOU FEED STAY CLEAR OF ROTATING DRIVELINES Entanglement in rotating driveline can cause serious injury or death. Keep tractor master shield and driveline shields in place at all times. Make sure rotating shields turn freely. Wear close fitting clothing. Stop the engine and be sure PTO driveline is stopped before making adjustments, connections, or cleaning out PTO driven equipment .

Replace safety decals and signs that are missing or have become illegible. Replaced parts that displayed a safety sign should also display the current sign. Safety decals or signs are available from your dealer or the ROTO-MIX manufacturing plant. How to Install Safety Decals: Be sure that the installation area is clean and dry.

Your best assurance against accidents is a careful and responsible operator. If there is any portion of this manual or function you do not understand, contact your dealer or the ROTO-MIX plant. BEFORE OPERATION: Carefully study and understand this manual.
Page 17
SAFETY READ BEFORE YOU FEED DURING OPERATION: Beware of bystanders, particularly children! Always look around to make sure that it is safe to start the engine of the towing vehicle or move the unit. This is particularly important with higher noise levels and quiet cabs, as you may not hear people shouting.
Page 18
SAFETY READ BEFORE YOU FEED DURING OPERATION (CONT.) Never leave running mixer/feeder unattended. As a precaution, always recheck the hardware on mixer/feeder following every 100 hours of operation. Correct all problems. Follow the maintenance safety procedures. FOLLOWING OPERATION: Following operation, or when unhitching, stop the tractor or towing vehicle, set the brakes, disengage the PTO and all power drives, shut off the engine and remove the ignition keys.
Page 19
SAFETY READ BEFORE YOU FEED HIGHWAY AND TRANSPORT OPERATIONS (CONT.): Comply with state and local laws governing highway safety and movement of farm machinery on public roads. Use approved accessory lighting flags and necessary warning devices to protect operators of other vehicles on the highway during daylight and nighttime transport.

Drain rain water out of mixer before use. 1” of rain in a 920-18 equals (101 gal) 843 lbs. of water which will increase the moisture in 1000 lbs. of dry hay (@ 12%) to 52% moisture or 500 lbs.
ADJUST TRAILER HITCH CLEVIS Mixer should be approximately level when attached to tractor. Adjust clevis by changing hole location on tongue. Hitch Pin Size — 1” x 7” LUBRICATION DISENGAGE PTO & SHUT OFF POWER BEFORE LUBRICATING THE MACHINE. LOOSE OR FLOPPY CLOTHING SHOULD NOT BE WORN BY THE OPERATOR.
