SAFE OPERATION 2  
SAFETY  
Failure to heed these warnings may result in personal injury or death.  
Before operating this machinery read the owner’s manual carefully.  
Use OSHA approved eye, ear  
and head protection to protect  
the operator from any flying  
debris and noise.  
All personnel except operator should be 150 feet clear of machinery before starting  
or operating it.  
Never use drugs or alcohol before or while  
operating your brush mower.  
Be aware that operating equipment for an extended period of time can result in fa-  
tigue or boredom and may cause the operator to lose awareness of what he/she is  
doing. It is recommended that scheduled work breaks be taken to avoid this.  
Keep hands and loose clothing away from any power-driven parts.  
Avoid contact with hot surfaces including pumps, motors, hydraulic oil tanks and  
hose connections.  
Do not operate this machine without all guards being in good condition and firmly in  
place.  
Do not operate this machine on a excavator that is not properly maintained. If a  
control failure should occur while operating this machine, immediately shut it down  
and perform repairs before continuing.  
Be aware of the cutter drum rotation direction and do not let bystanders stand  
within 150 feet to either side of the mower.  
Under no circumstances should the blades of this attachment contact the ground or  
be curled up to where they are visible to the operator. Serious injury or death can  
occur.  
Always walk the area to be worked to insure the jobsite is free of obstacles and de-  
bris that could injure the operator or damage the machine.

SAFETY (cont.)  
SAFE OPERATION 3  
Stop the operation of this machine when people or vehicle driver’s vision becomes  
obscured, caused by the discharge of materials and dust. Also avoid operating this  
attachment in unusually foggy or dusty conditions or at night.  
Never leave the excavator or the brush shredding attachment unattended while it is  
in the lifted position or while the shredder is spinning.  
Keep away from rotating elements to prevent entanglement.  
Listen for blades to completely stop prior to dismounting  
machine.  
Use flashing warning lights when operating on highways,  
except when prohibited by law.  
If using the side shredding method, drive at a speed you  
can safely operate the vehicle and attachment. Normal  
ground speed ranges from 0-5 miles per hour. Use slow  
speeds when operating on or near slopes, ditches, drop-  
offs, or when debris and foreign objects are to be avoided.  
Use the following guidelines to reduce the risk of equipment  
and grass fires:  
- Do not smoke or have an open flame near the machinery.  
- Do not drive into burning areas or areas that have been freshly burned.  
- Do not mow areas that are tinder dry and can burn easily.  
- DO NOT allow debris to collect near hydraulic motors and gearboxes.  
Do not position the attachment or turn it so sharp that the hoses could get pinched  
or squeezed.

Maintain all safety decals and make sure they are visible to the operator and by-  
standers. If decals are worn, contact your nearest Kubota dealer for replacements.  
Replace bent or broken blades with new ones. Do not attempt to weld or bend  
damaged blades. This can cause cracking or other types of damage that could re-  
sult in the blade being thrown from the brush mower.  
Wear gloves and eye protection and exercise care when handling blades. Also be  
alert to worn or damaged surfaces that could have sharp edges.  
Disengage hydraulics and shut off engine, bleed off hydraulic pressure to both high  
and low flow circuits allowing all movement to stop before leaving the operator’s po-  
sition to adjust, lubricate, clean, unclog, remove or install the attachment. See Ku-  
bota KX080-3 Operators Manual for detailed instructions on bleeding off hydraulic  
pressures.  
Before working on or underneath the attachment, place blocks on both sides (front  
and back) of operating vehicle tires or treads and under each end of the attachment  
to prevent accidental lowering of the machine. Also remove the ignition key from  
the operating vehicle and allow all movement to stop before beginning work.
