Safety of the operator is one of the main concerns in designing and developing a new
piece of equipment. Designers and manufacturers 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. You, the
operator, can avoid many accidents by observing the following precautions in this section.
To avoid personal injury, study the following precautions and insist those working with
you, or for you, follow them.
In order to provide a better view, certain photographs or illustrations in this manual may
show an assembly with a safety shield removed. However, equipment should never be
operated in this condition. Keep all shields in place. If shield removal becomes necessary
for repairs, replace the shield prior to use.
Replace any CAUTION, WARNING, DANGER or instruction safety decal that is not readable
or is missing. Location of such decals is indicated in this booklet.
Do not attempt to operate this equipment under the inuence of drugs or alcohol.
Review the safety instructions with all users annually.
This equipment is dangerous to children and persons unfamiliar with its operation. The
operator should be a responsible adult familiar with farm machinery and trained in this
equipment’s operations. Do not allow persons to operate or assemble the unit until they
have read this manual and have developed an understanding of the safety precautions
and how it works.
To prevent injury or death, use a tractor with a Rollover Protective Structure (ROPS). Do
not paint over, remove or deface any safety signs or warning decals on your equipment.
Observe all safety signs and practice the instructions on them.
Never exceed the limits of a piece of machinery. If its ability to do a job, or to do so safely,
is in question - DON’T TRY IT.
