more careful approach to handling equipment. You, the operator, can avoid accidents by

Keep all shields in place. If shield removal becomes necessary for repairs, replace 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 sprayer under the influence of alcohol or drugs.
Review safety instructions with all users.

Operator should be a responsible adult. DO NOT ALLOW PERSONS TO OPERATE OR

ASSEMBLE THIS SPRA YER UNTIL THEY HA VE DEVELOPED A THOROUGH UNDERSTANDING
OF SAFETY PRECAUTIONS AND HOW IT WORKS.

To prevent injury or death, use a tractor equipped with a roll over protective system (ROPS).
Do not paint over, remove, or deface any safety signs or warning decals on your sprayer.
Observe all safety signs and practice instructions on them.

SAFETY SIGN CARE

 Keep safety signs clean and legible at all times.
 Replace safety signs that are missing or have become illegible.
 Replaced parts that displayed a safety sign should also display the current sign.

 Be sure that the installation area is clean and dry.
 Decide on the exact position before you remove the backing paper.
 Remove the smallest portion of the split backing paper.

 Align the decal over the specified area and carefully press the small portion with the

exposed sticky backing in place.
