EQUIPMENT SAFETY GUIDELINES
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 you yourself,
follow them.
In order to provide a better view, certain 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 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 UNIT UNTIL THEY HAVE 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.
Never exceed 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.
LIGHTING AND MARKING
It is the responsibility of customer to know lighting and marking requirements of local high-
way authorities and to install and maintain sprayer to provide compliance with regulations.
Add extra lights when transporting at night or during periods of limited visibility.

•Use of flashing amber lights is acceptable in most localities. However, some localities prohibit
their use. Local laws should be checked for all highway lighting and marking requirements.
•When driving a utility vehicle and sprayer under 20 mph (40 kph) day or night, use flashing
amber warning lights and a slow moving vehicle (SMV) identification emblem.
•Plan your route to avoid heavy traffic.
•Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including
narrow bridges, intersections, etc.
•Be observant of bridge loading ratings. Do not cross bridges rated lower than gross weight at

•SAFETY CHAINS: If equipment is going to be transported on a public highway, always
follow state and local regulations regarding safety chains and auxiliary lighting. Be sure to
check with local law enforcement agencies for your own particular regulations. If required
safety chains should be obtained and installed. Only safety chains (not elastic or nylon/
plastic tow straps) should be used to retain connection between towing and towed ma-
chines in event of separation of primary attaching system. Use a high strength, appropri-
ately sized hitch pin with a mechanical retainer and attach safety chains. Criss cross
chains under tongue and secure to draw bar cage, mounting loops, or bumper frame.
