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 your owners 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.
Do not attempt to operate this equipment under the influence of alcohol or drugs.
Review safety instructions with all users annually.
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 equipment. 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 highway authorities and
to install and maintain equipment to provide compliance with regulations. Add extra lights when transporting at
night or during periods of limited visibility.
Lighting kits are available from your dealer or from manufacturer.
REMEMBER
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 local authorized dealer or manufacturer.

HIGHWAY AND TRANSPORT OPERATIONS
•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 agen-
cies for your own particular regulations. Only safety chains (not elastic or nylon/plastic tow straps) should be
used to retain connection between towing and towed machines in event of separation of primary attaching
system. Use a high strength, appropriately 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.
• Adoptsafedrivingpractices:
- Keep brake pedals latched together at all times. NEVER USE INDEPENDENT BRAKING WITH
MACHINE IN TOW, LOSS OF CONTROL AND/OR UPSET OF UNIT CAN RESULT.
- Always drive at a safe speed relative to local conditions, ensure that your speed is low enough for an
emergency stop. Keep speed to a minimum.
SAFETY

Page 8 AG20003
- Reduce speed prior to turns to avoid risk of overturning.
- Always keep tractor or towing vehicle in gear to provide engine braking when going downhill. Do not coast.
