Models: STS60-23BV

WARNING
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT
IN SERIOUS INJURY OR DEATH.
• Read this manual completely as well as other manuals that came with your sprayer/
spreader.
• DO NOT operate on steep slopes. To check a slope, attempt to back up it. If the
machine can back up the slope without the wheels slipping, reduce speed and use
extreme caution.
• Under no circumstances should the machine be operated on slopes greater than 15
degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.
• Weight in the storage tanks and hopper will transfer when on a slope, this may
cause a loss of traction or increased risk of a roll-over.
• When operating with a heavy load, reduce speed and allow sufficient braking
distance. Use extra caution on slopes.
• Liquid loads shift during operation, especially while turning, going up or down
slopes, sudden changes in speed or while driving over rough surfaces. Shifting
loads can cause the machine to tip over.
• Stay two machine widths away from slopes, drop offs, ditches, water,retaining walls,
avoid any slope exceeding 15 degrees.
• DO NOT operate on wet grass. Wet grass reduces traction and steering control.
• Keep all shields in place.
• Before performing any maintenance or service, stop the machine, remove the spark
plug wire(s), and remove the ignition key.
• If a mechanism becomes clogged, stop the engine before cleaning.
• Keep hands, feet, and clothing away from power-driven parts.
• Keep others off the machine (only one person at a time).
REMEMBER - YOUR SPRAYER/SPREADER IS ONLY AS SAFE AS THE
OPERATOR!
HAZARD CONTROL AND ACCIDENT PREVENTION ARE DEPENDENT UPON THE AWARENESS,
CONCERN, PRUDENCE, AND PROPER TRAINING OF THE PERSONNEL INVOLVED IN THE
OPERATION, TRANSPORT, MAINTENANCE, AND STORAGE OF THE EQUIPMENT.
This manual covers the operating instructions and illustrated parts list for:
STS60-23BV with a serial number of V9800001 to V9899999
