MAINTENANCE SAFETY
1. Do not loosen or disassemble hydraulic components when there is pressure within those components. Hydraulic components under
pressure may cause parts and hydraulic fluid to fly out at a high velocity, which could cause serious injury. Always relieve the
pressure in the hydraulic system before making adjustments to the hydraulic system. If injured by escaping hydraulic fluid, see a
medical doctor immediately.
2. Check all hydraulic hoses periodically for signs of ruptures and leaks. Always use wood or cardboard as a backstop, and wear gloves
and eye protection when searching the hydraulic system for leaks. Spurting hydraulic fluid can cause injury if it penetrates the skin
or the eyes. If injured by escaping hydraulic fluid, see a medical doctor immediately.
3. Always relieve the pressure in the hydraulic system when the disc is not being operated.
4. Always permit parts which contain hot fluid to cool to a safe temperature before handling or disconnecting these parts.
5. Always wear safety glasses or goggles and gloves when working on the hydraulic system.
6. To fill wing lift cylinder with hydraulic oil, extend and contract cylinder within slot on wing until cylinders are completely filled with
oil. Do not fold wing until cylinder is completely filled, wing(s) will free fall if cylinders are not filled with oil, causing serious damage
to machine or serious injury or death to person(s) nearby.
7. Lower the disc to the ground when servicing or making adjustments. If the disc must be serviced in the raised position, place blocks
under frame. Do not rely on hydraulics lock up valves as a safety device. If the hydraulic system failed, or if the hydraulic lever was
accidentally operated, the disc could drop.
8. Do not lubricate disc while it is in motion. You may fall in front of disc and be seriously or fatally injured.
9. Always place all tractor controls in neutral and lock
brakes when hitching disc to tractor. Tractor could roll
backwards when hitching disc.
10. If wing lift cylinder is removed when wing is folded into transport position, always install a safety chain between wing frame and main
frame to prevent wing(s) from falling. If wing(s) fell, serious injury or death could occur to person(s) nearby and machine would be
damaged severely.
TRANSPORT SAFETY
1. When trailing the disc over public roads, use the SMV emblem and warning light for protection of tractor and other motor vehicle
operators. Check local laws for width and height maximums.
2. When transporting disc always place both hydraulic lock up valves in “closed” position. See Section 7 of Operating Instructions on
page 6. If hydraulic lever was accidentally operated the disc could drop or wing could fall.
3. Do not exceed 10 mph (16 km/h) when transporting the disc on smooth surfaces. Reduce speed when transporting on rough surfaces.
Excessive speed could cause loss of tractor control and damage to disc and tractor. Do not transport the disc with any other vehicle
except a tractor.
4. When transporting the disc with the wing(s) folded (UP), be sure there is sufficient clearance under all power lines and other
overhead obstructions. Serious injury or death can result from contact with electrical lines. Use care to avoid contact with electrical
lines when moving or operating the disc.
5. Always attach a safety chain to the tractor drawbar and
the disc hitch before transporting the disc. Serious
damage and injury could result from the disc separating
from the tractor drawbar.
