re servicing the disk, always:
1. Lower the disk to the ground.
2. Shut the tractor engine off.
3. Engage the tractors parking brake and/or place transmission in park.
4. Relieve the hydraulics by moving the control lever back and forth.
5. Remove the ignition key.
□ Never work under a raised disk. The disk could fall suddenly causing serious personal injury.
Never rely on the hydraulic system to hold the disk up.
□ Periodically visually inspect the entire disk. Hydraulic fluid leaks and broken, missing or faulty
parts can create a hazard. Make necessary repairs.
□ Use caution when inflating tires. Use a clip-on air chuck, extension hose with gauge, and stand to
one side away from the tire when inflating to avoid the possibility of personal injury due to blow-
offs, etc. Maintain proper air pressure in the tires. Never exceed the manufacturer’s maximum
p.s.i. displayed on the sidewall of the tire.
□ Before disconnecting any hydraulic line relieve the pressure. Escaping hydraulic oil under
pressure can have sufficient force to penetrate the skin causing serious personal injury. If injured
by escaping hydraulic fluid, obtain medical treatment immediately.
□ Handle the gang assemblies with care. The disk blades are sharp and can cut or slice skin. Use
chock blocks to prevent the gang assemblies from rolling during servicing. Wear gloves when
handling the disk blades or gang assemblies.
□ After working on the hydraulic cylinder or any other components of the hydraulic system, carefully
cycle the hydraulic cylinder several times to purge air from the system and check all components
for leaks. Always be sure the hydraulic lines are free of air and do not leak. ORB fittings may not
leak even though they are only finger tight – tighten with a wrench. Check hydraulic hoses for
cuts or abrasions and replace if necessary.
□ Securely support any machine elements that must be raised for service work. Use suitable lifting
devices and support stands where required. If using chains or straps make sure they are of
sufficient strength for the load and are in good repair.
□ To avoid injury wear gloves, steel-toe boots, safety glasses, hearing protection, safety helmet and
other safety equipment where warranted.
□ Understand the service procedure before doing the required work. Keep the work area clean and
dry.
