4.5. PTO shaft
Before operating, read bar manufacturer's manual placed on the bar. Follow all safety
precautions in that manual.
Use only PTO shafts recommended by tedder’s manufacturer with guards in good condition.
In order to operate safely, use only undamaged PTO shafts and shields. Damaged PTO shafts
and shields must be repaired or replaced with new ones before use.
4.6. Hydraulic assembly
Hydraulic assembly is under high pressure. Hydraulic oil under pressure may penetrate skin
and cause serious injury or death. Skin and eyes should be protected when working around this
assembly.
In case of injury caused by a liquid under pressure, call a doctor immediately.
Hydraulic hoses can be connected to the tractor's hydraulics provided that both the tractor’s and
the tedder's hydraulic assemblies are not under pressure. To remove the pressure from the
hoses, start the tractor's hydraulic valves several times with the tractor off.
When looking for oil leaks, do so safely. Use a cardboard card. Do not touch any potential
leaks until the entire hydraulic assembly has been relieved of pressure.
Use only hydraulic oil featuring oil purity class 9 - 10 in accordance with NAS 1638
.
When using hydraulic hoses:
Avoid stretching the hoses when operating.
Do not allow hydraulic hoses to get deflected.
Do not expose hydraulic hoses to contact with any sharp edges.
If damaged or worn, replace the hoses with new ones.
Useful life for hydraulic hoses is 5 years from their production date.
