MAINTENANCE/SERVICE
HYDRAULIC SYSTEM
Hydraulic Hoses and Lines
Check hydraulic hoses and lines daily for signs of
leaks.
WARNING: Avoid high-pressure
fluids. Escaping fluid can penetrate
the skin causing serious injury.
Relieve pressure before disconnecting
hydraulic lines. Tighten all connections before
applying pressure. Keep hands and body away
from pinholes and nozzles that eject fluids
under high pressure. Use a piece of cardboard
or paper to search for leaks. IF ANY fluid is
injected into the skin, a doctor familiar with
this type of injury must surgically remove it
within a few hours or gangrene may result.
IMPORTANT:
• Ensure all hydraulic couplings are fully
engaged before operating header.
• Keep hydraulic coupler tips and connectors
clean. Dust, dirt, water and foreign material
are the major causes of hydraulic system
damage.
• To prevent improper mixing of oils:
If header is to be switched back and forth from
combine to windrower, change oil in
windrower tractor (or Bi-Directional Tractor)
hydraulic system to match combine hydraulic
system.
