MAINTENANCE/SERVICE
FLOAT SPRING HARDWARE
To prevent premature wear, apply an anti-seize/
lubricating compound to header float spring
adjustment bolt threads (A) and washers (B) (four
of each) before adjusting header floatation.
HYDRAULIC SYSTEM
Hydraulic Hoses - Check daily for leakage.
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 pin-
holes and nozzles which eject fluids under
high pressure. Use a piece of cardboard or
paper to search for leaks. IF ANY fluid is
injected into the skin, it must be surgically
removed within a few hours by a doctor
familiar with this type of injury or gangrene
may result.
IMPORTANT:
• Ensure all hydraulic couplings are properly
mated and fully engaged before operating
header.
• To avoid wasting oil, do not direct more flow to
the header drive hydraulic circuit than can be
handled by the adapter flow control (maximum
18 GPM). See "Header Controls" in Operation
section.
• 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
Bi-Directional tractor, change oil in tractor
hydraulic system and in combine adapter
hydraulic reservoir to match combine system.
