5.11.5 Header and Reel Hydraulics
Refer to this section for information on the hydraulic components which affect the operating characteristics of the header
and the reel (if the header is equipped with a reel).
Hoses and Lines
Check hydraulic hoses and lines daily for signs of leaks.
Figure 5.192: Hydraulic Pressure Hazard
WARNING
• Avoid high pressure fluids. Escaping fluid can penetrate the
skin, causing serious injury.
• Relieve the pressure in the hydraulic system before
disconnecting any hydraulic fittings. Tighten all connections
before applying pressure.
• Keep away from pin-holes and nozzles which can eject high-
pressure fluids.
Figure 5.193: Checking Hydraulic Leaks
WARNING
• Use a piece of cardboard or paper to search
for hydraulic leaks. Do NOT use your hand or any other part
of your body.
• If ANY hydraulic fluid is injected into the skin, it must be
surgically removed within a few hours by a doctor familiar
with this type of injury. Otherwise, this injury becoming
infected with gangrene.
IMPORTANT:
Contaminants such as dirt, dust, and water are the major cause of damage to the hydraulic system.
• If the hydraulic system’s components must be disconnected for service, protect the ends of hoses, tubing, and ports
from contamination. Cover openings with clean, lint-free towels, or clean plastic bags.
• Before installing a replacement hydraulic hose, flush the inside of those with clean diesel fuel or commercial petroleum
cleaning solvent for a minimum of ten seconds. Do NOT use water, water soluble cleaners, or compressed air to clean a
hydraulic hose.
• The hydraulic system’s components are manufactured with a great degree of precision, and have been assembled in
sanitary conditions at the factory. Do NOT attempt to service these components in the field, except to maintain the
proper oil level, change the hydraulic oil and filters, and to adjust the relief pressures as described in this manual.
