flow restrictive orifice. After you have repaired the hydraulic hose, the system
resets itself and is ready for operation.
There are various types of tractor hydraulic systems; the quick connect couplers
are supplied by the owners. Please consult your tractor manual for the proper
couplers.
Before you connect your hydraulic hoses, check that the quick connect couplers
on the auger and tractor are clean and free of any dirt or debris; wiping them
down with a cloth.
CAUTION:
Dirt in the hydraulic system can damage the cylinder o-rings. This may
cause leakage and possible system failure.
Do not disconnect the hydraulic coupler when the system is under pressure.
Relieve all pressure and then disconnect.

5.2 Cylinder Hydraulics

The testing done on Harvest International auger hydraulics was done using a
pressure gauge with 3000psi maximum rating. This was used simply as a
guide. The psi requirements for an individual auger may vary slightly.
Have approximately four liters of hydraulic fluid in your system. Check that the
valve on the hose to lift the cylinder is open. Start tractor and engage
hydraulics. Raise the auger to desired height, and close hose valve. You must
turn valve while the hydraulic system is pressurized; do not disconnect
hydraulic couplers.
