OPERATION
HYDRAULIC TRIPPING SYSTEM - SETTING PRESSURE
• The tripping force can be adjusted by adjusting system pressure on the hydraulic block.
• Pressure can be adjusted from 500 to 2500psi.
• To increase system pressure (more resistance to tripping) turn the adjustment screw on the
hydraulic block clockwise.
• To decrease system pressure (less resistance to tripping) turn the adjustment screw on the hydraulic
block counter-clockwise.
• Typically, it is best to set the system to the lowest pressure that keeps the knives in the ground but
allows the units to trip when encountering an obstruction. Lower pressures will prolong the life of
the system and reduce knife breakage.
• When setting your hydraulic tripping system start between 500 and 1000 psi and work up to find
the best pressure for your conditions.
Refer to the chart below for recommended pressure
adjustment increments as you get started
• Make fine adjustments as you start to find a pressure range that keeps the knives engaged in
obstruction-free soil.
