8.7.5 Hydraulic Adjustments
Note: When adjusting valves, first loosen the jam nut around the stem, then use a hex allen wrench
to turn the stem clockwise to increase pressure, or counterclockwise to decrease pressure.
Pressure Settings:
1. Main System Relief Pressure — 2,000 psi.
2. Knife Down Sequence Pressure — 1,200 psi.
3. Clamp/Knife up Sequence Pressure — Visual.
4. Clamp Pressure Reducer — 400-900 psi.
Adjustment Procedure:
Note: On all valves, turning in (clockwise) increases pressure; out (counter-clockwise)
decreases pressure.
1. Remove the lower front cover panel.
2. MAIN SYSTEM RELIEF PRESSURE: Use the Knife Down command in Maintenance Mode
to send the knife and clamp down. Read the pressure on the Main System gauge when the
knife is bottomed on the table. Adjust the main system relief valve (Figure 36, pg. 55) to
obtain a reading of 2,000 psi. It may be necessary to send the knife down several times.
