Booster Pump Adjustment
If the discharge pressure from the booster pump stays below 90 psi (6 bar) while the intensifier is
shifting, the relief valve on the booster pump should be adjusted.

1. Turn the cutting water supply on.
2. Start the machine and initiate normal, shifting operation.
3. Observe the discharge pressure from the booster pump. If the pressure stays below 90 psi
(6 bar), continue with Step 4.
4. Stop the intensifier and remove the acorn nut on the side of the pump to access the
adjustment screw. It is normal for water to leak out when the acorn nut is removed.
5. Use a flat screwdriver and turn the adjustment screw clockwise to increase the discharge
pressure or counter-clockwise to decrease the pressure. Adjust the pressure to the highest
desired pressure, within normal booster pump range.
