Pressure Adjusting; Air Purge - Baileigh Industrial HSP-30M Operator's Manual

Pressure Adjusting

1. Start the hydraulic unit.
2. Make sure the piston is in rest position (no force applied).
3. Set the table height in the top position.
4. Place the heal blocks on the table.
5. Loosen the lock nut behind the hand knob and turn the knob counter clockwise 1/2 to 1 full
turn to reduce the pressure. Do not overturn and remove the knob!
6. Extend the ram down until it reaches the heal blocks. Hold the lever in the down position and
read the pressure on the pressure gauge.
7. Slowly turn the knob of the regulator in or out as desired to set the desired pressure. NEVER
EXCEED THE MAXIMUM PRESSURE SETTING!
8. When the pressure is set, hold the knob in position and lightly tighten the lock nut to hold the
knob and prevent inadvertent pressure changes.

Air Purge

When starting up for the first time or when maintenance on the hydraulic system has been
performed, the hydraulic system needs to be purged.
1. Make sure there is no work piece on the table.
2. Start the hydraulic unit.
3. If not already fully retracted, using the directional control valve to fully retract the ram.
4. Extend the ram to the fully lowered position.
5. Now fully retract the ram.
6. Repeat this complete cycle at least 6 times to be sure all air is out of the system.
IMPORTANT: Air in the hydraulic system can cause unexpected piston movement
and poor overall press operation.
