4. Shift the valve and build pressure in the system.
Using an Allen wrench, turn the set screw
counter-clockwise to decrease pressure and
clockwise to increase pressure.
NOTE: To get an accurate setting, decrease the
pressure to a point below the fi nal setting and
then slowly increase the pressure until it reaches
the fi nal setting.
5. Tighten the locking nut when the desired
pressure is set.
6. Shift the valve to the neutral position, allowing
the system pressure to return to 0 psi.
7. Recheck the fi nal pressure setting by shifting
the valve and pressurizing the system.

6.0 TROUBLESHOOTING

1. If the system will not build pressure, check
relief valves in pump for proper setting (refer to
pump repair sheet). Check and secure all hose
connections. If trouble is not corrected by this
action, remove cylinder and hoses from valve.
Now place a 10,000 PSI gauge directly in valve
port "A" and place the valve in ADV position. If

pressure cannot be developed, the unit should
be taken to the nearest ENERPAC authorized
service center. If pressure develops, the problem
is located in the cylinder, hoses, or couplers.

detailed "troubleshooting" suggestions.

7.0 MAINTENANCE

1. Periodically check all hydraulic connections
to be sure they are tight. Loose or leaking
connections may cause erratic and/or total
loss of operation. Replace or repair all defective
parts promptly.
2. Periodically check the hydraulic oil level in your
system. Refer to the oil fi lling instructions for
complete data.
3. Change hydraulic oil approximately every 250-
300 hours of operation. In dusty or dirty areas,
it may be necessary to change the oil more
frequently.
