Final Assembly
•
Connect the Steel Pipe to the Pump and Valve Set and tighten using a 20 mm spanner.
•
Connect the solenoid wire to its terminal block using a 3 mm flat screwdriver. Place the block in position on the solenoid and
secure with the screws provided.
•
Ensure that the Oil Drain Plug has been replaced and tightened using a 13 mm spanner.
•
Fill to the maximum level indicated on the Oil Level Indicator
5
with the grade of hydraulic oil stipulated in the Technical
Specifications on page 5.
Pressure Setting
•
Connect the Pressure Setting Gauge Set and Hoses to the HydraPac.
•
Plug in the Setting Trigger (see illustration below).
•
Place the Tank Cover Assembly loosely in position. This is to prevent
excessive oil splash during setting.
•
Connect to the HydraPac Power Supply and switch on.
•
Turn the isolator on the electric enclosure to 'On' .
•
Ensure that both Valves on the Pressure Setting Gauge Set are fully
open.
•
Depress and release the Trigger a few times allowing the oil to circulate
freely. This will remove all the air from the hydraulic system and also
indicate if the Directional Valve is functioning.
•
Keeping the Trigger Switch depressed, slowly close the Valve 'A'.
reading the pressure on the gauge take note of the pressure when the
release valve opens. Adjust the screw on the left hand side Spring
Dome, (the lower of the two domes) to obtain the setting given on the
Gauge Set illustration. Once the correct pressure setting has been
achieved, lock the adjusting screw in place with the nut provided using a
10 mm spanner.
•
To set the Return Pressure repeat as in previous step but with the
Trigger Switch released. Valve 'A' must be fully open and Valve 'B'
utilised to obtain the setting. Adjustments for the pressure are to be made on the second Spring Dome.
•
On completion of the pressure settings, replace and secure the tank cover with the 10 mm socket head cap screw using a 5 mm
allen Key and reset the timer if need be.
Note: It may be necessary during Pressure Setting to temporarily increase the delay time on the "Sleep Mode" Timer.
