5. OPERATION
5.1.
Purging the Hydraulic System
5.1.1. Prior to first use, any air in the hydraulic system should be purged.
5.1.2. Before purging, ensure that the reservoir (fig.11) is topped up with hydraulic fluid.
5.1.3. Each pump will need to be purged separately. To do this:
Press the release pedal and operate the low speed pump for about 10 strokes.
5.1.4. Allow the release pedal to rise and operate again for 10 strokes; the ram should descend.
5.1.5. Pressing the release pedal should allow the ram to retract.
5.1.6. Repeat for the high speed pump and the air pump (keep the air pump pedal depressed
for about 10 strokes).
5.1.7. If the ram fails to move smoothly, repeat the process.
5.1.8. Check the oil level again and top up if necessary.
5.2.
Using the Press
5.2.1. Raise or lower the table to the required height. The table is counterbalanced
by gas struts to enable easy movement.
5.2.2. Insert the support pins beneath the table at the required height.
5.2.2. The ram can be moved laterally by applying firm force. This allows pressing
off-centre.
5.2.3. Insert the required saddle or press pin into the ram head (fig.12) and secure
with the grub screw.
5.2.4. Locate the arbor plates in the correct position to support the workpiece and
secure the workpiece to the arbors.
WARNING: the arbor plates supplied with PPF501 are rated at 30tonnes. When
pressing more than 30tonnes, therefore, the workpiece needs to be spread across
two arbor plates.
5.2.5. Use either the high speed manual pump or the air/hydraulic pump to lower the
ram to the workpiece. For final pressing, the low speed manual pump will give
finer control and feel.
5.2.6. Press the release pedal to retract the ram.
5.2.7. When not in use, ensure that the ram is retracted fully and that the air supply is disconnected.
6. MAINTENANCE
Note: Maintenance and repair must only be carried out by qualified person. Contact your Sealey stockist for details.
6.1
Always keep the press clean, dry and lubricate all moving parts at regular intervals.
6.2.
If the performance of the press deteriorates, purge the hydraulic circuit as in section 5.1.
6.2.
Should you need to check or replace oil ensure piston is fully retracted. Remove the oil reservoir filler plug (fig.11) and top up using Sealey
hydraulic jack oil. DO NOT use brake fluid. Contact your local Sealey dealer for details. After filling purge the system to remove any air.
