3.7.
Install the hook pins (8) onto the support plate (7) using the M8 nuts (11) and M8 washers (10).
3.8.
Affix the springs (5) to the bars on the upper support (1) and to the hook pins (8) on the support plate (7). Adjust the length of the
hook pins (8) using the M8 nuts (11) so that the support plate (7) is parallel to the upper support (1).
3.9.
Attach the hydraulic unit (6) to the support plate (7) using the M8x12 bolts (20). Ensure that the saddle of the hydraulic unit locates
securely into the aperture on the upper support (1).
3.10.
Place the v-blocks (12) onto the table (13).
4. INSTALLATION & OPERATING
4.1.
INSTALLATION.
4.1.1. Securely attach the press to a flat, firm, level surface taking into account clearance for workpieces.
4.1.2. Before operating the press, purge the hydraulic system of the hydraulic unit (6), in order to eliminate any air that may have
accumulated during transit. Fit handle (21) over the release valve and turn anti-clockwise to open valve (fig.1). Insert handle into
handle sleeve and pump several times to ensure full internal lubrication and to bleed air from the system. Fit handle back over the release
valve and turn clockwise to close (fig.1).
 DANGER! This model is purpose designed to withstand greater loads than the hydraulic units can develop. For safety reasons, always
ensure the workpiece and press tools are secured on the table and will not flex or suddenly "give way" causing danger to operator or the
component. Also ensure you have read and understood chapter 1 safety instructions.
4.2.
OPERATING INSTRUCTIONS.
4.2.1. Position the table at the required operating height by inserting the support pins into the appropriate holes in the uprights.
4.2.2. Place the V-blocks onto the table, then place workpiece onto the v-blocks and align beneath the support plate as required. Note: care must
be taken to ensure that the V-blocks do not fall from the table. If necessary hold the configuration in position with clamps.
4.2.3. If required, rotate the hydraulic unit screw extension anti-clockwise until the support plate is closer to the workpiece. Check that the
workpiece is centred in relation to the support plate.
4.2.4. Fit handle over release valve and rotate clockwise to close valve (fig.1).
4.2.5. Place handle into handle sleeve and pump handle to apply load to the workpiece.
4.2.6. When work is done, stop pumping the handle. Slowly and carefully free load from workpiece by fitting the handle over the release
valve and turning anti-clockwise in small increments (fig.1). Note: Always keep the hydraulic unit fully retracted after use to avoid ram
corrosion.
4.2.7. If necessary, rotate the hydraulic unit screw extension clockwise to allow space for the workpiece to be removed.
4.2.8. Once the hydraulic unit has been fully retracted, remove the workpiece from the V-blocks and the table.

5. MAINTENANCE
Note: Maintenance and repair must only be carried out by qualified person. Contact your Sealey dealer for details.
5.1.
When the press is not in use, the hydraulic unit ram must be fully retracted to minimise corrosion. Remove the handle to inactivate the
press.
5.2.
Lubricate all moving parts at regular intervals.
5.3.
Always keep the press clean, dry, and protected from harsh conditions.
5.4.
Should you need to replace the oil, ensure the hydraulic unit ram is fully retracted. An excess of oil will render the press inoperative.
Use only appropriate Sealey hydraulic jack oil (Sealey Part Number: HJO500MLS/HJO5LS). DO NOT use brake fluid.
Purge the system to remove any air.
5.5.
Check your model parts information for spares.
