2. INTRODUCTION & SPECIFICATIONS
1. SAFETY INSTRUCTIONS
2.1. GENERAL INFORMATION
Economy model is suitable for the serious enthusiast or occasional professional use. Made from a high quality steel with a powder coated finish
to help corrosion resistance.
 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.
3. ASSEMBLY
Unpack the product and check contents. Should there be any damaged or missing parts contact your supplier immediately. Take care to
ensure safety when removing post section and bottle jack from packing as these units are very heavy.
3.1. Use the parts diagram as your guide to assembly. Lay all parts and assemblies out before beginning. The following procedure is
recommended:
3.2. Attach one of the feet (16) to one of the upright sections (9) and to the base support (15) using M12x30 bolts (17), washers (18), and
nuts (19) to secure the parts. Repeat with the other foot (16), attaching it to the remaining upright section (9) and to the base support
(15). The bolts should not be fully tightened.
3.3. Attach the braces (22) to the feet (16) and to the uprights (9) using M12x30 bolts (17), washers (18) and nuts (19). The bolts
should not be fully tightened.
3.4. Place the press in an upright position and insert the support pins (14) into the uprights (9) so that they are directly opposite each
other. Place the table (13) over the uprights and onto the support pins (14).
3.5. Attach the upper support (1) using the M16x30 bolts (2), nuts (4), and washers (3) to the uprights. The bolts should not be fully
tightened.
3.6. Check the assembly is squared, centred and correctly aligned. Fully tighten all the bolts.
Familiarise yourself with the applications, limitations and hazards of the press.
 Maintain the press in good condition (use an authorised service agent).
Replace or repair damaged parts. Use recommended parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
Keep the press clean for best and safest performance.
Locate the press in an adequate working area for its function, keep area clean and tidy and free from unrelated materials and ensure
there is adequate lighting.
Ensure the workpiece is correctly secured before operating the press.
 Ensure that all fittings are tight before each use.
WARNING! Always wear approved eye or face protection when operating the press. A full range of personal safety equipment is available
from your Sealey dealer.
Remove ill fitting clothing. Remove ties, watches, rings, other loose jewellery and contain long hair.
Keep hands and body clear of the table when operating the press.
 Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
Keep children and unauthorised persons away from the working area.
 DO NOT operate the press if any parts are missing as this may cause failure and/or possible personal injury.
 DO NOT use the press for a task it is not designed to perform.
 DO NOT make any modifications to the press.
 DO NOT exceed the rated capacity of the press.
 DO NOT apply off-centre loads.
 DO NOT allow the workpiece or the V-blocks to fall from the table.
 DO NOT get the press wet or use in damp or wet locations or areas where there is condensation.
 DO NOT operate the press when you are tired or under the influence of alcohol, drugs or intoxicating medication.
 DO NOT climb upon the press.
 DO NOT use the press to compress a spring or any other item that could disengage and cause a potential hazard including personal injury.
 DO NOT stand directly in front of a loaded press and never leave a loaded press unattended.
 DO NOT allow untrained persons to operate the press.
 WARNING: DO NOT top up hydraulic unit with brake fluid, or any other fluid other than a good quality hydraulic oil (Sealey Part
Number: HJO500MLS/HJO5LS) as this may cause serious damage to the hydraulic unit and will invalidate the warranty.
When not in use, release pressure from the hydraulic unit and clean the press. Stand or store the V-blocks in a safe location.

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.
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.
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).
