Thank you for purchasing a Sealey product. Manufactured to a high standard, this product will, if used according to these instructions,
and properly maintained, give you years of trouble free performance.
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS. USE
THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR
PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.
1. SAFETY
9 Familiarise yourself with the applications, limitations and hazards of the press.
9 Maintain the press in good condition (use an authorised service agent).
9 Replace or repair damaged parts. Use recommended parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
9 Keep the press clean for best and safest performance.
9 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.
9 Ensure the workpiece is correctly secured before operating the press.
9 Ensure that all fittings are tight before each use.
9 Remove ill fitting clothing. Remove ties, watches, rings, other loose jewellery and contain long hair.
9 Keep hands and body clear of the table when operating the press.
9 Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
9 Keep children and unauthorised persons away from the working area.
9 Securely attach the press to a flat, firm, level surface capable of supporting the weight of press and any workpiece taking into account
clearance for workpieces.
9 When not in use, release pressure from the hydraulic unit and clean the press. Stand or store the V blocks in a safe location.
8 DO NOT operate the press if any parts are missing as this may cause failure and/or possible personal injury.
8 DO NOT use the press for a task it is not designed to perform.
8 DO NOT make any modifications to the press.
8 DO NOT exceed the rated capacity of the press.
8 DO NOT apply off-centre loads.
8 DO NOT allow the workpiece or the v blocks to fall from the table.
8 DO NOT get the press wet or use in damp or wet locations or areas where there is condensation.
8 DO NOT operate the press when you are tired or under the influence of alcohol, drugs or intoxicating medication.
8 DO NOT climb upon the press.
8 DO NOT use the press to compress a spring or any other item that could disengage and cause a potential hazard including personal injury.
8 DO NOT stand directly in front of a loaded press and never leave a loaded press unattended.
8 DO NOT allow untrained persons to operate the press.
WARNING! Always wear approved eye or face protection when operating the press. A full range of personal safety equipment is available
from your Sealey stockist.
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.
WARNING! Always position the press against a wall. If the press is situated in the open workshop, it is essential that a guard be
placed at the rear of the unit. This will prevent injury to bystanders in the event of the work piece ejecting suddenly.
WARNING! The warnings, cautions and instructions in this manual cannot cover all possible conditions and situations that may occur.
It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be
applied by the operator.
▲ DANGER! The press is top heavy. If it requires moving after assembly or for relocation, use suitable slings around the top crossbeam,
or lift direct with a forklift with the forks located under the top crossbeam. DO NOT use a pallet truck.

4. ASSEMBLY
4.1. REFER TO THE ATTACHED PARTS LIST
9 Seek assistance of another person on assembly of heavy parts.
9 Assemble press, if possible, in close proximity to where the press will be located.
5. INSTALLATION
5.1. SECURE THE PRESS TO THE FLOOR
WARNING! Always use the assistance of another person when moving the press.
5.1.1. Move the press to the mounting location and spot mark through fixing holes in base section onto the floor.
5.1.2. Check for any hidden wiring or cables.
5.1.3. Temporarily move the press to the side.
5.1.4. Use a masonry drill bit to drill the four holes about 3” to 4” deep into the concrete or wood, as necessary.
5.1.5. Clean out the drilled holes.
5.1.6. Position the press and align the holes in the base section with the holes in the floor.
5.1.7. Use four concrete anchor bolts or lag bolts for wooden floors, (not included), to secure to the floor.
WARNING! To prevent serious injury DO NOT use damaged equipment. If abnormal noise or vibration occurs have the problem corrected.
5.2. BEFORE FIRST USE
5.2.1. Before operating the press, purge the hydraulic system of the hydraulic unit, in order to eliminate any air that may have accumulated
during transit. Open the release valve and pump the handle several times and close the release valve. Should the system malfunction
at any time, repeating this process may resolve the problem.
▲ DANGER! This model is purposefully 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 ex or suddenly “give way” causing danger to
operator or the component. Also ensure you have read and understood section 1 Safety Instructions.
6. OPERATION
6.1. Check that the hydraulic unit is fully closed ready for operating.
6.1.1. Position the table at the required operating height by inserting the pins into the appropriate holes in the frame.
6.1.2. Position the V blocks or press tools to be used onto the table and align beneath the ram. Place workpiece onto the table or V blocks and
align beneath the ram as required. Note: Care must be taken to ensure a V block does not fall from the press table. If necessary hold the
configuration in position with clamps (not supplied).
6.1.3. Operate the pump slowly until the ram is close to or just touching the workpiece. Before applying real pressure to the workpiece recheck
the alignment with the ram and ensure that the workpiece and press tools are supported in such a way that they cannot flex to breaking
point. DO NOT exceed the stroke indicated on the label or the red mark on the piston and DO NOT apply off centre loads.
6.1.4. When work is complete release the pressure by fitting the handle over the release valve and turning anti-clockwise in small increments.
6.1.5. Once the hydraulic unit has been fully retracted, remove the workpiece from the V blocks and the table.
Note: Always keep the piston retracted after use to avoid corrosion.
7. MAINTENANCE
NOTE: Maintenance and repair must only be carried out by qualified person. Contact your Sealey stockist for details.
7.1. 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.
7.2. Lubricate all moving parts at regular intervals.
7.3. Always keep the press clean, dry, and protected from harsh conditions.
7.4. 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.
7.5. Check your model parts information for spares.
