1. SAFETY
1.1. GENERAL SAFETY
Familiarise yourself with the applications, limitations, and hazards peculiar to 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.
Remove ill fitting clothing. Remove ties, watches, rings, loose jewellery and contain long hair.
Keep hands and body clear of the work table when operating the press.
Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip footware.
Keep children and unauthorised persons away from the working area.
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.
When not in use, release pressure from the hydraulic unit and clean the press. Stand or store the V blocks in a safe location.
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 adjust or tamper with the safety valve.
DO NOT exceed the rated capacity of the press.
DO NOT apply off-centre loads.
DO NOT allow the workpiece or the press plates to fall from the work 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 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 the loaded press and never leave a loaded press unattended.
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.
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 workpiece 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.

5. INSTALLATION
▲DANGER! Models are 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.
5.1. SECURE PRESS TO THE FLOOR
DO NOT attempt to move assembled press manually. When moving the press follow the instructions as detailed in Section 1.
5.1.1. Move the press to the mounting location, and spot mark through fixing holes in base section (#70) onto the floor.
5.1.2. Check for any hidden wiring or cables, if needed change the location for the holes.
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” (75 to 100mm) 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.
WARNING! Ensure the mounting surface is capable of withstanding the weight of the press and workpieces.
5.2. BEFORE FIRST USE
5.2.1. Before operating the press, purge the hydraulic system in order to eliminate any air that may have built up 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! Models are 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 section 1 Safety Instructions.
6. OPERATION
6.1. SETTING THE BED FRAME HEIGHT
6.1.1. Turn the hand winch handle (#21) until the cables just takes the weight of the bed frame (#28).
6.1.2. Remove the retaining clips (#26) from the back of the pins (#27) and withdraw the pins, store in a secure location.
6.1.3. Use the hand winch handle (#21) to raise or lower the bed frame (#28) to the desired height.
6.1.4. Re-insert the pins (#27) and the retaining clips (#26).
6.1.5. Slacken off the hand winch (#21) so that the pins (#27) are taking the full weight of the bed frame (#28).
6.2. Check that the release valve on the hydraulic unit is fully closed, ready for operating.
6.3. Position the V-block (#4) 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).
WARNING! DO NOT apply off centre loads.
6.4. Connect the air supply to the foot pedal (#79) quick coupler (male) (#81).
6.5. Use either of the handles or the foot pedal to lower the ram to the workpiece.
WARNING! Monitor the pressure gauge during operation to ensure that the rated capacity of the press is not exceeded.
6.6. When the operation is complete turn the release valve anti-clockwise to release the pressure. The piston and the ram head will
retract automatically.
6.7. Disconnect the air supply.
NOTE: Always keep the piston retracted after use to avoid corrosion.
