1. SAFETY
1.1. GENERAL SAFETY
9Familiarise yourself with the applications, limitations, and hazards peculiar to the press.
9Maintain the press in good condition (use an authorised service agent).
9Replace or repair damaged parts. Use recommended parts only. Unauthorised parts may be dangerous and will invalidate the
warranty.
9Keep the press clean for best and safest performance.
9Locate 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.
9Ensure the workpiece is correctly secured before operating the press.
9Ensure that all fittings are tight before each use.
9Remove ill fitting clothing. Remove ties, watches, rings, loose jewellery and contain long hair.
9Keep hands and body clear of the work table when operating the press.
9Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip footware.
9Keep children and unauthorised persons away from the working area.
9Securely 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.
8DO NOT operate the press if any parts are missing as this may cause failure and/or possible personal injury.
8DO NOT use the press for a task it is not designed to perform.
8DO NOT make any modifications to the press.
8DO NOT adjust or tamper with the safety valve.
8DO NOT exceed the rated capacity of the press.
8DO NOT apply off-centre loads.
8DO NOT allow the workpiece or the press plates to fall from the work table.
8DO NOT get the press wet or use in damp or wet locations or areas where there is condensation.
8DO NOT operate the press when you are tired or under the influence of alcohol, drugs or intoxicating medication.
8DO NOT climb upon the press.
8DO NOT use to compress a spring or any other item that could disengage and cause a potential hazard including personal injury.
8DO NOT stand directly in front of the loaded press and never leave a loaded press unattended.
8DO 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.
8DO 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.
2. i INTRODUCTION
Detachable pump and ram allowing hydraulics to be used for other purposes when press is not in use. Supplied with gauge.
▲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. INSTALLATION
5.1. SECURE PRESS TO THE FLOOR
WARNING! Always use another person when moving the press.
5.1.1. Move the press to the mounting location and drill four mounting holes in the feet of the press.
5.1.2. Make a template to mark the spots where the four holes will be drilled in the floor.
5.1.3. Check for any hidden wiring or cables, if needed change the location for the holes.
5.1.4. Temporarily move the press to the side.
5.1.5. Use a masonry drill bit to drill the four holes about 3” to 4” deep into the concrete or wood, as necessary.
5.1.6. Clean out the drilled holes.
5.1.7. Position the press and align the holes in the feet with the holes in the floor.
5.1.8. Use four concrete anchor bolts or lag bolts for wooden floors (not included) to secure to the floor.
NOTE: This press needs to be mounted to the floor of either concrete or wood, capable of supporting the weight of the press and any
workpiece.
WARNING! To prevent serious injury DO NOT use damaged equipment. If abnormal noise or vibration occurs have the problem
corrected before further use.

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 section1 Safety Instructions.
5.3. The transit valve on the bottom of the pump (opposite end to the handle) needs to be open during operation.
6. OPERATION
6.1. Check that the hydraulic unit is fully closed ready for operating.
6.2. Position the table at the required operating height by inserting the pins into the appropriate holes in the frame.
6.3. Position the V-block plates 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).
6.4. Operate the pump slowly until the ram is close 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.
6.5. When work is completed release the pressure using the knob with four lugs and the piston and the ram head will retract automatically.
Note: Always keep the piston retracted after use to avoid corrosion.
7. MAINTENANCE
Note: Maintenance and repair must be carried out by qualified person. Contact your Sealey stockist for details.
7.1. Check all fittings are tight before each use.
7.2. Lubricate all moving parts at regular intervals.
7.3. Always keep the press clean, dry, and protect from harsh conditions.
7.4. Should you need to replace the oil ensure the piston is fully retracted. An excess of oil will render the press inoperative.
Use only appropriate Sealey hydraulic jack oil. DO NOT use brake fluid. Contact your local Sealey stockist for details. Purge the system
to remove any air.
7.5. Check your model parts information for spares. Repair kits are available.
