Clean out the drilled holes.
Position the press and align the holes in the base section with the holes in the fl oor.
Use four concrete anchor bolts or lag bolts for wooden fl oors, (not included), to secure to the fl oor.
WARNING! To prevent serious injury DO NOT use damaged equipment. If abnormal noise or vibration occurs have the problem corrected. Ensure the mounting surface is capable of withstanding the weight of the press and the workpieces.
BEFORE FIRST USE
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 fl ex or suddenly “give way” causing danger to operator or the component. Also ensure you have read and understood section 1 Safety Instructions.

OPERATION

TRANSIT PLUG
MPORTANT: The transit plug (fig 2) MUST be open for use. Only to be closed for transit.
To open the transit valve unscrew by turning counterclockwise.
SETTING THE BED FRAME HEIGHT
Turn the hand winch (#12) until the cables just takes the weight of the bed frame (#31).
Remove the circlips (#25) from the back of the pins (#44) and withdraw the pins, storing them in a secure location.
Use the hand winch (#12) to raise or lower the bed frame (#31) to the desired height.
Re-insert the pins (#44) and the circlips (#25).
Slacken off the hand winch (#12) so that the pins (#44) are taking the full weight of the bed frame (#31).
Check that the release valve on the hydraulic unit is fully closed and ready for operating.
Position the V blocks (#32) 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-center loads.
- WARNING! Monitor the pressure gauge during operation to ensure that the rated capacity of the press is not exceeded.
When the operation is complete turn the release valve anti-clockwise to release the pressure. The piston and the ram head will
retract automatically.
NOTE: Always keep the piston retracted after use to avoid corrosion.

MAINTENANCE

NOTE: Maintenance and repair must be carried out by qualified personnel. Contact your Sealey stockist for details.

Check all fittings are tight before each use.
Lubricate all moving parts at regular intervals.
Always keep the press clean, dry, and protect from harsh conditions.
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.
