2. Close the release valve by turning 

it clockwise until tightly closed.

3. Pump the handle to bring the ram 

very lightly into contact with the 
workpiece.

4. Manoeuvre the workpiece or slide 

the ram to one side so that the 
desired point of contact is directly 
beneath the centre of the ram.

5. When satisfied that the workpiece 

is correctly aligned and is completely stable in that position, slowly pump 
the handle so that the ram begins to exert pressure on the workpiece.
Continue to pump the handle whilst standing to the side. Do NOT stand 
directly in front of the work, and constantly monitor the process, ensuring 
the ram and work remain completely in line and there is no risk of slipping.

6. When the process is complete, turn the release valve anticlockwise in small 

increments to release ram pressure and allow removal of the workpiece.

MAINTENANCE

• A visual inspection must be made before each use of the press, checking for 

leaking hydraulic fluid and damaged, loose, or missing parts.

• Owners and/or users should be aware that repair of this equipment requires 

specialised knowledge and facilities. It is recommended that a thorough 
annual inspection of the press be made and that any defective parts be 
replaced with genuine Clarke parts.

• Any press which appears to be damaged in any way, is found to be badly 

worn, or operates abnormally SHOULD BE REMOVED FROM SERVICE until the 
necessary repairs are made.

• If the press is not to be used for any length of time, store it with the ram piston 

withdrawn and the operating handle in the lowered position to protect the 
moving parts.

PERIODICALLY

• Check the press frame to make sure all bolts are tight and inspect for 

cracked welds, bent, loose or missing parts.
