SAFETY PRECAUTIONS

Due to the weight of the press, the help of an assistant will be beneficial during assembly and installation.
ALWAYS operate the press with adequate light.
Before starting work, check for signs of cracked welds, loose or missing bolts, or any other structural damage. Do not operate if any of these conditions exist.
Have repairs made only by the authorized service center.
NEVER tamper with any components. The safety valve is calibrated and sealed at the factory; do not attempt to change the setting.
Use only the recommended hydraulic oil.
The components of this press are designed to withstand the rated capacity.
DO NOT substitute any other components or exceed the rated capacity of the press.
Before applying pressure, ALWAYS ensure the workpiece is firmly secure and stable.
ALWAYS clean up spills of hydraulic oil immediately as this can be dangerous in a workshop environment.
DO NOT allow any person who is unfamiliar with hydraulic presses to use the press unless they are under direct supervision.
DO NOT stand directly in front of the press when it is in use.
ALWAYS apply the load under the center of the ram. Offset loads can damage the ram and may cause the workpiece to be ejected.
ALWAYS ensure the workpiece is properly supported by the press bed.
When using accessories such as pressing plates, be certain they are centered below the ram and are in full contact with the bed.
Parts being pressed may shatter or be ejected from the press. In the case of varied applications, it is your responsibility to always use adequate guards, and wear eye protection  and protective clothing when using this press.
Keep hands and fingers away from parts that may pinch or shift.
NEVER use extension tubes to increase the length of the pump handle.
Excessive effort can cause damage and/or accidents.
Failure to heed these warnings may result in damage to the equipment or serious personal injury.

UNPACKING

Ensure the press components suffered no damage during transit and that all components are present. Should any loss or damage become apparent, please contact your CLARKE dealer immediately.

ASSEMBLY

The press must be firmly secured to a solid level floor such as concrete, using expansion bolts (not supplied). Holes are provided in the foot sections for this purpose. Do not locate your press where it will be open to the elements, as harsh weather conditions will damage the hydraulic parts.

Due to the weight of the components, we recommend that the press is assembled by two people.

1. Attach the feet and the bottom cross member to the side supports, using the M12 nuts, bolts, and washers.

2. Add the foot braces to each side using the remaining M10 nuts, bolts, and washers.

3. Bolt the cross beam to the side supports, securing it with the M16 bolts, nuts, and washers.
   • Assemble loosely before tightening all fastenings.

4. With the help of an assistant, maneuver the frame to its intended location in the workshop.

5. Fix the 2x hooks to the moving cross beam using the nuts supplied. Take the two springs and hook them to their positions on the moving beam. Support the moving beam and attach the other end of the springs to the cross beam.

6. Take the bottle jack unit, and by pressing down on the moving cross beam against the resistance of the springs, maneuver the jack so that the jack ram sits in the socket below the cross beam.

7. Using the small hex bolt and nut, secure the jack to the beam.
   • The jack will remain self-centered during use.
   Bolt the two halves of the pressing bed together using the long bolts with nuts and spacer tubes supplied.

8. Insert the bed support pins into the holes in the side support at a height of your choosing. Then lower the pressing bed onto the pins.

PREPARATION

POSITIONING THE BED
Due to the weight of the bed, we recommend that you get assistance from another person when changing the bed height.

1. Raise one side of the bed and insert a supporting pin into the next locating hole.

2. Repeat at the other end to level the bed.
   CAUTION: IT IS SAFER AND EASIER IF THE BED HEIGHT IS ONLY RAISED OR LOWERED ONE HOLE AT A TIME, WORKING ALTERNATELY  FROM ONE SIDE AND THEN THE OTHER UNLESS AN ASSISTANT IS AVAILABLE TO SUPPORT THE WEIGHT OF THE BED WHILE THE PINS ARE  INSERTED.

3. Position the bed at the desired height, so that it will be as close as possible to the ram when the workpiece is mounted on it.

OPERATION

WARNING: FAILURE TO HEED THE WARNINGS ON PAGE 3 MAY RESULT IN DAMAGE TO THE EQUIPMENT OR COMPONENT FAILURE RESULTING  IN PROPERTY DAMAGE, PERSONAL, OR EVEN INJURY. NEVER USE EXTENSIONS TO THE RAM PUMPING HANDLE

1. The press is now ready for use. Place the workpiece on the bed. It must be completely stable and supported by packing or shims where required. A pair of pressing plates are supplied, which lay flat on the bed. Place the 0workpiece on these to give it stability.
   CAUTION: DO NOT POINT LOAD THESE ACCESSORIES AS THEY ARE NOT DESIGNED TO TAKE THE FULL FORCE OF THE RAM IN ONE SPOT.  ENSURE THEY ARE ADEQUATELY SUPPORTED.
   NOTE: Any packing pieces or shims used MUST be capable of withstanding the pressure that will be brought to bear, and MUST be of sufficient size with sufficient surface area, so as to avoid the possibility of slipping or springing out. Mating surfaces MUST be horizontal so that the force being exerted will NOT be at an angle.

2. Using the crimped end of the handle, 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. Position the workpiece so that the desired point of contact is directly beneath the center 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.

6. Continue to pump the handle and constantly monitor the process, ensuring the ram and work remain completely in line and there is no risk of slipping.

7. When the task is complete, turn the release valve anticlockwise in small increments to release ram pressure and allow the removal of the workpiece.

MAINTENANCE

ROUTINELY
A visual inspection must be made before the use of the press, checking for leaking hydraulic fluid and damaged, loose, or missing parts.
Owners and/or users should be aware that the repair of this equipment requires specialized knowledge and facilities. It is recommended that a routine inspection of the press be made and any defective parts are replaced with genuine CLARKE parts.
If there 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 to protect the moving parts.

PERIODICALLY
Periodically check the press frame to make sure all bolts are tight and inspect for cracked welds, bent, loose or missing parts. If corrosion is found it should be removed completely and the paint restored.
Check the hydraulic jack for leaks. Replace or properly repair any damaged or leaking hydraulic components before using. In the event of leaking seals, oil can be topped up via the plug on the jack. Oil should be level with the bottom of the hole. If necessary top up with CLARKE hydraulic oil, Part No. 3050830. This task is carried out with the ram fully retracted.
In the event of leakage, oil can be topped up by removing the filler plug on the reservoir and topping up level with the plug.

DISPOSAL OF UNWANTED MATERIALS

One of the most damaging sources of environmental pollution is oil products.
Never throw away used oil with domestic refuse or flush it down a sink or drain.
Collect any oil in a leak-proof container and take it to your local waste disposal site.
Should hydraulic components become completely unserviceable and require disposal, draw off the oil into an approved container and dispose of theproduct and the oil according to local regulations.
