SAFETY PRECAUTIONS

• Due to the weight of the press, the help of an assistant will be beneficial

during assembly or when moving the press around.

• Always operate the press on a suitably strong bench 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 authorised service centre.

• Before work, always ensure that hydraulic hoses and couplings are

completely sound.

• Never tamper with the press 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 centre of the ram. Offset loads can

damage the ram and may cause the work piece to be ejected.

• Always ensure the work piece 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.

ASSEMBLY

The following safety symbols are to be found on the machine.

Ensure the press and its 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.

IMPORTANT: Due to the weight of the press components, we recommend

that you get assistance during assembly.

IMPORTANT: Do not locate your press where it will be open to the elements,

as severe weather conditions will damage the hydraulic parts.

1. Bolt the bottom cross members to

the side supports using the nuts,

bolts and washers.

2. Attach the feet to the side

supports using the nuts, bolts and

washers.

3. Bolt the upper crossmembers to

the side supports using the nuts,

bolts and washers.

• Assemble loosely before evenly

tightening all the bolts at each end

with both spring and flat washers.

4. Lift the frame assembly upright

and manoeuvre it to its intended

location in the workshop.

5. Bolt the ram baseplate to the

upper cross beams from below.

6. Insert the ram through the hole in the base plate from above and screw

into position.

Wear eye

protection.

7. Unfasten the protective hose cap

and screw the hose onto the

threaded connection of the

hydraulic ram.

• We recommend sealing the thread

with PTFE tape. Take care not to let

any oil escape while connecting

the hose.

8. Unscrew the filler plug on the end

of the cylinder and check that oil

can be seen at the bottom of the

aperture. Top up if necessary.

9. Screw the pump handle into the

pump actuating lever.

PURGING THE SYSTEM

1. Before using the press, purge any

air from the system by opening

the release valve (turning it anti-

clockwise) and pumping several

full strokes to eliminate any air

bubbles.

2. Close the release valve.

FITTING THE RAM EXTENSIONS

1. Fit the ram extensions and

pressure cap as required.

2. Check all parts are secure and

correctly aligned before using the

press.

The press is now ready for use.

OPERATION

1. Place the workpiece on the

pressing plates supplied. It must

be completely stable and

supported by packing or shims

where required. Place the

workpiece on a combination of

these to give it stability.

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. 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 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 anti-clockwise in

small increments to release ram pressure and allow removal of the

workpiece.

WARNING: NEVER USE EXTENSIONS TO THE RAM PUMPING HANDLE

MAINTENANCE

INSPECTION AND STORAGE

1. A visual inspection should be made before each use of the press, checking

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

2. 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.

3. 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.

4. 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

1. Check the frame to make sure all bolts are tight and inspect for cracked

welds, bent, loose or missing parts.

2. Check the hydraulic connections 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 end of the pump.

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.

3. If any rust is apparent it must be removed completely and the paint

restored.

DE-COMMISSIONING THE PRODUCT

Should the product become completely unserviceable and require disposal,

draw off the oil into an approved container and dispose of the product and

the oil according to local regulations.
