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 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

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

that you get assistance during assembly.

IMPORTANT: The press should be firmly secured to a firm and level floor

using expansion bolts (not supplied). Holes are provided in the base

supports for this purpose.

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

as harsh weather conditions will damage the hydraulic parts.

1. With the help of an assistant,

attach the base supports to the

side posts using the nuts, bolts and

washers.

2. Add the stay bars to each side

and bolt into place.

3. Bolt one of the upper cross

members into place to connect

the side posts together.

4. Take the second upper cross

member and the ram carrier and

tie the two cross members

together using the ram carrier.

Then bolt the second cross

member to the side posts as

shown.

• The ram carrier can slide along the cross members.

5. Fit and tighten the locking bolts

loosely to stop the ram carrier

from sliding to and fro.

6. Lift the complete press assembly

upright and manoeuvre it to its

intended location in the

workshop.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Servi[email protected]

7. Bolt the pump assembly to one of

the side posts. Thread the fixing

bolts though the side post from

the inside as shown.

• This will become the right hand

side of the press.

8. Lower the ram through the hole in

the moving ram carrier and

secure in position using the

locking collar.

9. Assemble the pressing bed using

the four spacers and the 140mm

bolts with nuts and washers.

10. Insert the bed support pins into

the holes in the frame side

supports at a height of your

choosing.

11. Lift the pressing bed into position

on the pins.

• Due to the weight of the bed,

we recommend that you get

assistance from another

person.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

12. Connect the hydraulic hose to the

ram cylinder, sealing the joint with

PTFE tape and tighten using two

open ended spanners.

13. The pressure gauge is sealed for

transit and it will be necessary to

make a small hole in the pressure

gauge safety bung with a short

pin or nail before use.

• Do not use a long nail as you

may damage the internal

components of the gauge.

14. Bolt the pressure gauge into

position on the hydraulic ram.

• We recommend sealing the

thread with PTFE tape. Take

care not to let any oil escape

while connecting the hose.

15. Top up the hydraulic oil to the

lower level of the filler plug.

PREPARATION FOR USE

1. Insert the pump handle into the

actuating lever.

2. Purge any air from the system by

opening the release valve

(turning the control knob anti-

clockwise) and pumping several

full strokes to eliminate any air

bubbles. Close the valve using the

control knob (clockwise).

POSITIONING THE BED

IMPORTANT: Due to the weight of the bed, we recommend that you get

assistance from another person when adjusting the bed height.

1. Position the bed so that it will be as close as possible to the ram when the

workpiece is mounted on it.

2. Raise one side of the bed and insert a bed supporting pin into the next

locating hole.

3. Repeat at the other end to level the bed.

4. Repeat until the bed is at the required height, with the bed supporting pins

secured by the spring clips.

POSITIONING THE RAM

1. Loosen the locking bolts and

position the ram as required by

sliding the carriage along the

cross-beam.

2. Lock it in position with the locking

bolts.

• Always position the ram

directly above the workpiece

and do not position it outside

the range indicated by the

maximum travel limit labels.

CAUTION: THE BED HEIGHT SHOULD ONLY BE RAISED OR LOWERED ONE

HOLE AT A TIME, WORKING ALTERNATELY FROM ONE SIDE AND THEN THE

OTHER, FAILURE TO WORK IN THIS WAY MAY CAUSE THE BED TO FALL

AND CAUSE INJURY TO THE OPERATOR.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

POSITIONING THE PRESSING BLOCKS

The pressing blocks can be placed

on the bed to suit the work.

Check all parts are secure and

correctly aligned before using the

press.

OPERATION

1. Place the workpiece on the bed. It must be completely stable and

supported by packing or shims where required. Pressing plates are

supplied, which locate on the bed. Place the workpiece on these to give it

stability.

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

the control knob 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

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. NEVER USE EXTENSIONS TO THE

PUMPING HANDLE.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Servi[email protected]

constantly monitor the process, ensuring the ram and work remain

completely in line and there is no risk of slipping.

6. Observe the reading on the pressure gauge and take care not to exceed

the rated working pressure of the press.

• The scale from 20 metric tonnes upward is highlighted in red, indicating

pressure being applied above the rated maximum working pressure.

7. When the process is complete, turn the release valve control knob

anticlockwise in small increments to release ram pressure and allow

removal of the workpiece.

MAINTENANCE

ROUTINELY

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 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.

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.

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.

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