SAFETY PRECAUTIONS

1. Due to the weight of the press, lifting equipment and the help of an

assistant will be required during installation. Fix the press to the floor using

suitable anchor bolts.

2. Before starting work, check for signs of cracked welds, loose or missing

bolts, damaged screen, or any other damage. Do not use if any of these

conditions exist. Have repairs made only by authorised service centre.

3. Before work, always ensure that hydraulic hoses and couplings are

completely sound.

4. NEVER tamper with the press components or modify them. The safety valve

is set and sealed at the factory; do not attempt to adjust the setting.

5. Use only the recommended hydraulic oil.

6. The components of this press are designed to withstand the rated load. Do

not substitute any other components or exceed the rated load of the press.

7. Before applying pressure, ensure the workpiece is firmly secure and stable.

8. ALWAYS clean up spills of hydraulic oil immediately as this can be

dangerous in a workshop environment.

9. Do not let any person who is unfamiliar with hydraulic presses use the press

unless they are under direct supervision.

10. Keep children and unauthorised personnel away from the work area.

11. ALWAYS position the (optional) safety screen directly front of the workpiece.

12. 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.

13. ALWAYS ensure the work piece is properly supported by the press bed.

14. When using accessories such as pressing plates, be certain they are

centered below the ram and are in full contact with the bed.

15. Parts being pressed may shatter or be ejected from the press. Always use

adequate guards and wear eye protection and protective clothing when

using this press.

16. Keep hands and fingers away from parts that may pinch or shift.

17. NEVER use extension tubes to increase the length of the pump handle or

foot pedal. Excessive effort can cause damage and/or accidents.

18. Wear ANSI approved impact safety goggles heavy duty work gloves.

19. Failure to heed these warnings may result in damage to the equipment, or

serious personal injury.

PREPARATION FOR USE

LOCATING THE PRESS

Using suitable lifting equipment if required, lift the frame assembly upright and

manoeuvre it to its intended location in the workshop.

The press must be firmly secured to a firm and level floor using expansion bolts

(not supplied). Holes are provided in the feet for this purpose.

Do not locate your press where it will be exposed to the elements as harsh

weather conditions will damage the hydraulic parts.

FITTING THE WINCH

During transit, the winch is positioned

at 180oto its working position inside

the frame and must be correctly

mounted.

1. Turn the winch and bracket

around and re-fit to the frame

with the bolts and washers

supplied, noting that the handle

will be outside the frame for

operation.

FITTING THE HANDWHEEL

The handwheel which is used to

position the ram within the frame is

supplied loose and requires fitting.

WARNING: DUE TO THE WEIGHT OF THE PRESS, LIFTING EQUIPMENT OR THE

HELP OF AN ASSISTANT WILL BE REQUIRED DURING INSTALLATION.

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

1. Fit the thrust bearing to the end of

the axle.

2. Check that the direction of the

thrust bearing is with the silver

metal side facing outwards.

3. Fit the key into the slot in the shaft

and tap it into place.

4. Install the handwheel onto the

shaft, lining up the slot in the

wheel with the retaining key.

5. Secure the handwheel with the

spring washer, flat washer and

cross-headed screw supplied.

PROTECTIVE SCREEN (OPTIONAL)

A protective screen CPS50T is

available from your CLARKE dealer,

part no: 7615262.

1. Bolt the protective screen

brackets to the pressing bedplate.

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

2. Fit the protective screen assembly

to the brackets and ensure it can

be set in one of the available

positions using the latches on

each side.

PURGING THE HYDRAULIC SYSTEM

1. Open the release valve by turning

anti-clockwise.

2. Pump the handle or foot pedal

several full strokes to eliminate any

air bubbles from the system.

3. Close the release valve, turning

clockwise.

POSITIONING THE PRESSING BED

1. Use the winch to raise the pressing

bed into a suitable position.

• The arrows on the winch

indicate the direction of

movement.

• The pressing bed should be as

close as possible to the ram

when the workpiece is

mounted on it.

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

2. When satisfied that the bed is at

the correct height insert the

locking pins into their positions

and secure with the butterfly clips.

POSITIONING THE RAM

1. Position the carriage horizontally

along the cross-beam using the

adjusting handwheel on the side

of the press.

• Always position the ram

directly above the workpiece

which should be as close to

the centre of the press as

possible.

POSITIONING THE PRESSING BED BLOCKS

The bed blocks can be placed on

the bed with either the flat face or

the V-supports facing upwards.

They are prevented from slipping out

of position by the retaining pins which

drop down within the confines of the

bed side members.

Check all parts are secure and

correctly aligned before using the

press.

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

OPERATION

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

supported by packing or shims where required. Pressing plates (bed blocks)

are supplied, which locate on the bed. Place the workpiece on 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

clockwise until tightly closed.

3. Select either SLOW SPEED or FAST

SPEED using the knob on the side

of the pump cover.

• Fast speed allows faster

movement but greater effort

will be required.

4. Pump the handle or foot pedal to

bring the ram very lightly into

contact with the workpiece.

5. 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.

6. When satisfied that the workpiece

is correctly aligned and is

completely stable in that position,

slide the protective screen (if

fitted) into position before starting

any pressing.

• The latches will support the

screen in a selection of

positions.

CAUTION: DO NOT POINT LOAD SUCH ACCESSORIES AS THEY ARE NOT

DESIGNED TO TAKE THE FULL FORCE OF THE RAM IN ONE SPOT. ENSURE

THEY ARE ADEQUATELY SUPPORTED.

7. Slowly pump the handle or foot pedal so that the ram begins to exert

pressure on the workpiece.

8. Continue to pump the handle and constantly monitor the pressing,

ensuring the ram and work remain completely in line with no risk of slipping.

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

the rated working pressure of the press.

• The scale from 50 metric tonnes upward is highlighted in red, indicating

pressure is being applied above the rated maximum working pressure.

10. When the pressing task is complete, turn the release valve control knob

anticlockwise in small increments to release ram pressure and allow

removal of the workpiece and lower the protective screen.
