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

• Never tamper with the press. The safety valve is calibrated and sealed at the

factory; do not attempt to change the setting.

• Use only the recommended hydraulic oil.

• Components of this press are specially designed to withstand the rated

capacity. Do not substitute bolts, pins, or any other components.

• Always apply the load under the centre of the ram. Offset loads can

damage the ram or ram mount and may cause the work piece to eject.

• Before operating, check for signs of cracked welds, bent bed pins, 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.

• Remove load from press bed before attempting to adjust bed height.

• Press only on a work piece supported by the press bed.

• When using accessories such as arbor plates, be certain they are centered

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

• Parts being pressed may splinter, shatter, or be ejected from the press. Due to

varied applications, it is your responsibility to always use adequate guards,

wear eye protection and protective clothing when operating this press.

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

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

failure resulting in property damage, personal, or even fatal injury.

• DO NOT use extension tubes on the pump handle. Excessive effort can cause

damage and/or accidents.

ASSEMBLY

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: We strongly recommend that the press 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 severe weather conditions will damage the hydraulic parts.

1. Attach the feet and the bottom

cross member to the side

supports, using the nuts, bolts and

washers.

2. Add the stay bars to each side

and bolt into place.

3. Bolt one of the cross beams to the

side supports, Attach the ram

baseplate to the cross beam,

securing it with the socket

headed bolt.

4. Add the other cross beam by

sliding it along the ram baseplate

from one end.

5. Assemble loosely before

tightening all the bolts at each

end with both spring and flat washers. Position the ram baseplate centrally

and lock in position.

6. With the help of an assistant, lift the frame assembly upright and

manoeuvre it to its intended location in the workshop.

7. With the upper ring already

screwed home onto the ram

body as supplied, lower the ram

through the hole in the base plate

and secure in position using the

locking collar.

8. Insert the bed support pins into

the holes in the side support at a

height of your choosing. Then

lower the bed frame onto the

pins.

9. Screw the pressure gauge to the

connecting nut on top of the ram

cylinder. Seal the thread with PTFE

tape, ensuring it is tight when the

gauge is facing the front of the

press.

10. Pass the hydraulic hose through

the gap between the two cross

beams. Unfasten the protective

hose caps and screw the hose

onto the threaded connection of

the hydraulic ram.

11. We recommend sealing the thread with PTFE tape. Take care not to let any

oil escape while connecting the hose.

12. Unscrew the filler plug on the end

of the cylinder and remove the

dipstick to check that the pump is

filled with oil up to the raised mark

the dipstick.

13. Attach the pump support plate to

the right-hand side support using

the fixing bolts, nuts and washers,

ensuring it is level before

tightening the bolts.

14. Bolt the pump to the support

plate using the socket head bolts

from below, then screw the pump

handle into the pump actuating

lever.

15. Bolt the mandrell storage bracket

to the side of the frame using the

bolts supplied.

16. Store the mandrells (including the

adaptor) in their positions on the

bracket.

PUMP/RAM OPERATION

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. Check all parts are secure and

correctly aligned before using the

press.

• The press is now ready for use.

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 at the desired height, 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 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 desired height, with the supporting pins fully

‘home’.

POSITIONING THE RAM

The ram can positioned as required

by sliding it along the cross-beam.

Lock it in position with the socket

head adjusting bolt on each side.

• Always position the ram directly

above the workpiece.

FITTING THE MANDRELLS OR PRESSURE CAP

Four mandrells are provided, any of

which may be connected to the end

of the ram using the adaptor

supplied.

Alternatively, the basic ram pressure

cap can be fitted as shown. Secure

the pressure cap by tightening the

grub screw with a suitable hex key.

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 Servi[email protected]

If one of the mandrells is required, the

adaptor must be fitted instead of the

pressure cap. Secure the adaptor by

tightening the grub screw with a

suitable hex key as previous.

Select your mandrell depending

upon the size of the workpiece

bearing surface.

The mandrell can then be pushed

into the adaptor where the built-in

spring clip will hold it in place.

Store the mandrells in their positions

on the mounting bracket when not in

use.

OPERATION

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

supported by packing or shims where required. Steel pressing plates are

supplied, which locate on the bed. 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.

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.

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

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.

WARNING: NEVER USE EXTENSIONS TO THE RAM PUMPING HANDLE

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

• 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.
