SAFETY PRECAUTIONS

1. During assembly or if the press is moved, always call for the help of an

assistant, do not manhandle single-handedly.

2. Ensure the press is bolted down onto a solid, flat surface.

3. Ensure the press is located on firm level ground with adequate light.

4. Before applying a load, ensure all press bed support pins are fully

engaged.

5. Ensure that hydraulic hoses and couplings are completely sound.

6. Before use, always ensure the workpiece is firmly secure and stable

7. Always clean spills of hydraulic oil immediately as this can be dangerous in

a workshop environment.

8. Do not exceed the rated capacity of the press.

9. Do not allow any person who is inexperienced in the use of hydraulic

presses, to use the press unless they are under direct supervision.

10. Do not allow anyone to work directly in front of the press when it is in use.

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

the factory; do not attempt to change the setting.

12. Use only the recommended hydraulic oil.

13. Components of this press are specially designed to withstand the rated

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

14. 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.

15. 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.

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

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

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

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

19. 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.

ASSEMBLY

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. With the help of an assistant,

attach the feet to the frame using

the nuts, bolts and washers.

2. Add the stay bars to each side

and bolt into place.

3. Lift the frame assembly upright

and manoeuvre it to its intended

location in the workshop.

4. With the help of an assistant, install

the ram support carriage into the

upper frame section by

assembling the baseplate, the

two axles and the four sprung

locking bolts/springs as shown in

Fig 2.

5. Tighten the locking bolts loosely so

that the carriage can still move to

and fro along the frame.

6. The hydraulic hoses must be

correctly installed within the

frame. Check that both the hoses

pass through the supporting rings

and that the T-connector sits

upright when the connecting

parts are fitted to the supporting

bracket but do not tighten at this

stage.

7. Fit the pressure gauge to the

connecting nut, sealing the

thread with PTFE tape.Check the

gauge is upright before tightening

the nut with a 19 mm spanner.

8. 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.

9. Lower the ram through the hole in

the moving carriage and secure

in position using the locking collar.

10. Connect the hydraulic hose to the

ram cylinder, sealing the joint with

PTFE tape, and tighten using two

open spanners.

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

11. Bolt the hydraulic pump into

position on the side of the frame

using the fixing bolts, nuts and

washers.

12. Ensuring that the hydraulic hose

passes through the retaining loop

on the frame, unfasten the

protective hose cap and screw

the hose onto the threaded

connection of the hydraulic

pump.

13. We recommend sealing the

thread with PTFE tape. Take care

not to let any oil escape while

connecting the hose.

14. Insert the bed support pins into

the holes in the frame side

supports at a height of your

choosing. Secure them in position

using the spring clips.

15. Lift the bed frame into position on

the pins.

IMPORTANT: Due to the weight of the

bed, we recommend that you get

assistance from another person.

ADDING A MANDREL SET

A mandrel set (including storage

bracket and pressure plate) is not

supplied with the press but is

available as Clarke part no 7615062.

1. Bolt the mandrel storage bracket

to the side of the frame using the

bolts supplied.

2. Store the mandrels (including the

adaptor) in their positions on the

storage bracket.

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

PREPARATION FOR USE

1. Insert the pump handle into the

pump 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.

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 held

by the spring clips.

POSITIONING THE RAM

1. Position the ram as required by

sliding the carriage along the

cross-beam. Lock it in a static

position with the four sprung

locking bolts.

• Always position the ram directly

above the workpiece.

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 [email protected]

FITTING THE MANDRELS

If a set of mandrels is available, any

one may be connected to the end

of the ram using the adaptor

supplied.

Alternatively, the basic pressure cap

can be fitted as shown. Secure the

pressure cap by tightening the grub

screw with a suitable hexagonal key.

To install a mandrel, the adaptor must

be fitted instead of the pressure cap.

Secure the adaptor by tightening the

grub screw with a suitable hexagonal

key as previous.

Select your mandrel depending

upon the size of the workpiece

bearing surface.

The mandrel can then be pushed

into the adaptor where the built-in

spring clip will hold it in place.

Store the mandrels in their positions

on the storage bracket when not in

use.

POSITIONING THE 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.

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.

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.

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.

WARNING: NEVER USE EXTENSIONS TO THE RAM PUMPING HANDLE
