SAFETY PRECAUTIONS

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

assistant, do not manhandle single-handedly.

• Always bolt the press down to a suitably strong bench.

• Ensure the press is located on a strong bench with adequate light.

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

• Ensure that hydraulic hoses and couplings are completely sound.

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

• Always clean spills of hydraulic oil immediately as this can be dangerous in a

workshop environment.

• Do not exceed the rated capacity of the press.

• Do not allow any person who is inexperienced in the use of hydraulic presses,

to use the press unless they are under direct supervision.

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

• 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.

INVENTORY

ASSEMBLY

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

that you get assistance during installation.

IMPORTANT: We strongly recommend that the press be firmly secured to a

firm and level bench using suitable bolts (not supplied).

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

Severe weather conditions will damage the hydraulic components.

1. Attach the feet to the frame,

using the nuts, bolts and washers.

2. With the help of an assistant, lift

the frame assembly upright and

manoeuvre it to its intended

location on the workbench.

3. Insert the ram through the hole in

the base plate and secure in

position using the locking collar.

4. Unfasten the protective end cap

and screw the hose to 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.

5. 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.

6. Attach the pump assembly to the

frame using the fixing bolts and

washers. Fit one bolt first to bear

the weight and use the

adjustment provided by the

upper bolt.

• The pump can be installed on

either side of the frame but will

usually be assembled for a right-

handed press operator.

7. Screw the pump handle into the

pump actuating lever.

8. Unscrew the filler plug and

withdraw the dipstick. Check that

the pump is filled with hydraulic oil

up to the level shown on the

dipstick.

9. If obtained, bolt the mandrel

storage bracket to the side of the

frame using the bolts supplied.

10. Store the mandrels (if obtained)

including the adaptor, in their

positions on the bracket.

11. Insert the bed support pins into

the holes in the columns at the

required position. Then set the

bed frame in position on the pins.

HYDRAULIC PUMP/RAM OPERATION

1. Before using the press, purge any

air from the system by opening

the release valve by turning it anti-

clockwise and pumping several

full strokes to eliminate any air

bubbles. Tight the release valve

before continuing.

2. Check all parts are secure and

correctly aligned before using the

press.

The press is now ready for use.

POSITIONING THE BED

1. Position the bed at the desired height, so it will be as close as possible to

the ram when the workpiece is mounted on it.

FITTING THE MANDRELS OR PRESSURE CAP

Mandrels are available as an

adaptor kit, any of which may be

connected to the end of the ram

using the adaptor.

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.

If one of the mandrels 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.

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 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. ‘Heel’ blocks (arbor 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 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.

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.

• 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 filler plug at the end of the unit.

Oil should be level with the mark on the dipstick. 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.

DE-COMMISSIONING THE PRODUCT
