SAFETY PRECAUTIONS

• During assembly or if the press is moved, ALWAYS use a lifting appliance ­crane or hoist etc., do not man handle.

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

• Before applying a load, be certain that all press bed support pins are fully
engaged, and the hydraulic ram is fully located into the ram mount. Ensure
also 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 extremely
dangerous in a workshop environment.

• Do not exceed the rated capacity.

• Do not allow any person, who is inexperienced in the use of hydraulic presses,
to use the machine unless they are under direct supervision.

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

• Never tamper with the machine. The safety valve is calibrated and sealed at
the factory, do not attempt to change these settings.

• 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 on the centre of ram plunger. Offset loads can
damagethe ram or ram mount and may cause 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 centres.

• Remove all loads from press bed before attempting to adjust bed height.
Beware of possible falling bed.

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

• When using accessories such as arbor plates, be certain they are centered
on press bed, 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 heavy protective clothing when operating this press.

• Keep hands and fingers out of the press and away from the parts that may
pinch and shift.

• It is the owners responsibility to keep warning decals legible and intact.
Replacements may be obtained from Clarke International Spare Parts Dep’t.

• 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

PARTS LIST - 15 & 25 TON

Ensure the press and its components suffered no damage during transit. Should
any damage be apparent, please contact your CLARKE dealer immediately.

1. With the main frame upright and adequately supported, considering its
weight, bolt on the two feet using the nuts and bolts supplied.

We strongly recommend that the press be firmly secured to a firm and level floor

2. Remove the plug on the front of the pump body - parts list item 43 (15/25 ton)
or 16 (50ton), and replace it with the vent plug supplied.

3. Remove the cap on top of the ram. Seal the thread with PTFE tape and screw
in the pressure gauge, ensuring it is tight.

4. Fit the pump handle into the actuating lever.

NOTE: Do not locate your press where it will be open to the elements, as it is
designed to operate at temperatures of between -10OC to 40OC. Severe weather
conditions will damage the hydraulic system.

Your Hydraulic Press is now ready for use.

HYDRAULIC PUMP/RAM OPERATION

The pump is provided with two valves, operated by turning the respective
handwheel as shown in Fig. 1.

Valve A is used for raising or lowering
the ram.

Turn the handwheel clockwise and
pump the handle to operate (or
lower) the ram. Turning the handwheel
anticlockwise releases the pressure
and the ram will rise.

Valve B is used to move the ram in fast
or slow mode.

Turn the handwheel clockwise and pump the handle to move the ram quickly to
the workpiece. Turning the handwheel anticlockwise and pumping the handle,
moves the ram at a slower rate.

OPERATION

1. Position the bed to the desired height, so as it will be as close as possible to the
ram when the workpiece is mounted.

WARNING:

NEVER use extensions to the ram pumping handle

Raise one side of the bed, and insert a pin into a locating hole directly
beneath the bed. Repeat the process at the other side, until the bed is level
and at the desired height, with the pins fully ‘home’.

The 50Ton version is provided with a winch with which to raise the bed. Simply turn the
handleto raise the bed to the appropriate height in order to insert the support pins.
Turn the handle to lower on to the pins, so they take the full weight.

2. The workpiece is placed on top of the bed, and must be completely stable.
to achieve this you must use packing or shims where required.

‘Vee’ blocks (and a special Plate with the 15 & 25ton) are supplied, which
locate on top of thebed. Either, or a combination of these, may be used and
on to which the workpiece may be placed, to give it stability. 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.

NOTE: Any packing pieces or shims used, MUST be capable of withstanding the
extreme pressure that will be brought to bear, and MUST be of sufficient size with
sufficient surface contact, so as to avoid the possibility of slipping or springing
taking place. Mating surfaces MUST be horizontal so that the force being exerted
will be vertical and NOT at an angle.

3. Turn the Handwheel B, Fig 3, clockwise to move the ram quickly, and
Handwheel A, Fig 3, clockwise to lower the ram. Pump the handle to bring the
ram very lightly into contact with the workpiece.

Manoeuvre the workpiece so that the desired point of
contact is directly beneath the centre of the ram.

4. When satisfied that the workpiece is correctly lined
up and is completely stable in that position,
ensure the handwheel B, Fig. 3 is turned
ANTICLOCKWISE, and 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 of
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.

5. When the process is complete, turn the handwheel A, Fig 3,
anticlockwise to release ram pressure

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 may require
specialised knowledge and facilities. It is recommended that a thorough annual
inspection of the press be made and that any defective parts, decals or warning
labels 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 necessary repairs
are made.

• Periodically check the press frame to make sure all bolts are tight and inspect
for cracked welds, bent, loose or missing parts.

• Periodically check the hydraulic connections for possible leaks. Replace or
properly repair damaged or leaking hydraulic components before using.

• Periodically apply a light smear of oil to the moving parts and the bed support
pins.

• At 6 monthly intervals, check the hydraulic pump oil level, by removing the
plug from the front of the unit. Oil should be level with the bottom of the hole.
If necessary top up with CLARKE Hydraulic Oil, Part No. 3050830 only.

This operation is carried out with the ram fully retracted.

• Replace the Hydraulic oil every TWO years. This operation requires the
dismantling of the hydraulic system, for which you should consult your CLARKE
dealer.

• The 50 Ton model requires the winch cable to be inspected every 6 months
for wear. Always wear a good pair of industrial gloves when handling wire
rope as damaged strands could cause severe injury.
If any rust is apparent it must be removed completely and reinspected. Renew
the rope if strands are broken or rusted through.

Apply grease to the rope and oil the moving parts of the winch.
