• 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 an 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.
• DO NOT use extension tubes on the pump handle. Excessive effort can cause
damage and/or accidents.
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.
TOOLS REQUIRED
• Spanners to suit M6, M8 and M10 nuts/bolts, or an adjustable wrench.
• PTFE tape
ACCESSORIES
A mandrel set (including storage bracket and pressure plate) is not supplied
with the press but is available from your dealer as Clarke part no 7615060.

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.
9. 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.
10. Screw the pump handle into the pump actuating
lever.
11. 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.
• If empty, the total capacity is 630ml.
12. If obtained, bolt the mandrel storage
bracket to the side of the frame using the
bolts supplied.
13. Store the mandrels including the adaptor,
in their positions on the bracket.
14. 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
WARNING: FAILURE TO HEED THE WARNINGS ON PAGE 3 MAY RESULT IN
DAMAGE TO THE EQUIPMENT, OR FAILURE RESULTING IN PROPERTY
DAMAGE OR PERSONAL INJURY.
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.
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.
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 and pressure gauge,
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.
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.
• 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
