ASSEMBLY PROCEDURE
IMPORTANT: The press must be firmly secured to a firm and level floor using
expansion bolts (not supplied). Holes are provided in the feet 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 base supports to the
frame using the nuts, bolts and
washers.
2. Add the stay bars to each side
and bolt into place.
3. Using suitable lifting equipment if
required, lift the frame assembly
upright and manoeuvre it to its
intended location in the
workshop.
4. Bolt the hydraulic pump into
position on the side of the frame
using the fixing bolts and washers.
5. Fit the pressure gauge through the
frame and secure loosely with the
large nut supplied Remove any
protective bung from the gauge
before fitting.
We recommend sealing all threads
with PTFE tape where hydraulic oil is
to be contained. Take care not to let
any oil escape while connecting the
hoses.
6. Screw the block connector and
the connecting piece to the
pressure gauge inlet.
7. Bolt the block connector to the
back of the frame and connect
the pump hose to the block
connector as shown.
8. Connect the ram hose to the
block connector.
9. Bolt the foot pedal to the frame
using the long bolt, spacer tube,
nut and washers.
10. 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.
1. Insert the pump handle into the
actuating lever.
2. Open the release valve by turning
anti-clockwise.
3. Pump several full strokes to
eliminate any air bubbles from the
system. Use either the handle or
the foot pedal.
4. Close the release valve by turning
clockwise.
5. Top up the hydraulic oil to the
lower level of the filler plug with
CLARKE hydraulic oil, Part No.
3050830.
POSITIONING THE PRESSING BED
IMPORTANT: Due to the weight of the press bed, we recommend that you
get assistance from another person when adjusting the bed height.
1. Position the pressing bed 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 bed 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 required height, with the bed supporting pins
are secured using the spring clips.
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.
1. Place the workpiece on the bed. It must be completely stable and
supported by packing or shims where required. Pressing plates (bed blocks)
are supplied, which locate on the bed. Place the workpiece on these to
give it stability.
CAUTION: DO NOT POINT LOAD SUCH 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
clockwise until tightly closed.
3. Select either SLOW SPEED or FAST
SPEED using the knob on the side
of the pump cover.
NOTE: Fast speed allows faster
movement but greater effort
will be required.
4. Pump the handle or foot pedal to
bring the ram very lightly into
contact with the workpiece.
5. Manoeuvre the workpiece or loosen the bolts and slide the ram to one side
so that the desired point of contact is directly beneath the centre of the
ram.
6. When satisfied that the workpiece
is correctly aligned and is
completely stable in that position,
raise the protective screen into
position before starting any
pressing.
7. Slowly pump the handle or foot
pedal so that the ram begins to
exert pressure on the workpiece.
8. Continue to pump the handle and constantly monitor the process,
ensuring the ram and work remain completely in line and there is no risk of
slipping.
9. Observe the reading on the pressure gauge and take care not to exceed
the rated working pressure of the press.
NOTE: The scale from 30 metric tonnes upward is highlighted in red,
indicating pressure being applied above the rated maximum
working pressure.
10. When the pressing process is complete, turn the release valve
anticlockwise in small increments to release ram pressure and allow
removal of the workpiece and lower the protective screen.

and remove the oil filler
plug. Pump the handle a
couple of full strokes and
close the release valve.
Replace the filler plug.
Check oil level by
removing the filler plug
and topping up to the
correct level.
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.
If the press 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 to protect the surface of the moving parts.
PERIODICALLY
Check the press to make sure all bolts are tight and inspect for cracked welds,
bent, loose or missing parts.
Clean any foreign material from the ram carrier sliding plastic blocks. Keep the
protective screen clean at all times.
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 (P34-page 17) 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.
DISPOSAL OF UNWANTED MATERIALS
One of the most damaging sources of environmental pollution is oil products.
Never throw away used oil with domestic refuse or flush it down a sink or drain.
Collect any oil in a leak proof container and take it to your local waste
disposal site.
Should hydraulic components become completely unserviceable and require
disposal, draw off the oil into an approved container and dispose of the
product and the oil according to local regulations.
