SAFETY PRECAUTIONS
• During assembly or if the press is moved, ALWAYS use a suitable crane or hoist,
do not manhandle.
• Ensure the press is located on firm level ground with adequate light.
• Before applying a load, ensure both 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.
• Keep warning decals legible and intact. Replacements may be obtained
from Clarke International Spare Parts Department.
• 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
Ensure the press and its components suffered no damage during transit.
Should any damage be apparent, please contact your CLARKE dealer
immediately.
IMPORTANT: Due to the weight of the press, we recommend that you get
assistance from another person during assembly.
1. With the main frame upright and adequately supported, bolt on the two
feet using the nuts and bolts supplied.
IMPORTANT: We strongly recommend that the press be firmly secured to a
firm and level floor using expansion bolts (not supplied).
2. Remove the plug on the front of the pump body 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.
5. Insert the two supporting pins into the lowest holes on the frame, one each
side.
6. With assistance place the bed on top of the two pins.
BED HEIGHT
Position the bed at the desired height, so as it will be as close as possible to the
ram when the workpiece is mounted.
IMPORTANT: Due to the weight of the bed, we recommend that you get
assistance from another person when adjusting the bed height.
1. Raise one side of the bed, and insert a supporting pin into the next locating
hole.
2. Repeat at the other end of the bed to level out the bed,
3. Repeat steps 1 and 2 until the bed is at the desired height, with the
supporting pins fully ‘home’.
CAUTION: THE BED HEIGHT SHOULD ONLY BE RAISED OR LOWERED 1
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

POSITIONING THE RAM
The ram can positioned as required
by sliding it along the top rail.
• Always position the ram directly
above the workpiece.
HYDRAULIC PUMP/RAM OPERATION
The pump is provided with two valves, operated by turning the respective
handwheel as shown.
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. Place the workpiece on the bed.
• It must be completely stable. you must use packing or shims where required.
‘Vee’ blocks and a supporting plate are supplied, which locate on the bed.
Place the workpiece on a combination of these 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 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. Turn the Handwheel B, clockwise
to move the ram quickly, and
Handwheel A, clockwise to lower
the ram.
3. Pump the handle to bring the ram
very lightly into contact with the
workpiece.
4. Manoeuvre the workpiece or slide
the ram so that the desired point
of contact is directly beneath the
centre of the ram.
5. When satisfied that the workpiece
is correctly lined up and is
completely stable in that position,
ensure the handwheel B, 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. 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 handwheel A, anticlockwise to
release ram pressure.
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 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 the
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.
• Check the hydraulic connections for leaks. Replace or properly repair any
damaged or leaking hydraulic components before using.
EVERY 6 MONTHS
• 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.
EVERY 2 YEARS
• Replace the hydraulic oil. This operation requires the dismantling of the
hydraulic system, for which you should consult your CLARKE dealer.
• If any rust is apparent it must be removed completely and reinspected.
