INTRODUCTION
Thank you for purchasing this CLARKE 50 Tonne Hydraulic Press.
Before attempting to operate the press, it is essential that you read this manual
thoroughly and carefully follow all instructions given. In doing so you will ensure
the safety of yourself and that of others around you, and you can also look
forward to the press giving you long and satisfactory service.
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.
1. Due to the weight of the press, lifting equipment and the help of an
assistant will be required during installation. Fix the press to the floor using
suitable anchor bolts.
2. Before starting work, check for signs of cracked welds, loose or missing
bolts, damaged screen, or any other damage. Do not use if any of these
conditions exist. Have repairs made only by authorised service centre.
3. Before work, always ensure that hydraulic hoses and couplings are
completely sound.
4. NEVER tamper with the press components or modify them. The safety valve
is set and sealed at the factory; do not attempt to adjust the setting.
5. Use only the recommended hydraulic oil.
6. The components of this press are designed to withstand the rated load. Do
not substitute any other components or exceed the rated load of the press.
7. Before applying pressure, ensure the workpiece is firmly secure and stable.
8. ALWAYS clean up spills of hydraulic oil immediately as this can be
dangerous in a workshop environment.
9. Do not let any person who is unfamiliar with hydraulic presses use the press
unless they are under direct supervision.
10. Keep children and unauthorised personnel away from the work area.
11. ALWAYS position the (optional) safety screen directly front of the workpiece.
12. ALWAYS apply the load under the centre of the ram. Offset loads can
damage the ram and may cause the work piece to be ejected.
13. ALWAYS ensure the work piece is properly supported by the press bed.
14. When using accessories such as pressing plates, be certain they are
centered below the ram and are in full contact with the bed.
15. Parts being pressed may shatter or be ejected from the press. Always use
adequate guards and wear eye protection and protective clothing when
using this press.
16. Keep hands and fingers away from parts that may pinch or shift.
17. NEVER use extension tubes to increase the length of the pump handle or
foot pedal. Excessive effort can cause damage and/or accidents.
18. Wear ANSI approved impact safety goggles heavy duty work gloves.
19. Failure to heed these warnings may result in damage to the equipment, or
serious personal injury.
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.
• 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 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,
slide the protective screen (if
fitted) 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 pressing,
ensuring the ram and work remain completely in line with 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.
• The scale from 50 metric tonnes upward is highlighted in red, indicating
pressure is being applied above the rated maximum working pressure.
10. When the pressing task is complete, turn the release valve control knob
anticlockwise in small increments to release ram pressure and allow
removal of the workpiece and lower the protective screen.
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. Keep the protective screen (if
fitted) clean at all times.
Check the hydraulic connections for leaks. Replace or properly repair any
damaged or leaking hydraulic components before using. Note any loss of oil
and if oil is seen to become foul, replace using CLARKE hydraulic oil, Part No.
3050830.
If any rust is apparent on the structure 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.
When requesting spare parts, please quote the number on the diagrams/parts
lists on pages 14-18.
