In this manual particular references are made regarding aspects of safety and the notes below
are intended as a summary to highlight the main areas for your attention.
The machine should be positioned so that the operator has sufficient room to work having
regard for the long lengths of material which may be punched or cropped. Electrical supply
should be by overhead cable to avoid possible damage.
It should be considered if additional equipment will be required to safely handle long or heavy
items being processed.
Any person who will use the machine should be given adequate instruction on the operation
and safety aspects of the machine. Extra copies of this manual are available from the
manufacturer.
In addition it should be established which persons shall be responsible for the changing and
setting of tools and blades and these persons given a more detailed instruction.
Mubea Systeme machines are supplied complete with various guards and barriers as standard
equipment which provide a generally accepted level of guarding when the machine is used for
the purpose for which it was designed.
1. The main areas of deviation from design criteria would probably be:
2. The use of materials other than mild steel (65.000lbs.)
3. The incorrect use of material hold-downs
4. The punching, cropping or notching of small items
(as this would encourage the operator place fingers or hands into danger area).
If at any time additional tooling or equipment is fitted to the machine the question of adequate
guarding must be reviewed and the advice of the manufacturer sought if necessary.
All maintenance should be carried out by suitably qualified personnel and particular attention
must be paid to the correct setting and alignment of punches and dies, blades and other tools.

The shearing unit is fitted with a simple robust hold-down which is adjustable to any thickness
of material within the cutting capacity of the machine. A shear feed table with adjustable
guides is fitted to allow the accurate feeding of materials. The guide can be adjusted to allow
mitre cutting up to 45 degrees for flat bars or to trim the flanges of angle sections previously
cut at the angle cutting station.

This station provides large capacity angle cutting at 90 degrees and lighter angle cutting at 45
degrees. Angles between 45 and 90 degrees can be achieved by first cutting at 90 degrees and
then flange trimming to the required angle in the shearing station.
The hold-down supports the material thus ensuring a true cut.

3.6.1 System Pressure
To check any operational loadings, a pressure gauge can be fitted at the manifold position.
The max. system pressure has been set at the works to 234 bar (3500 P. S. I.) which is below
the max. continuous working pressure of the pump, thereby giving increased reliability.
3.6.2 Cleaning
On arrival, all anti-corrosion lacquer should be removed from the machined bright parts with
petroleum solvent. When the machine is operational, all visible working parts should be
regularly cleaned of foreign matter, thus preventing excessive wear and possible failure.
3.6.3 Lifting
The machine is supplied with a lifting eye, mounted on top of the machine. All lifting and
manoeuvring should be carried out using this eye along with a suitably rated chain or sling.
The eye can be removed if desired after final siting of the machine but hole should be blanked
off.
DO NOT USE SLINGS UNDER MACHINE!
3.6.4 Installing
Locate the machine on a solid foundation allowing sufficient area all round for easy working
and maintenance. The machine may be used free standing, but bolting to the foundation is
recommended. With the machine mounted directly on the floor - this gives a comfortable
working height.
3.6.5 Electrical Supply
Input wires should arrive at the machine via suitably protected underground supply directly
into the electrics box in the base of the machine. As an alternative by overhead supply to the
top of the machine and routed inside the top guard and hydraulic pipe trunking to the electrics
box. A 30 amp isolating switch, fuse and appropriate cable should be used for mains supply
connection. The circuit provides protection against sustained over-load and phase failure.
Should the machine cut out during an operation or whilst running, the cause of the problem
should be investigated to prevent re-occurrence.
IMPORTANT
Motor rotation MUST be as arrow on motor fan end cover!
This machine will not operate if the motor is running in the wrong direction. It must be
stressed however that the motor must not be allowed to run in the wrong direction for
more than a few seconds, as this will cause seizure of the pump. To check motor
direction start and stop motor with foot on footswitch if machine does not operate
reverse two of the incoming 3 phase connections.

•All adjustments, setting, change of tooling and maintenance must be carried out by a
suitable qualified engineer in accordance with the manufacturers instructions.
•Remove off-cuts, slugs and any other waste from around the machine before leaving the
work station.
•The operator should check all tooling is in good condition before operating machine.
•All stations should be checked for obstructions.
•Heavy work should be supported by a sound work steady.
•The machine should never be left running while unattended.
•When leaving, the machine MUST be switched off.

In the event of an accidental overload to the hydraulic circuit, the oil will be diverted direct
back to the tank via a relief valve, until the overload condition is removed.

Any point of the machine painted RED should be treated as a danger area. Operators should
be instructed not to extend any finger or limbs into or beyond the vicinity of the warning
labels. Any guards or hold downs removed for maintenance or adjustments MUST be replaced
before the machine is put back in service.
