Tool operation (Fig. 2)
The tool is operated by means of a rotary hand-grip. To cut, crush or
pull, turn the hand-grip anti-clockwise. To open the blades, or use the
tool for spreading, turn the hand-grip clockwise.
To allow connection to a pump, the tool is equipped with two 0.4 m
(15,7 in) long hoses, one with a male quick coupling and the other
with a female quick coupling. Both are fi tted with dust caps. The
female coupling also has a locking ring. The tool pressure hose has
the word "PRESSURE" marked on the end of the hose.

Safety features

A dead man's handle incorporated in the hand-grip interrupts
operation of the tool as soon as you release the hand-grip.
A built-in safety valve protects the tool if the return hose is not
corrected properly. If the safety valve has tripped or the return hose
is not properly connected, a small amount of oil may leak out of the
front of the control valve.
The hold function ensures that the tool maintains pressure against
the applied load even if the hoses are disconnected. Twisting the
hand-grip has no effect on this hold function as long as the tool
hoses are disconnected.
Connection/Disconnection (Fig. 3)
To connect the tool to a pump, connect the tool pressure hose to
the pump pressure hose. Both hose ends are labelled with the word
"PRESSURE". The tool can be connected directly to the pump or via a
separate hose reel. Similarly, the tool return hose is connected to the
pump return hose, directly or via a separate hose reel.
The male and female couplings can only be connected when the
hoses are depressurised and the locking ring on the female coupling
has been screwed back.

After connection, the locking ring on the female coupling must be
screwed over the male coupling. This prevents accidental disconnection
and shows that the couplings are properly connected.
The male and female dust caps should now be joined together
as shown in (Fig. 4). This prevents the dust caps from becoming
contaminated.
To disconnect the tool, simply reverse the sequence. NOTE, the
hoses must be depressurised before being disconnected. After
disconnection, fi t the respective dust caps to the couplings to
prevent contamination of the couplings.
Practical work
Always try to keep the tool at right angles to the object. If the tool
begins to twist - stop work and get a new grip.
Once the tool has started to twist the situation will never improve,
but only get worse.
When cutting has reached the point where the tips of the shears
meet, stop and check the following:
- That the tips of the shears have not become crossed so that
they meet on the wrong side, as shown in fi g. 5, A.
- That the tips of the shears are not being forced apart
sideways, as shown in fi g. 5, B.
- If the tips of the shears are correctly positioned as shown in
fi g. 5, C and the tool is at right angles to the object, continue
cutting.
As cutting proceeds make sure the shears do not move apart.
When cutting closed sections, where you cannot see the tips of
shears, you must take great care, especially until you are sure that
the tips of the shears have met correctly.
When the work is complete
Close the blades to the halfway position, so they are not wide open
and not closed. Store the tool like this.
Safety
• Always use personal safety equipment, full-length overalls,
a helmet with visor or safety goggles, gloves, etc.
• Consider the risk of sparks if electricity cables are
damaged or cut. Before you start work, always check that
the object you intend to work on is not connected to any
power supply.
• Take care when cutting springs or spring mountings.
These are often under tension and can cause injury when
released.
Maintenance
To ensure reliable operation of the tool it is important to carry
out regular maintenance. Go through each of the check points
whenever you fi nish using the tool.
• Clean the tool.
• Check that the tips and blades are not damaged. If the tips
or blades are chipped, replace them! The tips and blades will
still work even if they are chipped, but the resulting stress
concentration could cause the tip or blade to break next time
the tool is used.
