3. ESSENTIAL SAFETY REQUIREMENTS
In the event of the improper working of the machine or one of the connected elements, immediately halt all operation, depressurise the system and resolve
the problem.
Before beginning operation, make sure that the danger zone is unoccupied.
Always use the tools in well-lit areas.
Regardless of whether the cutting tool has a built-in or separate pump, try to establish the most convenient and stable working method for both the tool and
the operator.
In the case of tools with a separate pump, the hose enables the operator to move further away from the danger zone, while in the case of tools with built-in
pumps, if possible, a guard should be positioned between the work piece and the operator.
Do not expose tools to intense heat sources, such as welding equipment, for example.
Depressurise and disconnect the tools before carrying out any maintenance operations
In the case of tools with separate pumps, make sure all the quick plugs are completely clean before connecting.
Make sure that the hydraulic hoses are neither twisted nor unduly tensed.
When working with an electric pump, make sure that the valve is set to its neutral position before connecting the tool.
When working with cable cutters, fraying may occur during the cutting operation. To avoid this, clamp the cable to either end of the cutting blade with tape,
wire or even a bushing.
Clean the quick plugs thoroughly before connecting.
In all cases, the operator should be thoroughly trained in the operation of the tool and should act in accordance with the logical safety criteria associated
with the use of high-pressure equipment.

1- Hold the tool by the thick handle and with the tool in an upright position
(head facing up.
1- Connect the hose’s female quick plug to the tool’s male plug. Make sure
the connection is secure.
2- Pump the lever to check that the blade moves forward.
2- Read and follow the pump instructions.
3- Make sure the deformation zone is free from obstruction, and then continue
pumping until the blade reaches the end of its travel. At this point the lever will
become stiffer and harder to move.
3- Remove the pin and open the tool head.
4-Continue pumping until the safety valve is activated. Check for oil leaks.
4- When using electric or air-based pumps, the application is automated. In
such cases, the operator should be specially trained, in order to avoid the
possibility of involuntary actions.
5- Press the unload button and check that the blade returns to its initial
position.
6- Repeat this operation as many times as necessary in order to become
familiar with the operation of the tool.
7- Place the tool in position of work supporting the flat part on the bridle.
8- Look for the position in that the blade affects one of the faces of the hexagon
and pump until the blade between in contact with the nut.
9- Continue pumping until deforming the nut sufficient so that the takeoff of
pin.
10- Unscrew completely the nut with the help of a key.
5. MAINTENANCE
After use, the tool should be cleaned and the area where the blade comes into contact with the heads oiled.
In the event of oil leaks, disassemble the tool and change the seals. The individual blueprint provided for each tool specifies its components and codes.
During this operation, check the condition of the inside of the cylinder. If scratches or snags are detected, then a more thorough repair procedure will be
required. We recommend that this be carried out
by specialist personnel
.
In the event of improper functioning in the models with built-in pumps, we recommend that you send the tool to an authorised technical service for
inspection and repair.
CHANGING THE BLADE.
Model CN0024: Release two Allen M5x15 (51) screws, remove the blade and replace it with a new one and attach it by tightening the screw (22) once again.
Model CN0324: Release the pin (5), unscrew the head (3) and remove the blade using the screw (17).
Models CN0224, CN0233, CN0152 y CN0180: Release the pin (14) and remove the piston with the pump until the screw (13) its above the hole. Release the
screw (13) and remove the blade by the head, replace it, and fix it with the screw (13).Retract the piston and thread the pin (14).
