REPLACEMENT OF THE CUTTING BLADE
First withdraw the anvil as described above.
Pump out the main ram until the blade retaining pins 030636 can be seen in the opening of the
cutter body.
The three pins are ¼” (6.35mm) diameter and they should be knocked out enough to release the
blade.

REMOVAL OF THE MAIN CYLINDER
If it is necessary to renew the hydraulic seals, the cylinder must be removed from the tool. As an
aid to this, 2 off tapped holes are provided in the cylinder end face. These are M10 x12 deep on
130mm centres.
First, remove the anvil as described above, pump out the ram and remove the blade.
To use the holes in the top of the cylinder first remove the coupling, then the blanking screws
035050 and fasten a piece of flat bar, typically 30x10mm section and 900mm long centrally to
the top of the cylinder. This can be used to loosen or re-tighten the cylinder. Do not use Stilsons
to remove the cylinder as damage will occur.
Unscrew the cylinder 728075 and remove from the assembly, it will come free but still attached
will be the ram 764113 and bearing ring 774032.
