Item
Procedure
Check the condition of the anvil
As described in section 9.3
Check the condition of the blade
As described in section 9.4
Before use of the tool, ensure that all operators are at a safe distance from the cutter, and that any
guarding or safety features are installed and operational.
Check that the hydraulic supply is set to an appropriate level for operation as stated in section 3.2.
8.2 Deploying the Tool
Begin the operation with the anvil fully retracted. To achieve this, pressurise the ‘Anvil Out’ port on
the HCV270 auxiliary cylinder.
Place the cutter over the workpiece. Ensure that the workpiece is fully inserted into the mouth of the
tool so that there is no risk of the anvil fouling against it as it is closed.
Close the anvil over the workpiece by pressurising the ‘Anvil In’ port on the HCV270 auxiliary
cylinder. Ensure that the ‘Anvil Out’ port is open to tank.
Fully inspect the tool to ensure the anvil is fully closed before continuing.

9Maintenance
It is unlikely that service would be required on the hydraulic piston of the tool under normal
circumstances, but a seal spares kit is available (995288) and it is recommended to stock this at all
times.
The only parts that would need intermittent replacement would be the anvil and blade depending on
the frequency of use, materials being cut and the corrosive conditions present during operation.
IMPORTANT - Replacement parts must always be sourced from Allspeeds Ltd. The use of unofficial
components will invalidate the warranty and may lead to tool damage or system failure.
9.1 Maintenance Notes
IMPORTANT –This cutter should only be serviced by qualified personnel. If in any doubt please
contact Allspeeds Ltd or a distributor.
Most maintenance task can be carried out with standard tools.
All servicing operations should be carried out in a clean environment to prevent contamination of the
oil and mating components.
Care should be taken with all mating areas, including threads and sealing faces, as any damage or
abrasive contamination could cause galling or seizing on re-assembly. Please note a suitable anti-
galling paste should be used (we recommend Swagelok Silver Goop) on all stainless steel threads.
The main cylinder (728075) is a pressure vessel and should not be drilled, machined, mutilated or
damaged in any way for mounting purposes or to assist in its removal for servicing, any warranty
could be invalidated by such actions.
The use of a Stilson wrench to remove the cylinder is not recommended as damage will occur.
Before carrying out any maintenance tasks ensure that the equipment is fully isolated and that there
is no residual pressure in the system.

9.3 Remove & Replace Anvil
IMPORTANT –The anvil may have sharp edges and imbedded material left behind from cutting
operations. Wear suitable gloves when handling the anvil.
IMPORTANT –Ensure that the hydraulic supply is isolated before proceeding.
IMPORTANT - Replacement parts must always be sourced from Allspeeds Ltd. The use of unofficial
components will invalidate the warranty and may lead to tool damage or system failure.
Begin the operation with the anvil fully retracted. To achieve this, pressurise the ‘Anvil Out’ port on
the HCV270 auxiliary cylinder.
Loosen the 8 off M6 screws (035079) holding pivot pin housings (749045A & B).
Loosen the M6 retaining screw (035073).
Figure 6 –Anvil Replacement
Withdraw the pivot pin (761267) far enough to release the lever arm. (There is an M6 tapped hole in
the end of the pivot pin to assist in withdrawing)
The lever arm can now be moved upwards to separate it from the anvil (SSC6488). The anvil may
now be slid out from the guide bush. Re-assembly is the reverse of the above process.
IMPORTANT –Mass of anvil (SSC6488) is 17.7kg. Ensure a safe system of work at all times.

Rev 9 Issue 2. Date: 25/08/2021
9.4 Remove & Replace Blade
IMPORTANT - The cutting edge may be sharp following tool operation, extreme caution and care
should be taken when checking it. Wear suitable gloves when handling the blade.
IMPORTANT - Ensure that the hydraulic supply is isolated before proceeding.
IMPORTANT - Replacement parts must always be sourced from Allspeeds Ltd. The use of unofficial
components will invalidate the warranty and may lead to tool damage or system failure.
The blade edge should be regularly checked to ensure that it is in good condition. This would be a
consistent blade edge with no chips or deformations noted along the entire cutting edge.
For safety we recommend that this operation is performed with the tool led down.
Begin with the anvil removed as described in section 9.3. The main cylinder should be in its fully
extended position. To extend the blade, pressurise the ‘Blade Down’ port on the HCV270 main
cylinder whilst ensuring that the ‘Blade Up’ port is open to tank
Remove the 3 off blade retaining pins (030636) using a suitably sized drift. Once blade retaining pins
are removed the blade is free to slide in the tool, care must be taken to prevent the blade from
falling or causing injury to operator.
IMPORTANT –Mass of blade (705050C) is 13kg. Ensure a safe system of work at all times.
Figure 7 –Blade Removal
Blade replacement is the reverse of the disassembly procedure.

9.5 Seal Detail
IMPORTANT –Ensure that the hydraulic supply is isolated before proceeding.
IMPORTANT - Replacement parts must always be sourced from Allspeeds Ltd. The use of unofficial
components will invalidate the warranty and may lead to tool damage or system failure.
IMPORTANT –Changing the seals will likely result in oil spills. Hydraulic oil spills present slip hazards.
Ensure a safe system of work at all times.
If it is necessary to inspect or 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 x 12mm
deep on 130mm PCD. Never use Stilsons or pipe clamps on the cylinder as damage may occur. If in
doubt contact Allspeeds for advice.
A cylinder assembly tool is available if required from Allspeeds (SK4377A).
Begin operation with the blade removed. See section 9.4 for this procedure.
Firstly, remove the coupling, hose and blanking plugs (035256) from the top of the tool and attach
the cylinder assembly tool (SK4377A). This can be used to loosen or re-tighten the cylinder.
IMPORTANT –Mass of Cylinder (728075) is 55.5kg and Ram (764113) is 26.7kg. Ensure a safe system
of work at all times.
Unscrew the cylinder and remove from the assembly. Use M10 holes to facilitate safe lifting. Care
should be taken as any contained oil within the cylinder will now be free to spill in the work area. The
cylinder will come free but seal stiction may mean that the ram comes also. If this happens, carefully
lay the cylinder assembly down in a safe location, connect a handpump or other hydraulic supply to
the cylinder and pump the ram out of the cylinder. Again, care should be taken as any contained oil
within the cylinder will now be free to spill in the work area.

The ram is fitted with relief valve plug assembly (991015) which also contains seals. To remove this,
locate off the two M8 x 12mm deep holes and unscrew the plug. The two relief valves have been
carefully set to operate at a set pressure and care should be taken not to disturb the settings during
removal. Remove these parts with a 17mm socket and 5mm hex bit.
With these parts now separate and the bearing ring (774032) now accessible, all main seals can be
seen and replaced.
