Nose assemblies are specifically designed for each size and type of insert. If you have purchased a complete tool, it will already be
fitted with the correct nose assembly for your insert.
It is essential that the correct nose assembly is fitted prior to operating the tool. By knowing your original complete tool part number
or the details of the insert to be placed, you will be able to order a new complete nose assembly using the selection table page 5.
FITTING INSTRUCTIONS

The air supply must be disconnected when fitting or removing nose assemblies unless specifically instructed otherwise.
