Bush stops are fitted to reduce the stroke length of the tool thus the tool cycle time and shock loads. Minimising shock loads
will increase the efficiency of the tool and will prolong the life of the mandrel.
Each tool is supplied with three bush stops already fitted. It may be necessary to remove one or more of these to match the length of
the fasteners to be placed so that when in the fully back position, the mandrel head lies just inside the nose jaws.
Use the table below to ascertain the number of bush stops recommended for your fastener. First find the relevant diameter and within
that section select the correct length code. These two digits are the last two of the fastener part number. Read the corresponding number
of bush stops in the line below.

Before checking that the mandrel head retracts to the correct position after a fastener has been placed, you will need to check the
cursor orientation and load the tool with fasteners.
C U R S O R
While the cursor will be fitted the correct way round when the tool is supplied, we recommend that you check its orientation before fitting
the nose equipment. The sprung loaded, slightly concave, end of the cursor should point towards the front of the tool as shown in the
illustration below.
When fitted the correct way round, the cursor will easily slide out of the barrel when a mandrel is pushed into its centre then pulled
back.
