•
Lightly coat the jaws with Moly Lithium grease.
•
Assemble Spring Guides 4 and Spring 5 and stand on end on a flat even surface.
•
Balance the three Chuck Jaws 3 on the upper Spring Guide 4 (using a spent pintail to aid positioning if necessary).
•
Carefully lower Chuck Collet 2 over the assembled components.
•
Screw the assembled chuck collet onto the Offset Spindle
18
on 07200 tool or Extension
83
on 07201 tool and tighten with a spanner.
•
Push the Anvil 1 over the Chuck Collet, lining up the bayonet with the matching slots of the offset adaptor assembly or straight adaptor
assembly.
•
Nose assemblies should be serviced at weekly intervals.
•
Remove the complete nose assembly using the reverse procedure to the ‘Fitting Instructions’.
•
Clean and inspect components, any worn or damaged part should be replaced by a new part.
•
Particularly check wear on jaws.
•
Ensure spring and spring guides (if fitted) are not worn or distorted.
•
Assemble according to fitting instructions.
•
Before placing ‘Avdelok
®
’ Pins ensure that the correct nose assembly is fitted to the tool.
•
To fit nose assemblies to the tool it is first necessary to screw the Chuck Collet 2 complete, on to the offset spindle
18
.
•
The Anvil 1 is then pushed on to the Offset Adaptor
16
ensuring that the lugs on the anvil enter the slots on the adaptor and then
turned through 90°. This ensures that Latch
23
positively holds swaging anvil in position and prevents inadvertent removal from the
tool.
•
To remove the swaging Anvil 1 the Latch
23
is held back and the anvil turned until the lugs appear in the slots on the adaptor, The
anvil can then be pulled off.
•
The collet assembly is removed by unscrewing it from the Offset Spindle
18
. Care should be taken to keep the nose of the gun
pointing downwards to maintain the correct position of the loose parts inside the collet.
•
It is important that when the collet is replaced it is firmly tightened up to the shoulder on the spindle.
