Nose Assemblies; Nose Jaws - avdel Genesis 7537 Manual De Instrucciones

N o s e A s s e m b l i e s
On speed fastening tools such as 0753 MkII type, the nose equipment always consists of three elements: a nose jaw, a mandrel and a
mandrel follower spring. All three items are matched to the fastener being placed and to the hole size in the application.
To avoid complete dismantling of the tool it is essential to check the orientation of the cursor before fitting
It is essential that the correct nose equipment is fitted to the tool to ensure both effective placing of the
fastener and SAFE operation of the tool. READ THE SAFETY INSTRUCTIONS page 4 carefully.
To identify the correct combination of nose equipment to fit your tool first select a nose jaw by reading the section below then read the
mandrel section to select part numbers both for the mandrel itself and for the mandrel follower spring. Mandrels and mandrel follower
springs are illustrated on page 11.
To fit the nose equipment, follow the 'Loading the Tool' procedure page 10.

The wrong nose jaw could result in an incorrectly placed fastener or incorrect clench.
Nose Jaws can be categorised into 7 different basic shapes as illustrated opposite, even though internal dimensions will vary
according to the fastener it is intended for. Exact dimensions referring to the letters in the illustrations opposite are indicated in the
'Nose Jaw Selection Tables' on pages 14-15.
