A I R S U P P L Y
All tools are operated with compressed air at an optimum pressure of 5.5 bar. We recommend the use of pressure regulators and
automatic oiling/filtering systems on the main air supply. These should be fitted within 3 metres of the tool (see diagram below) to ensure
maximum tool life and minimum tool maintenance.
Air supply hoses should have a minimum working effective pressure rating of 150% of the maximum pressure produced in the system
or 10 bar, whichever is the highest. Air hoses should be oil resistant, have an abrasion resistant exterior and should be armoured where
operating conditions may result in hoses being damaged. All air hoses MUST have a minimum bore diameter of 6.4 millimetres or

Correct clutch setting is necessary to ensure optimum deformation of the insert. If the deformation is insufficient (clutch torque too low)
the insert will rotate in the application. If the deformation is excessive (clutch torque too high), thread distortion will occur and extensive
wear on the drivescrew may lead to fracture.
I M P O R T A N T
The air supply to the tool must be disconnected when adjusting the torque of the clutch
Slide round the cover of the clutch housing (item 70 page 15) until you can see the serrations of the adjustment nut of the clutch
(item 10 page 15).
Using clutch adjuster key 74 supplied with the tool, turn the adjustment nut clockwise to decrease the torque or anti-clockwise to
increase the torque.
Turn the key one full turn at a time and test the tool having rotated the clutch housing cover back in place. Repeat as required.
After dismantling the clutch, we suggest that you set the torque to its minimum by turning the key fully clockwise then adjust by turning
the key anti-clockwise two turns at a time until the correct torque is acheived.
Two different accessories are available to make the connection to your air supply:

Nose assemblies are specifically designed for each size and type of insert used with the 07552 type of tooling. 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 4.
FITTING INSTRUCTIONS
I M P O R T A N T
The air supply must be disconnected when fitting or removing nose assemblies unless specifically instructed otherwise.
Where applicable, insert sleeve 8and thrust spring 9into nose housing 2.
Coat thrust washers 3and thrust bearing 4with high pressure grease (eg. Shell Alvania E.P.I.) and locate them in the order shown below into
the nose housing 2.
Where applicable, fit spacer 5through thrust washers and thrust bearings.
Insert drive screw 1through the above assembly.
Fit drive shaft 6into the hexagon hole in the drive screw head.
Insert stop 11 and spring 10 into the front of the base tool.
