Air Supply
Operating Procedure
Putting into Service
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 1/4 inch.

IMPORTANT
When placing Standard Nutserts, lubricate the drive screw of the tool every 25 placings. This is best
achieved by wiping the drive screw with a sponge soaked with STP Lubricant part number 07992-00013.
OPTION 1
•Ensure that the correct nose equipment is fitted.
•Connect the tool to the air supply.
•Place the insert into the prepared hole of the application.
•Locate the drive screw of the tool into the insert.
•Operate the lever. The drive screw will screw into and
collapse the insert, then automatically reverse out.
OPTION 2
•Ensure that the correct nose equipment is fitted.
•Connect the tool to the air supply.
•Screw the insert lip first onto the drive screw of the tool.
•With the insert on the tool, locate it into the prepared
hole of the application.
•Operate the lever. The drive screw will screw into and
collapse the insert, then automatically reverse out.

Clutch Adjustment
Accessories
Putting into Service
If you have ordered a complete tool the clutch will be set for the specified insert.
When purchased as a spare part, the clutch is supplied unset.
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.
For details on how to adjust the clutch refer to maintenance instructions referring to the clutch on page 15.
Two different accessories are available to make the connection to your air supply:

Nose Assemblies
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 10.
IMPORTANT
The air supply must be disconnected when fitting or removing nose assemblies unless specifically instructed
otherwise.
Before fitting the nose equipment, ensure the clutch on the tool is set to the correct torque for the insert being placed. (Torque values
are on page 6.)
•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.
•Screw adaptor 7into clutch housing of the base tool (left hand thread).
•Offer up the nose assembly to the adaptor. It will be necessary to rotate the drive screw by hand to line up the hexagon on the
drive shaft 6with the hexagonal hole in the front jaw of the base tool.
•Screw the nose housing 2onto the adaptor 7and tighten with a spanner (left hand thread).

The employer is responsible for ensuring that tool maintenance instructions are given to the appropriate
personnel. The operator should not be involved in maintenance or repair of the tool unless properly trained.
Regular servicing should be carried out and a comprehensive inspection performed annually or every 200000 cycles, whichever is
soonest.
•Daily, before use or when first putting the tool into service, pour a few drops of clean, light lubricating oil into the air inlet of the
tool if no lubricator is fitted on air supply. If the tool is in continuous use, the air hose should be disconnected from the main air
supply and the tool lubricated every two to three hours.
•Check for air leaks. If damaged, hoses and couplings should be replaced by new items.
•If there is no filter on the pressure regulator, bleed the air line to clear it of accumulated dirt or water before connecting the air
hose to the tool. If there is a filter fitted, drain it.
•Check that the nose assembly is correct.
•Inspect the drivescrew in the nose assembly for wear or damage. If there is any, renew.
•Fully dismantle and service the nose assembly (see instructions page 9).
•Lubricate the clutch spring with high pressure grease (eg. Shell Alvania EPI).
•Check the clutch torque setting (see clutch adjustment procedure page 15).
•Check for air leaks in the air supply hose and fittings.
