The part number of the base tool remains the same whichever nose assembly, or nose tip is fitted. See the General Assembly
pages 22-24.
The nose tip part number relates to a specific fastener. If access to the application is
restricted, some extended nose tips are available. See table page 12.
This single nose assembly will allow placing of fasteners by simply selecting the appropriate nose tip from
the range of Type 1 Nose Tips. Other nose assemblies are available for applications with restricted access
and special fasteners. See table pages 11 and 12.

All tools are operated with compressed air at an optimum pressure of 5.5 bar. We recommend the use of pressure regulators and
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 effective working 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.

•Ensure that the correct nose assembly suitable for the fastener is fitted.
•Connect the tool to the air supply.
•Insert the fastener stem into the nose of the tool. If using a standard nose assembly, the fastener should remain held in by the
vacuum system.
•Bring the tool with the fastener to the application so that the protruding fastener enters squarely into the hole of the application.
•Fully actuate the trigger. The tool cycle will broach the fastener and with standard nose assemblies the broken stem will be
projected to the rear of the tool into the collector bottle.
Quarter turn to Assemble
or Remove
•A quarter turn rotation removes or replaces the collector bottle.

Collector Bottle is removed
•Ensure that the correct nose assembly is fitted, see pages 12 and 13.
•Connect the tool to the air supply.
•Push the Avtainer®or Maxlok®stem through the application hole.
•Place the collar on the stem (orientation as shown below).
•Keeping the head of the stem against the application, push the tool onto the protruding stem.
•Fully depress the trigger. One cycle will ensure that the collar is swaged into the lock grooves of the stem and that the stem
breaks at the breaker groove.
•Release the trigger. The tool completes its cycle by pushing itself off the collar and the spent stem will be pushed to the rear of
the tool on insertion of the next fastener.

IMPORTANT
Nose assemblies do NOT include nose tips. Nose tips must be ordered separately.
A tool must always be fitted with the correct nose assembly and nose tip for your fastener and must be ordered separately, refer to
the ‘NOSE TIPS’ tables on pages 10 to 13.
If your application presents no access restriction use a Type 1 nose tip. If you are placing Avtainer®a Type 5, Hemlok®and 1/4”
Interlock®a Type 6 must be used. Maxlok®requires a special nose assembly which does not make use of any nose tip, see pages
10 to 13.
Dimensions ‘A’ and ‘B’ will help you assess the suitability of a particular nose tip.
You should also check that the dimensions of the nose casing will not restrict access to your application. If access is restricted Type
2 nose tips with extra reach, are available for some fasteners. Refer to the table on page 12.
It is essential that a fastener-compatible nose assembly and nose tip are fitted prior to operating the tool (no nose tip with Maxlok®).
Fitting Instructions - All Nose Assemblies except Avtainer® and Maxlok®
