Principle of Operation
When the Trigger 23 is depressed the Throttle Valve 28 moves to down position,
pressurized air is directed to underneath the Air Piston 58 , causing the Piston and Piston
Rod 49 to move upward. The air above the Piston is exhausted from the tool. As the
Piston Rod 49 moves upward, a column of hydraulic oil is forced into the head of the tool
in front of the Pull Piston 15 , which moves back. The attached Nose Assembly moves
with the Pull Piston to start fastener installation. When fastener installation is completed,
the Trigger 23 is released and the Spring 30 causes the Throttle Valve 28 to return to its
up position. Pressure from Spring 18 returns the Pull and Air Pistons to their original
positions. The air from below the Air Piston is exhausted from the the tool. The Shock
Absorber 68 impedes oil flow at pinbreak helping prevent tool recoil.
Preparation for Use
The air supply connector has a male pipe thread to accept an air hose fitting. Quick
disconnect fitings and a 6.4 mm (1/4") inside diameter air hose are recommended. An air
supply of 6.2 to 6.9 bar (90-100 psi) capable of delivering 566 l/min (20 CFM) is
recomended. The air supply should be equipped with a fifter-regulator-lubricator unit.
1. Read and ensure that you understand
the Safety Guidelines at the front of this
manual. Also, read and ensure that you
understand the Specification, Noise,
V ibration and Principal of Operation
information shown on page 4.
2. V isually check the Installation Tool for
damage and leakage, replace or rectify
as necessary.
3. Ensure the Deflector is in place on
the Installation Tool and that it is not
damaged. Replace with a new Deflector
if necessary.

EJECT WITH SPEED AND FORCE. BE
SURE THE PINTAIL DEFLECTOR IS
DIRECTED SAFELY.
5. Insert the fastener into the prepared
hole.
6. Hold the Installation Tool firmly by the
handle with the hand in a position that
enables finger operation of the Air Trigger.
If necessary, use the other hand to
support the Installation Tool by holding the
Air Cylinder of the tool. D O N O T place the
hand arround the Nose Assembly.Ifa
Pintail Collector Bottle or Bag is not fitted
to the Installation Tool, ensure the
Deflector is positioned safely so that the
ejected Pintails will not cause injury to
yourself or fellow workers. 8
7. Place the Nose Assembly over the
Pintail of the fastener and gently push
forward until the Anvil of the Nose
Assembly is in contact with the fastener.
Operate the Air Trigger.
8. When the fastener Pintail fractures, (at
the same time the Installation Tool may be
released from the installed fastener),
release the Trigger. The Installation Tool
Piston and inner components of the Nose
Assembly will now return to the fully
forward position, (return stroke), ready to
install the next fastener; this normally
takes about one second.
To avoid damage to the Nose Assembly,
D O NOT place the Nose Assembly over
the Pintail of a fastener until the return
stroke is completed.
9. If a Pintail Collector Bottle or Bag is
fitted to the Installation Tool, empty at
regular intervals using authorised disposal
proceedures.
Failure to do this will could result in
Pintails causing a blockage in the
Installation Tool and/or Nose Assembly
resulting in serious damage to
components.
10. In the event of a mains air supply
failure coincident with a fastener retained
in the Nose Assembly of the Installation
Tool, the Installation Tool and Nose
Assembly must be placed in a safe
location to prevent inadvertent operation
of the Trigger once power is restored.
