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,
Vibration and Principal of Operation
information shown on page 4.
2. Visually 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.
