10. OPERATION INSTRUCTIONS
The tool is well assembled and tested before delivery; however, the necessary setting and testing are still strongly suggested
before operating tool. Carefully read this OPERATION INSTRUCTIONS 10.2 - 10.9 to check the setting of tool, follow the 10.8
OPERATION PROCEDURE to do the pilot test before operating tool.
The compressed air pressure should be in the suggested working range; tool’s working threaded mandrel size, nosepiece
size, rivet nut size and work piece’s hole diameter must be well matched, so that the pilot test can verify the fastening work
is firmed or not.

10.1 SETTING AND TESTING
This pneumatic-hydraulic rivet nut tool is operated with compressed air at an optimum air pressure of 6.5 bar or 95 psi.
This pneumatic-hydraulic rivet nut tool is recommended to connect with COMPRESSED AIR SUPPLY SYSTEM including
air compressor, main air supply line, air preparation unit (air filter, air pressure regulator with gauge, air lubricator) and air
hose. These should be fitted within 3 meters or 10 feet from air pressure regulator to the tool to ensure maximum tool life
and minimum tool maintenance.
The air pressure regulator is used to adjust the operating air pressure not to exceed the maximum operating air pressure
7.0 bar or 100 psi.
The air hose should resist a minimum 150% of maximum operating air pressure (7.0 bar or 100 psi) produced in the
COMPRESSED AIR SUPPLY SYSTEM, that is to resist the highest air pressure 10.5 bar or 150 psi. The air hose should be
oil resistant, and have an abrasion resistant exterior. The air hose must have a minimum inner diameter of 10 mm or 3/8” .
Be sure to expel the accumulated dirt and water from air pipeline before connecting air hose to the tool.
