Operating instructions

AIR SYSTEM

l

  The combination brad nailer / stapler is designed to operate on clean, dry, compressed 

air, regulated at 60-100 psi. The preferred system would include a filter (E), a pressure 

regulator (F) with a gauge (G), and an automatic oiler (H) located downstream from the 

main air supply (I), as close to the tool (A) as possible (within 15 feet is ideal). Do not use 

bottled air or gases. Please see figure below:

l

  All compressed air contains moisture and other contaminants that can harm the internal 

components of the tool. An air line filter (E) will remove most of these and significantly 

prolong the life of the tool. Ensure the in-line oiler (H) has sufficient oil. If an in-line oiler is 

not available, place 2 drops of oil into the tool’s air inlet at the beginning of each workday. 

More than this will be expelled from the tool’s exhaust during firing.

l

  Air Fitting: The nailer (A) should be equipped with a 1/4” NPT male plug (B) to fit a ‘quick 

connector’ coupling (C). To prevent accidental cycling even though disconnected, the 

tool must always be connected to the air supply in such a way that all air pressure in it is 

released when the coupling is disconnected.
