AIR SUPPLY
 
DANGER
• 
NEVER use oxygen or other bottled 
      gases. Explosion may occur.
 
WARNING
• 
Never connect Tool to pressure which potentially exceeds 200 
psi (13.7 bar 14 kgf/cm
2
).
• 
Never use non relieving coupler on Tool.
1. Power Source
V
  Use only clean, dry, regulated compressed air as a power source 
for this Tool
V
  Air compressors used to supply compressed air to this Tool 
must comply with the requirements of the latest version of ANSI 
Standard B 19.3 “Safety Standard For Compressors For Process 
Industries.”
V
  Moisture or oil in the air compressor may accelerate wear and 
corrosion in the Tool. 
Drain daily.
V
  Air volume is as important as air pressure. The air volume 
supplied to the tool may be inadequate because of undersized 
fittings and hoses or from the effects of dirt and water in the 
system. Restricted air flow will prevent the tool from receiving 
an adequate volume of air, even though the pressure reading is 
high. The results will be slow operation, jamming, miss‑feeds 
or reduced driving power. Before evaluating tool problems for 
these symptoms, trace the air supply from the tool to the supply 
source for restrictive connectors, swivel fittings, low points con‑
taining water and anything else that would prevent full volume 
flow of air to the tool.
2. Filter‑Regulator‑Lubricator
V
  A pressure regulator with an operating pressure of 0‑125 psi 
(0‑8.6 bar   0‑8.8 kgf/cm
2
) is required to control the operating 
pressure for safe operation of this Tool. Do not connect this Tool 
to air pressure which can potentially exceed 200 psi as Tool may 
fracture or burst, possibly causing injury.
V
  Filter‑Regulator‑Lubricator units supply an optimum condition 
for the Tool and extend the Tool life.
