AIRSUPPLY
LINE
See Figure 3
DANGER: Do not use oxygen, carbon dioxide,
high-pressure compressed gas or bottled gases as
the power source for this tool. The tool will explode
and serious personal injury could result.
• The air tool operates on compressed air at pres-
sures from 70-120 PSI
• Never connect the tool to air pressure which
could potentially exceed 200 PSI. Use only
clean, dry, regulated air within rate range as
marked on tool.
Air delivery Required: 0.94 SCFM @ 90 PSI. (30
shots per minute).
WARNING: Keep hands and body away from
discharge area of tool when connecting air supply.
Always disconnect tool from air supply when servicing
or adjusting tool and when tool is not in use.
• Air operated tools require clean, dry, lubricated
compressed air to ensure top performance, low
maintenance and long life.
• Dirt and abrasive materials present in all air lines
will damage tool O-rings, valves and cylinders.
• Moisture will reduce tool performance and life if
not removed from compressed air.
• The air supply system must be able to provide
air pressure of 70-120 pounds per square inch at
tool.
• All hoses and pipes in the air supply system must
be clean and free of moisture and foreign parti-
cles. Hoses must be rated for maximum working
pressure of 150 PSI or 150% of maximum system
pressure, whichever is greater.
• Do not mount swivel connector in air supply line.
• The air pressure should be properly regulated.
• Different workpiece materials and different
fastener lengths will require different operating
pressure.
• Be sure all connections in air supply system are
sealed to prevent air loss.
WARNING: This tool is equipped with a male, free-
flow coupling for air supply connection. To prevent
accidental discharge and possible injury, NEVER
remove the male coupling to replace with a female
coupling.
To connect tool to air supply:
1. Firmly hold tool by its handle with one hand. Be
sure to point tool away from you and others in
the area.
2. With other hand, insert female coupling of air
hose over male coupling of tool until hose cou-
pling is firmly seated.
CAUTION: When connecting or disconnecting air
hose, air pressure may cause the the hose coupling
to kick back if the hose coupling is not firmly seated
on tool coupling.
NOTE: When hose is disconnected from tool, snap
the dust cap over the tip of the tool male coupling.
