the tool to a compressor rated at over 200 psi. The tool operating
pressure must never exceed 200 psi even in the event of regulator
failure. (Fig. C)
• Only use air hose that is rated for a maximum working
pressure of at least 150 PSI (10.3 BAR) or 150% of the
maximum system pressure, which ever is greater. (Fig. D)
• Do not use bottled gases to power this
tool. Bottled compressed gases such as
oxygen, carbon dioxide,
hydrogen, propane, acetylene or air are
not for use with pneumatic tools. Never
use combustible gases or any other
reactive gas as a power source for this tool.
Danger of explosion and/or serious
personal injury may result. (Fig. E)
• Use couplings that relieve all pressure
from the tool when it is disconnected
from the power supply. Use hose
connectors that shut off air supply from
compressor when the tool is disconnected.
(Fig. F)
• Disconnect tool from air supply when
not in use. Always disconnect tool
from air supply and remove fasteners
from magazine before leaving the
area or passing the tool to another
operator. Do not carry tool to another
work area in which changing location
involves the use of scaffoldings, stairs,
ladders, and the like, with air supply
connected. Do not make adjustments,

remove magazine, perform maintenance or clear jammed
fasteners while connected to the air supply. If the contact trip is
adjusted when the tool is connected to the air supply and fasteners
are loaded, accidental discharge may occur. (Fig. G)
• Connect tool to air supply before
loading fasteners, to prevent a
fastener from being fired during
connection. The tool driving mechanism
may cycle when tool is connected to the
air supply. Do not load fasteners with
trigger or contact trip depressed, to
prevent unintentional firing of a fastener.
• Do not remove, tamper with, or
otherwise cause the tool, trigger, or
contact trip to become inoperable.
Do not tape or tie trigger or contact trip
in the on position. Do not remove spring
from contact trip. Make daily inspections
for free movement of trigger and contact
trip. Uncontrolled discharge could result.
• Inspect tool before use. Do not
operate a tool if any portion of
the tool, trigger, or contact trip is
inoperable, disconnected, altered,
or not working properly. Leaking air,
damaged parts or missing parts should
be repaired or replaced before use.
(Fig. H)
• Do not alter or modify the tool in any
way. (Fig. I)
• Always assume that the tool contains fasteners.
