b. Do not force the tool. Use the
correct tool for the application. The
correct tool will do the job better and
safer at the rate for which the tool is
designed.
c. Do not use the tool if the trigger
does not turn the tool on or off.
Any tool that cannot be controlled
with the trigger is dangerous and
must not be used until repaired.
d. Disconnect the tool from the
air source before making
adjustments, doing tool
maintenance, clearing jams,
touching the safety nosepiece,
leaving work area, loading,
or unloading the tool. Such
precautionary measures reduce the
risk of injury to persons.
e. Store the tool when it is idle out
of reach of children and other
untrained persons. A tool is
dangerous in the hands of untrained
users.
f. Maintain the tool with care. A
properly maintained tool reduces
the risk of binding and is easier to
control.
g. Check for misalignment or binding
of moving parts, breakage of
parts, and any other condition
that affects the tool’s operation.
If damaged, have the tool serviced
before using. Many accidents are
caused by poorly maintained tools.
There is a risk of bursting if the tool is
damaged.
h. Use only accessories that are

plug and quick coupler, will make
operation more efcient, but are not
required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air ow, and therefore tool
performance, can be hindered by
undersized air supply components.
3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.
4. Release the tool’s trigger.
5. Close the in-line safety valve between
the compressor and the tool.
6. Turn on the air compressor according
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
7. Adjust the air compressor’s output
regulator so that the air output is
enough to properly power the tool,
but the output will not exceed the
tool’s maximum air pressure at any
time. Adjust the pressure gradually,
while checking the air output gauge
to set the right pressure range.
8. The air pressure setting must
not exceed job site regulations/
restrictions. The air pressure setting
must not exceed 90 PSI when being
used with work pieces that have a
thickness of less than 1-3/4”.
9. Inspect the air connections and the
tool for leaks. Repair any leaks
found.
10. If the tool will not be used at this time,
turn off and detach the air supply,
safely discharge any residual air
pressure, and release the trigger to
prevent accidental operation. As
added safety, the Magazine should
also be emptied of any fasteners.
Note: Residual air pressure should not be
present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion
after disconnecting to ensure that the
tool is disconnected and unpowered.
