BEFORE USING
1. ALWAYS handle the tool
as if it were loaded. Before
starting work, check that
the tool is unloaded and
the muzzle is clear. NEVER
load a tool unless it is going
to be used.
2. ALWAYS inspect to make sure the tool is working properly.
If the tool does not work properly, remove from service and
tag DEFECTIVE. DO NOT use the tool again until it has
been properly repaired.
3. Operators and bystanders must ALWAYS wear goggles
and ear protection which meet or exceed the accepted
standards for adequate protection in your country. In the
USA, refer to ANSI standards. In Canada, refer to CSA
standards.

5. ALWAYS make sure the work area is clean from loose
material and debris.
1. NEVER place your hand over the muzzle. Accidental dis-
charge can cause serious injury.
HANDLING THE TOOL
2. NEVER place your finger on the trigger until the muzzle of
the tool is against the work surface.
4. ALWAYS clear the work area on all sides and post appropri-
ate warning signs on job sites.

3. ALWAYS store UNLOADED powder actuated tool and
power loads in a locked container. Keep power loads of
different power levels in separate containers.
5. Ifthetoolisdropped,inspectfordamageandrepairitbefore

7. An operator taking medi-
cation should take extra
precautions while handling
the tool. NEVER drink al-
coholic beverages or take
medications which impair
your vision, balance, or
judgement before using a
powder actuated tool.
KNOW YOUR FASTENING BASE MATERIAL
1. ALWAYS know the thickness and type of base material
into which you are fastening. NEVER GUESS. Test the
base material by using the Center Punch Test. The Center
Punch Test is performed by using a hammer to test drive
the particular power fastener to be used into the material.
If the point penetrates easily, the material is too soft. If the
point becomes blunt, the material is too hard. If the material
fractures, cracks or shatters, the material is too brittle. Test
fastenings can be made if the material shows a clear power
fastener impression and the power fastener point is not
blunted. ALWAYS start with the lowest power load (Gray-
Level 1) and proceeding with the order shown in the lower
right-hand figure above. Operators and bystanders must
ALWAYS wear goggles and ear protection which meet or
exceed the accepted standards for adequate protection
in your country. In the USA, refer to ANSI standards. In
Canada, refer to CSA standards.

3. NEVER make fastenings in spalled or cracked areas.
2. NEVER attempt to drive power fasteners into very hard or
brittle materials including, but not limited to cast iron, glass,
tile, stone, brick, or hardened steel. Materials of this type
tend to shatter and create hazard from flying particles.
4. NEVER drive power fasteners into thin or easily penetrated
material unless it is backed by concrete or steel. When in
doubt, such as when base material is concealed, conduct
a Center Punch Test (See page 6). Check continually to
avoid fastening into unsuitable material, especially in older
buildings.
5. DO NOT fasten through or within 1/2" of predrilled or pre-
punched holes.

7. DO NOT drive power fasteners into steel base material
less then 3/16" thick, within 2" of a weld, within 1/2" of the
edge, or within 1" of another power fastener.

6. DONOT drive power fasteners into concretelessthan three
times as thick as the intended power fastener penetration,
within 3" of the edge, within 3" of another power fastener,
or within 3" of a failed power fastener.
8. When fastening into masonry walls, always drive into
horizontal mortar joints, NEVER into vertical mortar joints.
BE CAREFUL, a poorly laid joint may permit too much
penetration and/or unsatisfactory holding power.

3. ALWAYS use the spall shield when driving directly into
concrete or steel. ALWAYS wear eye protection.
4. NEVER use a powder actuated tool in an explosive or
flammable atmosphere or when non-sparking tools are
required.
POWER LOADS AND POWER FASTENERS
1. NEVER leave unfired power loads on floors or work surfaces.
2. Should the tool fail to fire, hold the muzzle firmly against
the work surface for 30 seconds. Release the trigger and
remove pressure on the tool while holding the muzzle
against the work surface.Again press the tool firmly against
the work surface and pull the trigger. If the tool still fails to
fire, hold the tool firmly against the work surface for another
30 seconds before unloading and carefully discarding the
misfired power load into water or oil.
