rules of safe operation. Read carefully and become familiar
before operating to avoid serious injury. We expressly disclaim
any liability for any injury to persons or damage to property
which result from your failure to take the precautions contained
in this manual.
WARNING: This tool is designed only for use by qualified
operators. Qualification is obtained through a thorough under-
standing of the Safety Precautions and operating instructions
as defined in this operating manual. NOTE: The labor regula-
tions of many states require that the operator of this tool on

BEFORE USING
1. ALWAYS handle the tool as if it were loaded. Before start-
ing 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 ANSI 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.

4. NEVER carry or pass a loaded powder actuated tool.
NEVER point a powder actuated tool at anyone.
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. If the tool is dropped, inspect for damage and repair it before
continuing to work. NEVER use a damaged tool.
6. ALWAYS take precautions to maintain your balance while
operating a powder actuated tool.

7. An operator taking medication should take extra precau-
tions while handling the tool. NEVER drink alcoholic bever-
ages 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 ma-
terial 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 pen-
etrates 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 impres-
sion 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.
ALWAYS wear approved eye protection.

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. DO NOT drive power fasteners into concrete less than 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.

1. ALWAYS hold tool perpendicular to work surface.

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.

2. Remington® Power Loads are available in four power levels with
gray (1) being the lowest power level and yellow (4) being the
highest power level. Always start with the lowest power level
(gray-level 1) and increase until a proper fastening is made (see
page 13, Selecting Power Fasteners and Power Loads).
3. NEVER use power loads in firearms.
4. NEVER carry power fasteners or other hard objects in the
same pocket or container with power loads.
5. A color blind person must take extra precautions to prevent
the chance of mixing the power loads of various levels.
