Safety Precautions
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. ALWAYSknow the thickness and typeof base material into
which you are fastening. NEVER GUESS. Test the base
materialby using theCenter PunchTest.The CenterPunch
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
fastener impression and the fastener point is not blunted.
Alwaysstartwith the lowestpowderload (Gray-Level 1)and
proceeding with the order shown in the lower right-hand
figure above. ALWAYS wear approved eye protection.

Safety Precautions
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 pen-
etrated 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 con-
tinually to avoid fastening into unsuitable material, espe-
cially in older buildings.
5. DO NOT fasten thru or within 1/2" of predrilled or pre-
punched holes.

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 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.
POWDER LOADS AND FASTENERS
1. NEVER leave unfired powder 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 dis-
carding the misfired powder load into water or oil.

3. NEVER use powder loads in firearms.
5. A color blind person must take extra precautions to prevent
the chance of mixing the powder loads of various levels.
4. NEVER carry fasteners or other hard objects in the same
pocket or container with powder loads.
2. Remington®Powder 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 fasten-
ing is made (see page 13, Selecting Fasteners and Loads ).
