Safety Precautions
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
fasteningscanbemadeifthematerialshowsaclearfastenerimpressionandthefastenerpoint
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 goggles.

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 penetrated materials 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.
