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
fastener impression and the fastener point is not blunted.
Always start with the lowest powder load (Gray-Level 1) and
proceeding with the order shown in the lower right-hand
figure above. ALWAYS wear approved eye protection.

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.
G 018
3. NEVER make fastenings in spalled or cracked areas.
G 018
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 continually to avoid fastening into unsuitable material, especially in older buildings.
