Safety Precautions
3. NEVER make fastenings in spalled or cracked areas.
2. NEVER attempt to drive power fasteners into very hard or brittle materials in-
cluding, 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.
