or cracked areas.
Safety Precautions
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 material by using the
Center Punch Test. The Center
Punch Test is performed by using a
hammer to test drive the particular
fastener to be used into the mate-
rial. 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 should
always be made starting with the
lowest power load (Gray-Level 1)
and proceeding with the order
shown. Operators and bystanders
must ALWAYS wear goggles and
ear protection that meet or exceed
CE standards.
2. NEVER attempt to drive fasteners
into very hard or brittle materials
including, but not limited to cast
iron, glass, tile, stone, brick, or hard-
ened steel. Materials of this type
tend to shatter and create hazard
from flying particles.
