Safety Precautions
7. An operator taking medication should take extra precautions while handling the
tool. NEVER drink alcoholic beverages or take medications which impair your
vision, balance, or judgement before using a powder actuated tool.
KNOW YOUR FASTENING BASE MATERIAL
1. ALWAYS know the thickness and type of base material into which you are fasten-
ing. 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 power load (Green-Level
3) and proceeding with the order shown in the lower right-hand figure above.
Operators and bystanders must ALWAYS wear eye and ear protection which
meet or exceed the accepted standards for adequate protection in your country.
In the USA, refer to ANSI standards. In Canada, refer to CSA standards.
