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.
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 power load (Gray-Level 1) and proceed with the order
shown in the lower right-hand figure above. Always wear approved goggles.
