Safety Precautions

7. An operator taking medication should take extra precau-

tions while handling the tool. NEVER drink alcoholic bever-

ages 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 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.
