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 power
fastener impression and the power fastener point is not
blunted. aLWaYS start with the lowest power load (Gray-
Level 1) and proceeding with the order shown in the lower
right-hand figure above. Operators and bystanders must
aLWaYS wear goggles 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.
