Selecting Power Fasteners
and Powder Loads
FASTENING INTO CONCRETE
The proper power fastener length can be determined
by adding the thickness of the material to be fastened and
the amount of fastener that will actually penetrate the
concrete. The concrete must be three times as thick as the
intended fastener penetration. In most cases, penetration
should be approximately 1" to 1 1/4" into the base concrete
material.
FASTENING INTO STEEL
The proper fastener length can be determined by
adding the thickness of the material to be fastened and the
thickness of the steel. The point of the power fastener
must go completely through the steel.
Flush With Surface
POWDER LOADS
Always start with the lowest power level (gray-level
1). If the first test fastener does not penetrate to the
desired depth, move to the next highest power level
(brown-level 2). Increase until a proper fastening is made.
IMPORTANT: Damage to the tool will result if the above
instructions are not followed (see illustrations to right and
lower right).
Piston Extended
Out of Muzzle
OVERDRIVEN POWER FASTENERS
AND PISTON
An overdriven power fastener results when too
strong of a powder load is used causing the piston to
extend past the muzzle. Move to the next lightest powder
load. Repeated overdrive will damage your tool. By avoid-
ing overdrive, you can extend the life of your tool consid-
erably and avoid costly repairs.
NOTE: NEVER fire the tool without a power fastener. This
can damage the tool and/or cause possible injury to the
operator.
IMPORTANT: DO NOT use power fasteners longer than
2 1/2". Fasteners longer than 2 1/2" will cause load
ejection problems.
