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

OVERDRIVEN POWER FASTENERS
AND PISTON
An overdriven power fastener results when too strong of a
power load is used causing the piston to extend past the
muzzle. Move to the next lightest power load. Repeated
overdrive will damage your tool. By avoiding overdrive, you
can extend the life of your tool considerably 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

POWER 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).
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.
