Selecting Power Fasteners
and Power 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 power fastener that will actually penetrate
the concrete. The concrete must be three times as thick
as the intended power fastener penetration. In most
cases, penetration should be approximately 1" to 1
1 /

"
into the base concrete material.
FASTENING INTO STEEL
The proper power 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.
POWER LOADS
Always start with the lowest power level (green-level
3). If the first test power fastener does not penetrate
to the desired depth, move to the next highest power
level (yellow-level 4). 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).
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.
NOTE: NEVER fire the tool without a power fastener.
This can damage the tool and/or cause possible injury
to the operator.
