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 fastener that will actually penetrate the con- crete. 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.

Always start with the lowest power level
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 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: Only use 2 1/2" power fasteners with the standard guide. 3" power fasteners can be used with optional guide, part number 301110.
