FASTENING INTO CONCRETE

The proper power fastener length

can be determined by adding the

thickness of the material to be fas-

tened and the amount of fastener

that will actually penetrate the con-

crete. The concrete must be three

times as thick as the intended fas-

tener penetration. In most cases,

penetration should be approxi-

mately 1" to 1

" into the base

concrete material.

FASTENING INTO STEEL

The proper fastener length can be

determined by adding the thick-

ness of the material to be fastened

and the thickness of the steel. The

point of the power fastener must go

completely through the steel.

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 in-

structions are not followed (see il-

lustrations to right and lower right).

OVERDRIVEN POWER

FASTENERS AND PISTON

An overdriven power fastener re-

sults 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

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

or power washer fasteners longer than 3". Power fasteners

longer than 2

" and power washer fasteners longer than 3" will

cause load ejection problems.
