BEFORE USING  
?
?
1. Always handle the tool as if it were loaded. Before starting work, check that the  
tool is unloaded and the muzzle is clear. Never load a tool unless it is going to  
be used.  
2. Always inspect to make sure the tool is working properly. If the tool does not  
work properly, remove from service and tag “DEFECTIVE.” Do not use the tool  
again until it has been properly repaired.  
3. Operators and bystanders must wear goggles and ear protection which meet  
or exceed the accepted standards for adequate protection in your country. In  
the U.S.A., refer to ANSI standards. In Canada, refer to CSA standards.

1. Always know the thickness and type of base material into which you are  
fastening. Neverguess. TestthebasematerialbyusingtheCenterPunchTest.  
The Center Punch Test is performed by using a hammer to test drive the  
particular power fastener to be used into the material. If the point penetrates  
easily, the material is too soft. If the point becomes blunt, the material is too  
hard. If the material fractures, cracks or shatters, the material is too brittle. Test  
fastenings can be made if the material shows a clear fastener impression and  
the fastener point is not blunted. Always start with the lowest power load  
(Green-Level 3) and proceeding with the order shown in the lower right-hand  
figure above. Always wear approved goggles.

2. Never attempt to drive power fasteners into very hard or brittle materials  
including, but not limited to cast iron, glass, tile, stone, brick, or hardened steel.  
Materials of this type tend to shatter and create hazard from flying particles.  
3. Never make fastenings in spalled or cracked areas.  
4. Never drive power fasteners into thin or easily penetrated materials unless it is  
backed by concrete or steel. When in doubt, such as when base material is  
concealed, conduct a Center Punch Test (See page 6). Check continually to  
avoid fastening into unsuitable material, especially in older buildings.  
5. Do not fasten through or within 1/2" of predrilled or pre-punched holes.

holding the muzzle against the work surface. Again press the tool firmly  
against the work surface and pull the trigger. If the tool still fails to fire, hold  
the tool firmly against the work surface for another 30 seconds before  
advancing the power load strip. Use remaining loads in strip. Discard power  
load strip into water or oil.

Fasteners are manufactured from special steel and heat treated to produce a

serious injury (See Troubleshooting Guide, page 23).

Why A Power Fastener Holds  
WHY A POWER FASTENER HOLDS  
IN CONCRETE  
The compression bond of the concrete to the power  
fastener accounts for the majority of the holding power.  
The fastener displaces the concrete which tries to return  
to its original form causing a squeezing effect.  
482-64  
Maximum holding power is achieved when the depth of  
penetrationproducesabondonthepowerfastenerequal  
to the strength of the concrete. As a general rule, pene-  
tration should be approximately 1" to 1 1/4" into the base  
concrete. Make sure the concrete is at least three times  
asthickastheintendedfastenerpenetration.Neverhave  
the power fastener point protrude through the concrete.  
NOTE: Concrete needs to cure for 28 days before  
maximum fastening holding power will be achieved.  
WHY A POWER FASTENER HOLDS IN STEEL  
Holding power in steel depends on the elasticity of the  
steel. The steel pushes back on the shank of the power  
fastener.  
Drop a marble into water; the water parts, the marble  
482-65  
continues down, the water closes back. This is similar to  
the reaction when a power fastener penetrates steel.  
In steel, the point of the power fastener must penetrate  
completely through for highest holding power. If the  
fastener does not penetrate, the spring action of the steel  
pushes back on the point and tends to force the fastener  
out.  
Recommended applications are between 3/16-3/8"  
steel.  
NOTE: When fastening in steel be sure the point goes  
through the steel.

Selecting Power Fasteners  
and Power Loads  
FASTENING INTO CONCRETE  
The proper power fastener length can be determined by  
addingthethicknessofthematerialtobefastenedandthe  
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  
shouldbeapproximately1"to11/4"intothebaseconcrete  
material.  
482-85  
Wood or Non-Metals  
To Concrete  
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.  
482-79  
Wood or Non-Metals  
To Steel  
POWER LOADS  
RIGHT  
Always start with the lowest power level (green-level 3). If  
the first test 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).  
482-66

OVERDRIVEN POWER FASTENERS  
AND PISTON  
OVERDRIVE  
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.  
482-67  
Piston Extended  
Out of Muzzle  
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.

Operation  
1. Grasp barrel assembly and slide forward rapidly until it stops. Push barrel  
assembly back into tool to the closed position. This sets piston into firing  
position.  
482-70  
482-71  
2. Insert power fastener into muzzle of tool, head end first. Push the fastener until  
point is even with end of tool.  
NOTE:  
Failure to start with  
the lowest power  
level can result in  
overdrive condition  
and will result in  
damage to tool  
(See page 13).  
3. Select the proper power level of power load strips. Always insert powder strip  
loads through bottom of handle. Push power load strip in until even with bottom  
of handle.  
90˚  
4. Place the muzzle of tool perpendicular to work surface without tilting the tool.  
Push tool against work surface until sliding action of barrel stops.

Operation  
5. Squeeze trigger to set power fastener. Be sure to keep pressure on tool during  
this operation.  
6. Grasp base plate and slide barrel forward rapidly until it stops. Push base plate  
back into liner to the closed position. This advances the power load strip and  
resets the piston for the next fastening.  
WARNING: Do not depress muzzle of tool into barrel assembly when  
loading new power fastener. Live power load is in firing position.

7. Should the tool fail to fire, hold the muzzle firmly against the work surface for  
30 seconds. Release the trigger and remove pressure on the tool while  
holding the muzzle against the work surface. Again press the tool firmly  
against the work surface and pull the trigger. If the tool still fails to fire, hold  
the tool firmly against the work surface for another 30 seconds before  
advancing the power load strip. Use remaining loads in strip. Discard power  
load strip into water or oil.
