Safety Precautions
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 material 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 prepunched holes.

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.
Thepowerfastenerdisplacestheconcretewhichtriestoreturntoitsoriginal form causing a squeezing effect.
Maximum holding power is achieved when the depth of penetration produces a bond on the power fastener equal to the strength of the concrete.
As a general rule, penetration should be approximately 1" to 1 1/4" into the base concrete. Make sure the concrete is at least three timesasthickastheintendedpowerfastenerpenetration.NEVER have the power fastener point protrude thru the concrete.
NOTE:Concreteneedstocurefor28daysbeforemaximum 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 continues down, thewaterclosesback.Thisissimilar
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 power fastener does not penetrate, the spring action of the steel pushes back on the point and tends to force the power fastener out.
Recommended applications are between 3/16-3/8" steel.
NOTE: When fastening in steel be sure the point goes thru the steel.
12 |
101274 |
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 1/4" into the base concrete material.
Wood or Non-Metals To Concrete
FASTENING INTO STEEL
Theproperpowerfastenerlengthcan 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 (gray-level 1). If the first test power 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:Damagetothe tool will result if the above instructions are not followed (see illustrations to right and lower right).

NOTE: NEVER fire the tool without a power fastener.This can damage thetooland/orcausepossibleinjury to the operator.
Piston Extended
Out of Muzzle
IMPORTANT: DO NOT use power fasteners longer than 2 1/2", or power washer fasteners longer than 3". Power fasteners longer than 2 1/2" and power washer fasteners longer than 3" will cause load ejection problems.

Operation
1.Grasp muzzle and slide barrel forward rapidly until it stops. This sets piston into firing position and opens the chamber.
2.Insert power fastener into muzzle of tool, head end first.Push thepowerfasteneruntilpointisevenwithendoftool.ALWAYS load the power fastener first, then the power load.
NOTE:
Failure to start with thelowestpowerlevel canresultinoverdrive condition and will result in damage to tool (see page 13).

4. Push barrel into housing to the closed position.

Operation
90˚
5.Place the muzzle of tool perpendicular to work surface without tilting the tool. Push tool against work surface until sliding action of barrel stops.
6.Squeeze trigger to set power fastener. Be sure to keep pressure on tool during this operation.
7.After fastening is made, slide barrel forward rapidly. This motion ejects the spent power load and resets the piston for the next fastening. Make sure spent load has ejected from tool.

8.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 againsttheworksurface.Againpressthetoolfirmlyagainst 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 unloading and carefully discarding the misfired power load into water or oil.
101274 |
15 |
Operation
PISTON OVERDRIVE
If the tool does not open after firing and the piston is 1/2 inch or more out of the muzzle:
1.Strike muzzle end of Powerdriver™ against hard surface to force piston back into muzzle.
2.Eject the power load (See step 7 of Operation).
OVERDRIVE
CARE OFYOUR POWERDRIVER™
Clean your Powerdriver™ after each day’s use.Clean chamber with accessory wire brush, part number 56485 (Not included with tool).Apply good quality penetrating lubricant spray (such as WD-40) sparingly and wipe dry.
NOTE: The labor regulations of many states require that the operator of this tool on a job site be thoroughly trained and certified for compentence prior to operating this tool. For certification procedures, call: Technical Services Department, 1-800-858-8501 or visit www.desatech.com.
