4. ALWAYS clear the work area on all sides and post appropri-

ate warning signs on job sites.

5. ALWAYS make sure the work area is clean from loose

material and debris.

HANDLING THE TOOL

1. NEVER place your hand over the muzzle. Accidental dis-

charge can cause serious injury.

2. NEVER place your ﬁnger on the trigger until the muzzle of

the tool is against the work surface.

101274

7. An operator taking medication should take extra precautions while handling the tool. NEVER drink alcoholic beverages or take medications which impair your vision, balance, or judgement before using a powder actuated tool.

KNOW YOUR FASTENING BASE MATERIAL

1. ALWAYS know the thickness and type of base material into

which you are fastening. NEVER GUESS. Test the base ma- terial by using the Center Punch Test. 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 power fastener impression and the power fastener point is not blunted. Always start with the lowest power load (Gray-Level 1) and proceeding with the order shown in the lower right-hand ﬁgure above. ALWAYS wear approved eye protection.

101274

Safety Precautions

CAST IRON GLASS

TILE

BRICK

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 pre-

punched holes.

Safety Precautions

6. Power fasteners are a permanently installed ﬁxture. An

act of demolition is required for their removal. Appropriate safety precautions must be taken.

7. NEVER use common nails or other materials as fasteners. Remington® Power Fasteners are manufactured from special steel and heat treated to produce a very hard, yet ductile, fastener.

8. NEVER pry a power load out of the chamber. Prying can discharge the load causing serious injury (see Trouble- shooting Guide on pages 21 and 22).

9. ALWAYS insert the power fastener ﬁrst, then the power load. If work is interrupted for any reason, ALWAYS remove the power load before removing the power fastener (see page 15, item 7).

101274

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 power fastener displaces the concrete which tries to return to its original form causing a squeezing effect.

Maximum holding power is achieved when the depth of penetration pro duces 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 times as thick as the intended power fastener penetration. NEVER have the power fastener point protrude thru 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 continues down, the water closes back. This is similar to the reaction when a power fas tener penetrates steel.

In steel, the point of the power fastener must penetrate com pletely 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.

101274

Selecting Power

OVERDRIVE

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 concrete material.

/4" into the base

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 (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: Damage to the tool will result if the above instruc tions 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.

IMPORTANT: DO NOT use power fasteners longer than 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

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 the power fastener until point is even with end of tool. ALWAYS load the power fastener ﬁrst, then the power load.

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 Remington® Power Load (see Application Chart on pages 22 and 23) and insert into the chamber until

it stops.

4. Push barrel into housing to the closed position.

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.
