ALWAYS know the thickness and type of base material into which you are fastening. NEVER
GUESS. Test the base material 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 fastener impression and the 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 goggles.

482-33

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.

G 018

3.

NEVER make fastenings in spalled or cracked areas.

G 018

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.

8.

NEVER pry a power load out of the tool. Prying can discharge the load causing serious injury
(see Troubleshooting Guide, page 16).

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).

101437

11

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.
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 times as thick as the intended fastener penetration. NEVER
have the power fastener point protrude through the concrete.

482-64

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 fastener penetrates steel.

482-65

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.

101437

12

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 concrete. 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.

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
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 instructions
are not followed (see illustrations to right and lower right).

RIGHT

482-66

Flush With Surface

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.
G 018

NOTE: NEVER fire the tool without a power fastener. This can
damage the tool and/or cause possible injury to the operator.

Operation

1.

Grasp muzzle and slide barrel forward rapidly until it stops. This sets piston into firing position
and opens the chamber.

482-70

2.

482-71

Insert power fastener into muzzle of tool, head end first. Push the fastener until point is even
with end of tool. ALWAYS load the fastener first, then the power load.

482-72

482-71

NOTE:
Failure to start with
the lowest power
level can result in

and will result in
damage to tool
(see page 13).

3.

Select the proper Remington Power Load and insert into the chamber until it stops (see
Application Chart on page 23).

4.

Push barrel into housing to the closed position.

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.

WARNING ICON

G 001

WARNING: Always unload a powder actuated tool before disassembling, replacing barrel,
cleaning, or assembling.

TO REASSEMBLE:

IMPORTANT: This tool is equipped with a
piston buffer. The buffer stops the piston before
it makes contact with the muzzle cap. This
protects the barrel and muzzle cap. Inspect and
replace the buffer on a regular basis.

New Piston
Buffer

IMPORTANT: Inspect piston ring and replace
if worn.
1. Install new piston ring onto piston (if required).
a) Remove old piston ring.
b) Install new ring. The piston ring consists of
three turns. Place one end into groove
and twist around piston until it is completely in groove.
