DANGER
Just as no one can merely read a book about driving an automobile and then hope
to drive one safely, no one should attempt to use any Ramset tool without adequate,
competent personal instruction. And just as one must be licensed to drive an
automobile, one must also be licensed to use a powder actuated tool.
No automobile instruction book or instructor can forewarn a learner against all pos-
sibilities and emergencies, nor can ITW Ramset/Red Head instructors and printed
material detail all possible conditions surrounding the use of ITW Ramset/Red Head
tools and products.
Responsibility for the safe and proper use of this tool rests with the tool
user and the employer.

Preparation
Acceptable Base Materials
Powder actuated fastening is suit-
able for use in the following base
materials only:
• Poured Concrete
• Structural Steel
• Masonry Joints ( see page 8)
Never attempt to fasten into any
other type of material. Fastening into
other materials can cause blindness or
other serious injury.
Unacceptable Base Materials
Never attempt to fasten into very
hard or brittle materials such as cast
iron, tile, glass, or rock of any type.
These materials can shatter, causing
the fastener and/or base material
fragments to fly free and cause
serious injury to the tool operator
and others.
Never fasten into soft base
materials, such as drywall or lumber
products. These materials may allow
the fastener to travel completely through
and out the other side, endangering
those in the path of the fastener.
Never fasten into any base material
that does not pass the Center Punch
test. Failure to assure the suitability of
the base material can result in serious
injury to the eyes or other body parts.
NEVER FASTEN INTO VERY
HARD OR BRITTLE MATERIALS
NEVER FASTEN INTO SOFT
MATERIALS SUCH AS DRYWALL
Center Punch Test
ALWAYS WEAR SAFETY GOGGLES
WHEN PERFORMING THIS TEST.
1. Always check the material
being fastened into for hard-
ness before attempting any
fastening operation.
2. Using a fastener as a center
punch, strike the fastener
against the work surface using
an average hammer blow and
check the results.
Center Punch Test Results
1. If the fastener point is flattened,
the material is too hard for a
powder actuated fastening.
2. If the fastener penetrates the
material easily, the material is
too soft.
3. If the material cracks or
shatters, the material is too
brittle.
4. If the fastener makes a small
indentation into the material,
the material is suitable for
fastening.

Loads & Load Selection Safety
1. Always make a test fastening
after being sure that the base
material is suitable for powder
actuated fastening. Failure to
determine the correct power level
to be used may result in the use
of excessive power, allowing the
fastener to pass completely
through the work material,
causing serious or fatal injuries to
others who may be in the path of
the fastener.
2. Color-blind operators must al-
ways select disc loads by number
to prevent use of an incorrect
load for the same reasons as in #1
above.
Workplace Safety
1. Operators and bystanders must
always wear approved safety
goggles and approved hearing
protection. Failure to do so may
result in blindness or serious eye
injury from flying debris and loss
of hearing from constant or
repeated unprotected exposure to
fastening noise.
2. Always keep the work area clear
of bystanders and unnecessary
materials that could interfere with
safe tool operation. Operating the
tool in a congested or cluttered
area may affect your ability to
operate the tool safely.
3. Never operate tool if flammable or
explosive materials are nearby.
Powder loads burn and create
sparks when fired and could ignite
these materials or fumes.
4. Always post warning signs within
50’ of the area where fastening is
to be done. Sign must state:
“Caution- Powder Actuated Tool
In Use”. Failure to warn others may
result in serious injury to them. Con-
tact ITW Ramset/ Red Head at
1-800-354-7432 to obtain this

SAFETY INSTRUCTIONS
Tool Handling Safety
1. Always be sure tool is operating
properly before attempting to
use it. Follow the “Daily
Function Check” shown to the
right and described on page 9.
2. Always load tool using a disc
load selected directly from a box
indicating the power load type
and number. Never attempt to use
loose disc loads that could be
mis-identified.
3. Never carry loose disc loads in
pockets with pins or other hard
objects.
4. Never load a tool unless you
intend to immediately make a
fastening. Loading a tool and
leaving it unattended in the work
area can result in the tool being
accidentally discharged by others.
5. Never place your hand or any
other body part over the fastener
loading end of the tool. Serious
hand injury could result from being
struck by either a fastener or the tool
piston should the tool be accidentally
fired.
6. Always store the tool unloaded
and keep the tool and the loads
securely locked in a tool box.
Keep keys away from children
and unlicensed persons.
7. Always keep the tool pointed
away from yourself and others.
8. Never carry a loaded tool around
the work area.
9. Never allow anyone not trained to
use the tool.
10.Never engage in horseplay with
the tool.
11.Using the tool in poorly ventilated
areas, cleaning tool or handling
loads may result in exposure to
lead or other substances known
to cause birth defects, and other
physical harm. Have adequate
ventilation at all times and wash
thoroughly after exposure.
ALWAYS DO A DAILY
FUNCTION CHECK BEFORE
LOADING THE TOOL
NEVER LOAD TOOL UNLESS IT
IS TO BE USED IMMEDIATELY
NEVER PLACE HANDS OR
BODY OVER MUZZLE OPENING
KEEP TOOL LOCKED & OUT OF
THE REACH OF CHILDREN

ATOR OR TO BYSTANDERS.
Fastener Driving Safety
1. Only use the tool for fastening
into a suitable base material.
2. Never fire the tool without a
fastener. Firing a tool without a
fastener will cause the piston to
strike the work surface, and may
cause serious injury to you and
others in the work area.
3. Always use the spall guard
whenever possible to minimize
flying particles or debris.
4. Always hold the tool perpendic-
ular to and firmly against the
work surface when making a
fastening. Failure to do so could
allow a fastenerto ricochet.
5. Never attempt to drive a fastener
close to an edge or to another
fastener. See page 8 for guidelines.
ALWAYS FOLLOW THE MISFIRE
PROCEDURE
If the tool does not fire after pull-
ing the trigger, continue to hold the
depressed tool against the work
surface for at least 30 seconds. Then
carefully open the tool, remove the load
disc, and put it in a can of water or other
non-flammable liquid. Never carelessly
discard a disc with live loads into a trash
container.
If the tool becomes stuck or jammed
with a live powder load, keep the tool
pointed in a safe direction, and immedi-
ately tag it, “Danger-defective-do not
use”. Lock the tool in a tool box and call
your local Ramset Distributor for assist-
ance.

FASTENING APPLICATIONS
FASTENING APPLICATIONS
8
FASTENING APPLICATIONS
Your Ramset tool can be used for a wide
range of fastening needs in a variety of
base materials. Reading and following
these important fastening guidelines will
help you get the best results from your
tool, fasteners, and powder loads, as
well as help you perform these fastening
operations safely and effectively.
Powder actuated fastenings are perm-
anent fastenings so attempting to
remove a fastener from concrete or
steel may result in serious injury.
Fastening to Concrete
When fastening into concrete, always
maintain a minimum spacing of 3"
between fastenings and 3" from any
free edge. Concrete thickness should
be at least three times the intended
penetration depth into the concrete. The
primary exception to the 3" edge
distance can occur in a sill plate
application where, by necessity, the
edge distance is reduced.
Driving fasteners too close to an edge
or too close to each other can cause
the concrete edge to fail or fasteners to
fly free.
Fastening to Concrete Block or
to Masonry Walls
While this application is not recom-
mended, when used, it is necessary to
take care to observe a 3” edge distance
to avoid cracking the block and over
penetration of the fastener to avoid a
loss of holding value. Fastenings may be
made into the horizontal joint but not into
the vertical joint.

TOOL OPERATION
Daily Function Test
Always check the tool first to make
sure that it does not contain a load
disc or fastener. Test the tool several
times by depressing the muzzle bushing
fully on a hard surface and pulling the
trigger. You should hear an audible click
as the firing pin releases.
PERFORM FUNCTION TEST
WITH EMPTY, UNLOADED TOOL
OPEN BARREL AND CLOSE TO
SEMI-CLOSED POSITION
INSERT FASTENER INTO THE
MUZZLE END OF THE TOOL
WITH THE POINT OUT
OPERATING THE D45 TOOL
1. After checking to be sure that
the tool is not loaded, point it in a
safe direction and be sure that
the barrel is fully extended. This
assures that the piston is in
position for the next fastening.
Use the spall guard every time
possible to minimize the risk of
being struck by flying debris.
2. With finger off the trigger, place
the fastener, point out, into the
muzzle end of the tool until the
point end is inside the muzzle.
NEVER load a fastener with
your finger on the trigger. DO
NOT use excessive force when
inserting a fastener. STOP
immediately if excessive force is
required, inspect the barrel to
find out why the fastener is not
entering the muzzle freely. DO
NOT continue loading unless
the problem is corrected.
3. With the tool pointed in a safe
direction and finger away from the
trigger, open the cover by pressing
the side button and insert a load
disc into the slots in the receiver
housing.

4. Close the cover and be sure it is
locked. NEVER attempt to make a
fastening with the tool cover in the
open or unlocked position.
5. Hold the tool perpendicular (90°) to
the work surface with both hands
and press firmly to fully depress the
tool. Maintain firm downward
pressure on the tool with both
hands and pull the trigger to drive
the fastener. DO NOT DEPRESS
THE TOOL AGAINST ANYTHING
OTHER THAN THE INTENDED
WORK SURFACE. Holding the tool
firmly in place will produce more
consistent fastening quality and
minimize tool wear or damage.
6. After making the fastening , with the
tool pointed in a safe direction pull
the barrel fully open.This resets the
piston for the next fastening.
Always keep fingers and other
body parts away from the
muzzle end of the tool.
7. Insert another fastener in the
muzzle end of the tool as before
and the tool is ready for the next
fastening. Keep your finger off of the
trigger until the tool is in position to
drive the fastener.
8. To remove a used or partially used
load disc from the tool, open the
cover and lift out the load disc.
NEVER try to remove a jammed or
stuck load disc. Should a “jammed”
load disc occur, call your local
Authorized Ramset Distributor for
technical assistance.
