THIS TOOL FOR USE BY LICENSED OPERATORS ONLY.
READ AND OBEY ALL SAFETY AND OPERATING
INSTRUCTIONS BEFORE OPERATING TOOL.
SEMI-AUTOMATIC, LOW VELOCITY
PISTON TYPE FASTENING TOOL
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 possibilities and emergencies, nor
can Ramset instructors and printed material detail all possible conditions surrounding the
use of Ramset 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 suitable 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.
Center Punch Test
ALWAYS WEAR SAFETY GOGGLES
WHEN PERFORMING THIS TEST.
1. Always check the material being
fastened into for hardness 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 always
select 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 eye protection
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 ft. of the area where fastening
is to be done. Sign must state:
“WARNING - Powder Actuated Tool
In Use”.
Failure to warn others
may result in serious injury to them.

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 perpendicular
to and firmly against the work
surface
when making a fastening.
Failure to do
so could allow a fastener
to 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 the normal
firing sequence, continue to hold the
depressed tool against the work surface
for at least 30 seconds. Then carefully lower
the tool, remove the strip load, and put it
in a can of water or other non-flammable
liquid. Never carelessly discard a strip 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 immediately tag it,
“Danger- defective - do not use”.
Lock
the tool in a tool box and call your local

listed for the tool in the Product Catalog.
FASTENERS
Never use any other types of fasteners or strip loads in the Ramset SA270 Tool. Use of other
types of fasteners or loads may cause unintentional load discharge, damage the tool, cause
poor fastening performance, or create a risk of serious injury to the operator or bystanders.
DANGER
LOADS
Ramset RS27 strip loads are specially made for use in the Ramset SA270 Tool.
The power level of the load is indicated by
the number marked on each box, the color
of the box, and the color on the tip of each
load. As the number increases, the power
level also increases.
Always perform the center punch test
described on page 3 to test the base material.
Always make a test fastening using the
lowest power level first. If more power is
required to set the fastener, use the next
higher power level until the powder level
necessary to drive the fastener is reached.

FASTENING APPLICATIONS
Your Ramset tool can be used for a wide
range of fastening needs in a variety of base
materials. Reading and follow 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 permanent
fastening 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 recommended,
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 loss of holding value. Fastening may
be made into the horizontal joint but not into
the vertical joint.
Fastening to Steel
Your Ramset tool can be used for fastening
on the flat surfaces of structural steel. When
fastening into steel, always maintain a minimum spacing of 1-1/2" between fastenings
and 1/2" from any edge.

TOOL OPERATION
Daily Function Test
Always check the tool first to make sure
that it does not contain a strip load 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. Let up on the tool and check to be
sure that the barrel has opened to the semiopen position.
OPERATING THE RAMSET
SA270 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 and then close the tool to the
semi-closed position. 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 require, 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, insert a load strip into the
bottom of the handle and push it in
until your finger is in firm contact with
the handle recess.

4. 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.
5. After making the fastening, fully open
and then close the tool to the semiclosed position. This resets the piston
and indexes a new load into place for
the next fastening.
6. 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.
7. To remove a used or partially used
strip load from the tool, pull the strip
out from the top of the tool. Do not try
to remove the strip by pulling it out from
the bottom of the handle. NEVER
try to remove a jammed or stuck
load strip. Should a “jammed” load
strip occur, call your local Authorized
Ramset Distributor for technical
assistance.
