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 possibilities 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 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.

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 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.

SAFETY INSTRUCTIONS 4

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 load 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. Contact ITW Ramset/ Red Head at 1-800-354-7432 to obtain this sign.

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 power load selected directly from a box indicating the power load type and number. Never attempt to use loose loads that could be mis-identified.

3. Never carry loose 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.

FAILURE TO FOLLOW INSTRUCTIONS CAN CAUSE INJURY TO THE TOOL OPERATOR 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 perpendicular 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, and put it in a can of water or other nonflammable liquid. Never carelessly discard 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 Ramset Distributor for assistance.

USE THE SPALL GUARD

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 permenant fastenings so attempting to remove a fastener from concrete or steel may result in a 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 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 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 semi-closed position.

SLIDE THE BARREL

FORWARD

INSERT FASTENER INTO THE

MUZZLE END OF THE TOOL

WITH THE POINT OUT

OPERATING THE M70 TOOL

1. After checking to be sure that

the tool is not loaded, point it in a safe direction and pull the barrel open with a quick forward motion.This action positions the piston in preparation 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, the barrel fully open, and your finger away from the trigger, make sure the chamber is clear and insert a load into the tool chamber. Always start with the #1, gray power level. If the #1 load does not fully set the fastener, try the next higher power level until the proper power level is found.

TOOL OPERATING INSTRUCTIONS

4. Slide the barrel back to the semi-

closed position. Never attempt to close the tool by exerting force on the front end of the barrel. Never

place your hand, fingers or any other body part over the fastener loading end of the tool.

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, point the

tool in a safe direction, and pull the barrel forward to cause the barrel to move to the open position. This action ejects the fired load case and properly resets the piston for the next fastening. Should a fired load fail to eject, open and close the tool several times to loosen the load in the chamber, then remove the load with your fingers. Never attempt to

pry an unfired load out of the tool chamber. The load could be

caused to discharge resulting in a serious injury or death to the tool operator or to a bystander.

7. Insert another fastener in the

muzzle end of the tool before inserting a new powder load into the chamber. Always insert the

fastener into the tool before inserting the powder load. Keep

your finger off of the trigger until the tool is in position to drive the fastener.

Never carelessly discard or throw unfired powder loads into a trash container.
