Powers Fasteners PA351 Operating Instructions Manual

2 PA351 MODEL PA351 CAT. NO. 50266/Deluxe Kit PA351 SELECTION GUIDE CAT NO. DESCRIPTION STD CTN. 50266 PA351 Powder Tool Deluxe Kit 1 52133 PA351 Piston 1 Parts are available through customer service @ 914-235-6300 FASTENER FUNCTIONING Prior to learning the safe operating procedures for this tool, it is important to understand how a powder actuated fastener works.A powder actuated fastener is considered to be a direct drive or forced entry type of fastener because it is driven directly into the base material.The driving action causes tremendous forces to be applied to the fastener. Powers powder actuated fasteners are specially designed and manufactured using an austempering process to withstand the forces imposed during the driving operation. Only fasteners manufactured or supplied by Powers Fasteners should be used in this tool. FUNCTIONING IN CONCRETE The performance of a powder actuated fastener when installed into concrete or masonry base materials is based on the following factors: 1. Strength of the base material 2. Hardness and concentration of the aggregate 3. Shank diameter of the fastener 4. Depth of embedment into the base material 5. Fastener spacing and edge distance In addition to these factors, installation tool accessories such as a stop spall which reduces the tendency of the concrete surface to spall during the driving action can increase the performance of the fastener. When a powder actuated fastener is driven into concrete, it displaces the volume of concrete around the embedded area of the fastener shank.As this occurs, the concrete directly surrounding the fastener is compressed and in turn presses back against the shank of the fastener.Additionally, the driving action generates heat which causes particles within the concrete to fuse to the shank of the fastener.This combination of compression and fusion holds the fastener in the concrete base material.A similar action occurs when fastening into block masonry. Generally, the performance of the fastener in a given concrete strength will increase with greater embedment depths in a certain range. Depending on the fastener style and base material strength, embedment depths range from 5/8" to 1-1/2". For depths greater than this range, there is the possibility of fastener bending or fishhooking which may decrease expected load capacities and create a safety hazard. During the driving action, some localized surface spalling of the concrete may occur. Normally, this is a surface effect which does not effect the performance of the fastener. However, it may pose an aesthetic problem for exposed applications where a fixture is not used. In cases such as this, two methods can be used to improve the appearance of the fastening.A stop spall adapter mounted on the powder actuated tool can help to reduce surface spalling.Another method used is to drive the fastener through a steel washer to improve the appearance of the application. FUNCTIONING IN STEEL The load performance of a powder actuated fastener when installed into steel base materials is based on the following factors: 1. Thickness of the steel 2. Tensile strength of the steel 3. Shank diameter of the fastener 4. Depth of point penetration through the steel 5. Fastener spacing and edge distance. When a powder actuated fastener is driven into steel, it displaces the steel laterally 360˚ around the shank of the fastener. Since steel is an elastic material, it presses back against the shank of the fastener to hold it in place.As the diameter of the fastener shank is increased, the load

4 PA351 MODEL PA351 CAT. NO. 50266/Deluxe Kit FASTENER PENETRATION GUIDE The following table lists typical embedment or penetration depths expected in the base materials listed.The penetration will vary depending on the density of the material.This table should be used as a guide since the consistency of these materials varies.When in doubt, a job site performance test should be conducted. DENSITY TYPICAL BASE MATERIAL PENETRATION Soft Masonry Concrete block 1" -1-1/4" Average concrete Poured concrete 3/4" - 1" Dense concrete Pre-stressed/pre-cast concrete 5/8" - 3/4" EDGE DISTANCE Do not fasten closer than 3" from the edge of concrete. If the concrete cracks, the fastener may not hold. Closer edge distances for applications such as sill plates may be permitted if specific fastener testing has been conducted. SPACING Setting fasteners too close together in concrete or masonry can cause cracking. The recommended minimum distance between fasteners is 3" center to center. FASTENER LENGTH SELECTION IN CONCRETE For permanent applications using pins in concrete, first determine the thickness of the fixture to be fastened.To this, add the required embedment or penetration into the base material.This will be the fastener shank length required. For applications in the face shell of masonry block, select a fastener length which will not exceed the thickness of the face shell. For removable applications with threaded studs, the shank length required is equal to the embedment depth required.To determine the minimum threaded length, add the thickness of the fixture and the nut / washer thickness.The nut and washer thickness is equal to the nominal thread diameter. Do not over tighten threaded parts. Maximum tightening torque values are listed in the table below. Use of a nut setter is recommended to reduce the possibility of over tightening the fasteners. For critical applications, perform a job site test. MAXIMUM TORQUE FOR 1/4" STUD (FT.-LBS.) MAXIMUM TORQUE FOR 3/8" STUD (FT.-LBS.) 2 4 INSTALLATION IN STEEL The following guidelines are based on the installation of a fastener in ASTM A 36 structural steel with the point fully penetrating the steel member. Recommended steel material thickness ranges from a minimum of 1/8" to a maximum of 3/8". For use in higher strength structural steel, applications where the point does not penetrate the steel member, or a thickness of steel greater than 3/8", job site performance tests are recommended. BASE MATERIAL THICKNESS Steel base materials should be a minimum of 1/8" in thickness. EDGE DISTANCE For installations in A 36 steel, 1/2" is the recommended minimum edge distance. SPACING The recommended minimum distance between fastenings is 1-1/2" center to center for installations in ASTM A 36 steel. FASTENER LENGTH SELECTION IN STEEL For permanent applications when using pins in steel, first determine the thickness of the fixture to be fastened.To this, add the thickness of the steel base material plus a minimum of 1/4" to allow for proper point penetration.This will be the minimum fastener shank length required. Do not select a fastener length longer than that required for the application.An excessively long shank can burnish or polish the hole created in the steel resulting in a reduction in load capacity. For removable applications with threaded studs, the shank length required is equal to the thickness of the steel base material plus a minimum of 1/4" to allow for proper point 1 2 3 capacity obtained will generally increase provided the steel thickness is sufficient to accept the fastener.To further increase fastener performance in steel, some fasteners have a knurled shank which allows the steel to form a key lock into the grooves to provide higher capacities than those obtained with a smooth shank. For optimum performance, the fastener point should completely penetrate the steel. Normally, a minimum of 1/4" is allowed for the point length.An increase in performance can be expected until the fastener no longer completely penetrates through the steel.At this point, the elastic properties of the steel cause a compression force to be developed at an angle against the fastener point which reduces load capacity. In thicker steel base materials, adequate load capacities may be obtained for applications in which the point of the fastener does not fully penetrate the steel. Job site performance tests are recommended. Fasteners should not be used in areas that have been welded or cut with a torch as these procedures may have caused local hardening of the steel. Over driving of the fastener should be avoided as the rebound created may reduce the load capacity or cause damage to the fastener. When fastening into unsupported long steel members, it may be necessary to provide support in the area of the fastening to prevent spring action which can cause inconsistent penetration and a reduction in load capacity. SUITABLE BASE MATERIAL While powder actuated fasteners can be used successfully in concrete, certain masonry materials, and A 36 steel, some materials are completely unsuitable. Fasteners should never be fired into hard or brittle materials such as cast iron, tile, glass, or rock.These materials can shatter easily resulting in a potential safety hazard. In addition, soft base materials such as wallboard, plaster, or wood are not appropriate as the fastener could pass completely through these materials.The user should never guess when fastening into any base material. Failure to follow the recommended installation and safety guidelines can result in severe injury or death to the tool operator and/or bystanders. CENTER PUNCH TEST A center punch test should always be performed to determine the suitability of the base material for a powder actuated fastening.This test is relatively simple and can help to insure a safe, successful fastening. Be sure to wear the appropriate eye protection when performing this test.To begin, select the fastener to be used for the job.Then, place the point of the fastener against the proposed base material. Strike the fastener with a single hammer blow, then examine the point. If the point of the fastener is not blunted and the base material has a clear point indentation, it is acceptable to proceed with the first test installation. Use of a powder actuated system is not recommended if the following occurs during the center punch test: 1. The fastener point has been blunted.This indicates that the base material is too hard. 2. The base material cracks or shatters.This indicates that the base material is too brittle. 3. When using an average hammer blow, the fastener penetrates the base material easily. This indicates that the base material is too soft. FASTENER INSTALLATION REQUIREMENTS It is important to understand the required minimum base material thickness requirements along with the minimum spacing and edge distance requirements. Failure to follow these requirements can result in an unsuccessful fastening and create a safety hazard. BASE MATERIAL THICKNESS Concrete base material should be at least three (3) times as thick as the fastener embedment penetration. If the concrete is too thin, the compressive forces forming at the fasteners point can cause the free face of the concrete to break away.This can create a dangerous condition from flying concrete and/or the fastener and also results in a reduction of fastener holding power. For applications in the face shell of concrete masonry block, select a fastener length which will not exceed the thickness of the face shell.

It is your responsibility to obtain proper training and a Powers Fasteners operator card prior to using this tool in compliance with the current American National Standard A10.3 Safety Requirements for Powder Actuated Fastening Systems and the Federal Occupational Safety and Health Administration Standards (OSHA). Existing state or local regulations should also be followed.When using this tool, you must have the qualified operators card in your possession. Revocation of card - Failure to comply with any of the rules and regulations for safe operation of powder actuated tools shall be cause for the immediate revocation of your qualified operator card. The following is a summary of safety precautions to be followed when operating a Powers Fasteners powder actuated tool. Failure to follow these safety instructions can result in serious injury or death to operators or bystanders. PRIOR TO OPERATING THE TOOL 1. Warning signs should always be posted within the area in which a powder actuated tool is to be used.These signs should be at least 8" x 10" in size with boldface type that is not less than 1" in height.The sign should state “Powder Actuated Tool In Use". 2. Approved safety goggles should always be worn by operator or bystander, to protect their eyes from flying particles. Hearing protection should always be worn by the operator and bystanders when using a powder actuated tool. Other personal safety protection as required should also be used. 3. Never modify or fabricate parts for use in your Powers tool. Use only Powers fasteners, loads, and tool parts. 4. Hands or other body parts must never be placed in front of muzzle/barrel.Accidental discharge can cause piston and/or fastener to pass through the operator’s hand. 5. Never compress the tool against any part of the body. Serious injury or death may result in the event of an accidental discharge. 6. Always point tool in a safe direction at all times. 7. Use the tool for its intended purpose only. PREPARATION FOR LOADING THE TOOL 1. Tools must be checked prior to operating to make sure they are not fully or partially loaded with a powder load or fastener. 2. To insure safe operation, perform the daily function test described in this manual. Be sure the tool is not loaded prior to performing this test. 3. Do not operate this tool unless all its parts are in place and operating appropriately. Never attempt to use a malfunctioning tool. Call 1-800-524-3244 for assistance. 4. Never guess about the suitability of a base material. If you are uncertain about the suitability of a base material, perform a center punch test. 5. Do not operate the tool until you learn and understand the color code / numbering system used to identify the power level of powder loads. OPERATING THE TOOL 1. Only use fasteners and powder loads designed for this tool as supplied by Powers Fasteners. 2. Do not use powder actuated tools in a flammable or an explosive atmosphere. 3. Do not fire a tool without a fastener.The piston will impact the work surface possibly causing serious injury to the operator or bystanders along with damage to the tool. 4. Do not load the tool until you are ready to make a fastening. Check the power load level before inserting it into the tool chamber. 5. Fastener must be loaded prior to loading the powder load, to prevent injury to operator or bystander in the event of an accidental discharge. 6. Do not close tool against work surface.The tool should be manually closed, with hand away from muzzle/barrel to prevent accidental discharge. 7. Hold the tool perpendicular to the work surface at all times. Use a spall guard wherever possible.This will limit the possibility of fastener ricochet which could cause serious injury or death to the operator or bystanders. 8. Always perform a test fastening with the lightest load level designed for use in the tool. If the lightest load fails to set the fastener, try the next highest load until the proper level is attained. Failure to follow this procedure may cause the fastener to be overpowered. If this occurs, the fastener may fully penetrate the base material causing serious injury or death to someone. Overpowering the fastener can also damage the tool, creating a safety hazard to both the operator or bystanders. 9. Do not fasten into cast iron, tile, glass, or other types of brittle materials.These materials can shatter and create sharp fragments which may cause injury. 10. Do not fire tool within 3" (three inches) of the edge of a concrete base material or within 1/2" (one-half inch) of the edge of a steel base material. 11. Do not attempt to install a fastener closer than 3" (three inches) to another previously inserted fastener in concrete or 1-1/2" (one and one-half inch) in steel. 12. Do not fasten into a concrete base material less than 3 times as thick as the fastener penetration or into a steel base material thinner than 1/8". 13. Never attempt to install a fastener in a cracked or spalled area in concrete. Place fastener at least 3" (three inches) away from a spalled area to prevent the possibility of the fastener bending and striking an operator or bystander. 14. Do not attempt to install fasteners in areas that have been welded or cut with a torch as these procedures may have caused local hardening of the steel. 15. Do not fasten through a predrilled hole unless proper guidance is provided. 16. If you decide not to make a fastening after the tool has been loaded, you must always remove the powder load first followed by the fastener. 17. Never attempt to override the safety features of this tool. HANDLING THE TOOL AND POWDER LOADS 1. Never leave a loaded tool unattended. Once the tool is loaded, make the fastening immediately or unload the tool. 2. Always unload the tool before work breaks, changing parts, cleaning or servicing, and when storing. 3. To prevent accidental discharge of loads, never carry the powder loads in the same container as the fasteners or other hard objects. 4. Always store the powder loads in the containers provided or in an enclosure provided for them. Never intermix the various power levels. Keep them segregated in clearly identified containers. 5. Powder loads should never be used in firearms.They are normally more powerful that the cartridges supplied with the firearms. 6. Powder actuated tools and powder loads should always be stored under lock and key.Tools must be unloaded when not in use. TOOL MALFUNCTION 1. In the event that a load fails to discharge after the trigger is pulled, the tool must be kept depressed against the work surface for a minimum of 30 (thirty) seconds in case of a delayed load discharge.Then carefully remove the entire load strip. and dispose of it in a can of water or other nonflammable liquid. Never attempt to force or pry a load out of a tool chamber. 2. Never discard unfired powder loads into a trash container. 3. Do not attempt to unload or disassemble a jammed, stuck or broken tool as improper handling may cause it to discharge and strike operator and/or bystander. A jammed tool must be pointed in a safe direction at all times.Tag the tool and lock it up. Call your Powers Fasteners representative for proper assistance.
