Activity Overview / Details


Powder Actuated Fasteners




No one should attempt to operate a Ramset TM Fastening Tool before reading the instruction manual. Careful study of the instructions for loading, firing and maintenance of the tool will enable you to obtain the best performance.

Every operator must be fully conversant with the Local or State Government Regulations governing the use of Powder-actuated (P.A.) Fastening Tools, in addition to holding the appropriate Accredited Operators Certificate where required. Ramset recommends instruction for all users of Ramset TM P.A. Fastening Tools.

To promote safe working conditions, the following safety precautions should be observed in the use of P.A. Fastening Tools.


1. NEVER attempt to use your Ramset PA tool UNLESS you have satisfactorily completed authorized training and read the Instruction Manual.

2. When not in use, the PA Tool should be placed, unloaded, in its box or case, which should then be shut, locked and stored in a safe place to which only authorized persons have access.

3. ALWAYS follow the directions for care of the tool contained in this book. Special adaptors shall be fitted and used strictly in accordance with the instructions and in a manner such that the safety features of the tool are not adversely affected.

4. ALWAYS display a suitable Authorized Warning Notice in such a manner as to be clearly visible to all persons who are at, or near, the place where a tool is being used. Such notice shall be in accordance with local Government Regulations.

5. NEVER fire the tool UNLESS you and any other people in the area are wearing safety eye and hearing protection.

6. NEVER let bystanders gather around when you are using a PA Tool.

7. NEVER use a powder-actuated tool in the presence of any explosive or inflammable gas, dust or vapour, in an atmosphere which is compressed, or in any place where the power load may be unintentionally exploded or be rendered dangerous by the presence of heat.

8. NEVER leave a tool unattended in a place where it would be available to unauthorized persons.

9. NEVER load the tool until ready to fasten. The tool should not be loaded until immediately prior to its use. If it has been loaded but not put into immediate operation, it should be unloaded and not laid down or carried around in the loaded condition. Never load the tool at other than the place at which it is to be used, thus minimizing risk of unintentional firing.

10. NEVER carry fasteners or other metal objects in the same pocket or package as power loads.

11. ALWAYS check that the barrel is free from obstructions before loading.

12. NEVER point the barrel of a loaded or unloaded tool towards any person. ALWAYS point the tool downwards and as far as practical away from the operator's body. This applies in particular where a power load that has misfired is being removed.

13. NEVER place your hand over the muzzle with a power load in the tool.

14.Fasteners should not be driven into brick, concrete, or similar substances if:

a) nearer than 75mm to an edge or

b) the thickness of which is less than 100mm, or less than three times the shank penetration into the basic material, whichever is the lesser, or

c) nearer than 150mm to where a former fastener has failed.

15. Fasteners should not be driven into steel if; a. less than 4mm thick, unless, for fastening into thinner steel, the shank diameter of the fastener is less than the thickness of the steel or b. nearer than 12mm to an edge or hole.

16. NEVER fasten into wood, fibreboard, plaster or other soft materials unless backed up by a material that will prevent the fastener from passing completely through. (Masonry or thick steel).

17. NEVER fire fasteners into brittle or hard materials such as glazed brick or tile, terracotta, marble, granite, slate, glass or into hard steel. Do not attempt to fasten into high tensile steel, case iron, heat treated steel or pressurized vessels such as gas bottles, compressed air cylinders etc.

18. NEVER attempt to fasten into a spalled area in masonry where a previous fastener has failed.

19. Fasteners shall not be driven through existing holes unless the tool is specifically equipped by Ramset TM for accurate alignment of the barrel.

20. DO NOT fire into material which dulls the point of a test fastener, when first tried by hand as a center punch.

21. ALWAYS position your body comfortably in line with and behind the tool.

22. ALWAYS make certain the tool is at right angles (90°) in both directions to the work surface before firing.

23. NEVER fire tool at an angle to the work surface.

24. NEVER use the tool at or near the extremities of your reach.

25. IF A LOADED TOOL JAMS in the firing position, it should be locked in a secure place where no harm could result if it accidentally discharged. DO NOT attempt to make any adjustments to the tool.  Call your Ramset TM representative or supplier.

26. IF A MISFIRE OCCURS, the tool should be kept firmly against the worksurface for a short time. Refer to the local PA Tool Regulations for the minimum delay time (Aust./NZ/SE Asia 10 secs/ UK 30 secs.)

27. NEVER use Ramset TM Power Loads in firearms. They are much more powerful than ordinary ammunition and must be used only in powder-actuated tools.

28. ALWAYS wear safety eye and hearing protection when using a PA Tool.
