OPERATION All tool operators manuals shall address all topics in Section 7. 7.1 In selecting the proper power setting for an application, it is important t

30、o start with the lowest power setting. This includes selecting a powder load with the lowest power level recommended for the tool being used, and adjusting the tool power to its lowest setting for tools so equipped. If the first test fastener does not penetrate to the desired depth, the next higher

31、power setting should be used as follows: 7.1.1 For tools equipped with an adjust-able power regulation feature, increase the power setting of the tool. If the test fastener still does not penetrate to the desired depth, select the next most powerful powder load (see Table 1). 7.1.2 For tools not equ

32、ipped with an adjustable power regulation feature, select the next most powerful powder load (see Table 1). 7.2 Only qualified operators shall operate tools. A qualified operator is one trained in accordance with Section 11 and/or 12. 7.3 Tools shall be stored, operated and maintained in strict acco

33、rdance with the manufacturers instructions. 7.4 Eye protection complying with ANSI/ISEA Z87.1 shall be worn by opera-tors, assistants and adjacent personnel at all times when the tool is in use or when fasteners are being driven. Hearing protec-tion complying with ANSI/ASSE A10.46 shall be worn as r

34、equired by the manu-facturer and in accordance with OSHA 29 CFR 1910.95 and 29 CFR 1926.52 and 1926.101. Appropriate respiratory protection shall be worn as necessary to meet OSHA requirements for respiratory lead exposure, as applicable. 7.5 Prior to use, the operator shall inspect the tool to dete

35、rmine that it is in proper working condition in accordance with the testing methods recommended by the manufacturer of the tool. 7.6 Any tool found not to be in proper working condition shall be immediately removed from service and tagged: DEFECTIVE: DO NOT USE It shall not be used until it has been

36、 properly repaired in accordance with the manu-facturers instructions. 7.7 The proper shield, fixture, adapter or accessory suited for the application, as recommended and supplied by the manu-facturer, shall be used. 7.8 Only those types of fasteners and powder loads recommended by the tool manufact

37、urer for a particular tool, or those providing the same level of safety and performance, shall be used. 7.9 Before fastening into any question-able material, the operator shall check to see if it is suitable by using the center punch test. Using a fastener as a center punch, try to drive it into the

38、 material using a standard hammer blow (wear eye protection). The material is not suitable if the: 1) Fastener point is flattened (the material is too hard); 2) Fastener penetrates the mater-ial easily (the material is too soft); or 3) Material cracks or shatters (the material is too brittle). AMERI

39、CAN NATIONAL STANDARD A10.3 2013 16 If the fastener makes a small indentation without deforming the fastener, the base material is suitable. 7.10 No tool shall be loaded unless it is being prepared for immediate use.
