    ARE SHARP EDGES OR CORNERS ON THE APPLICATION. THE OPERATING PRESSURE SHALL NOT EXCEED 8 BAR - 120 LBF/IN BENCH MOUNTED TOOLS MUST NOT BE USED WITHOUT AN AVDEL GUARD AND WITH THE SHIELD IN POSITION ABOVE THE TOOL BARREL AND THEY SHOULD NOT BE OPERATED IF THE GUARD IS DAMAGED IN ANY WAY.
  • Page 6 There are two models: the 07271 and 07274 are hand-held and can be suspended vertically through a ring at the rear of the tool. Both models will place most repetition fasteners, as shown on the tables below.

  • Page 7: Tool Capability

    07271 AND 07274 MODELS These are hand held models which can be suspended vertically from a ring mounted at the rear of the tool. While the 07274 is less powerful with only two pistons, (see differences on the general assembly, page 25), it gives greater access with its longer barrel protusion.

  • Page 8: Air Supply

    To ensure maximum tool life and minimum tool maintenance, these should be fitted within 3 metres of the air inlet point on the tool itself for the 07271 and 07274 models, see diagram below.

  • Page 9: Bush Stops

    B U S H S T O P S I M P O R T A N T Bush stops are fitted to reduce the stroke length of the tool thus the tool cycle time and shock loads. Minimising shock loads will increase the efficiency of the tool and will prolong the life of the mandrel.

    Release the trigger. The next fastener will automatically be presented through the nose jaws, ready for placing. A C C E S S O R I E S This accessory is designed to be fitted to the 07271 and 07274 tools only when placing Avserts. It enables the application to be held square to the Avsert during the placing sequence.
  • Page 13 O S E E Q U I P M E N T On speed riveting tools such as the 0727 type, the nose equipment always consists of three elements; a nose jaw, a mandrel and a follower spring. All three items are matched to the fastener being placed and to the hole size in the application. I M P O R T A N T To avoid complete dismantling of the tool it is essential to check the orientation of the cursor before fitting the nose equipment to the tool.

  • Page 17 It is the customer’s responsibility to ensure that mandrels are replaced before any excessive levels of wear and always before the maximum recommended number of placings. Contact your Avdel representative who will let you know what that figure is by measuring the broach load of your application with our calibrated measuring tool. These tools can also be purchased under part number 07900-09080, supplied with all necessary information for testing.
  • Page 18 Tables below left and right and over the next 4 pages list part numbers of all mandrels and mandrel follower springs available per fastener or group of fasteners, i.e. for Chobert and Grovit on these pages. While fastener sizes are always shown in their specified units, each table has been produced twice to offer dimensions in imperial units on the left-hand page then in metric units on the right-hand page.
