# S/R: Short Reach Mandrel. See page 17 and 18 for explanation.
M A N D R E L S & M A N D R E L F O L L O W E R S P R I N G S
Mandrels and mandrel follower springs, illustrated on page 9 need to be selected to suit the fastener type and size as well as the size
of the hole in the application. Use of the wrong mandrel could increase the risk of breakage and the wear of the mandrel head. Feeding
problems could occur if the wrong mandrel follower spring is used.

READ THE SAFETY INSTRUCTIONS on pages 2 and 3 carefully.
While a small amount of wear and marking will naturally occur through normal and correct use of mandrels, they must be
regularly examined for excessive wear and marking, with particular attention to the head diameter, the tail jaw gripping
area of the shank or heavy pitting of the shank and any mandrel distortion. Mandrels which fail during use could forcibly
exit the tool. 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.
For mandrel or mandrel follower spring selection, follow instructions on page 20.
