Mandrels and mandrel follower springs, illustrated on page 12 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.

For mandrel or mandrel follower spring selection, follow instructions on page 19.

READ THE SAFETY INSTRUCTIONS  page 4 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.
