HES 412 RIVET NUT RATCHET INFORMATION 12 6522 Guarantee. For this Wurth machine, we provide a 6-month guarantee against material and workmanship defects from the date of purchase (verified by invoice or delivery document). Damage that has occurred will be corrected by replacement or repair. Damage caused by normal wear, overloading or improper handling is excluded from the guarantee. Claims can only be accepted, the tool must be sent assembled and untouch to a Wurth branch office, your Wurth sales representative or a customer service agent authorised by Wurth. When selecting the rivet nut/bolt to be set, ensure that the required grip range is met in respect to the workpiece. Otherwise proper seating cannot be guaranteed. 1. Inserting the mandrel 6 Slide the matching nose piece 1 together with the lock nut 2 over the thread of the mandrel and screw together in the housing (Fig. A ). 2. Starting position of the HES 412 Set the toggle switch 4 to position 1. If the scale 5 is not in the zero position, turn the lever in clockwise direction and set the scale 5 to zero. Ensure that the two levers of the tool are parallel to each other (Fig. B ). 3. Loading a rivet nut/bolt Fully screw a rivet nut/bolt onto the mandrel 6 . The first thread (X) of the mandrel must be visable at the front edge of the rivet nut. Lock the nose piece 1 with the lock nut 2 . 4. Determining the stroke The correct stroke is best determined by trial on a test-workpiece and reading the scale. The stroke must be set to zero again after each riveting process, whereby the stroke determined in trial can be used as the working stroke. The stroke results from the maximum grip range (Y) of the rivet nut/bolt, minus the material thickness (Z) of the workpiece. The maximum grip range of the rivet nut/ bolt can be referred to in the product information of the respective rivet nut/bolt. Operation.
