3.Slide the spring rail clip (cc) off of the spring rail (dd). Refer to figure 17.
4.Twist and remove the Spring Bumper (ee) and remove the washer (ff) and return spring (gg). Refer to figure 18.
5.Mount the new return spring and washer on to the spring rail (dd). While compressing the spring with the washer near the opposite end of the rail, twist on the new spring bumper until it is past the groove (hh) for the spring rail clip.
6.Mount the new spring rail clip securely and position the bumper against the clip.
7.Repeat steps
NOTE: Check the return of the profile by sliding the profile up the spring rail and letting it go. It should return due to the force from the springs.
8.Slide the return system (bb) back into the unit. It is important to try the alignment of the profile and the flywheel before screwing the return system back on to the unit. This can be done by connecting a battery and pushing then releasing the nose of the unit against a bench or hard surface. This will start the motor spinning.
NOTE: When the profile and the flywheel are correctly aligned, you will hear the motor coast back down from full speed. If the profile and the flywheel are not correctly aligned, the motor it may not start up, may slow down much faster than normal along with a loud grinding noise from the unit. If this happens remove and reseat the return system.
9.Once the return system is correctly seated, open the provided sachet of Loctite®* and apply a small amount on the thread of the two screws (aa) and remount the two screws using the key and tighten securely.
