The Spiral Cam seated in the Cast Base Plate requires the application of grease into its pocket. To access, the Jaws must be open.
Place the Lock Bar in its fully extended position and retain by seating the Flip Lock in its Uncoupling position. Insert the Safety Lynch
Pin. Using a suitable probe, apply grease to the pocket under the Spiral Cam. When complete, remove the Safety Lynch Pin, rotate the
Flip Lock from its seat and allow the Lock Bar to retract inward into the coupling position.
