To remove the arm and blade assembly, raise the blade end of the arm off of the windshield and move the slide latch away from the pivot shaft. The wiper arm can now be removed from the shaft without the use of any tools. To install, push the main head over the pivot shaft. Be sure the wipers are in the parked position, and the blade assembly is in its correct position. Hold the main arm head onto the pivot shaft while raising the blade end of the wiper arm and push the slide latch into the lock under the pivot shaft head. Then, lower the blade to the windshield. If the blade does not lower to the windshield, the slide latch is not completely in place.
