Special care must be taken to insure that part is not damaged during the installation process. Pull plunger to full extension, apply lubricant to plunger. Push switch in and seat into opening, pressing against pedal. Once seated, secure switch by rotating to the right approximately 45 degrees. This action turns the plunger shoe to the correct angle to make the contacts operate properly.
