To install the replacement washer on your MI-6 or MI-4 pinpointer, ensure the washer sits flat in the battery compartment seal area with no twists or folds. The rubber washer creates a waterproof barrier when properly positioned between the housing and end cap. Avoid overtightening the end cap, as this can crush the washer and shorten its lifespan. Hand-tight installation is typically sufficient for a proper seal. After installation, verify the seal is functioning correctly before using the pinpointer in wet conditions to ensure moisture protection.
