How to Apply Grease to the O-ring 1 Apply only Olympus exclusive lubricant to each O-ring. 2 Spread the lubricant onto the entire circumference of the O-ring. 3 Check that the O-ring is free of scratches or unevenness. Make sure that your fingers and the O-ring are free of dirt, and squeeze about 5 mm of lubricant onto a finger. (5 mm is the most appropriate amount.) Spread the grease onto the entire circumference of the O-ring using 3 fingers. Be careful not to use excessive force as this may stretch the O-ring. After spreading the lubricant, check visually and by touch that the O-ring is not scratched and that its surface is flat. If it is damaged in any way, replace it with a brand-new O-ring. 4 Apply lubricant on the O-ring contact surface. Use the lubricant remaining on the fingers to clean and lubricate the case's contact surface. CAUTION: • Always perform maintenance of the waterproof function even when the Case has been opened every shooting. Neglecting this maintenance may become the cause of water leakage. • When the Case is not to be used for a long time, remove the O-ring from the groove to prevent deformation of the O-ring, apply a thin coat of silicone grease, and store it in a clean plastic bag or the like.
