For cold start press the rubber ball/valve 4-5 times at the bottom for ink flow at the tip. Mark vertically at 90-degree angle & ensure the ball presses the surface for smooth ink flow. As pressure reduces, press the rubber valve 2-3 times to continue writing. Do not press the rubber bulb when not in use as it will lead to increase ink pressure.
