33. HANDLING AUTO-GREASING SYSTEM 3. When grease is supplied for the first time, there is usually some air under the follower plate 2 . If grease is supplied to the upper limit, however, the air is bled through the small hole on the side of the tank. When supplying grease next time and there after, stop supplying it when it reaches the bottom of this air bleed hole. 4. After supplying grease, remove the hose fitting and fit the cap to the grease filler of the grease pump without fail. Keep the pump and pail in a clean place. 5-38
