3. Overview, functional description 3. Overview, functional description Overview Fig. 1 1 Reservoir The reservoir with a follower piston resting on the lubricant stores the lubricant. 1.1 Reservoir venting device The reservoir vent (1.1) is positioned on the reservoir. It provides air for the reservoir while the pump is operating and consuming lubri- cant and vents the reservoir when it is filled with lubricant. - Page 26 3. Overview, functional description Overview Fig. 2 5 Vent screw Serves to vent the lubricant. To do so, after filling the reservoir the vent screw (5) must be loosened there leaks a small amount of lubri- cant. Then firmly tighten the vent screw again. 6 Filler fitting The filler fitting serves to fill the reservoir via a transfer pump.
