Readjusting the venting lever

If, despite the venting lever being closed (see chapter 10.3.2, Fig. 10.2, pos. 4), product
escapes out of the return line, the venting lever must be readjusted.
To do so, proceed as follows:
Turn venting lever by 60° left (Fig. 10.4) and pull off.
Plug in venting lever on left stop position and turn right until there is no metering product
(Fig. 10.6) escaping from the venting line.
Pull off venting lever and push it back on 60° position (Fig. 10.4).
Close venting lever (turn right with the arrow in the 'up' metering direction) (Fig. 10.6).
Check for leaks in venting position (venting lever in left stop position).
If it is impossible to close the venting lever, or only possible with great force, proceed
as follows:
Pull off venting lever as in Fig. 10.4.
Turned approx. 15° to the right, push it back on.
Close venting lever (turn right with the arrow in the 'up' metering direction).
Check for leaks in operating position (Fig. 10.5).
