3.10 AGSS Inspection
3.10.1 Check the Float
Install the AGSS. Check if the float floats off and exceeds the MIN level. If the float is tacky
or damaged, re-install the AGSS or replace the float.
NOTE
z Do not block the AGSS pressure compensation openings during the inspection.
If the float fails to float off, the possible reasons are:
1. The float is tacky or stuck to the guide bar. Invert the AGSS and check if the float
moves up and down freely. If not, clean where the float and guide bar meet to remove
possible foreign substance. Replace the float or guide bar when necessary.
2. The filter screen inside the top cove may be occluded. Remove the filter screen as
described below and check if the filter screen is occluded.
a.Turn the top cover counterclockwise to separate it from the sight glass.
