CHECKING THE O‐RING
1. Prior to each closure of the housing, the back door black O‐ring should be visually inspected. If there

a. Insert the O‐ring remover between the black O‐ring and the groove it is
seated in (image #21).
b. Slip the tip of the inserted
O‐ring remover below the
black O‐ring, while making
sure the O‐ring doesn't get
damaged (image #22).
c. Carefully hold the O‐ring
with your fingertips in order
to remove it from the
groove.
