4. Opening and closing the housing
The HUGYFOT Nikon D90 housing is opened and closed by means of 2 built-in
countersunk bolts.
This guarantees the safest way of clo-
sing. Only with the right key you can
open and close the housing. A curi-
ous buddy cannot open the housing
by accident. Herewith we exclude the
unwanted opening of the housing. To
seal the housing, the socket screw key
is inserted into the countersunk bolt
and then turned until the shells are
squeezed to one another. Stop turning the key when resistance increases
significantly. Further turning the screws hasn't got any sense and can only
damage the thread. At a depth of 6 meters the hydrostatic pressure takes
over and keeps all the o-rings under pressure. Always check the tension on
the bolts before diving if the housing wasn't opened in between two dives.
First maintenance command:
The screws, and more specific the tread, must be kept very clean at all times.
The main o-ring merely lies in the o-ring groove. It can be removed by blow-
ing it out with compressed air, by using a credit card or by rubbing two pieces
of paper towards each other against the o-ring so the o-ring pops out of his
groove. Never use a metal object or any other hard material: by doing this you
can DAMAGE the O-ring and the groove.
Second maintenance command:
Whenever the o-ring is dirty or misted up, it must be removed from its
groove (see first command) and cleaned up with soap (do not use corrosive
or chemical degreasers). Afterwards clean it with clear water.
O-rings have to be dried up with a clean cloth (do not squeeze) or by air.
Grease the O-rings (except the main red o-ring) by using HUGYFOT grease.
Pull the o-ring gently through your fingers without stretching it! O-ring
grooves, housing and shell edges have to be cleaned with a clean cloth.
