Opening And Closing The Housing - Nikon D200 User Manual

4. Opening and closing the housing

The HUGYFOT Nikon D200 housing is opened and closed by means of 2 built-
in countersunk bolts.
This guarantees the safest way of closing. Only
with the right key you can open and close the
housing. A curious 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 with the extended part and
then turned by the shorter part until the shells
are squeezed to one another. Further squeezing
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 blowing it out with com-
pressed 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.
