turning the screw once fully unscrewed as it will damage the thread in the plastic boss.

Refitting the case back
These indicators are often used in very harsh environmental conditions. Correct installation of the case back, o-ring,
and screws is essential to help maintain an effective environmental seal for the case. Incorrect installation can lead
to case leaks and serious malfunctions.
•
Ensure that the cleaned screw fits the old thread when tightening. First turn the screw anti-clockwise until it
drops into place before tightening.
•
Ensure that the case sealing o-ring is in place and does not get pinched between the case halves. It is highly
recommended to replace the o-ring with a new one. The case back screws are an integral part of the sealing of
the case. If any of the screw threads are stripped for any reason, the case front must be replaced.
1
Inspect the 12 screws and replace any that are damaged.
2
Remove any plastic swarf from the screw bosses, the screws, in the case, and around the case o-ring.
