6.3 Maintenance
Follow these instructions to perform basic maintenance tasks.
6.3.1 Replacing the Main Body Gasket
Check the main body gasket every time a SureCross device is opened.
Replace the gasket when it is damaged, discolored, or showing signs of wear.
The gasket must be:
Fully seated within its channel along the full length of the perimeter, and
Positioned straight within the channel with no twisting, stress, or
stretching.
6.3.2 Replacing the Rotary Dial Access Cover
Check the rotary dial access cover o-ring every time the access cover is removed.
Replace the o-ring when it is damaged, discolored, or showing signs of wear. The o-ring
should be:
Seated firmly against the threads without stretching to fit or without bulging
loosely, and
Pushed against the
flanged cover.
When removing or closing the rotary dial access cover, manually twist the cover into
position. Do not allow cross-threading between the cover and the device's face. After the
cover is in place and manually tightened, use a small screwdriver (no longer than five
inches total length) as a lever to apply enough torque to bring the rotary dial access cover
even with the cover surface.
