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.
