2. Detach the index cover from the meter by removing the four screws holding it in
place.
3. Examine the index cover screws you removed. Verify they are 5/8-inch long and not
corroded.
If the screws are 5/8-inch long, and are not corroded, retain for later use.
If the screws are an incorrect length or corroded, dispose of them properly. Use
1/4 - 20 x 5/8-inch screws as described in
Replacement Screws on page 10.
TIP You can use the index cover you just removed as a temporary storage
location for screws.
NOTE Dispose of the index cover properly when finished with the installation
procedure. Do not leave it on customer premises.
4. Unscrew one index mounting screw completely.
Hold one hand beneath the index to catch the screw when it falls out of the index
assembly. If it does not fall out by itself, be sure to remove it.
