he lead sealing nuts with graphite that has been
mixed to a paste with water. Do not use grease or vaseline to
lubricate these nuts. Then put on the sealing nuts and tighten them
partly with your fingers.

You are now ready to insert the separators as directed on page 361.
Types MHA, PHC, KXD, KZ, LXR, LXRE, LXRV, XX, and XXV have, in
addition to the usual wooden separators, perforated rubber sheets,
which should be placed against the grooved side of each wooden
separator before inserting, and insert with rubber sheet against the
positives.

Make a careful examination to see that you have not left out any
separators.

When the separators are all in place, even them up on each side. Then
tighten the sealing nuts with the special Exide wrench. When you have
turned the nuts down tight, lock them in place by driving a center
punch on the threads on the post just above the nut, Fig. 241. This
will damage the thread and prevent the nut from turning loose.

Putting Plates In Jars

The next step is to lower the plates into the jars, as described on
page 362. In types KXD, LXRE, and XE be sure to first replace the two
soft rubber buffers in the bottom of the jar, one over each ridge.

Filling Jars With Electrolyte

As soon as you have an element in place in the jar, fill the jar with
electrolyte of the proper strength, as described on page 364, to
prevent the separators and plates from drying. The negatives,
especially, must be covered with electrolyte to prevent them from
heating and drying.

Sealing Exide Battery Covers

For Types DX, LX, LXR, LXRV, PHC, XC, XX, and XXV, which have the
single flange type of cover, slowly heat the sealing compound until it
runs, but do not get it so thin that it will run down into the cell
between the cover and jar. Then pour it into the channel between cover
and jar walls. Allow it to cool and finish it off flush with a hot
knife. When pouring, be sure the compound is liquid and not lumpy, as
in such a case a poor seal will result. A glossy, finished appearance
may be given to the compound by passing a flame over it after the job
is finished.

For Types KXD, KZ, LXRE, MHA, and XE, which have the double flange
type of cover, have ready a string or worm of sealing compound about
3-16 inch in diameter, made by rolling between boards some of the
special compound furnishe
