and with one foot pressed against the side of the case.
If you do not wish to remove the complete cells, or should the jars
fit too tight in the case, unseal the covers and remove the plates
according to the instructions given on page 333.
Types KZ and MHA. These batteries have the double flanged cover.
Several methods may be used in removing the plates from the jars. In
each case, the top of the cell is cleaned, gas blown out of the vent
holes, and the sealing nuts removed before opening the cells.
[Fig. 240 Removing double flange exide cover]
First, a flame may be used to soften the sealing compound which is
placed in the slot formed by the two flanges of the cover. If you wish
to use a flame, first remove each complete cell from the case,
loosening the tie bolts that pass through the case to release the
jars. Then hit out each complete cell. Now get two strong boards which
are about one fourth inch longer than the height of the jar. See Fig.
240. Support the jar on these boards by resting the lower edge of the
sides of the cover on the top edge of the boards. Then run a moderate
flame around the outside of the flange until the cover is soft, and
the compound melting. Then press down on the cell posts with your
thumbs, and the jar and plates will drop free of the cover. The
plates are then drawn out and rested on the top of the jars to drain,
as usual.
Another method is to remove the cells from the case and put them in
the battery steamer for ten minutes as described on page 332. Instead
of first taking the complete cells out of the case and then steaming
them separately, you may steam the entire battery for about ten
minutes, and then draw out the plates and cover of each cell with gas
pliers without removing the jars. This method must be used in opening
types KXD, LXRE, and XE, which have sealing compound under the jars.
Work on Plates, Separators, Jars, and Case
Having opened the battery, follow the instructions given on pages 335
to 361 for examination of plates and separators, and all work on
plates, jars, separators, and case.
Reassembling Plates
[Fig. 241 Upsetting threads to prevent nut from turning]
First slip the positive and negative groups together without
separators. Then wipe the posts with a rag moistened with ammonia,
rinse them with water, and dry thoroughly with a clean rag. Next slip
the soft rubber washers over the posts and place the cover in
position. Lubricate t
