Assembling
Place the positive and negative groups upside down with posts through holes in bench and slide in separators. The wood and rubber separators are inserted as follows: The rubber separator is placed against the grooved side of the wood separator, and the two are then slipped between the negative and positive plates with the rubber separator next to the positive plate. (See Fig. 311.)
Inserting Locking Pin
A rubber bumper is pinned on one end of the lock pin by means of a lead pin, and the lock pin is then slipped into place with the lock pin insulating washer placed between the outside negative plates and the wood separators. (See Fig. 312.)
A rubber bumper is then slipped over the other end of the lock pin and secured by a lead pin.
Place element on wooden blocks and fasten cover, as shown in Fig. 313.
Sealing Covers
Be sure all old sealing compound and traces of electrolyte are removed from the cover. Heat sealing compound until it can be handled like putty, roll out into a strip about 1/2 inch in diameter, place strip of compound around inside edge of cover (Fig. 314) and heat to melting point with blow-torch. The top of jar should also be heated to insure a tight seal. Compound can be melted in a suitable vessel and a 1/2 inch strip poured around cover.
