HOW TO HANDLE AN ANODE-CAP

Do not use sharp objects which may cause damage to the sur- face of the anode-cap.

Do not squeeze the rubber covering too hard to avoid damag- ing the anode-cap. A material fitting called a shatter-hook ter- minal is built into the rubber.

Do not force turn the foot of the rubber cover. This may cause the shatter-hook terminal to protrude and damage the rubber.

When one side of the rubber cap sepa- rates from the anode button, the anode- cap can be removed by turning the rub- ber cap and pulling it in the direction of arrow .
