The cumulative reserve fund for equipment purchase shall be used only as a reserve fund for the accumulation of moneys with which to carry out the purposes of the fund and shall own no equipment as such. All equipment purchased by the fund from accumulated reserves on behalf of any department, office or fund, including the equipment rental fund, shall immediately be transferred to and become the property of the proper department, office or fund for which the purchase was made. In order to facilitate the trade-in or exchange of old equipment in the purchase of new equipment, the old equipment may be transferred to the cumulative reserve fund for equipment purchase to be sold or otherwise used in the purchase of new equipment. (Ord. 399 § 6, 1966).
