The SL- and BL-series of Mining and Tunnel Lasers is a self-contained apparatus powered by a non-rechargeable battery pack consisting of alkaline cells in either AA-size, C-size or D-size options. Various configuration options allow the lasers to be used with removable or non-removable battery packs. In laser configurations fitted with non-removable battery packs, power to the laser circuitry is limited by a fuse located in the laser head. In removable battery pack configurations, the fuse is located in the battery pack. Fuses are not replaceable by the user.Refer Annex for equipment configuration.
