2) Place the Laser Toe Gauge on a workbench with the underside of the casting facing up.
3) Loosen the battery cover locking knobs and open the cover.
4) Replace the batteries following the diagram in the battery holder. Flip the switch to ON to be sure the
laser diode operates. Flip the switch to OFF.
5) Close the cover and secure with the battery cover locking knobs.
