In the following step, do not point gun at yourself. If necessary, use a mirror to verify purge rod travel. Pointing gun at yourself or someone else can lead to accidentally spraying yourself or someone else with fluid. If the purge rod was not correctly installed, purge rod can shoot out of the barrel when gun is actuated and can cause severe injury.
