Safety Rules SAVE THESE INSTRUCTIONS – This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. The manufacturer suggests that these rules for safe operation be copied and posted in potential hazard areas. Safety should be stressed to all operators and potential operators of this equipment. - Page 5 Safety Rules EXPLOSION HAZARDS • In case of accident caused by electric shock, immediately shut down the source of electrical power. If this is not pos- • Do not smoke around the generator(s). Wipe up any fuel or sible, attempt to free the victim from the live conductor. AVOID oil spills immediately.
