2 Study these SAFETY RULES carefully before install- ing, operating or servicing this equipment. Become familiar with this manual and with the unit. The gen- erator can operate safely , efficiently and reliably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fundamental rules or p[...]

3 • Before performing any maintenance on the gen- erator , disconnect its battery cables to prevent accidental start up. Disconnect the cable from the battery post indicated by a NEGA TIVE, NEG or (–) first. Reconnect that cable last. • Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and[...]
