Battery short circuitsDisconnect the battery before generator set installation or maintenance. Remove all jewelry before servicing the equipment. Use tools with insulated handles. Remove the negative (--) lead first when disconnecting the battery. Reconnect the negative (--) lead last when reconnecting the battery.
Gas fuel leaksCheck the LPG vapor or natural gas fuel system for leakage by using a soap and water solution with the fuel system test pressurized to 6--8 ounces per square inch (10--14 inches water column). Do not use a soap solution containing either ammonia or chlorine because both prevent bubble formation. A successful test depends on the ability of the solution to bubble.
