To ensure safe operation −
Diesel fuel is extremely flammable
a n d e x p l o s i v e u n d e r c e r t a i n
conditions. Refuel in a well ventilated
area with the engine stopped.
Keep away from cigarette, smoke and
sparks when refueling the generator.
Always refuel in a well-ventilated
location.
Wipe up spilled diesel fuel at once.
Connections for standby power to a building's
electrical system must be made by a qualified
electrician and must comply with all
applicable laws and electrical codes. Improper
connections can allow electrical current from
the generator to back feed into the utility lines.
Such back feed may electrocute utility
company workers or others who contact the
lines during a power outage, and when utility
power is restored, the generator may explode,
burn, or cause fires in the building's electrical
system.
