INSPECTION/SETUP
CIRCUIT BREAKERS
To protect the generator from an overload, a 3-pole, 90 
amp, main circuit breaker is provided to protect the U,O 
and V Output Terminals from overload. In addition two 
single-pole, 20 amp GFCI circuit breakers are provided to 
protect the GFCI receptacles from overload. Two 50 amp

FUEL CHECK
Refi lling the Fuel System
This generator has an internal fuel tank located inside 
the trailer frame and may also be equipped with an 
environmental fuel tank (Figure 18). ALWAYS fi ll the fuel 
tanks with clean fresh #2 diesel fuel. DO NOT fi ll the fuel 
tanks beyond their capacities.
Pay attention to the fuel tank capacity when replenishing 
fuel. The fuel tank cap must be closed tightly after fi lling. 
Handle fuel in a safety container. If the container does not 
have a spout, use a funnel. Wipe up any spilled fuel 
immediately.

DANGER
Fuel spillage on a hot engine can cause 
a fi re or explosion. If fuel spillage occurs, 
wipe up the spilled fuel completely to 
prevent fire hazards. NEVER smoke 
around or near the generator.
CAUTION
ONLY properly trained personnel who have read 
and understand this section should refi ll the fuel tank 
system.
