NOTE
The generator set can be operated continuously at anyload from no load up to and
including rated load; However, at light loads (less than 25% of set rating) an oily residue
(unburned fuel oil) may occasionally be noticed in the exhaust system outlet and around
connection joints in the exhaust system. This residue is caused by the inability of the
fuel injection system to consistently meter the small amount of fuel required to operate at
these low load levels and is not a defect in the fuel system. The oily residue could affect
engine performance and create a cosmetic problem on and around the generator set.
Operation at rated load will burn off this oily residue. The length of time required at rated
load depends on the amount of residue. The muffler may also need to be removed and
cleaned if excessive build up occurs. This oily residue can be prevented by increasing
the electrical load on the set.
