above freezing 32°F (0°C).
b. Use grade no. 1 at ambient temperatures below
freezing and for all temperatures at an altitude
of above 5,500 ft. (1500 meters).
2. Use fuel having less that 1% sulphur (preferably
less that 0.5%).

Figure 9: Primary Fuel Filter.
1. Your generator set should have a primary fuel filter
installed. We recommend the Racor brand of fuel
filter-water separators.
a. Check the primary fuel filter daily as
recommended by the filter manufacturer.
Empty the collection bowl as necessary.
b. Change the element as often as necessary or
every 500 hours.
c. If the bowl fills with water, change the primary
and secondary element immediately.
2. Change secondary fuel filter every 500 hours.
NOTE: The fuel filter on the engine is considered the
“secondary fuel filter.”
a. Remove the spin-on filter by turning it
counterclockwise with a filter wrench. Fill the
new cartridge with fuel and install it after
applying engine oil to gasket surface. Screw on
until the gasket surface comes into contact with
sealing surface of filter base. Then, tighten it
two-thirds of a turn by hand. Do not overtighten.
