dyed red for identification. It may take several fill-
ings of the fuel tank before the red dye is purged
from the fuel system.

IMPORTANT:
Use only low sulfur or ultra-low sul-
fur diesel fuel to maintain proper engine perfor-
mance. BioDiesel mixtures of up to a 5% (B5) are
acceptable. Ultra-Low Sulfur Diesel (ULSD) fuel
lubricity must have a maximum scar diameter of
0.45 mm, as measured by ASTM D6079 or ISO
12156-1, or a minimum of 3100 grams, as mea-
sured by ASTM D6078. Contact your fuel supplier
for details. Also see See "Fluids/Lubricants Types
and Capacities" on page 31 and the engine opera-
tion manual.
5. When the fuel tank is full, replace and lock fuel
cap (F) in the fuel filler neck opening.
IMPORTANT:
To provide for proper fuel system
venting, do not top off the fuel tank.

Water Separator Inspection/Maintenance

NEVER service the fuel system while smoking,
while near an open flame, or after the engine
has been operated and is hot.
IMPORTANT:
Water in the fuel system can cause
severe engine damage. Drain water from the fuel fil-
ter/water seperator anytime water is present.
Inspect the water separator weekly, or after every 50
hours of use.
The water separator contains an indicator ring (M,
Fig. 96) that floats on top of accumulated water.
Under normal conditions, the ring sits at the bottom
of the separator cup. If the ring is somewhere
between the top and bottom the cup, water must be
drained.
1. Perform the "Mandatory Safety Shutdown Pro-
cedure" on page 16.
2. Wait until the engine has cooled. See
"Maintenance and Service Safety Practices" on
page 21.
3. Open the engine cover "Engine Access" on
page 103.
