Check the coolant level by observing the level in the
radiator and recovery bottle. Add 50/50 antifreeze /
water solution if the level is close to or below the
"LOW" mark. do not fill above the "FULL" mark.
Remove radiator cap and add coolant to radiator. Fill
up to the top of the tube in the radiator filler neck
which includes a connecting hose coming from the
thermostat housing.
To drain the coolant, open the valve at the bottom of
the radiator. Open the radiator cap to allow complete
drainage. (Tighten the valve and refill with a 50/50
antifreeze/water solution.) Use an automotive grade
(low silicate) ethylene glycol antifreeze. The cooling
system capacity is 7.9 qts. (7.5L). Squeeze upper and
lower radiator hoses while filling to bleed air from sys-
tem coolant. Replace and tighten the radiator cap.

- Low sulphur fuel or ultra low
sulphur fuel in U.S.A. and Canada only.
At the end of each day’s use, refill the fuel tank to min-
imize moisture condensation and dirt contamination in
the fuel line. Do not overfill; leave room for the fuel to
expand.
Use only fresh No. 2D diesel fuel, the use of No. 1D
diesel fuel is recommended in place of No. 2D at tem-
peratures below 23°F (-5°C). Do not use kerosene.
See the Engine Operator's Manual for instructions on
replacing the fuel filter.

You may need to bleed air from the fuel system if the
fuel filter or fuel lines have been detached, the fuel
tank has been ran empty or after periods of long stor-
age. It is recommended that the fuel shutoff valve be
closed during periods of non-use.
