Check all fluids daily. Engine must be cold
and on a level surface.
Follow run-in procedure in engine manual. If
unburned fuel and oil collect in exhaust pipe
during run-in, see Section 9.
1 Fuel
Y Do not use gasoline. Gasoline will
damage engine.
Add fresh diesel fuel before starting engine
the first time (see maintenance label for
specifications). Fill fuel tank up to 1/2 in. (13
mm) from top to allow room for expansion.
Open fuel shut-off valve.
Do not run out of fuel or air enters fuel sys-
tem and causes starting problems. See en-
gine manual to bleed air from fuel system.
2 Oil
After fueling, check oil with unit on level sur-
face. If oil is not up to full mark on dipstick,
add oil (see maintenance label).
Y Engine may use oil and wetstacking
may occur during run-in period.
Check oil several times daily during
run-in.
.
This unit has a low oil pressure shut-
down switch. However, some condi-
tions may cause engine damage before
the engine shuts down. Check oil level
often and do not use the oil pressure
shutdown system to monitor oil level.
3 Coolant
Add coolant if level is below bottom of radia-
tor filler neck. Engine coolant is a mixture of
water and ethylene glycol base antifreeze.
Add anti-freeze to mixture if using unit in
temperatures below 0
°
F (–18
°
C).
Keep radiator, air intake, and cooling fins
clean and free of dirt.
Y Incorrect engine temperature can
damage engine. Do not run engine
without a properly working 180
° F
(80
°
C) thermostat and a 7 psi (48 kPa)
radiator cap.
.
To improve cold weather starting:
Keep battery in good condition. Store
battery in warm area off concrete
surface.
Use fuel formulated for cold weather
(diesel fuel can gel in cold weather).
Contact local fuel supplier for fuel
information.
Use correct grade oil for cold weather.
