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 col-
lect in exhaust pipe during run-in, see
Section 9.
Fuel
Y Do not use gasoline. Gasoline
will damage engine.
Add fresh diesel fuel before starting
engine the first time (see mainte-
nance 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
system and causes starting prob-
lems. See engine manual to bleed air
from fuel system.
Oil
After fueling, check oil with unit on lev-
el surface. If oil is not up to full mark on
dipstick, add oil (see maintenance la-
bel).
.
Your unit may have the optional
low oil pressure shutdown
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.
.
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.
