4-4. Engine Prestart Checks
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 10.
Fuel
Add fresh 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. Check fuel level on a
cold engine before use each day.
Do not run out of fuel or air enters fuel
system and causes starting problems.
See engine manual to bleed air from
fuel system.
Oil
After fueling, check oil with unit on level
surface. If oil is not up to full mark on
dipstick, add oil (see maintenance la-
bel). Unit stops if oil pressure is too low
or oil temperature is too high.
. This unit has a low oil pressure
shutdown switch. However, some
conditions 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 con-
crete surface.
Use fuel formulated for cold
weather (diesel fuel can gel in cold
weather). Contact local fuel sup-
plier for fuel information.
Use correct grade oil for cold
weather (see engine manual).
