4-7. Engine Prestart Checks
. Check all engine fluids daily.
Engine must be cold and on a level surface.
Unit is shipped with 20W break-in oil.
Automatic shutdown system stops engine if
oil pressure is too low, or coolant tempera-
ture is too high.
. 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.
Follow run-in procedure in engine manual.
Fuel
Add fresh fuel before starting engine the first
time (see engine maintenance label for fuel
specifications).
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).
Coolant

ing unit the first time. If necessary, add cool-
ant to radiator until coolant level is at bottom
of filler neck.
Check coolant level in recovery tank daily.
If necessary, add coolant to recovery tank
until coolant level is between Cold Full and
Hot Full levels. If recovery tank coolant level
was low, also check coolant level in radiator.
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 the unit in tempera-
tures below –34° F (–37° C).
Keep radiator and air intake clean and free
of dirt.
Y Incorrect engine temperature can
damage engine. Do not run engine
without a properly working thermo-
stat and radiator cap.
. To improve cold weather starting:
Keep battery in good condition. Store
