Maintenance Procedures
Engaging the starter motor for more
than 30 seconds in any 5 minute pe-
riod may cause it to overheat and
can damage the starter motor.
•
If starter is engaged continuously
for 30 seconds, you must wait 5
minutes before trying to start the
engine to allow the starter motor
to cool down.
CAUTION
4. If the engine does not start within
this time, allow the starter motor
to cool down for at least 5 minutes
before repeating the procedure.
Do not loosen any fuel line fittings in
order to bleed the fuel system of air.
The system is under high pressure
which, when relieved, could cause
death, personal injury, equipment or
property damage.
WARNING!
Replacing Coolant Filter
Your engine may be equipped
with a Coolant Filter designed to
capture and remove harmful deposits
from the cooling system to help
prolong system life. Refer to the
“Maintenance Schedule” beginning for
the recommended coolant filter change
service interval.
WARNING!
Do not remove the radiator cap on
a hot engine. It can cause scalding
coolant to spray out and you could
be burned. If the engine has been
operated within the last 30 minutes,
be very careful in removing the radi-
ator cap. Failure to comply may re-
sult in death, personal injury, equip-
ment or property damage.
•
Protect face, hands, and arms
against escaping fluid and steam
by covering the cap with a large,
thick rag.
WARNING!
Handle coolant and antifreeze care-
fully. Ethylene glycol antifreeze is
poisonous. Store in original fluid
container only, and always keep out
of the reach of children. Failure to
comply may result in death, personal
injury, equipment or property dam-
age.
•
Also, never remove the cap on
the surge tank while the engine
is still hot. Wait until the coolant
temperature is below 120°F
(50°C). Scalding steam and fluid
under pressure may escape and
cause serious personal injuries.
