IF cleaning the screens and indicator does not re-
store the water pump indicator’s steady discharge,
SHUT OFF the engine and do not attempt to oper-
ate it. See your DEALER.
IF cleaning the screens and indicator does restore
the water pump indicator’s steady discharge, you
might have to run for two minutes in NEUTRAL to
allow the engine to cool and the light to go off.
Low Oil Pressure Warning
Should the oil pressure drop to a dangerously low
level, the System Check engine monitor will sound
the horn and turn on the “NO OIL” light. Also, the
EMM will immediately limit the engine speed to
3000 RPM. This additional protective feature is re-
ferred to as S.L.O.W. If the engine was running fast-
er than 3000 RPM when the S.L.O.W. system
activated, it will shake noticeable.
If the warning light stays on after two minutes,
STOP the engine and see your DEALER.
In case of low oil pressure:
IMPORTANT: You must restore cooling to the en-
gine to avoid serious engine damage.
Shut OFF engine.
If tilted, place the engine in vertical position.
After any overheat, have your DEALER:
Torque the cylinder head screws.
Inspect the water pump for excessive wear or dam-
age.
Inspect the thermostats.
Inspect the engine for leaks.
Inspect water pressure valve.
Check engine oil level.
Check the oil level on the dipstick and add oil, if
needed. Refer to Crankcase Oil and Filter and
Engine Specifications.
Examine the oil fill cap, filter, and drain screw for ev-
idence of leakage. Make sure each is tight.
If dipstick shows that the oil level is okay, leave the
engine upright and shut off for 10 minutes, then
start it. If the engine still limits itself to about 3000
RPM, see your DEALER.
IMPORTANT: DO NOT attempt to run your engine
if it repeatedly loses oil pressure. See your DEAL-
ER.
