Operating Section
5. Turn the ignition switch all the way out to the right,
when the engine starts release the ignition switch.
It should spring back to the first position.
IMPORTANT: If the ignition switch is released
before the engine starts, wait until the starter and
the engine stop turning before trying again. This
will prevent possible damage to the starter and/or
flywheel.
6. After the engine starts, continue to hold the Mur-
phy Switch in until the oil pressure gauge reads at
least 15 psi. The Murphy shut off switch will not
allow the engine to operate below this level. If the
gauge does not rise above 15 psi within 5 sec-
onds, stop the engine and determine the cause.
Normal operating oil pressure is 50 psi with oil at
normal operating temperature.
7. Check all gauges for normal engine operation.
If operation is not normal, stop the engine and
determine the cause.
IMPORTANT: To assure proper lubrication, oper-
ate the engine at or below 1200 rpm with no load
for 1 -2 minutes. Extend this period 2 - 4 minutes
when operating at temperatures below freezing.
8. Watch the coolant temperature gauge. Do
not place engine under load until it is properly
warmed up. The normal engine coolant tempera-
ture range is 180 - 202 degrees F.
