OPERATING INSTRUCTIONS
Abnormal Conditions
Under abnormally overheated conditions, the engine may continue to run after the ignition
switch is turned off. If this case is ever encountered, turn on the ignition switch
immediately and allow the engine to idle until it has cooled enough to stop. If the engine is
overheated due to a loss of coolant, it is best to stop the engine immediately, if necessary
by applying the load. Allow the engine to cool, then check the coolant and oil levels. Add
engine oil if necessary, then, after the engine has returned to a normal temperature, add
coolant slowly until the radiator is full.
CAUTION - Avoid injury when checking a hot engine. Cover the radiator cap in a
thick cloth and turn it slowly counter-clockwise to the first stop. After the pressure has
been completely released, press the cap downward and finish removing the cap.
The above instructions also apply to engines that stop due to operation of the low
oil pressure-high water temperature safety switch. However, if engine stops due to low oil
pressure, do not restart until the cause has been determined and corrected.
SPECIAL SITUATIONS
Problem Diagnosis
Most operating troubles that might be encountered with a new or well maintained
unit will be of a minor nature. Therefore, if you have troubles starting or operating your
engine, look for some simple cause rather than failure of a major component. For
instance: Loose or corroded battery connections arc much more likely than battery failure.
A loose ignition wire is much more likely than distributor, coil or ignition system
failure.
In many cases, engine operating troubles are coupled with outside factors, such
as climatic conditions, operating conditions, change of servicing or fueling source, or
change of operator.
Engine troubles that occur as a result of normal use and wear usually give plenty
of advance warning. These troubles usually result from overlooking the Scheduled
Preventive Maintenance Services (Page 14).
