LUBRICATION
Before starting the engine, check the oil level in the crankcase.
If it is low, rell to the full mark with the proper weight/grade of
oil as recommended by the engine manufacturer’s maintenance
instructions. The necessity of using the correct oil, and keeping
the crankcase full cannot be over emphasized. Failure to use
the proper oil and keep the crankcase properly lled will cause
excessive engine wear and shorten its useful life.

Use API CF or CH4
COOLANT
Before starting the engine, check the coolant level in the radiator.
If it is low, rell as specied in the engine manufacturer’s
maintenance instructions. The radiator should be lled to about
1 inch below the ller neck. For additional information on engine
coolant requirements see engine manufacturer’s maintenance
instructions.
INSTALLING THE BATTERY
**** CAUTION ****
In the following battery installation procedure, check to be
sure the engine control is in the “stop” position. This should
be your last step before initial start-up.
A customer supplied twelve-volt battery is required to complete
the installation. Installation of the highest CCA rated battery,
within the correct BCI group, will increase cold weather starting
performance.
