Note: Before you check the engine oil, do not operate the engine for at least 10 minutes in order to allow the engine oil to return to the oil pan.
Check the crankcase oil level. Maintain the oil level between the "MIN" mark and the "MAX" mark on the oil level gauge.
If necessary, perform minor adjustments. Repair any leaks and tighten any loose bolts.
Note the service hour meter reading. Perform the maintenance that is in the Operation and Maintenance Manual, "Maintenance Interval Schedule".
Fill the fuel tank in order to help prevent accumulation of moisture in the fuel. Do not overfill the fuel tank.
Only use antifreeze/coolant mixtures recommended in the Coolant Specifications that are in the Operation and Maintenance Manual. Failure to do so can cause engine damage.
Allow the engine to cool. Check the coolant level. Maintain the cooling system at 13 mm (0.5 inch) from the bottom of the pipe for filling.
If freezing temperatures are expected, check the coolant for proper antifreeze protection. The cooling system must be protected against freezing to the lowest expected outside temperature. Add the proper coolant/water mixture, if necessary.
Perform all required periodic maintenance on all driven equipment. This maintenance is outlined in the instructions from the OEM.
