MAINTENANCE

ENGINE

LUBRICATION

Maintenance, repair, or replacement of the emission control devices and systems, which are being done at the custom- ers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized engine manufacturer’s service outlet.

LUBRICATION

Use only high quality detergent oil rated with API service classifi cation SG–SL. Select the oil's SAE viscosity grade according to your expected operating temperature.

NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, and you should check your engine oil level frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine and after each fi ve (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.

4.Wipe off any spilled oil from lawn mower or side of engine.

5.Fill engine with oil. Slowly pour oil down the oil fi ll spout into the engine.

6.Wait one minute to allow oil to settle. Use guage on oil fi ll cap/dipstick for checking level. Insert dipstick into the tube and rest the oil fi ll cap on the tube. DO NOT thread the cap into the tube when taking reading.
