Adding Engine Oil and Gasoline
Tip: To avoid confusion, we recommend leaving the caps on the gas and oil fills until you are ready to pour either gasoline or oil
into the correct fill.
Note: Use SAE 30 high detergent oil classified "For Service SF, SG, SH, SJ" or higher. Do not use special additives. Other types of oil
could cause problems operating your machine. Please refer to your Engine Owner's Manual for detailed oil information.

You must add oil before starting the engine. This machine is shipped without oil. Traces of oil may be in the reservoir from
factory testing, but you must add oil before starting the engine. Fill the reservoir slowly checking the dipstick frequently to
avoid overfilling.

To get an accurate reading when checking the oil level:
- The machine should be on a level surface.
- The dipstick should be pushed all the way down and turned a quarter turn clockwise (16.5) or screwed fully in (21.0 Model)
to ensure an accurate oil level reading.
