OPERATION
CHECK THE OIL (BEFORE STARTING ENGINE)
NOTE: The engine was shipped from the factory filled with oil. Check the level of the oil. Add oil as needed.
1. Make sure the unit is level. Use a high quality detergent oil classified “For Service SG, SH, SJ, SL, or higher”.
2. Remove the oil fill cap/dipstick (A, Figure 6) and wipe with a clean cloth.
3. Insert the oil fill cap/dipstick and turn clockwise to tighten.
4. Remove the oil fill cap/dipstick and check the oil.
NOTE: Do not check the level of the oil while the engine runs.5. If necessary, add oil until the oil reaches the FULL mark on the oil fill cap/dipstick. Do not add too much oil.

| High Altitude |
|
|
|
|
|
|
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane/85 AKI (89 RON) gasoline is acceptable. To remain emissions compliant, high altitude adjustment is required. Operation without this adjustment will cause decreased performance, increased fuel consumption, and increased emissions. See a Briggs & Stratton Authorized Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762 meters) with the high altitude kit is not recommended.
1.Clean the fuel cap area of dirt and debris. Remove the fuel cap (H, Engine Controls).
2.Fill the fuel tank with fuel. To allow for expansion of the fuel, do not fill above the bottom of the fuel tank neck.
3.Reinstall the fuel cap.
