NOTICE

This engine was shipped from Briggs & Stratton without oil. Equipment manufacturers

or dealers may have added oil to the engine. Before you start the engine for the first

time, make sure to check the oil level and add oil according to the instructions in this

manual. If you start the engine without oil, it will be damaged beyond repair and will not

be covered under warranty.

We recommend the use of Briggs & Stratton Warranty Certified oils for best performance.

Other high-quality detergent oils are acceptable if classified for service SF, SG, SH, SJ or

higher. Do not use special additives.

Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to

select the best viscosity for the outdoor temperature range expected. Engines on most

outdoor power equipment operate well with 5W-30 Synthetic oil. For equipment operated

in hot temperatures, Vanguard™ 15W-50 Synthetic oil provides the best protection.

SAE 30 - Below 40 °F (4 °C) the use of SAE 30 will result in hard starting.A

10W-30 - Above 80 °F (27 °C) the use of 10W-30 may cause increased oil

consumption. Check oil level more frequently.
