Recommendations and Tips

The basics of proper operation

Following these rules is desirable for all owners of various equipment, which is equipped with four-stroke engines manufactured by Briggs&Stratton.

Oil selection

Corporation experts recommend using only genuine Briggs oil.&Stratton, the following brands: SG, SF, SH, SJ. At the same time, SG brand oil can be used in summer, and 10W30 in winter. This can significantly reduce engine wear. It is worth noting that 10W30 and 5W30 oils can be used in any season.

Fuel selection

It is best to use pure gasoline that does not contain any additives (such as oil). The octane number in this case should be at least 77. This indicator corresponds to A-80, AI-98, AI-92, AI-95. To increase fuel efficiency it is necessary to use special additives. Another important point is the need for an incomplete filling of the gas tank. This avoids fuel loss during expansion. It is important to remember that the use of a mixture of alcohol-gasoline and ether-gasoline significantly reduces not only the efficiency of engine use, but also the duration of its service.

Air filters care and maintenance

There are several varieties of air filters, among which the main ones are dry and wettable with oil. Care for a wettable filter is as follows: it must be washed regularly, squeezed and moistened with engine oil using a soft material. The dry air filter is cleaned using normal mechanical action (tapping). If it has severe pollution, then it must be replaced. Briggs Engine Safety&Stratton. First, do not forget that in enclosed spaces it is strictly forbidden to use such engines. Since the emission of exhaust gases can damage human health. Secondly, do not refuel a hot engine. Thirdly, during maintenance, it is necessary to remove contact from the spark plug. In addition, it must be remembered that the operation of an engine without a silencer is also dangerous.
