Operation & Maintenance Manual and User Service Guide Notice 1. Before the first use, the engine should go through a 50h trial run. For more information, refer to the running-in requirements. 2.

It is necessary to idle for 5-10 min at low speed. 3. It is prohibited to work without air filters which could prevent air from entering the cylinder without being filtrated.
The air filter should be regularly maintained or replaced, otherwise power reduction, parts wearing and other problems would happen. 4.
