2.Before performing this test, clear the area around the trowel. Make sure it is free of debris and objects. Move the safety stop switch lever to the "ON" position, restart the engine and let idle.

Stand behind the handle and spin the handle to the right, simulating a runaway situation. (See Figure 27). Centrifugal force should throw the safety switch outward to the "OFF" position thus shutting off the engine.
