engine for several minutes. Check for fuel leaks, and
noises that would associate with a loose guard ring
and/or covers.
Testing the centrifugal Safety Stop Switch
1. With the engine running at idle, place the safety stop
switch lever in the "Off" position (Figure 26). Verify
that the engine shuts off. If the engine continues to run,
replace centrifugal safety stop switch.

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.
