resistance becomes the hardest at a certain position, corre-
sponding to the compression point. Pull the starter grip briskly
and smoothly for starting.

6. If the engine has started, slowly return the choke lever
(Figure 24) to the
OPEN
position. If the engine has not started
repeat steps 1 through 5.
7. Before the trowel is placed into operation, run the engine for
several minutes. Check for fuel leaks, and noises that would
associate with a loose guard ring and/or covers.
8. Test the Safety Stop Switch.
a. With the engine at idle, move the safety stop switch lever
to "OFF" (Figure 23). The engine should shut off.
b. CLEAR THE AREA AROUND THE TROWEL. Move
the safety stop switch lever back 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 26). Centrifugal force should
throw the safety switch outward to the "OFF" position
thus shutting off the engine
