may be pulled to stop the engine. The emergency stop knob, when pulled, will trip the air shut-off valve located between
the air inlet housing and the blower and shut off the air supply to the engine. Lack of air will prevent further combustion
of the fuel and stop the engine.
The emergency stop knob must be pushed back in after the engine stops so the air shut-off valve can be opened for
restarting after the malfunction has been corrected.
The engine throttle is connected to the governor speed control shaft through linkage. Movement of the speed control
shaft changes the speed setting of the governor and thus the engine speed.
