Mechanically connected toknobether cylinder by control cable. Pulling control releases ether;pushing it in shuts it off.8AmmeterIndicates battery charge or discharge in amperes (A). Electricallyconnected in series to battery circuit. Graduated in 30 A incre-ments from 0 to +60 A and 0 to -60 A.9Stop handleStops engine. Mechanically connected through the air shutoffcontrol wire to the mechanical governor. Pulling handle stopsengine operation through fuel starvation.10START pushbuttonStarts engine. Electrically connected to a relay which allowselectric current to flow to the starting solenoid. The startingsolenoid then allows current to flow to the starter motor.11ThrottleControls engine speed. Coupled to governor through a control wire.Uses a pushbutton lock. Pulling the throttle increases engine speed;pushing it in decreases engine speed.12TachometerIndicates engine speed in revolutions per minute (rpm) and elapsedtime in hours, tenths, and hundredths. Mechanically coupled torotating cable that is connected to the governor drive gear. Gradu-ated in 100 rpm increments from 0 to 3500 rpm. The elapsed timemeter will record up to 9999.99 hours of operation.13RestrictionIndicates blockage of air filter A red signal appears to indicate theindicatorneed for cleaning or replacement. Indicator is connected to airinlet housing by a flexible hose, and is actuated by high negativepressure. Indicator can be reset.Section II.
