ENGINE THROTTLE ADJUSTMENT TEST (continued)

Oscilloscope Method:

Vibratach Method:

1.Connect the oscilloscope to the 115 VAC receptacle, according to the manufactur- er’s instructions. At 3700 RPM, the wave- form should exhibit a period of 15.8 mil- liseconds. At 2200 RPM, the waveform should exhibit a period of 27.02 millisec- onds. Refer to NORMAL OPEN CIRCUIT VOLTAGE WAVEFORM (115 VAC SUPPLY) HIGH IDLE – NO LOAD in this section of the manual.

2.If either waveform periods is incorrect, adjust the throttle as follows:

Adjust HIGH IDLE: Use the 3/8” wrench to turn the spring-loaded adjustment nut. See Figure F.8 for location of the adjust- ment nut. Adjust the speed until the period is 15.8 mililseconds.

Adjust LOW IDLE: First make sure there is no load on the machine. Set the IDLER switch to AUTO and wait for the engine to change to low idle speed. Use the 3/8” wrench to adjust the solenoid nut, which changes the amount of throw in the throttle lever arm. See Figure F.9 for location of the adjustment nut. Adjust the speed until the period is 27.02 milliseconds.

1.Place the vibratach as close to the engine as possible. With the machine case top removed, the top of the air cleaner is the best location.

2.Start the engine and observe the whip handle of the vibratach. At HIGH IDLE (3700 RPM), the whip handle should exhibit maximum oscillation. At LOW IDLE (2200 RPM), the whip handle should exhibit minimum oscillation. Note that these are median measurements; vibrat- ach readings may vary slightly above or below.

3.If either of the vibratach indications is incorrect, adjust the throttle as follows:

Adjust HIGH IDLE: Use the 3/8” wrench to turn the spring-loaded adjustment nut. See Figure F.8 for location of the adjust- ment nut. Turn the nut clockwise to increase HIGH IDLE speed. Adjust the speed until the vibratach whip handle exhibits maximum oscillation at 3700 RPM.

Adjust LOW IDLE: First make sure that there is no load on the machine. Set the IDLER switch to AUTO and wait for the engine to change to low idle speed. Use the 3/8” wrench to adjust the solenoid nut, which changes the amount of throw in the throttle lever arm. See Figure F.9 for loca- tion of the adjustment nut. Adjust the speed until the vibratach whip handle exhibits minimum oscillation at 2150 to 2250 RPM.
