1.Connect the oscilloscope to the 115 VAC receptacle, according to the manufacturer’s instructions. At 3700 RPM, the waveform

should exhibit a period of 16.2 milliseconds. At 2200 RPM, the waveform should exhibitNORa- MALperiod OPENof 27.3CIRCUITmillisecondsVOLTAGE. Refer toWAVE-

FORM (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” wrenchFigureto t n the spring-loaded adjustment nut. See

F.8

for location of the adjustment nut. Adjust the speed until the period is 16.2 milliseconds.

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 amountFigure F.of9 throw in the throttle lever arm. See

for location of the adjustment nut. Adjust the speed until the period is 27.3 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 oscilla- tion. Note that these are median measure- ments; vibratach readings may vary slightly above or below:

3.If either of the vibratach indications is incor- rect, adjust the throttle as follows:

Adjust HIGH IDLE: Use the 3/8” wrenchFigureto t n the spring-loaded adjustment nut. See

F.8

for location of the adjustment nut. Turn the nut clockwise to increase HIGH IDLE speed. Adjust the speed until the vibratach whip han- dle exhibits maximum oscillation at 3650 to 3750 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 theFigureamountF.of9 throw in the throttle lever arm. See

for location of the adjustment nut. Adjust the speed until the vibratach whip handle exhibits minimum oscillation at 2150 to 2250 RPM.
