  Do not make any unnecessary adjustments. 
Factory settings are correct for most applica-
tions. However, when making adjustments, be 
careful to avoid overspeeding the engine.
If this procedure or equipment are not available, 
locate the nearest Authorized Dealer and they can 
perform the adjustments.
NOTE:
A service fee may be charged for this adjustment.
2.7  ENGINE GOVERNOR ADJUSTMENT
If both AC frequency and voltage are correspondingly 
high or low, adjust the engine governor as follows:
2.7.1  7 KW UNITS
1.  Loosen the governor clamp bolt (Figures 2.3 and 
2.4).
2.  Hold the governor lever at its wide open throttle 
position, and rotate the governor shaft clockwise 
as far as it will go. Then, tighten the governor 
lever clamp bolt to 70 inch-pounds (8 N-m).
3.  Start the generator; let it stabilize and warm up 
at no-load.
4.  Connect a frequency meter across the generators 
AC output leads.

5.  Turn the primary adjust screw to obtain a fre-
quency reading of 61.5 Hz. Turn the secondary 
adjust screw to obtain a frequency reading of 
62.5 Hz.
6.  When frequency is correct at no load, check the 
AC voltage reading. If voltage is incorrect, the volt-
age regulator may require adjustment.
