to
bring the unit up
to
its operating temperature before attempting
an
adjustment.
NOTE: If the governor
is
severely out
of
adjustment, manually adjust the linkage without any
load on the generator
to
obtain a safe output voltage before proceeding with the
adjustment
Three adjusting points are on the governor. (Refer to the illustraiion below.)

screw into the governor far enough so that it
in-
creases the no-load speed. To adjust the gover-

until the engine
stops
surging.

62.0 cycles no-load.
Applya
1/4, a 1/2 and a 3/4
load
to
the generator and ensure the generator
does not surge under these three
load intervals.
NOTE: Only If the generator surges at any
of these
load intervals are you
to
follow
steps
