Governor
Adjustments
Operate the generator set
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 illustration below.)
1.
Bumper Screw This screw is used
to
remove
a
no-load
surge
ONLY.
NEVER
turn the bumper screw into the
governor far enough so that it increases
the
no-load speed. To adjust the gover-
nor, turn the bumper screw in until the
engine stops surging. Now bring the
Increase/Decrease
Speed Screw (on
the governor) up until the generator
runs between 60.5
to
61.5 cycles no-
load. Apply a 1/4, a 1/2 and a 3/4 load
to
the generator and ensure the gener-
ator 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
#2
and
#3
below.
2.
Increase/Decrease Speed This adjust-
ing
bolt sets the no load speed of the
engine. (The
linkage arm between the
governor arm and throttle lever should
be adjusted
to
hold the throttle full open
when the engine
is
not running.) Make
sure this
linkage moves freely and that
the
ball joint connectors are properly
lubricated. Use graphite lubricant at
this connection. Disconnect the
ball
joint and apply a graphite lubricant
to
the inside of the joint.

!f
the
variation
in
engine speed between no load and full
load
is
too
great, adjust this eye bolt
to
draw the spring closer
to
the lever hub.
The increase/decrease speed
boll may
need
to
be
adjusted as well.
