2. To decrease speed, loosen locking nut on speed adjusting
screw, and turn screw in counterclockwise direction.
3. When the speed is correct, tighten the locking nut at the
new setting.
7-9.3. Sensitivity Adjustment. If the governor is too sensi-
tive, speed surging will occur with change in load. If the
governor is not sensitive enough, a big drop in speed will oc-
cur when normal load is applied.
I. To make the governor more sensitive, loosen the nut at
bottom of adjusting eyebolt and tighten the top nut there-
by drawing the head of the eyebolt closer to the governor
arm pivot point.
2. To make the governor less sensitive, loosen the top nut
and tighten the bottom nut to move the head of the eye-
bolt away from the pivot point.
3. After sensitivity is correct, tighten the nut that was pre-
viously loosened to lock the eyebolt at the new setting. Re-
check speed after sensitivity adjustment since changing this
will also affect speed.
