FIGURE 25. GOVERNOR ADJUSTMENTS (BEGINNING WITH SPEC R)
Sensitivity: Models starting with Spec R (Figure 25).
Adjust by turning the sensitivity adjusting ratchet nut;
accessible through a hole inside of blower housing. If
speed drops too much when full load is applied, turn
the ratchet nut counterclockwise to increase spring
tension and compensate for reduced rpm. An over-
sensitive adjustment, approaching no speed drop when
load is applied, may result in a hunting condition
(alternate increase and decrease in speed).
After adjusting speed and sensitivity, secure speed-
stud lock nut and replace dot button in blower housing.
