STEP 1. Move the governor control knob to the GOVERN or RUN position.
STEP 2. Start engine and allow engine to warmup at rated speed for 3 to 5 minutes.
STEP 3. Apply load. Loosen locknut A and turn minimum speed stop screw to obtain engine speed/frequen-
cy given in lines A of above table. Tighten locknut A.
STEP 4. Disengage load and check engine speed/frequency. If speed/frequency does not exceed values given
in table above, lines B, no further adjustment is necessary. If speed exceeds values of table above,
lines B, perform steps 5 and 6.
STEP 5. Loosen locknut B and turn governor spring adjustment nut clockwise 4 turns. Tighten locknut B.
STEP 6. Perform steps 3 and 4. NOTE: If no-load speed is adjusted too close to load speed, instability or hunt-
ing will occur. If instability occurs, adjust governor spring adjustment nut to obtain no-load speed/fre-
quency indicated in Table 1, Column B. Then perform steps 3 and 4 to obtain stability.
