Disconnect the actuator linkage rod from the engine fuel shutoff lever.
Place the generator set START-RUN- STOP switch (located on the generator set control panel) in
the RUN position.
Place the generator set BATTLE SHORT SWITCH (located on the generator set control panel) in the
ON (override) position.
Beginning at the fully counterclockwise position, rotate the engine fuel shutoff lever in a clockwise
direction until a slight resistance is felt: hold the lever in this position.
NOTE
This resistance is the fuel injection pump’s internal governor linkage hook engaging the
metering valve arm.
Move the actuator lever to the “full fuel” position. This is the direction against the spring resistance
(fully counterclockwise).
Measure the center to center distance between the hole in the fuel shutoff lever and the hole in the
actuator lever. Adjust the rod ends on the threaded linkage rod so that the center to center distance
of the rod ends is the same or slightly longer than that measured between the fuel shutoff lever and
the actuator lever. (The 3.75 dimension is only approximate. If the linkage is too short, the actuator
lever will attain its “no fuel” position (full clockwise) before the fuel shutoff lever reaches its “no fuel”
position; the fuel shutoff lever will never reach “no fuel”. If the linkage is too long, the actuator lever
will reach its “full fuel” (full counterclockwise) before the fuel shutoff lever reaches its "fuII fuel”
position; full load will not be reached). It maybe necessary to readjust the position of the fuel shutoff
lever and/or the actuator lever to accommodate the center to center distance of the rod ends and to
assure complete fuel shutoff and full load operation. Fuel shutoff and actuator lever adjustments are
covered under replacement procedures. Tighten the nuts on the linkage rod against the rod ends to
maintain proper spacing.
Return the generator set START-RUN- STOP switch to the STOP position and the BATTLE SHORT
switch to the OFF position.
Reconnect the actuator linkage rod end to the engine fuel shutoff lever.
Adjust the control unit gain control to its approximate mid–range position.
Adjust the control unit stability control to its fully counterclockwise position.
Adjust the generator set frequency adjust potentiometer (pot) (located on the generator set control
panel) to mid-range.
Using a small screwdriver, slowly turn the control unit frequency adjust potentiometer (located on the
left side vertical face of the control unit) to the fully counterclockwise position (turn opposite increase
arrow). This may require up to 22 turns. The generator set will now be operating at the lowest
possible engine governed speed.
