(d) Adjust using the tension lever bolt to obtain L.
(2)Setting full load rack position Rf
(a) Move the load control lever to the full side.
(b) Adjust the full load adjusting bolt so that Rf can be obtained, then fix.
(3)Setting the beginning of high speed operation Nf
(a) Adjust using bolt (E) so that Nf can be obtained, and then fix.
(4)Idle control setting (Re, Ni, Rc)
(a) Set the speed at Ns + 200r/min and move the load control lever to the idle side.
(b) Fix the lever in the position where Re can be obtained.
(c) Next, decrease speed to Ni and screw in the idle spring.
(d) Adjust to obtain rack position Ri.
(e) Increase the speed and after confirming that the rack position is Re at Ns, set the speed at 0.
(f) Confirm protrusion position Rc at idle.
(5)Damper spring adjustment
(a) Increase speed and set the speed at the rack position Rd - 0.1 mm
(b) Set using the damper spring so that the rack position Rd can be obtained.
(c) When Rd is not specified, Rd = Ri - 0.5 mm.
(6)High speed droop confirmation
(a) Return the load control lever to the full load lever position.
(b) Increase the speed and confirm that Rf can be obtained at Nf r/min.
(c) Confirm that speed is Nh at rack position Rh.
2. Variable speed specification adjustment (at operation)
(a) Remove return spring (D).
(b) Apply air pressure of 245~294 kPa {2.5~3 kg/cm2} to the air cylinder.
(c) Perform the following adjustment in this condition.
(1)Setting full load rack position Rf'
(a) Pull the load lever to the idle side.
(b) Obtain rack position Rf' using the nut (C). (Pump speed is Nf'-50 r/min.)
(2)Setting full speed Nf'
(a) Adjust using bolt (B) so that Nf can be obtained, and then fix.
(3)Low speed side setting
(a) At 350r/min, set bolt (F) at beginning of governor operation position, then fix.
3. Bolt (A) adjustment
(1)Install return spring (D) and perform the adjustments below at air pressure 0.
(a) Set at speed Nf using bolt (E).
(b) Screw in bolt (A).
(c) Screw in 1 more turn from the speed lever contact position
(d) Fix bolt (A).
(e) At this time confirm that the air cylinder's shaft moves approximately 1 mm towards the governor.
4. Lever operation confirmation using the air cylinder
(1)Apply 588 kPa {6 kg/cm2} air pressure to the air cylinder.
(2)Confirm that the cylinder piston is moved 50 mm by the spring (D).

Circuit breaker
(1) Reset button
(2) Disc in open position
(3) Contacts
(4) Disc in closed position
(5) Battery circuit terminals A circuit breaker is a switch that opens the circuit if the current in the electrical system is higher than the rating of the circuit breaker.A metal disc that is controlled with heat and a contact (3) will complete the circuit through the circuit breaker. If the current in the electrical system is too high, the metal disc becomes too hot. The heat causes a distortion of the metal disc which opens the contacts (2). Open contacts break the circuit. A circuit breaker that is open can be reset after the circuit breaker cools. Push the reset button (1) in order to close the contacts (4) and reset the circuit breaker.
Find and correct the problem that causes the circuit breaker to open.Correcting the problem before running the engine will help prevent damage to the circuit components caused by too much current.

(5) Air shutoff solenoid that is mounted in the air intake pipe.
The air shutoff solenoid (5) is located in the air inlet system on the top of the engine. When the air shutoff solenoid ("ASOS") is energized, the inlet air to the engine is mechanically shut off. The ASOS can be energized in the following two ways:
The ASOS is energized by the overspeed switch (OS).
The ASOS is energized by the emergency stop switch (ES).Fuel Solenoid (FS)

(5) Shaft
Illustration 12 g00293070
(4) Fuel solenoid (FS) that is mounted on the governor.
The fuel solenoid (FS) (4) is located on the governor or on the fuel injection pump of the engine. When the FS is energized, the spring (2) and the shaft (5) will cause the fuel rack to move directly or the fuel rack will move through the governor drive to the FUEL ON position. The FS must remain energized or the fuel flow will be stopped to the engine. 2301A Electric Governor Control
Illustration 13 g00293071
(1) 2301A Electric Governor Speed Control
Illustration 14 g00293069
Electric governor actuator (EGA) (2) and fuel solenoid (FS) (3). The components are mounted on the top of the engine.
The 2301A Electric Governor Control system consists of the following components:
2301A Control
Actuator (EGA)
Magnetic pickup (MPU)The 2301A Electric Governor Control system provides precision engine speed control. The 2301A Control constantly monitors the engine rpm. The control makes the necessary corrections to the engine fuel setting through an actuator that is connected to the fuel system.The engine rpm is measured by the magnetic pickup ("MU"). The magnetic pickup makes an AC voltage that is sent to the 2301A Control. The 2301A Control then sends a DC voltage signal to the actuator in order to adjust the fuel flow.The actuator changes the electrical signal from the 2301A Control to a mechanical output. The mechanical output of the actuator causes the linkage from the actuator
