Tamperproofing-equipped boost compensator cover installation procedure
(A) After adjusting the boost compensator, tighten the bolts to remove the heads.
(1)Before adjusting the governor and the boost compensator, tighten the screw to the specified torque.
(Tightening torque T = T1 maximum)
(2)After adjusting the governor and the boost compensator, tighten to the specified torque to break off the bolt heads.
(Tightening torque T = T2)
----------
T1=2.5N-m(0.25kgf-m) T2=2.9~4.4N-m(0.3~0.45kgf-m)

Information:
Accidental engine starting can cause injury or death to personnel working on the equipment.To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system.Place a Do Not Operate tag at the Start/Stop switch location to inform personnel that the equipment is being worked on.
2301A Electric Governor Control
The 2301A Electric Governor Control activates all of the components that are in the electric protection system. The components are activated in the same manner when the nonelectric governor is used. One difference exists in the main circuit. The fuel shutoff solenoid (FSOS) (line 43) is not used.When the electric governor control is used, the engine must run in a normal condition in order for the electric circuit to operate in the manner that is described below.
Current flows from the terminals (TS-28) (line 43) and (TS-31) (line 44), which are located on the terminal strip in the junction box.
Current from terminals (TS-28) (line 43) and (TS-31) (line 44) flows through the preregulator (PR) (line 48) or the fuse (F4) to the electric governor control.
When the engine flywheel is rotating, the current also flows through the electric governor actuator (EGA) (line 52). When a fault in the system causes the current to energize the slave relay (SR1), the following events occur in the electric circuit in order to stop the engine.
The slave relay (SR1) opens across the contacts (SR1-30) and (SR1-87a) (line 45). The relay closes across the contacts (SR1-30) and (SR1-87) (line 43).
When the circuit opens across contacts (SR1-30) and (SR1-87a), the current is stopped to the electric governor control.
Current to the electric governor actuator (EGA) is also stopped.
The mechanical spring load in the electric governor actuator (EGA) will now move the fuel control rod in order to stop fuel flow to the engine. Note: With the exception of the differences that are described in this section of the manual, all of the fault circuits in the electric protection system are identical for the 2301A Electric Governor Control and for the nonelectric governor control.
