SW:Inner hexagonal SW14
(F): Apply thread lock adhesive .
(G): Full tamper proof
(H): Full boost (Full rack)
(I): 0 boost
1. Mount (C) and (D) after adjusting the boost compensator.
2. Back off the load lever set screw L1 from the end face of the governor housing..
3. Apply boost pressure and set the full load at tamper set position point aa to obtain N1, Q1 and Ra using the screw C.
4. Fix using the nut (D).
5. Next, after adjusting the stop lever, confirm the point aa.
6. Reset the load lever to the full boost rack.
7. After completion of setting, seal using the plug (E).
