0000001501 TAMPER PROOF

Tamperproofing-equipped boost compensator cover installation procedure (A): After adjusting the boost compensator, assemble then tighten the bolts to remove the heads. (B): Specified torque (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)
