0000001501 TAMPER PROOF

(A): sealing wire (B): full load stopper bolt (C): load lever (D): governor cover boss (E): tamper lever installation bolt ST:Sealing a, b: load lever angle 1. Method for setting tamperproof proofing (1)After completing governor adjustment, install lever marked A when the load lever (C)'s angle is equal to or greater than a but less than b, and lever marked B when angle is equal to or greater than c but equal to or less than d (as shown in figure). Sealing A: PN1 Sealing B: PN2 (2)At R1 and N1 loosen bolt B until the lever installed in (1) contacts the governor cover boss. (3)Confirm that the rack position at this time is R = R2 or less. (4)After this, readjust the full rack position using the load lever C. (5)Seal bolt E.
