L1:Inspection dimension
Fig. 1 Regulating valve seal
1) Target breaking torque T1
2) Maximum allowable breaking torque T2
3) Because the cap and the regulating valve are fixed using the MEC process, the bolt cannot be loosened after the bolt has been broken.
Fig.2 Full load adjusting screw
1) Confirm the position of the rubber vibration damper (B) and then tighten nut (C) to the torque T3.
Fig. 3 Maximum speed adjusting screw
1) Tighten nut (E) to the torque T4.
2) To prevent nut (E) from turning together, fix (E) using the tool, then tighten nut (F) to torque T4.
