Inspection & Adjustment
4 ) By the operation of the F-R lever, load the
engine so that its revolution is reduced
from high idle (2,580 min
-1
) (2,580 rpm) to
the rated speed (2,300 min -1 ) (2,300 rpm).
Read the pressure at the rated revolution
and return the F-R lever to the neutral
position as quickly as practicable.
★ The procedure (Tilting the F-R lever
➡
Reading the pressure
➡
Bringing
the F-R lever to neutral) should not
exceed 3 seconds.
5 ) When the measurement is complete, reset
the cut off valve by screwing out cut off
valve adjust screw (5) one full turn and
tightening locknut (4).
6) Ensure that the cut off valve setting is

• Tightening torque:
Item (3): 22 N ・ m (224 kgf ・ cm) {16.2 lbf ・ ft}
Item (4): 35 N ・ m (357 kgf ・ cm) {25.8 lbf ・ ft}
★ Carefully perform disassembly and
reassembly taking necessary mea-
sures to prevent ingress of foreign
matter.
2) To adjust the setting, loosen locknut (4)
and rotate adjust screw (5).
• Adjust screw rotation:
Clockwise
➡
Pressure increases
Counterclockwise
