General maintenance
Operation 48. Adjusting drain valve
of centrifugal oil filter of engine
If during the engine operation within the
rated mode at normal temperature (80 to
100°C), the oil pressure has dropped be-
low 0.1 MPa, stop the engine and cor-
rect the fault.
One of the ways to increase pressure is
readjustment of the centrifuge drain
valve. To do this, remove the thread plug
(not shown) and readjust oil pressure by
screwing the adjustment screw (1) with a
screw-driver into the body. If this method
does not eliminate the defect, contact
the dealer.
