When changing the engine oil, replace the oil lter. Drain the
used oil from the engine crankcase immediately after a journey while
it is still hot. In this case, the oil pours out quickly and completely.
Remove the oil lter 10 (see Fig. 9.3) by turning it counter-
clockwise. When installing a new lter, make sure that the rubber
O-ring is in proper condition and lubricate it with engine oil, turn
the lter until the O-ring touches the plane on the engine block and
then tighten the lter with a 3/4 turn. Make sure no oil leak exists.
With the engine warm and the lubrication system intact, the
emergency oil pressure warning lamp may be on at idle, but it
shall go out immediately after increasing the crankshaft rpm.
It is recommended to ush the engine lubrication system after
each two oil changes. For that purpose, drain the used oil, ll in
special ushing oil (VNIINP-FD) 3-5 mm over the “MIN” mark
on the oil level indicator and let the engine run for 10 minutes.
