6.4.1.2 Operation 1. Check of oil level in the engine crankcase
Check oil level after putting the tractor on a flat surface and not earlier than 3-5 min
after the engine is switched off, when the oil completely flows down to the crankcase.:
To check oil level in the engine crankcase, do the following:
- take dipstick 3 out (Figure 6.4.1), wipe it clean and then put it back against the
stop;
- take dipstick 3 out and define the oil level. The oil level shall stay between the up-
per and lower marks of the dipstick. If required, top up the oil through neck 1 after remov-

ATTENTION: DO NOT RUN THE ENGINE WITH THE OIL LEVEL BELOW THE
LOWER MARK ON THE DIPSTICK!

tity in the expansion tank shall stay at the level ranging from 20...30 mm from the expan-
sion tank bottom to the upper edge of clamp 2 fastening the expansion tank. If the coolant
level is lower than 20...30 mm from the expansion tank bottom, then open plug 4 of ex-
