Action 3. Checking the oil level in the
hydraulic system tank
NOTE: Prior to checking the oil level,
place the tractor on a flat horizontal ar-
ea. Shut down the engine and engage
the parking brake.
Check the oil level against the oil gage
(1) on the left side of the hydraulic sys-
tem tank. The level shall be between the
marks “О” and “П” (Full). If necessary, fill
up oil to the mark “П”, having taken the
rubber plug (2) away.
NOTE: When using the machines re-
quiring large amount of oil taking, add
oil to the level corresponding to the
upper mark “С”. When doing this, the
hydraulic cylinders shall be with plung-
ers indrawn.
Action 4. Draining the condensate
from the pneumatic system bottle
To remove the condensate from the
pneumatic system bottle, pull the ring (1)
of the drain valve horizontally and down.
Action 4а. Checking the oil level in the
hydrostatic power steering (HPS) tank
(MTZ-900.3/920.3/950.3/952.3)
Prior to checking the oil level, place the
tractor on a flat horizontal area. Shut
down the engine.
NOTE: To get access to the HPS tank,
lift the engine facing upwards to the stop
and fix it reliably in lifted position.
Check oil level in HPS oil tank against oil-
measuring rod (1). The oil level shall be
between the upper and lower marks of
the rod. If necessary, take the cap (2) of
the filler neck away and add oil to the up-
per mark on the oil-measuring rod.
