Gearbox oil pump control
The gearbox oil pump control lever (1)
can have two fixed positions:
I — “Pump drive from engine” (normal
operating position) — the lever
(1) is turned counterclockwise
(when looking at GB from the left
tractor side) relative to the axis
(3) until the lower edge of the
lever slot stops and is fixed by the
bolt.
II — non-working position.
Important! Set the lever (1) in the po-
sition II when there is a necessity to
remove and to mount the assembled
GB pump drive (4) and then fix the
lever (1) in the position I again.
Hydraulic system distributor control
Each of the three remote levers (1, 2,
3), controls the remote cylinders and
has four positions:
•
“Neutral” — low middle (fixed);
•
“Lift” — low (non-fixed); after releas-
ing the lever returns to “neutral";
•
“Positive lowering” — upper middle
(non-fixed) between the “float” and
“neutral”. After releasing the lever
returns to “Neutral";
•
“Float” — upper (fixed)
