BELARUS Seat
Important! Prior to starting the work on
the tractor, adjust the seat to the position
being the most convenient for you. Per-
form all the adjustments while sitting on
the seat.
The seat is considered to be adjusted
correctly to the operator’s weight, if it
takes up half of its travel under the op-
erator’s weight (suspension travel: 100
mm).
Seat adjustment:
To the operator’s weight: from 50 to
120 kg.
It is performed by means of the handle
(1). To adjust the seat to a heavier
weight, it is necessary to reset the pawl
of the handle (1) to the position “ А ” and
to tighten the springs by reciprocating
motion. To adjust the seat to lighter
weight, it is necessary to reset the pawl
to the position “B” and loosen the
springs by reciprocating motion.
Back inclination adjustment: from 15°
to 20°. It is performed by means of the
handwheel (2). To increase the back in-
clination angle, it is necessary to turn the
handwheel clockwise, and to reduce the
same – counter-clockwise.
Longitudinal adjustment of the seat:
160 mm. It is performed by means of
the handle (3). To move the seat for-
ward or backward, it is necessary to lift
and pull the handle, shift the seat and
release the handle. The seat will be
fixed automatically in the required posi-
tion.
Height adjustment 60 mm. The seat
has three height positions: “bottom”,
“medium” and “top”. To transfer the seat
from the “bottom” position to the “me-
dium” one or from the “medium” to the
“top” one, it is necessary to lift smoothly
the seat until the operation of the click-
work (the characteristic click is heard).
To transfer the seat from the “top” posi-
tion to the “bottom” one, it is necessary
to lift the seat up to the stop and in an
abrupt movement and then drop it.
Note: It is impossible to transfer the
seat from the “medium” position to the
“bottom” one.
“Reverse” position (for BELA-
RUS- 1523В/1523В.3 tractors with re-
versible control post) To transfer the
seat to the “reverse” position, it is neces-
sary to turn out the clamps D and lead
them out from the slots of the brackets of
the panel E, lift the lever F and turn the
seat by 180°. Lift the seat and pull it in an
abrupt motion. Lead the screws G into
the slots of the brackets of the panel E,
turn on the nut I until it rests against the
brackets and tighten the clamps I with
the torque of 44 … 56 Nm.
