Proxima.
Despite the fact that many of you have rich experience with operation of other tractors, please read carefully this
manual. You can find here new information and good advices how to use the best the tractor with various works.
When following these principles of operation and maintenance of the tractor and safety of driving, your tractor will
become reliable partner for years.
We wish you thousands of contented worked off hours.

COOLING SYSTEM
Check tightness of joints of the engine
cooling system and amount of cooling
fluid in the expansion tank that is installed on the right side of the engine
and accessible after lifting of the front
bonnet.
Refill the fluid up to the upper line
marked MAX. the minimum permissible
level of the cooling fluid is at the line
marked MIN.
Open the overpressure lid after
the fluid is cooled down! Danger
of scalding!
FLUID BRAKES
Check tightness of fluid brakes, fluid control of the clutch a amount of brake fluid
in the expansion tank that is installed on
the left side of the tractor in front of the
cab and accessible after lifting of the
front bonnet.
Keep level of the brake fluid between 3/4
(max. level) and 1/2 (min. level) of the
tank.
When handling with the brake
fluid, keep strictly all components
clean. Check level of the brake
fluid daily before driving.
AIR CLEANER
Maintenance of the cleaner shall
be carried out after indication of
clogging.
The indicator is accessible after lifting of
the front bonnet. It is installed on the left
side of the air cleaner, close to the elbow
of the air supply pipe.

OIL TANK OF HYDROSTATIC
STEERING
Using the gauge rod check level of oil in
the hydrostatic steering tank. The tank is
installed in the front left part of the tractor
and accessible after lifting of the front
bonnet.
Using the gauge rod (A) check level of oil
in the tank of hydrostatic steering; keep
the level between lines marked MIN. and
MAX., see Fig. (A).
Refill oil as necessary, do to it, remove
the nut (1) and lid.
Check condition of all hoses of the hydraulic steering circuit for possible damages and leakage of oil.
Check tightening of all bolts and nuts of
steering rods and levers.

TILTING STEERING WHEEL
The tilting column of the steering wheel
enables variable adjustment of height and
angle position of the steering wheel.
Height adjustment of the steering
wheel
Adjustment is carried out by extraction or
retraction of the steering wheel after
unlocking of the arrestment by turning of
the lever (1) in direction of the arrow. After
adjustment the lever (1) shall be locked by
tightening of the lever against direction of
the arrow.
Angle adjustment of the steering wheel
Adjustment is carried out by tilting of the
steering wheel after unlocking of the arrestment by turning of the lever (2) in direction of the arrow. After adjustment the
lever (2) shall be tightened against direction of the lever.
AGGREGATION HOLE, REAR RIGHT
PANEL
The lower window is fixed, with a hole for
connection of controllers of the aggregated implement (1).

MULTI-STOREY QUICK-ADJUSTABLE
HITCH CBM
It is used for hitching of two-axle of light
single-axle trailers. The guide mouth is
height-adjustable. When working with
various agriculture machines the height
of the hitch shall be adapted as necessary or dismount at all.
HEIGHT ADJUSTMENT AND
DISMOUNTING OF THE MULTISTOREY HITCH CBM
Turning of the lever in direction of the arrow to the position (1) unlocks the lever
and its subsequent turning to the position
(2) slides the arrestment pins (3) in; this
releases the multi-storey hitch and its
height can be adjusted or the hitch dismounted.
Release of the lever from the position (2)
slides the arrestment pins (3) out and the
lever returns automatically to its initial
position.
