3. Operating Manual
3.1 First Start
Before the first start of the machine:
• read the Operating Manual thoroughly
• check technical condition of the machine, and in particular, condition of its
working parts, protecting mechanisms and the hydraulic system. When finding
any damaged or worn parts, replace them with new ones
• check tightening of all screws, bolts and nuts. Tighten any loose nuts especially at
the beginning of operation of the machine
•
the tightening torque of the nut of the replaceable
hub is
300 Nm , in order to extend the service life of
the bearings it is necessary to systematically check
this value during machine operation, and also when replacing
elements
•
check fitting of the quick-connectors of the hydraulic hoses of the
machine to the sockets on the tractor
•
check, whether the disc coulters, rollers and spindles (turnbuckles)
can rotate without any jams
•
check the pressure in tyres acc. to the manufacturer’s
recommendations (if any)
•
check, whether the components requiring lubrication are
lubricated
•
check, whether the machine attachment system fits the tractor
attachment system

hub
3.2 Preparation of the Unit (T Machine)
•
pressure in the tractor wheels must be equal on the same axle in order to
provide uniform working depth of the machine
•
the tractor lower links (c) must be stiffened (lock the oblong holes) and at
the same height above the ground level
•
set the lifting rods of the tractor links (w) so that you can pull down the
lower links below the hitch axle in order to achieve the required working
depth, while obtaining sufficient lifting height of the links for transport
•
mount the front axle weights in order to keep balance of the tractor and
the machine
•
quick-connectors of the machine hydraulic hoses must fit the sockets on
the tractor
•
the hitch axle should be in the middle of the machine
•
category of the lower articulated joint of the hitch axle must be the same
on both the tractor and the machine sides!
