Operating Manual; First Start; Preparation Of The Unit (Tractor + Machine) - UNIA ARES L series Operating And Maintenance Manual

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

3.2 Preparation of the Unit (Tractor + 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!
