5. OPERATION
5.1. Attaching the rake to the tractor
Rotary rake Z2-780 and Z2-840 works properly with tractors (class 2,0 and power from 60 HP).
The rake should be attached to a tractor with use of tractor's lower pull-cables as provided on
Fig. 7. For this purpose drive the tractor at the rake's catch, and then place hangers W of
tractor's lower pull-cables on pins S on the rake's linkage.
Once the rake is mounted turn support leg back.
Connect hydraulic hoses.
Connect the machine's lighting cables to the tractor and check the lights for operation.
Connect telescopic articulated shaft. If need be shorten the shaft as per item 5.4.

Fig. 7. Connecting the rake to the tractor
After the rake has been attached to tractor, check the balance and steerability of tractor - rake
set. In order to perform this, the tractor should be weighed and then driven onto the scales with the
tractor's front axis only (tedder must be in transport position, so lifted upwards). If the pressure on
the front axis is at least 20% of the whole set’s pressure, it means the set is stable. If not, the front
axis should be balanced.
5.2. Preparing the rake to transport
CAUTION:
Switching the machine from working to transport position, and the other way
round can only be done on an even and stable ground. Prior to starting any
works make sure that nearby the machine there are no unauthorized persons
exposed to being crushed.
To prepare the rake to transport and to meet safety precautions, please do the following:
due to safety reasons, before setting the rake to transport position turn off the PTO shaft; raking
arms cannot be in motion,
lift safety guards to transport position,
take off extreme rotors, put them in the transport holes, (depending on the maximum height of
the obstacles during transport),
lift support legs,
lift working assemblies and secure them with a pawl.

Double – sided rotary rake
Z2-780; Z2-840
CAUTION:
The PTO shaft should be mounted only during operation time and
disconnected from tractor PTO for transport and service.
CAUTION:
Use the machines with PTO shafts designed to drive them. Before the work
begins, check the safety guards (in tractor, rake and PTO shaft), if they are
placed correctly and are not damaged. Damaged or lost parts must be replaced
with genuine ones. Make sure the PTO shaft is properly mounted. It is
forbidden to approach the rotating parts, because it may lead to serious injuries
or even death. All service and repair operations must be done only after the
tractor engine has been stopped, all rotating parts have come to the complete
standstill and the cutterbar is on the ground. Before the operation begins, read
operator’s manuals of both the machine and PTO shaft.
CAUTION:
PTO shaft’s end with wide-angle join should be mounted on rake’s side.
5.5. Switching from transport to working position
make sure there is nobody around in the place where you are going to lower the rake,
unblock the locks with a cord,
by means of hydraulic lifting lower arms of the rake in the slowliest way in order to cushion
contact with the ground,
take off arms from transport holders, put them into the rotors and secure them with cotter pins,
lower safety guards.
5.6. Preparing the rake for work
CAUTION:
During storing of the machines in company SaMASZ the cylinders are
protected by special grease in order to secure them against weather which may
cause their premature wear. Before starting the operation excess grease should
be removed from the cylinders.
Due to large dimensions of rakes, 4 arms are originally dismounted on each rotor for transport
purposes (TIR). In order to dismount these quicker they are mounted in factory with bolts. For
operation purposes put expansion pins which are provided with the machine instead of factory bolts
as given below:
untighten bolts from four outer arms on the rakes in each of transmissions (Fig. 10),
support rake arm in order to avoid damaging transmission connecting rod (Fig. 11),
