out with the utmost caution. Have all persons not involved in the actual work move away from
the area and limit the zone where the operations are to be carried out. Also make sure that the
area in which the operations take place is clear and that there is a sufficient escape route, i.e. a
free, safe zone to which the operators can quickly move if the load should fall.
The safety hooks and ropes used to lift the machine must be of an adequate carrying capacity
To minimize the risk of serious injury or death, do the following:
 When the machine is converted from the transport position to the work position and vice versa,
you could be pinched or crushed by some of its parts. Take extra care when carrying out these
maneuvers and have all persons keep well clear of the danger zone.
 Do not change position of the rake until there are no people or animals around (pay particular
attention to children).
 While transporting the rake, put a warning plate with combined lights and reflectors and
warning triangle on the rake.
 During transport, always put the rake in its proper and safe transport position. See section 5.2.
 Before moving the rake in transport position, make sure that the tractor’s PTO is turned off and
all rotating parts have come to a complete stop.
 Do not drive over 30 km/h (17 mph). Drive slower if road conditions are poor, especially on
irregular surfaces or steep slopes.
 Before transporting the rake make sure that mechanical locking pawls are properly locked on
pins.
 Before transporting the rake make sure that support legs are lifted and protected.
 The behavior of the tractor on the road, such as its turning and braking capacities, are affected

- Make sure all safety devices are in place and working. Fix or replace if not
working or damaged.
- Replace protective cover if damaged.
5.1. Attaching the rake to the tractor
WARNING:
- Only hitch and unhitch machine on a flat surface with compact dirt.
- Keep everyone away from area between rake and tractor.
- Be careful near link road zone of tractor's rear power lift. Contains sharp
parts.
Rotary rake Z2-780 / Z2-840 works properly with tractors (class 2.0 and power from 60 HP).
 The rake should be attached to a tractor by means 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 Wof
tractor's lower pull-cables on pins Son 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 PTO shaft. If need be shorten the shaft as given in section 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 for transport
To prepare the rake for transport and to meet safety precautions, please do the following:
 for safety reasons, before setting the rake in transport position dismount the PTO shaft; raking
arms cannot be in motion,
 lift safety guards to transport position,
 remove outer 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 pawl.

CAUTION:
When lifting the machine for transport pay attention so that the tractor's glass
pane is closed. Protective barriers on the rake may damage the glass.
5.3. Preparing the rake for transport on public roads
WARNING:
Legal requirements for transport on public roads may differ from state to
state. Check your location's requirements and comply.
To comply with safety precautions concerning transport on the public roads the rake should be
equipped with the following devices:
 portable warning light plates to be mounted on both sides of rake top guard in their holders.
The panel consists of warning plate with combined lamp mounted (parking, stop lights and
driving direction) and with red reflectors facing the rear and white light on the front.
WARNING:
Do not drive on public roads if the machine's transport height is more than
4 m (14') (when transported, transport height should be lowered by
disassembling outermost the arms).
5.4. Mounting PTO shaft
PTO shaft’s end with overrunning clutch should be mounted on rake’s side.
When connecting PTO shaft between tractor and rake, make sure that external guard tube of the
shaft is on the tractor’s side. The PTO shaft plastic guards have to be secured by fastening their
small chains to immovable parts of tractor and rake. The PTO shaft must operate at the lowest
possible angle. This will ensure that both shaft and the machine last as long as possible.
CAUTION:
If need be, shorten the PTO haft according to its operator’s manual given by
the shaft’s manufacturer (Fig. 9).

Fig. 9. Instruction of PTO shaft shortening
NOTICE:
The manufacturer declines all liability for damage caused by an incorrectly fitted or used
PTO shaft.
CAUTION:
Handle all parts with utmost care. Never place your hands or fingers between
one part and the other. Wear safety clothes such as gloves, protective
footwear and goggles. The operation of shortening must be carried out with
the utmost care as the PTO shaft will have to be replaced if the telescopic
shafts are shortened to an excessive extent.
CAUTION:
The PTO shaft should be mounted only during operation time and
disconnected from tractor PTO for transport and service.
WARNING:
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 original 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 and ignition key removed, all
rotating parts have come to the complete standstill and the working unit is on
the ground. Before the operation begins, read operator’s manuals of both the
machine and PTO shaft.

5.5. Moving from transport to working position
WARNING:
Moving the rake to and from operating position from the transport position
should only take place on even and stable ground. Prior to making the moves
make sure whether there are no unauthorized persons exposed to any
hazardous moving parts.
To safely move to the operating position, do the following:
 make sure there is nobody in the place where you are going to lower the rake,
 using a cord, open the locks,
 by means of hydraulic lifting assembly lower the rake arms as slow as possible to absorb the
machine as it contacts the ground,
 remove the arms from transport holders, install them on the rotors and secure with cotter pins,
 lower safety guards.
5.6. Preparing the rake for work
NOTE:
For the period of machine storage at SaMASZ cylinders are covered with special grease in
order to protect them against weather conditions which may cause their premature wear.
Before operating remove the excess grease the cylinders.
Due to large dimensions of rakes, 4 arms are originally dismounted on each rotor for transport
purposes (to be put on vehicles). In order to enable their quicker dismounting 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 transmission gears (Fig. 10),
 support rake arm in order to avoid damaging the transmission gear connecting rod (Fig. 11),
