Controller (Fig. 8) enables switching the rake's working units to working position (lowering)
and transport position (lifting). During the machine operation, if diode (1) is lit the sequential lifting
and lowering of working units function is enabled. Button (C) is for switching between the panel
functions. Once button (C) is pressed the diode (1) goes off, a diode (2) will light up to indicate
deactivation of sequential lifting and lowering function and thus activation of folding the machine
for transport and unfolding it for operation function. Once this option is enabled the working units
will fold and unfold steadily.
CAUTION: once diode (2) lights up the function remains active for 60 seconds. This time is
sufficient to fold the machine to transport position or unfold it to working position. As the 60 s time
elapses the panel will go to sequential operation mode.

5.2. Preparing rake for transport
CAUTION!
Exercise particular caution when mounting rake on vehicle. During mounting
make sure there are no people between the rake and the tractor.
NOTE
Mount the machine on a level ground.
In order to prepare the rake for transport (drive on a road):
 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 out the extreme most raking arms from a rotor, place them in transport holes (depending on
max. height of obstacles under way) (Fig. 9),
 lift working assemblies and secure them with a pawl (P) (See point 5.10. Lifting rake on
headlands and transport position),
 lower and secure a support leg,
Fig. 9. Transport dimensions
CAUTION:
Once the machine is set to transport position, check whether mechanical
locking pawls (P) are properly locked on pins (Fig. 10).

5.3. Preparing rake for transport on public roads
To meet safety precautions concerning transport on the public roads the rake should be
equipped with warning triangle, attached at the rake's rear (the plates are standard-delivered with
the machine.) To improve safety during the transport the machine should be fitted with a warning
triangle – to be purchased at the manufacturer.
When transporting on public roads respect provisions valid in the country of use.
NOTE:
If the rake's owner does not own the above warning lights and plates, these can be ordered at
the manufacturer.
5.4. Mounting telescopic articulated shaft
Mount the shaft with wide-angle joint from the rake side.
The guard should be protected against rotating by securing the shaft set chains to immovable
parts of the tractor and the rake.
Prior to commencing operation, examine and adjust length of PTO shaft, which is designed to
mount machine on tractor. In some cases it is possible, that the shaft is too long and therefore needs
to be shortened, so that there is adequate tolerance for the shortest possible distance between
tractor’s shaft and machine’s shaft.
Shaft's length should be adjusted individually for the tractor, on which the machine is
mounted.
NOTE:
If need be shorten the shaft as provided in the corresponding operator's manual (Fig. 11).

CAUTION:
The telescopic articulated shaft should remain mounted only during the rake's
operation period. For transport and service time the shaft should be
disconnected from the tractor's PTO shaft.
CAUTION:
Use machines with correspondingly designed telescopic articulated drive
shafts. Prior to work commencement, inspect safety guards whether they (in
tractor, machine and shaft) are placed correctly and are not damaged.
Damaged or missing parts must be replaced with genuine ones. Make sure
that the telescopic articulated shaft is mounted properly. Approaching the
rotating parts is strictly forbidden, as it may lead to serious injuries or even
cause death. For any service and repair works of the shaft and the machine,
the tractor engine and spline drive must be disconnected. Prior to the
operation commencement, read the operator's manuals of both the machine
and the shaft.
5.5. Switching the rake from transport to working position
 Make sure there is no person around the danger area where the machine is to be lowered.
 Unlatch the locking pawls (P) by means of cord (4) (Fig. 10).
 By control panel - function (2) (Fig. 8) – and hydraulic lifter, lower rake's arms to working
position.
 If raking tines were demounted, remove raking arms from transport holes, mount them in the
rotor and secure with cotters.
 Lower safety guards.

5.6. Preparing rake for operation
NOTE:
For the machine storing period, cylinder rods are lubricated as SaMASZ with protective
grease in order to protect them against weather conditions able to shorten their service life.
Prior to start operating the machine remove excess grease coming out from cylinder rods.
Due to large dimensions of rake TANGO, extreme most 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:
 unscrew bolts from rake's arms on each gear (Fig. 13),
 support rake's arm to avoid damaging the gear's connecting rod (Fig. 14),
Fig. 13. Temporary mounting of arms Fig. 14. Supporting rake arm
 hammer expansion pins into holes where bolts were previously placed. put pin Ø10 and Ø6 into
each one hole (Fig. 14).
