5.1.1. Control panel
Controller (Fig. 9) 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. Note: 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.

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.
NOTE:
Telescopic articulated shafts should be mounted with wide-angle joint on the
rake side.

 make sure there is no person around the danger area where the machine is to be lowered,
 lower rake's arms by means of hydraulic lifter as slow as possible in order to better absorb it
when touching the ground,
 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 730, 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).

Before commissioning of the rake, in driving wheels (Fig. 17), replace provisional bolts (S)
on joints of steering heads with rear wheel axis for expansion pins Ø16 and Ø10 (K) delivered with
the machine. Install the pins as shown in Fig. 16.

Fig. 17. Preparing drive system of the rake
The following should be performed in workplace and as rake is in working position:
 connect PTO shaft extension onto tractor's spline shaft (if only one extension was taken out) or
connect the complete PTO shaft,
 set the tractor and rake aggregate on an even, level ground,
 lift or lower adjustment lever (Fig. 18) to set the required raking height. Recommended distance
of raking tines and the ground is 10 mm (Fig. 21).
Fig. 18. Raking height adjustment lever
NOTE!
It is forbidden to lower raking arms below 1 cm from the ground as this may
cause damages to the machine such as bending the raking arms, breaking the
linkage or the gear, faster wearing of raking tines, damaging the turf and
causing contamination to the collected forage, etc. Too high a raking set may
cause the swath not be collected completely.
NOTE!
The raking arms' height should be controlled on an on-going basis while
operating the machine, and if need be, adjusted. Adjustments are performed
with tractor's drive off.
