7.2) Assembly of the DBG-Y clamping device on the drill
The DBG-Y clamping device is fi tted to the front plate of the drill, centred by means of the
reference pin supplied and secured with the two socket head cap screws M8x25 (35) also
supplied. The assembly is illustrated in Fig. 14.
FIG. 13 – ASSEMBLY OF THE TERMINATION
7.1) Assembling of the termination of the DBG-Y device with moving arm for clamping
the drill to the rail web and track fi ttings.
The termination TDB 6 of the DBG-Y device, with moving arm, have been designed for
adaptation to the different operating conditions on the rails and track fi ttings; their assembly
is shown in Fig. 13.
•
When disassembling the TD termination ensure that, after removing the pivot, the
complete assembly is slid away downward without acting on the holding plate.

Switch on the cooling system before starting the rail drill (§ 4).
8.1) Rail drill fi tted with “short” type broach cutter (depth of cut 7/8")
The drilling sequence may be started with the drill fi tted with the broach cutter (§ 6.1),
positioning shoe (§ 7.3), the drill being clamped to the rail (§ 7.4), as follows:
8.1.1) Connect the female quick-coupling of the SR5000 coolant system to male coupling
(35) on the drill.
8.1.2) Open the tap (02) fi tted on the tank tube.
8.1.3) Using the lever (36) bring the guide bit almost in contact with the rail (Fig. 17a);
keeping the release pawl (39) pressed, release the lever from its cup and return it to the
initial position (Fig. 17b), which will enable the travel of the lever (36) to be used in the
most advantageous way.
8.1.4) Connect the electric plug and press the automatic switch (position "I") (Fig. 18)

CAUTION: the automatic switch is equipped
with protection against motor overheating and with
an underpower relay; should the motor overheat or
there is a fall in voltage below the relay cut-out set-
ting, the switch will move into the "0" position. At
this stage, if the conditions are correct, the switch
will have to be re-set manually.
