5.5 MACHINE USE FOR THE SIMULTANEOUS BRAKING OF RIGHT AND LEFT BULL-
WHEELS
a) Connect right and left bull-wheels by the suitable pin (table 6).
b) Move the selector (table 4, pos. 22) towards left.
c) Move the selectors (table 4, pos. 38,39) towards left.
d) Move the selectors (table 4, pos. 13, 17) towards position (BLOCKED).
e) Move the selector (table 4, pos. 35) towards position (BLOCKED).
f) Move the selector (table 4, pos. 17) towards position (FREE).The selector (table 4,
pos. 3) is disabled.
g) Move the selector (table 4, pos. 17) towards position (FREE).
Now the bull-wheels can rotate freely.
h) Use the potentiometer (table 4, pos. 16) to brake right and left bull-wheels.
This potentiometer controls the two circuits while the other potentiometer (table 4, pos. 12) is not
connected.
The circuits' pressure, proportional to the pull, can be read on the manometers (table 4, pos. 14,18).
The cables tension can be read by a suitably graduated ring nut mounted outside them.
PROHIBITION: is not possible to low or lift the joystick (table 4, pos. 11) from central
neutral position and move the selectors (table 4, pos. 38, 39) rightwards, in this phase .
Can damage seriously the machine.
5.6 MACHINE USE FOR SIMULTANEOUS BRAKING OF SIX BUNDLED CONDUCTORS
Stringing operations for six bundled conductors can be carried out using two machines with coupled
capstans:

Load three conductors on bull-wheel 1 and 2 on the Master machine; and load three conductors
on the capstans 1 and 2 on the Slave machine (see tab. 9.1) .

Proceed as per point 5.5 making care to set with capstan 1 and 2 a braking value a triple pull
respect to a single one.

In this configuration, it is necessary to use a balancing head board, suitable for stringing
operations, with balance on conductors 1-3 and 4-6 (2 and 3 fixed).
5.7 MACHINE STOP
To stop the machine after the use as tensioner and after the stop of the puller, act as follows:
a. turn the potentiometers (table 4, pos. 12,16) in clockwise direction till the bull-wheels stop.
b. move the selectors (table 4, pos. 35) towards position (BLOCKED) to lock the bull-
wheels. Before carrying out this manoeuvre it is better to wait to the bull-wheels stop if it is not an
emergency intervention; in this way the vacuum brakes damage is avoid.
NOTE: if the Diesel engine stops for unknown reasons, the vacuum brakes
automatically lock. Before restarting the Diesel engine, move the selectors towards
position (BLOCKED) (table 4, pos. 35).
