HOW TO LOCK THE SWIVELLING BLADE
When the cable has to be laid over long straight sections, it is
possible to lock the swivelling blade (fig.12) to ensure greater
precision of the machine direction. To lock the blade, it suffices to tighten the handle
placed on the right side of the support apparatus (fig.12 n.1).
Fig. 12
HOW TO ADJUST THE WIDTH OF THE WHEELS
Both wheels are equipped with 4-position adjustable drive shafts.
This system offers the possibility to position the cutter
at 25, 27, 29 o 31 cm from the adjustable edge.
(fig.13). This allows laying the cable at equal distance
from any edge, wall or hedge. To adjust this
distance, pull out the locking pin (fig.13 n.2), position it
in one of the 4 holes provided on the drive shaft (fig.13 n.1) and
lock back the safety spring.
HOW TO START WORKING
