6.3 TRACER REPLACEMENT

The tracer should be replaced when it becomes worn. Follow
the steps below to do so:
Switch off the power switch (11), switch off the
master switch (15), close the protective screen (16)
and check that the machine is NOT connected to
the battery charger.
1) Release the screw (S) using the 3 mm Allen key.
2) Rotate the control wheel (W) until the tracer probe (T) is
fully removed.
3) Insert and secure the new tracer, ensuring that the flat
end is facing upwards.
4) The depth adjustment process should be repeated. The
steps for doing so are explained in another section of this
manual.
See Figure 14

6.4 CARRIAGE DEPTH ADJUSTMENT

A maximum cutting depth should be set in order not to da-
mage the clamps or the cutter.
The distance between cutter/probe and clamp should be 0.1
mm. Do the following if this is not the case:
Switch off the power switch (11), switch off the mas-
ter switch (15), close the protective screen (16) and
check that the machine is NOT connected to the
battery charger.
1) Raise the carriage and move the clamps towards the cut-
ter/probe as far as the carriage assembly will go.
2) Loosen the securing bolt (D) with the 8 mm wrench.
3) Adjust the screw (P) to achieve a separation of 0.1 mm.
4) Secure the screw (P) by tightening the bolt (D).
See Figure 15
