To protect the metal parts of the machine against oxidation, it is recommended
to use protective oil of the type WD40 or similar, applying it on clamps, tracers,
guides, etc...
6.1 BRUSH REPLACEMENT

2) Insert the securing rod into the hole in the brush assembly.
3) Using the 5 mm Allen key, release the screw holding the brush in place.
4) Replace the brush and secure it in place.
5) Remove the securing rod and reattach the cutter and brush protector.
See figure 12
6.2 CUTTER REPLACEMENT
The cutter should be replaced when it becomes worn. Do so as follows:
Switch off the machine and unplug the power cord.
1) Release the 4 screws securing the cutter and brush protector and then remove it.
2) Insert the securing rod into the hole in the cutter assembly.
3) Using the 5 mm Allen key, release the screw holding the cutter in place. Bear in mind
that this is a reverse-thread screw.
4) Carefully clean the new cutter and all areas that will come into contact with it.
5) Replace the cutter and re-secure it using the reverse-thread screw.
6) Ensure that the cutter is securely in place and facing the correct way (it rotates clockwi-
se).
7) Remove the securing rod and reattach the cutter and brush protector.
8) After replacing the cutter, the depth adjustment process should be repeated. The steps
to do so are explained in Section 3.1.
See figure 13
6.3 PROBE REPLACEMENT
The probe should be replaced when it becomes worn. Do so as follows:
Switch off the machine and unplug the power cord.
1) Release the screw (S) using the 3 mm Allen key.
2) Rotate the control wheel (W) until the probe (T) is fully removed.
3) Insert and secure the new probe, ensuring that the flat side is facing upwards.
4) After replacing the probe, the depth adjustment process should be repeated. The steps
to do so are explained in Section 3.1.
See figure 14
6.4 CARRIAGE DEPTH ADJUSTMENT
A maximum cutting depth should be set in order not to damage 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 machine and unplug the power cord.
1) Raise the carriage and move the clamps towards the cutter/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
6.5 INTERIOR ACCESS
For maintenance requiring access to the machine interior, do the following:
Switch off the machine and unplug the power cord.
1) Very carefully roll the machine onto its rear side.
2) Remove the 4 feet. Loosen the 4 screws (Q) to do so.
3) Remove the lower casing. Remove the screw (O) to do so.
See figure 16
6.6 FUSE REPLACEMENT
If the machine fails to start when pressing the on/off switch, the condition of the fuses
should be checked. This is done as follows:
Switch off the machine and unplug the power cord.
1 Remove the fuse holder at the rear of the machine, next to the power cable socket.
2) Check whether the fuse has blown. If necessary, replace the fuse with another of the
same type and value
See figure 17
6.7 ON/OFF SWITCH REPLACEMENT
This is done as follows:
1) Access the interior of the machine as indicated in Section 6.5 of this manual.
2) Squeeze the tabs on the switch to remove it.
3) Disconnect the wires from the switch, noting down the position of each one beforehand.
4) Connect the wires to the new switch.
5) Squeezing the tabs on the switch, fully re-insert it back into the housing.
See figure 18
6.8 BRIDGE RECTIFIER REPLACEMENT
This is done as follows:
1) Access the interior of the machine as indicated in Section 6.5 of this manual.
2) Disconnect the wires from the bridge rectifier (V), noting down the position of each one
beforehand.
3) Remove the screw (K) holding the bridge rectifier (V) in place.
4) Secure the new bridge rectifier (V) using the screw (K).
5) Connect the wires to the new bridge rectifier.
See figure 19
6.9 CIRCUIT BREAKER REPLACEMENT
This is done as follows:
1) Access the interior of the machine as indicated in Section 6.5 of this manual.
2) Disconnect the wires from the circuit breaker, noting down the position of each one
beforehand.
3) Remove the circuit breaker (M). Remove the screws (L) to do so.
4) Then secure the new circuit breaker in place using the screws (L).
5) Connect the wires to the new circuit breaker.
See figure 20
6.10 BELT REPLACEMENT AND TENSING
Follow the steps below to do this:
Switch off the machine and unplug the power cord.
1) Release the 4 screws securing the cutter and brush protector and then remove it.
2) Release the tensioning screw (Z) using the 3 mm Allen key.
3) Access the interior of the machine as indicated in Section 6.5 of this manual.
4) Use the 5 mm Allen key to slightly loosen the 2 screws (F) holding the motor (N).
5) Move the motor (N) so the two pulleys move closer together.
6) Remove the old belt. Remove it by moving it around the brush.
7) Fit the new belt and visually check that it is in place correctly.
8) TENSIONING THE BELT: By turning the tensioning screw (Z), the motor (N) will move
towards the bottom of the machine and the belt will consequently become more tense.
When you think the belt is tense enough, secure the motor (N) using the two screws (F).
See figure 21
6.11 MOTOR REPLACEMENT
Follow the steps below to do this:
Switch off the machine and unplug the power cord.
