Changing The Cutter; Changing The Brush - JMA ECCO-AUTOMATIC Manual De Instrucciones

3.2.2 Copying a key without a stop
• Introduce the two wedges (2) into one of the ver-
tical grooves (R) of each clamp, depending on the
length of the key to be copied.
• Support the tips of the keys against the wedges (2).
The keys will thus be adjusted.
• Finally, press the clamps and withdraw the wedges (2).
• Before starting the cutting cycle, check that the
start of the notching of the key is to the right of
the tip of the feeler (to make sure that all the
teeth of the key will be reproduced), and that the
head of the key is to the left of the tip of the feeler
(to make sure that there will not be an undesired
collision between the head of the key and the tip
of the feeler).
3.2.3 Copying a cruciform key
• This type of key is copied on side 1 of the clamp.
• The keys must always be introduced into the
clamps from left to right.
• Introduce the two wedges (5), with the opening
or rebate facing upwards, into one of the vertical
grooves (R) of the clamp, depending on the length
of the key to be copied.
• Support the tips of the keys against the wedges (5).
The keys will thus be adjusted.
• Finally, press the clamps and withdraw the wedges (5).
• The cutting of the key is carried out in three ope-
rations, turning and supporting each time the stop
of the key against the wedge (5).
• Before starting the cutting cycle, check that the
start of the notching of the key is to the right of
the tip of the feeler (to make sure that all the
teeth of the key will be reproduced), and that the
head of the key is to the left of the tip of the feeler
(to make sure that there will not be an undesired
collision between the head of the key and the tip
of the feeler).

4.3 Adjusting the depth of the slide
See figure 12
This adjustment serves to protect the clamps from possible
collisions between the feeler and the cutter.
The distance between the cutter-feeler and the clamps
should be about 0.15 mm. If this distance is changed, pro-
ceed as follows:
• Unblock the slide and bring the clamps near to the
feeler and the cutter. In order to do this, follow the
steps below:
- Place any key in the left-hand clamp and start the
