5.5) With the two adjustment rods inserted in holes no. 1, block the head, and
slightly tighten screw B.
5.6) With the two adjustment rods inserted in holes no. 2, block the head and
slightly tighten screw A.
5.7) Repeat the above operation, but fully tightening screws A and B.
5.8) Once you have completed the adjustment process, with the help of the special
short-arm 1.5 Allen key, tighten the two setscrews located between the clamp
knob and the jaw you have adjusted. This will ensure that the jaw you have adjus-
ted is tightly secured.
6.2.2 PRECISION ADJUSTMENT
This adjustment requires a certain amount of skill, and ensures that the replaced jaws
are very precisely adjusted.
To carry out this adjustment, follow these steps:
Switch off the machine using the main switch and unplug it.
1)
The left fixed jaw on the right-hand side of the clamp and the right fixed jaw on the
left-hand side of the clamp cannot be adjusted, as they are held in position by means of
pins. So you have to fit them, by guiding them with their pins and then securing them
with their corresponding screws.
2)
Therefore, knowing that in each pair of jaws there is one with a fixed position, you
have to adjust the other jaw in relation to the one with the fixed position.
3)
Insert the screws for the jaw to be adjusted, but do not tighten them. So that the
jaw can be moved by hand, but cannot lift up from the surface it is resting on.
4)
With the help of the special short-arm 1.5 Allen key, unscrew the two jaw adjust-
ment setscrews about 1 turn (these are the two setscrews located between the clamp
knob and jaw you are going to adjust).
5)
Then, insert any cutter-tracer point pair in their corresponding tool-holders, but
the wrong way around (with the cutting tips inside the tool-holder). Lower the machine
head, and block it at a height at which the tools can touch the sides of the jaws.
6)
Activate the tracer point electronic vertical adjustment system.
7)
Rest the end of the jaw that is clamped (the one with the fixed position) against
the side of the tool. Manually, move the jaw to be adjusted in the direction of the clamp
knob, and maintaining pressure on the jaw in that direction, move it forward until it also
touches the side of its corresponding tool. In this position, tighten the screws securing
the jaw a little. You will know when the tools are touching their corresponding jaws,
because the tracer point electronic vertical adjustment system's lights will come on.
8)
Then, separate the moving jaw from the jaw to be adjusted, turning the clamp knob
to do so.
9)
Position the tool in alignment with one of the screws securing the jaw, and in
this position rest the tool against the jaw that is clamped (the one with the fixed po-
sition). Then, keeping at all times a slight pressure between the tool and the jaw that
is clamped (the one with the fixed position), very slowly tighten the setscrew aligned
with the tool and the jaw screw. The moment will come when the second light on the
tracer point electronic vertical adjustment system will come on. When this happens,
stop tightening the setscrew.
10) Position the tool in alignment with the other screw securing the jaw, and carry out
the same operation again.
11) Check again that the jaws are adjusted in those two positions (in front of the
clamping screws), and if necessary, slightly adjust the position of the jaw tightly very
slightly the corresponding setscrew.
12) You have now completed the adjustment. Now you have to fully tighten the two
screws securing the jaw.
13) Finally, tighten the two jaw adjustment setscrews a little. This will ensure that the
jaw you have adjusted is tightly secured.
6.3 REPLACING THE FUSES
If the machine does not start when you activate the on-off switches, you need to check
the fuses. You can do this in the following way:
Switch of the machine using the main switch and unplug it.
1)
Remove the fuse-holder which is under the main switch.
2)
Use a tester to check if a fuse has blown and, if so, replace it with one of the same
type and value.
6.4 TIGHTENING AND REPLACING THE BELT
To check the tightness of the belt or to replace it, follow these steps:
Switch off the machine using the main switch, and unplug it.
1)
Undo the 4 screws (5) securing the head guard and remove it. The screws are on
the right side, the left side, on the top and at the back. To remove the head guard it is
necessary first of all to push the cutter locking button right in as far as it will go (E).
2)
Loosen but do not undo the 4 screws (6) securing the motor.
3)
Loosen but do not undo the 2 locknut nuts (7).
Tightening: When you turn the two tightening screws (8), the motor moves towards
the back of the machine. When you see that the belt is tight enough, tighten up the two
locknut nuts (7) again, and the screws (6) securing the motor.
Replacement: Loosen but do not undo the 2 screws tightening the belt (8). Remove the
damaged belt and replace it with a new one. When you turn the two tightening screws
(8), the motor moves towards the back of the machine. When you see that the belt is
tight enough, tighten up the two locknut nuts (7) again, and the screws (6) securing
the motor.
4)
Put the head guard back and secure it in place.
