Replacing The Fuses; Replacing The Motor - Errebi DAKAR EVOLUTION Manual De Instrucciones

4.2.2 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:
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 ad-
justment 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 position).
Then, keeping at all times a slight pressure between the tool and the jaw that is clam-
ped (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.

4.3 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:
1) Switch of the machine using the main switch and unplug it.
2) Remove the fuse-holder which is under the main switch.
3) use a tester to check if a fuse has blown and, if so, replace it with one of the same
type and value.
4.4 TIGHTENING AND REPLACING THE BELT
To check the tightness of the belt or to replace it, follow these steps:
1) Switch off the machine using the main switch, and unplug it.
2) 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).
3) loosen but do not undo the 4 screws (6) securing the motor.
4) 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.
5) put the head guard back and secure it in place.
See Fig. 18

4.5 REPLACING THE MOTOR

You can carry out this operation in the following way:
1) Switch off the machine using the main switch and unplug it.
2) 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).
3) undo the 6 screws (9) securing the motor guard (F) and remove it.
4) Remove the belt (G).
5) Disconnect the power cables going to the motor.
6) undo the 4 screws (6) securing the motor.
7) Remove the motor.
8) access the bottom of the motor with a flat screwdriver, block the motor shaft and
manually turn the pulley (h) until it comes out (it is left-threaded).
9) undo the 4 screws (10) securing the motor support plate and remove it.
10) To fit the new motor, reverse the procedure above.
See Fig. 19
4.6 REPLACING THE KEYBOARD-DISPLAY
You can carry out this operation in the following way:
1) Switch off the machine using the main switch, and unplug it.
2) 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).
3) Disconnect the flat cable connecting the keypad-display (K) to the electronic con-
trol card.
4) Release the old keypad-display (K) from the head guard and remove it.
5) To fit the new keypad-display, reverse the procedure above.
