Waste Disposal - JMA Berna Instruction Manual

llowing steps:
4. remove the shavings tray.
5. turn the machine over so you can access the bottom.
6. unscrew the 4 nuts (t) holding the Motor to the bench. See Figure 18.A
7. turn the Machine bacK the right waY uP and reMoVe the Motor. See Figure
18.B
8. disconnect the motor connector.
9. remove the small pulley by unscrewing the nut (P).
10. take the new motor and mount the pulley.
11. Place the new motor with the screws in the right place on the bench. remember that
the legs have to be supporting the (u) screw heads at the bottom and the (w) screw head at
the side, so that the motor is in the exact position for screwing down. this leaves the motor
straight and in the exact position for correct alignment of the belt.
12. tighten the 4 screws (t) in this position.
13. re-connect the motor connector to the new motor.
14. Perform steps 9 to15 of chapter 4.7 to replace the belt and mount all the shields.
4.9 RePLACING THe MOTOR CAPACITOR
Proceed as follows:
1. turn the machine off and disconnect the power cable.
2. unscrew the 2 screws (F) to remove the cutter shield. remove the led strip.
3. unscrew the 10 screws (g) holding the motor protector (remember to remove the mat) and
remove the motor protector. see Figure 19.a
4. Unscrew the 4 screws (14) fastening the "terminal box" lid and remove it.
5. disconnect the two cables from the old capacitor (c) and remove it. see Figure 19.b
6. Mount the new capacitor (c) and connect the two cables.
7. Replace the "terminal box" lid and screw down with the 4 screws (14).
8. replace the motor protector and fasten it in with the 10 screws (g). replace the mat.
9. replace the cutter protector and attach it with the 2 screws (F).
4.10 ACCeSSING INSIDe THe CARRIAGe
For any maintenance operation that requires access to the inside of the carriage, perform the
following steps:
1. turn the machine off and disconnect the power cable.
2. remove the shavings tray.
3. release the carriage by pressing the button (M) and moving it towards the cutter-probe,
until the carriage reaches its limit.
4. unscrew the carriage control lever (P) and remove it.
5. Unscrew the 4 screws (15) fastening the "carriage box" and remove it
See Figure 20
4.11 TIGHTeNING THe CARRIAGe SPRING
Proceed as follows:
1. turn the machine off and disconnect the power cable.
2. access inside the carriage as described in the previous section (4.10).
3. use two nº4 allen keys to unscrew the two spring tensor (18) set screws (17): unscrew one
of the two set screws. then, use one of the allen keys to unscrew the second set screw, while
the second allen screw is used to support the tensor (18) to avoid it turning suddenly when
the second set screw is released.
4. with the allen key in the set screw (17), turn the tensor (18) until the desired force is achie-
ved. block the tensor (18) in this position using the two set screws (17).
See Figure 21
4.12 RePLACING THe MICROSWITCHeS
Proceed as follows:
1. turn the machine off and disconnect the power cable.
2. release the carriage by pressing the button (M) and moving it towards the cutter-probe,
until the carriage reaches its limit.
3. remove the shavings tray.
4. turn the machine over to access the bottom.
5. release the microswitch lid (19), which is found in the lower section of the carriage. uns-
crew both screws (20). See Figure 22.A
6. Move the carriage to the left and use a nº3 allen key to release the 2 screws (21) to release
the microswitch. See Figure 22.B
7. disconnect the cables from the old microswitch having noted down their position.
8. reconnect the cables to the new microswitch.
9. Mount the microswitch, fastening it in using the two screws (21).
10. replace the microswitch lid (19) and attach it with the 2 screws (20).
11. turn the machine over so that it's ready to use.
12. raise and lower the carriage to ensure that the microswitches function correctly.
13. Mount the shavings tray on the machine
5.- SAFeTY
For your safety, we recommend that you follow these guidelines:
• Do not try and start or operate the machine until all the safety aspects, installation ins-
tructions, operators' guide and maintenance procedures have been complied with and un-
derstood.
• Always disconnect the mains electricity supply, before carrying out any cleaning or main-
tenance work.
• Always keep the machine and the area around it clean.
• Work with dry hands.
• Always use protective goggles, although the machine is fitted with guards.
• Make sure that the machine has an earth connection

6.- WASTe DISPOSAL

waste is understood to be any substance or object from human activities or natural cycles,
that is no longer being used or not intended for any further use.
6.1 PACKING
• As the packing the VIENNA comes in is made of cardboard, it can be recycled as packing.
• As waste, it is comparable to solid urban waste and, therefore, can only be disposed of in
special containers for cardboard.
• The elements protecting the machine inside the cardboard box are made of polymeric ma-
terial comparable to solid urban waste and, therefore, can only de disposed of in the normal
installations for waste disposal.
6.2 SWARF
• The waste from the key cutting process is classified as special waste, but is comparable to
solid urban waste, like for example a metal scouring pad.
• This waste shall be disposed of as classified by the laws currently in force in the EU, by
taking it to special installations for waste disposal.
6.3 MACHINe
• Before demolishing the machine it is necessary to first put it out of action, cutting off the
electricity supply and separating the plastic parts from the metal parts.
• After carrying out this operation, all the waste can be disposed of in compliance with the
laws in force in the country in which the machine was used.
