1.2 Intended Use

• The device is manufactured in accordance with the current technological status and the recognized safety rules.
However, danger to the life and limb of the user or third parties and/or damage to the device and other tangible
assets can arise during use.

• The device may only be used for its intended purpose and if it is in perfect working order, and it must be used with
regard to safety and dangers as stated in the operating manual.

• The device is intended exclusively for separating pre-scored PCB's. Any other use or use going beyond this
shall be regarded as improper use. The manufacturer/supplier shall not be liable for damage resulting from
unauthorized use; the user shall bear the risk alone.

• Usage for the intended purpose also includes complying with the operating manual, including the manufacturer‘s
maintenance recommendations and specications.

Notice!
The complete documentation can also currently be found in the Internet.

i

1.3 Safety Instructions

• Hazard by electrical charge. Provide an earthing connection via press stud.

• Risk of hand injury. Wear protective gloves while PCB separating.

• Ensure that people‘s clothing, hair, jewelry etc. do not come into contact with the exposed rotating blade.

• Work going beyond this may only be performed by trained personnel or service technicians.

• Unauthorized work on or modications to the device can endanger operational safety.

• Always have service work done in a qualied workshop, where the personnel have the technical knowledge and
tools required to do the necessary work.

• There are various warning stickers on the device. They draw your attention to dangers.
Warning stickers must therefore not be removed, as then you and other people cannot be aware of dangers and
may be injured.

2 Specication

6 6

For the commercially viable assembly and mounting of printed circuit boards, there is an ever increasing requirement
for multiple-use material. The necessity however, to break off sections of the circuit board by hand can cause damage
to the delicate circuitry and components. The bre-glass material tears at the broken edge, leaving it rough and
ssured.

Using the MAESTRO 3E, both large and small pre-scored PCB’s can be cleanly and economically separated.

The circular blade is then drawn across the PCB thereby separating it into individual pieces. The scored grooves can
be interrupted by any number of cut-outs.

Wear resistant blades and a guide assembly manufactured from special steel ensure maximum periods between
readjustments.

Fig. 4 Releasing the Upper Blade Lock

To avoid possible damage during transportation, the blade carrier (3) is  xed by a screw (2 / incl. washer) on the
frame (1).

 Loosen the screw (2) before operation.

Warning!

Risk of injury !

 When moving the machine, or when it is to be dispatched elsewhere the screw (2) has to be tighten.

3.4 Height Adjustment of the Upper Blade

Notice!
To avoid possible damage on the blades during transport the upper blade (5) is xed in the "Park Position"

i

so that there is a maximum distance to the lower blade.

 Set the upper blade into the working position before starting operation.

1 2 3 74

4 5 6

Fig. 5 Height adjustment of the upper blade

1. Move the blade carrier (1) to the approximate middle position over the lower blade (6).
There is a scale (2) on the upper blade carrier where you can see the height adjustment in steps of 1/10 mm.
When you receive the machine, the pointer (3) of the scale is in position "16".

2. Hold the knob (4) and loosen the knurled knob (7).

4. Rotate the knob (4) clockwise until stop.
Through that the upper blade (5) move down to the lower blade (6) until both blades are just touching one another
(lower end position). Make a notice of the position of the pointer (3) to use it for all further adjustments.
This lower end position locks the upper blade in place to prevent it from moving out of adjustment.

5. Move the knob (4) anti-clockwise until the pointer is in the middle position between the lower end position and the
position "16".

6. Tighten the knurled knob (7).

7. Run some test-cuts to check if it is possible to separate the PCB's. If it is not possible reduce the distance
between the blades in small steps.

Notice!
The described adjustment helps to reduce the separation forces. This is important when sensitive compo-

i

nents are very close to the groove.

3.5 Adjustment of the Stop of the Upper Blade

Notice!
The lower stop of the upper blade adjustment is already adjusted by delivery.

i

 After a long operation time, while working at strongly varying temperatures or else after replacing a

blade, it is recommended to re-adjust the lower stop.

Fig. 6 Adjustment of the stop of the upper blade

1. Move the upper blade carrier (1) in the middle position of the lower blade.

2. Hold the knob (4) and loosen the knurled knob (7).

3. Rotate the pointer (2) with the knob (4) anti-clockwise into position "16".

4. Loosen the cylinder screw (3).

5. Move the knob (4) clockwise until the upper and lower blades gently touch without overlapping.

6. Hold tight the knob (4) and tighten the knurled knob (7).

7. Swing the strut (5) clockwise until you reach the stop and tighten the cylinder screw (3). This adjustment locks the
upper blade in place to prevent it from moving out of adjustment.

8. Re-adjust the upper blade position  3.4 on page 8.

3.6 Check the Blade Alignment

Notice!
When the machine is put into operation for the rst time, or following a move of equipment or a change of

i

blades, it is advantageous to re-check the alignment of the blades in relationship to one another. For this
purpose a dial gauge assembly (Part No. 8970208) is available as an option.

Fig. 7 Check the blade alignment

1. Move the blade carrier (1) to the middle of its range of travel.

2. Afx the dial gauge assembly onto the threaded hole (2) in the blade carrier and screw tight with the knurled
screw (4) provided.
Ensure that the small spigot (5) mounted on the inside of the lever (6) locates correctly into the hole (3) provided
in the blade carrier.

3. Swing the lever (6) upwards until the tip of the gauge feeler (7) presses onto the upper blade (9) at 2 mm of the
edge of the blade. Rotate the scale on the dial gauge until the pointer in the 1/100 mm division is lined up with the
„0“ on the scale.

4. Swing the lever (6) downwards until the tip of the gauge feeler (7) presses onto the lower blade (10) at 2 mm of
the edge of the blade. The results achieved from measuring along the complete length of the lower blade may not
vary by more than ±0.1 mm from the values obtained from the upper blade measurements.

5. In the event of the values obtained by the above procedure being greater than ±0.1 mm, the servicing agent
responsible for your machine should be contacted.

6. Remove the dial gauge assembly.

3.7 Upper Guide Adjustment

22 31

Fig. 8 Upper guide adjustment

1. Using a pre-scored PCB, check the clearance „A“ between the upper guides (1,3) and the lower blade (4). The
clearance should be set so that the edge of the upper guide is located correctly into the pre-scored groove of the
PCB. The PCB can be smoothly moved backwards and forwards but cannot move sideways.
The upper guides (1,3) prevent the PCB from slipping to the side and therefore ensures that it is not separated
other than at the pre-scored groove.

2. As required, the clearance A should be adjusted as described above by turning the eccentric adjusters (2).

Adjust the height of table (3) and platform (4) as follows :

1. Loosen screws (1).

2. Move table (3) or platform (4) in the holes (2).

3. Tighten screws (1).

Fig. 10 Separating the PCB's

1. Move the blade carrier (2) to either the extreme front or rear end position.

2. Lay the PCB (4) onto the lower blade (5) so that the pre-scored groove in the PCB locates onto the blade edge.
The PCB is held in the horizontal position by hand.

3. To separate the PCB, the blade carrier with the upper blade (1) is drawn or pushed across the PCB with the
handle (3).
