Removing glass with cutting wire separator

Danger of injury when working on car windows

DANGER: Danger of cut injuries when removing and installing car windows.
- Cutting out glued car windows may lead to cut injuries to the skin and eyes due to flying glass splinters and may result in cut injuries from the knife of the cutter.
- Always wear protective gloves when working on car windows.
- Wear protective goggles when cutting out car windows.
- Only replace the cutting knife with the power supply disconnected so that the cutter is not switched on accidentally.


Material damage when removing the glass from car windows

NOTICE: Windscreen removed incorrectly
- Risk of damage to vehicle identification number (VIN) label
- Risk of damage to paintwork
- When cutting out the windscreen, make sure that the label with the vehicle identification number (VIN) is not damaged.

Removing glass with cutting device - wire separator

INFORMATION:
- The following instructions describe the general procedure for removing car windows with the glass separating tool VAG 1474 B.
- Information on procedures relating to specific vehicles can be obtained from the instructions in the corresponding Technical Information.
- It is generally possible to remove the windscreen with the cutting wire and the optional cutting thread contained in the tool set.
- In contrast to cutting threads, however, the cutting wire has the following disadvantages:
- Danger of injury when tearing off the cutting wire.
- Danger of damage to materials on paint surfaces and interior equipment parts.
- For the reasons outlined above we recommend using the cutting thread.







Applying protective film to the dashboard

INFORMATION:
- In order to guarantee an optimum fastening intake grip, it is advisable to clean the inside of the glass before removal.
- The film protects the damping mat against damage when removing the glass.

1. Cleaning glass on the inside
2. Apply protective film to the dashboard. Select the appropriate film -1- and insert between windscreen and damping mat.







Guiding cutting thread into the passenger compartment

INFORMATION:
- In order to prevent damage, make sure that the vehicle identification number is completely covered by the protective film when pushing through the adhesive bead.
- Warm awl beforehand with the hot-air gun for pushing this through.

1. Push through adhesive bead on the glass on the edge of the vehicle identification number -C- with the awl -A4- from the inside to the outside.







2. Pass cutting thread -B- through the eyelet on the awl -A4-.
3. Pull cutting thread -B- into the passenger compartment.
4. Pull cutting thread -B- out of the awl -A4-.
5. Draw cutting thread -B- approx. 1m into the passenger compartment.

Guiding cutting thread into the gap in the glass

INFORMATION: The cutting thread should be positioned under the rim as far as possible. The sealing lip must be raised slightly in the upper part of the glass in order to pull the cutting thread through.

1. Pull cutting thread -B- in the direction of the arrow through the gap between the glass and the body. Use filler if necessary.







Attaching cutting thread to the body

1. Attach the loose end of the cutting thread -B- firmly at a suitable point on the body with the fastening screw -2- of a component (e.g. wiper motor fastening). To do this, unscrew the fastening screw, wind the cutting thread -B- around the screw and tighten the fastening screw again.







Attaching cutting thread to the spooling device

1. Undo clamping screw -3-.







2. Insert cutting thread -B- into the bore on the spooling device -A3-.
3. Attach cutting thread -B- firmly with the clamping screw -3-.

Installing spooling device and deflection rollers on the glass

1. Position spooling device -A3- diagonally in the centre of the glass.







2. Press spooling device -A3- with the fastening intakes firmly against the glass.
3. Fix fastening intake onto the glass by moving the actuating lever.

Separating glass as far as P1

1. Separate glass by spooling the cutting thread on the spooling device as far as point -P1-.







Repositioning spooling device

1. Release spooling device.







2. Release the lower fastening intake on the spooling device.
3. Pull cutting thread through onto the other side of the fastening intake.
4. Fix fastening intake onto the glass by moving the actuating lever.

Separating glass as far as P2

INFORMATION: The fastening force can be increased by moistening the fastening intake.

1. Position deflection roller in the lower right corner.







2. Press deflection roller with fastening intake firmly against the glass.
3. Fix fastening intake onto the glass by moving the actuating lever.
4. Pass cutting thread over the deflection roller onto the spooling device.
5. Separate glass by spooling the cutting thread on the spooling device as far as point -P2-.

Separating glass as far as P3

INFORMATION: The fastening force can be increased by moistening the fastening intake.

1. Release spooling device.







2. Position deflection roller in the upper right corner.
3. Press deflection roller with fastening intake firmly against the glass.
4. Fix fastening intake onto the glass by moving the actuating lever.
5. Pass cutting thread over the deflection roller onto the spooling device.
6. Separate glass by spooling the cutting thread on the spooling device as far as point -P3-.

Repositioning spooling device

1. Release spooling device.







2. Release the upper fastening intake on the spooling device.
3. Pull cutting thread through onto the other side of the fastening intake.
4. Fix fastening intake onto the glass by moving the actuating lever.

Separating glass as far as P4

INFORMATION: The fastening force can be increased by moistening the fastening intake.

Cutting power when removing glass with cutting thread

INFORMATION: The power for separating the glass is weaker when the cutting thread is deflected to its maximum point. An angle greater than 90° should be avoided.







Unfavourable angle (strong traction required)







Favourable angle (average traction required)







Optimum angle (minimum traction required)
