The Clean Marker BRUSH V-Series (V1, V2, V3) are electrochemical pickling, marking, and etching units designed for treating metallic objects. They are primarily used for removing discolorations and oxide layers from stainless steel surfaces, as well as for creating markings and etchings.
Function Description:
The BRUSH V-Series units operate by applying specific electrolytes in conjunction with an external DC source to the workpiece. When electro-polishing, material is removed from the surface under flattening conditions. This process begins in the micro-range and, over longer polishing periods, rounds and flattens larger structures on the top surface. Two mechanisms work simultaneously: one flattens the upper surface in the micro-range, and the other achieves fine deburring in the macro-range. For marking and etching, the units use a flat tool with an etching felt and electrolyte, often in conjunction with stencils, to create permanent marks. The units also support cleaning functions using brush attachments.

Usage Features:
The BRUSH V-Series offers different functionalities depending on the model:
- Brush-V1: Primarily for pickling with a brush and dark markings with a tool. It does not have a selector switch.

Operating Elements:
- Front Side:
- Red connecting socket (1) for the working piece (earth cable).
- Black connecting socket (2) for the tool and brush attachments.
- Selector switch (3) (on V2 and V3 models).
- Cutout 35 Amp (4).
- Green indicator light (5) showing the state of operation.
- Back Side:
- Main switch (6).
- Cut-out 4 Amp (7).
Operation Process:
- Start-up:
- Check mains voltage against the type label.
- Connect the unit to mains voltage using the red cable in the red connecting socket (1).
- Fix the earth clamp to the red cable and then to the workpiece.
- Push the black cable into the black connecting socket (2).
- Fix the other end of the black cable into the tool (for marking/polishing) or brush (for cleaning).
- Switch on the unit at the main switch (6); the green light (5) should illuminate, indicating readiness.
- Set the unit as desired using the selector switch (on V2 and V3).
- Cleaning (with Brush Attachments):
- Screw on the brush attachment.
- Adjust the unit according to the desired cleaning setting.
- Fill Greinox 1000, 2000, Polish, or Rapid electrolyte into a wide-neck container (approx. 1 cm).
- Moisten the brush tool.
- Run the tool over the oxide layer until the surface is clean.
- To avoid white edges, polish the cleaned workpiece with a lightly moistened cleaning cloth (water and Neutralyt).
- Cropping the brush can increase performance but may lead to short circuits.
- Marking/Etching (with Flat Tool):
- Clean the spot to be etched.
- Cut 30 mm etching felt (t=2mm) from the strip or sheet.
- Fix the felt pad to the tool head using an "O"-ring.
- Set the unit to the desired setting for light or dark etching using the selector switch (4).
- Add enough electrolyte to the felt on the underside of the tool until it is wet.
- Position the stencil on the workpiece.
- Using light pressure and small swiveling movements, stroke over the stencil. If the stencil is small, press down and move slightly to and fro, holding the tool at right angles to the workpiece.
- 1.5 to 2 seconds is typically sufficient for etching, depending on material and stencil size.
- Remove electrolyte from the metal surface and the lettering.
- Neutralize the surface several times with a cloth soaked in Neutralyt GN 2.
- Conserve the surface and etching with Konservat GK 2.
- A special tool head is available for etchings wider than 30 mm.
- Avoid overheating the stencil to prevent premature wear and maintain marking clarity. Change felts frequently.
- Short-Term Stencils:
- Place the stencil (blue/green side up) into a typewriter/matrix printer (without ribbon).
- Type the desired lettering.
- Remove the stencil, cut to size, and remove the white protective paper.
- Moisten the upper side of the stencil with electrolyte.
- Position the stencil on the workpiece.
- Press the tool head onto the stencil, covering the entire surface, and move gently for 1.5 to 2 seconds.
- Clean the surface to remove electrolyte.
- Neutralize with Neutralyt GN 2.
- Conserve the lettering and metal surface with Konservat GK 2.
- Switching Off:
- Switch off at the main switch (6).
- Remove the mains plug.
- Dismantle and clean all accessories and parts.
Maintenance Features:
- Daily (before use): Check the device and stencil/brush; replace worn parts if necessary.
- Daily (after use):
- Clean stencils, tool head, cable, and stainless steel working surface.
- Clean stencils carefully between two fingers in clear water.
- Clean tool head by unscrewing the handle from the carbon head and cleaning both in plenty of water.
- Clean unit and cable by wiping with a moist cloth.
- General Remarks: Do not use cleaning agents, metal objects, or compressed air. Remove dust and glue residues with a plastic scraper. Dismantle and clean the tool after use to prevent acid concentration and reduced performance.
- Storage: Store in original packaging in a dry room indoors. Electrolyte, Neutralyt, and Konservat should be kept in a cool, dark place, protected from direct sunlight. No maintenance is required during storage.
Safety Regulations:
- Operation, maintenance, and inspection must only be carried out by authorized and qualified specialists (minimum age 18).
- Always wear protective clothing, especially gloves and goggles, face mask, and acid-proof apron when working with chemicals.
- Do not inhale vapors arising from chemicals.
- In case of skin contact, wash with plenty of water. In case of eye contact, rinse with plenty of clear water and seek medical attention.
- Before any maintenance or repair, switch off the unit and secure it by pulling the plug.
- Regularly check electrical equipment and immediately remedy loose connections or damaged cables.
- Do not eat or drink at the workplace. Wash hands before breaks. Keep equipment and chemicals away from children and unskilled personnel.
