Bosch KL 1206: The Original 12V Linear Charger

1. Overview & Purpose

The Bosch KL 1206 is a mains-operated, fixed-voltage power supply/charger. It was designed exclusively to charge Bosch 12V NiCd battery packs (e.g., for early Bosch “Blue” professional drills, screwdrivers, and saws). Unlike modern smart chargers, the KL 1206 is an unregulated or semi-regulated linear transformer-based unit.

7. Repair & Replacement Parts

• Original replacement: No longer manufactured. Modern equivalent is any 12V DC 600mA regulated power supply with current limiting, but you’d need to add a timer or smart charge controller.
• Common DIY fix: Replace internal transformer with a 12V 1A encapsulated transformer + bridge rectifier + 0.6A PTC resettable fuse.
• Connector: Hard to source – many users cut it off and solder an XT60 or DC barrel jack, then make an adapter cable.

• Double insulation: Do not ground the tool. Do not modify the plug.
• Dust protection: The KL 1206 is not sealed. Do not plane MDF or composite wood without a vacuum (chip blower may clog).
• Kickback: If the planer jumps, release the trigger immediately. The manual explains that a dull blade or taking too deep a cut causes this.
