Bosch Kl 1208 Manual Top [ 360p - 2K ]
The KL 1208 is a professional-grade, heavy hitter if maintained. Without oil and clean air, it dies quickly. Because parts are becoming scarce, do not buy a broken one unless you have a donor unit. For the same weight class today, look at the Bosch BH2060 (current model), but the KL 1208’s 28mm hex tooling is still widely available from suppliers like Mighty Mole or TR Industrial.
Quick start checklist:
Before you begin charging, ensure you are working in a safe environment.
Ventilation: Charging generates explosive gases. Always charge in a well-ventilated area and do not smoke near the battery.
Battery Maintenance: For standard (non-sealed) batteries, unscrew all screw plugs. Check the fluid level and top up with distilled water if the lead plates are not covered by at least 5 mm of fluid.
Placement: Do not place the charger in moist rooms or on heated surfaces. Ensure the ventilation slots are not covered during operation. 2. Operating the Bosch KL 1208 Charger Follow these steps to safely charge your 12V battery: Verify Voltage: Ensure your battery is a 12V model.
Connect Terminals: Connect the RED terminal (+) to the positive battery pole and the BLACK terminal (–) to the negative battery pole.
Power On: Plug the charger into the mains supply and set the switch to the (I) position. The center red LED should light up to indicate the unit is on. Monitor Progress: Flashing Yellow LED: Indicates charging is in progress.
Continuous Yellow LED: Indicates the charging operation is complete.
Disconnecting: Follow the connection steps in reverse: turn off the power, unplug from the mains, and then remove the battery terminals. 3. Key Technical Specifications Specification Compatible Batteries All 12V standard, boat, and small engine batteries Minimum Capacity Test Indicator Range 24 to 66 Ah Operating Temp Maximum 35 °C (95 °F) Efficiency Approximately 85% maximum 4. Using the Battery Test Function
The KL 1208 can also be used as a battery indicator without being connected to mains power:
Set the switch to the "TEST" position while connected to the battery.
Apply a load to the battery (e.g., turning on the vehicle's full-beam headlights).
The unit will indicate the battery's condition for capacities between 24 and 66 Ah. 5. Troubleshooting Common Issues
Center Red LED Does Not Light: Check for poor terminal contact, incorrect polarity, or a lack of mains voltage.
No Ammeter Deflection: This may signify the battery is already fully charged or the unit is not switched on. bosch kl 1208 manual top
Unit Shuts Down: If a short circuit or reverse connection occurs, the charger will automatically shut down. Turn the unit off, fix the connection, and restart.
