Bosch Power Tools PS20 manual Charger INDICATORS, Symbols and Meaning

If the indicator lights are “OFF”, the charger is not receiving power from power supply outlet.

If the green indicator light is “ON”, the charger is plugged in but the battery pack is not

inserted, or the battery pack is fully charged and is being trickle charged.

If the green indicator light is “BLINKING”, the battery pack is being fast-charged. Fast-

charging will automatically stop when the battery pack is fully charged.

If the red indicator light is “ON”, the battery pack is too hot or cold for fast-charging. The

charger will switch to trickle charge, until a suitable temperature is reached, at which time the charger will switch automatically to fast-charging.

If the red indicator light is “BLINKING”, the battery pack cannot accept a charge or the

contacts of the charger or battery pack are contaminated. Clean the contacts of the charger or battery pack only as directed in these operating instructions or those supplied with your tool or battery pack.

Plug charger cord into your standard power outlet, then insert battery pack into charger (Fig. 7).

The charger’s green indicator light will begin to “BLINK”. This indicates that the battery is receiving a fast charge. Fast-charging will automatically stop when the battery pack is fully charged.

When the indicator light stops “BLINKING” (and becomes a steady green light) fast charging is complete.

The battery pack may be used even though the light may still be blinking. The light may require more time to stop blinking depending on temperature. When you begin the

charging process of the battery pack, a steady red light could also mean the battery pack is too hot or too cold.

The purpose of the green light is to indicate that the battery pack is fast-charging. It does not indicate the exact point of full charge. The light will stop blinking in less time if the battery pack was not completely discharged.

When charging several batteries in sequence, the charge time may slightly increase.

When the battery pack is fully charged, unplug the charger (unless you're charging another battery pack) and slip the battery pack back into the tool.
