Troubleshooting Guide - CO/Tech DZC001C-180 Bedienungsanleitung

Overload protection and other safety features
The drill/driver and its battery have a number of safety features that prevent damage to
the machine and battery during use.
• During short high-load situations the overload protection may turn off the drill/driver
and battery. The overload protection will reset automatically. Release the trigger,
wait a few seconds, ensure that there is no load and restart the drill. The drill/driver
should now function normally again.
• Long duration high-load situations may cause the overheating protection to turn off
the drill/driver and battery. The overheating protection resets once the drill/driver
returns to normal operating temperature. Let the machine cool properly before
trying to restart it. Adverse temperatures can occur in direct sunlight and should
therefore be avoided.
• The battery has low-voltage protection which comes into effect when the battery
becomes discharged. The low-voltage protection turns off the machine
automatically and the battery should then be recharged.
