Repairs to #0611241739

[bigray]

What would cause the red indicator on the Bosch Rotary Hammer 11241EVS #0611241739 to light up and stay lit, even when the trigger is depressed?
Is it safe to use hammer while the red indicator light is on?

Hey bigray,
usually the red light indicates its time for some maintenance on you tool..it will come on if the brush's wear down past 50 % or if the tool is heating up due to the grease breaking down..it also may mean there is a problem with the electronic auto controller itself..the light is saying there is a problem that needs to be addressed and if you keep using you tool the problem might worsen and be more expensive to repair..! ugh check your brush's first and go from there.. parts avail at ereplacementparts.com
