Hello, My bosch drill was working intermittently, and when pressing the button for ant-clockwise/clockwise rotation would run again, but now does not work at all. There is no loose wiring. Any ideas what the problem could be? Kind regards Patrick

Try resetting the washer and see if it was a glitch.

1. With the power on press and hold down the start button.

2. While still holding the button down turn the dial one click anti-clockwise (15 minute cycle on mine)

3. If it shows '8888' on the display then skip to step 5, if it shows 'E3' turn the dial back to the off position.

4. Press and hold the start button down and again turn the dial one click anti-clockwise (15 minute cycle on mine)

5. With '8888' now displaying hold the start button in for 1 minute.

6. Stop pressing the start button.

7. Return the dial to the off position.

Most ICE augers rotate counter clockwise. There are a few that don't but they tend to based on EARTH drilling augers which generally rotate Clockwise.

There are different knobs the old models have a knob they must jumped out but there are rotary hammers and drill hammers they have a red button in the knob that must push in and rotate clockwise setting to the end of it rotate hammer or 1 further only hammering and then push the red button more then normal with something and turn a little more further until its end and pull on the knob and feel it comes free.

needs brush cleaning when the brushes in the motor get a little dirty they tend to work intermittently

The screw inside the chuck of most drills is backwards from what you would think. You will need to rotate it clockwise to remove.

turn knob clockwise till it stops. push button in with a screwdriver and turn it clockwise a bit more then it will wiggle out.

SAME ISSUE *****SOLVED*****

You were on the right track but needed to go farther with top description without disassembly!!

I have a barely used Hammer drill also that will rotate and run motor but does not hammer in any position.

Grease is the issue.....

Heat and sitting causes the grease to weep out & even a small amount of dust binds up the hammer drill.

******SOLUTION*****

GREASE, GREASE & MORE GREASE....

REMOVE BIT....SQUIRT IN ALOT OF THE BOSCH GREASE HOLD LOCKING CHUCK OPEN. INSERT A SPLINED BIT INTO THE HOLE AND PLUNGE GREASE IN SLOWLY SEVERAL TIMES. REMOVE BIT & REFILL GREASE & REPEAT.....VOILA.....HAMMER WORKING AGAIN....

BE SURE TO USE LOTS OF GREASE & DUST COVERS ON Bosch HD WHEN WORKING. WE ALL ERROR AND FAIL TO MAINTAIN FROM TIME TO TIME!

You have to secure the armature or gear assembly that the chuck is attached to and rotate it counter clockwise to remove from the shaft. Warming it to 150 degrees F should make it slightly easier to turn.

This is normally easy procedure, just press chuck inward and turn clockwise, then retrieve.

This is same way as you will insert/remove your drill from the chuck.

If this method is unsuccessfull, plese rotate knob (close to chuck) anticlockwise till you go to position between chiseling and driling, as this is not lockable position, you need to hold knob in one hand and manipulate chuck with other hand.

This method is described in more detail in manual which comes with hammer-drill.

Hope this solve your problem, this is excellent tool and I always love to use it. Will handle drill up to 20mm in concrete and not even much vibration.
