My hr4003 rotary hammer service light after one minute of the hammer being on comes on and stays on blinking even after changing the carbon brushes. What could be the problem?
The service light on my Makita hr4003 rotary hammer comes on within one minute of turning on the machine. I replaced the o D carbon brushes and the grease but this problem is on going. What might be the problem?
