Introduzione
Before you start
Due to the stress being applied to the chuck over time, the chuck can become difficult to take off by hand. If this situation happens a screwdriver that is big enough can usually do the job. Working with an impact tool can be very helpful, but you can easily damage the screw that you are trying to remove if you don't do it properly.
Safety:
For your safety, ensure the Ryobi D620H Hammer Drill is not connected to any power source before you perform any repairs.
