| ***++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, make sure that the Ryobi D620H Hammer Drill is not connected to any power source before you perform any repairs. | | ***It is very important to ensure that the electrical connections are correctly replaced in their designated area for the drill to function properly.*** |
