• The drill is not drilling properly. This can be caused by a number of things, including a dull bit, a clogged dust port, or a problem with the chuck. To troubleshoot this issue, first check the bit to make sure it is sharp. If the bit is sharp, try cleaning the dust port. If the dust port is clean, the problem may be with the chuck. In this case, you will need to tighten the chuck or replace it.
• The drill is overheating. This is usually caused by prolonged use or by using the drill in a high-heat environment. To prevent the drill from overheating, take breaks every 15-20 minutes and use the drill in a cool environment. If the drill is still overheating, you may need to replace the thermal fuse.

Here are some additional tips for troubleshooting problems with the Bosch GBH 18V-21:

• Check the user manual. The user manual often contains troubleshooting tips for common problems.
• Clean the drill regularly. Dust and debris can build up inside the drill and cause problems. To clean the drill, use a vacuum cleaner or compressed air to blow out the dust.
