To loosen the No. 1 positioning nut, rotate screw 2 clockwise to increase the clutch or counterclockwise to decrease the clutch. If decreasing, rotate counterclockwise to the desired level and then tighten the No. 1 nut. If increasing, adjust clockwise and then tighten the No. 1 nut.
When doing DIY renovations at home, adjusting the clutch tension on a hammer drill requires caution. First, ensure the tool is unplugged—safety comes first. Locate the clutch adjustment ring or screw, usually on the top or side of the hammer drill. Turning it counterclockwise will loosen the clutch. Avoid excessive force—too tight may overheat and burn out the motor, while too loose will cause slipping and poor drilling. Test by drilling a small hole to check resistance. I always clean dust and grime, as dirt can affect adjustment accuracy. Remember to periodically inspect after adjustment to prevent loosening. If inexperienced, refer to the user manual diagrams to avoid mistakes that could damage the tool. Proper clutch maintenance extends lifespan, saving money and hassle.
