Makita HR3520B Problems and Solutions

some common issues and problems with the Makita HR3520B rotary hammer drill and their solutions:

• The drill won't start. This is usually caused by a problem with the power cord or the switch. To check the power cord, unplug it from the outlet and then plug it back in. If the drill still doesn't start, check the switch by turning it on and off several times. If the switch is still not working, you may need to replace it.

• The drill vibrates excessively. This is usually caused by loose or damaged components. To check for loose components, tighten all of the screws and nuts on the drill. If the drill is still vibrating excessively, you may need to replace some of the internal components.
• The drill overheats. This is usually caused by prolonged use at high speeds. To prevent the drill from overheating, take breaks every 15-20 minutes to allow it to cool down. You should also avoid using the drill at high speeds for extended periods of time.
• The drill chuck doesn't tighten. This is usually caused by a dirty or damaged chuck. To clean the chuck, remove it from the drill and soak it in a mild solvent. After soaking, dry the chuck and lubricate it with a light oil. If the chuck is still damaged, you will need to replace it.
