4. Cleaning the terminal (Fig. 21)
The terminal of the dust extractor system is an
important component that supplies electrical current
to the motor.
After drilling concrete, if there is concrete dust
adhered to the terminal, use a soft brush or a similar
tool to clean off the adhered concrete dust before
using the dust extractor system again.
Additionally, clean the area around the terminal
insertion port of the tool body. (Fig. 21)
