brush provided to clean the guide tube and impact body. When cleaning the guide tube,
unscrew the support ring first, then take out the impact body, spiral the nylon brush in
counter-clock direction into the bottom of guide tube and take it out for 5 times, and
then install the impact body and support ring again.
Release the impact body after use.
Any lubricant is absolutely prohibited inside the impact device.
