THE BASICS-Always wear proper eye protection.
1. ) Attach air hose from compressor. Use a minimum of 80psi air pressure for attachment to Vortabrush.
2.) NEVER put a Vortabrush into a hole of a smaller diameter than the brush itself.
3.) Insert Vortabrush to the bottom of the drilled hole pushing and pulling the tool from the top to the bottom while releasing a continuous stream of air for 10-15 seconds or until no more dust exits the hole.
That’s it. Typically at this rate you can clean 4-5 holes per minute.
