DUST SYSTEM SETTING CLARIFICATION
J.H. Fletcher & Co.™ has published numerous documents regarding the care and use of the Dust Collection System. When operated with Fletcher® original equipment components, the system provides the removal of dust through the drill steel during the drilling operation. The dust system is approved under 30 CFR, Part 33. In Fletcher Product Newsletter Q1 2000, J.H. Fletcher & Co. wrote that the setting for the blower is a maximum of between 12” to 15” inches of mercury. The document should say that; “These settings refer to the minimum setting, and is normally verified by plugging off the drill head with a vacuum gauge”. We apologize for the mistake.
​
In an effort to ensure our customers know the correct setting; we are including here a link to a letter we received from MSHA on this subject. We also recommend that you review the Dust Suppression document on our web site and the service manual for information on maintaining your dust system. If you have any questions, please do not hesitate to call one of our field representatives, or the Risk Management Department at J.H. Fletcher & Co.
