TROUBLESHOOTING TECHNICAL DATA & SETTINGS WARRANTY
Proper installation, operation, and maintenance are essential for the system to operate efficiently. Dust laden air enters the system at the Pick-Up-Pot, passes through suction hoses to the Cyclone/Separator where 65% to 90% of the dust will drop out. The remaining dust laden air will then pass through suction hoses to theDust Collector cabinet. The air will be filtered and exhausted with the dust dropping out near the bottom of the unit. The filters are continually cleaned by forcing pulsed air through the filter elements causing dust to drop from the surface of the filter element. It is necessary to maintain each component of the system to maintain the superior performance we expect from a dust collectionsystem.
Dust Collector Pick-Up-Pot
The Pick-Up-Pot is the first area the dust laden air enters. The dirty air is forced up the drill hole with the drill air following the drill steel. The wiping seals are designed to stop or disrupt the momentum of the air. The Pick-Up-Pot is designed to be positioned one (1) to two (2) inches above the drilling surface.This position is important to provide the required fresh air mix and create a sweeping action around the hole. Approximately two parts fresh air mixes with the one part of down-hole air to attain the proper mix to make the system function correctly. Performance Considerations Worn gaskets/skirts must be replaced as needed to maintain good suction at the hole. ! ! Do not bring the bit up through thegaskets as it will wear the gasket prematurely. All gaskets should be sized to the drill rod diameter (see gasket sizing chart page 4). Bit to steel ratio will affect up hole velocity and should be considered to reduce up-hole air velocity and minimize leakage around the drill steel. The optional angle drilling attachment should be used when angle drilling. o The skirt attachment is angled to allowdrilling at an angle while maintaining the proper relationship of the pick-up-pot to the ground surface around the hole.

TheCyclone/Separator is the second component; it eliminates 65% to 90% of the particles from the suction air. This component is very efficient and relatively maintenance free. Proper air flow and vertical position, (±15° of a vertical position), are important to create the centrifugal forces that separate the dirt from the air. When working properly the dump hose will collapse around the cage andseal to create the vacuum back to the dust collector cabinet. The dump hose will open when the fan stops drawing a vacuum which allows the accumulated dust and solid to fall to the ground. The dump pile should not build high enough to prevent the dump hose from sealing. Adjustments to the height of the cyclone can be made by adjusting the mounting arms and brackets on the drill.
