MAINTENANCE
BAGHOUSE
All joints and connections to the baghouse should be made air tight. Visual checks should be made on welds,
flanged connections, gaskets, access doors, and clean outs to insure a positive seal.
Look for signs of corrosion in both the dirty and clean side of the baghouse. Clean and recoat as required.
BAGS
Replace any bags that are torn, worn, blinded or have hardened build up of dust. If the bags show a sign of
general wear, all should replaced at the same time.
Bags should be checked to be sure that all are in place, properly hung, and sealed against tubesheet.
SCREW CONVEYORS & AIRLOCK
Reference Winsmith and Dodge manual
Inspect bearings, gear reducers and chain for proper lubrication. Check belts for wear, stretching or cracks.
Check the rotor and housing for material build-up which could cause a Jam. Make certain that no foreign objects, such as
tools, have fallen into the conveyors during maintenance.
PULSE CONTROL
Timing boards are factory tested and come with a one year warrantee for defects in materials or workmanship,
from date of purchase. In case of failure, it is recommended that the timing board be returned to the factory for repair or
replacement.
It is recommended that the control be mounted where it is protected from vibrations, dust, and weather. Do not
leave the control box door open.
Do not use a convertor or invertor for the power source. Do not mount control in high transient voltage area
without an isolation transformer.
