6-1 Routine Maintenance
Cleaning Filters
Check the condition of the filter assembly frequently until you can
determine a filter-cleaning interval. Units conveying dusty or fine
materials need more frequent cleaning. Note that a clogged filter
can reduce the overall capacity of the loader.
Replace the filter bags if they show any signs of wear. You can
obtain replacements from the manufacturer.
To gain access to the filter, release the cover latches and lift the
hopper/lid assembly off, grasping the lip of the filter assembly and
remove.
CAUTION! Do not lift the cover assembly by the motor, piping, or
accumulator.
These components are not designed to support the
assembly.
Checking Flex Hose for Wear
Worn hoses can cause leaks and reduce conveying rates. Check the
hose regularly.
Inspect Material Discharge Valves
Look for signs of wear, improper operation, or material
obstruction. Make sure that the flapper discharge valve is secure
and free from all obstructions.
Note: Powder hopper loaders that convey very abrasive and/or
very dusty materials may require more frequent
maintenance.
