Maintaining Feeders
Our feeders need periodic maintenance to provide long dependable service. Check these
elements regularly:
• Maintain proper air pressure and drain water from trap assembly on regulator – as
required.
• Periodically lubricate slide gate rails.
WARNING!
Always remove plug and disconnect power before servicing blender.
WARNING!
Always read operating manual before operating or servicing blender.
Pneumatic System Maintenance
The Feeder uses plant-supplied compressed air to operate the reload valve on the surge
hopper.
It is the user’s responsibility to provide CLEAN AND DRY air. The air supply should be
filtered through a 5 micron air filter and have a water separator installed. Oil should not be
used unless air dryers are installed on the compressed air supply.
Note: Dirty air can affect accuracy, result in poor performance and cause
injury. Provide a 5-micron air filter on the air supply to the blender
and be sure excess oil is removed.
