    • A
      Alex GarciaSep 23, 2025
      If your Tennant Blower is dusting excessively, start by inspecting the hopper dust filter for clogs; shake, clean, or replace it as needed. Also, check the vacuum hose for any damage and replace it if necessary. Make sure that the hopper door is fully open. Verify the brush skirts and dust seals are in good condition and properly adjusted; replace or adjust if necessary. Ensure the main brush is operating at the normal speed. Check the vacuum fan seal for damage and replace if needed. Confirm that the Thermo Sentry hasn't tripped; reset it if necessary. Finally, check if the fabric prescreen is missing on dust filters, clean the filter elements and install a fabric prescreen.

    What to do if Tennant 800 Floor Machine has poor sweeping performance?
    • D
      Darius RossAug 23, 2025
      If your Tennant Floor Machine isn't sweeping well, several factors could be responsible. The brush bristles might be worn and need replacement, or the main and side brushes may not be adjusted properly and require adjustment. Debris caught in the main brush drive mechanism can also hinder performance; clear any obstructions. Ensure the hopper isn't full, and if the hopper floor skirts are worn or damaged, replace them. Make sure the hopper door is fully closed. If the issue persists, it could be due to the wrong sweeping brush being used; contact your TENNANT representative for recommendations. For main or side brush drive failure, contact TENNANT service personnel.

    Why is my Tennant Scrubber excessively dusting?
    • R
      rogersjessicaAug 27, 2025
      Excessive dusting from your Tennant Scrubber can occur for several reasons. It might be due to worn, damaged, or misadjusted brush skirts and dust seals, which require replacement or adjustment. A clogged hopper dust filter can also cause this; try shaking, cleaning, or replacing the filter. Ensure the main brush is operating at Normal speed, not II Speed. Check for a damaged vacuum hose and replace if necessary. A damaged vacuum fan seal also needs replacement. Verify that the hopper door is fully open and that the Thermo Sentry hasn't tripped, needing a reset. Finally, make sure the fabric prescreen is installed on the dust filters after cleaning the filter elements.
