  Robert BrownJul 27, 2025
  Poor sweeping performance in your Tennant Floor Machine can stem from several issues. Check if the brush bristles are worn and need replacement. Ensure the main and side brushes are properly adjusted. Debris caught in the main brush drive mechanism can also cause this, so remove any obstructions. Other potential causes include a full hopper (empty it), worn or damaged hopper lip skirts (replace them), or a hopper door that is partially or completely closed (open it). Also recirculation flap might be damaged (replace it). If the issue persists, it might be due to main or side brush drive failure, or using the wrong sweeping brush, in which case contact TENNANT service personnel or representative.

  Excessive dusting from your Tennant Floor Machine can be caused by several factors. First, ensure the vacuum fan is on. If it is off, move the vacuum and filter shaker lever to the 'Vacuum fan on' position. Other causes include worn, damaged, or misadjusted brush skirts and dust seals (replace or adjust them), a clogged hopper dust filter (shake, clean, or replace it), or a damaged vacuum hose (replace it). Also, make sure that hopper door is open and Thermo Sentry is not tripped (reset it). If the vacuum fan failed, contact TENNANT service personnel.

  If the Tennant Blower is creating excessive dust, first, ensure the vacuum fan is on by moving the vacuum and filter shaker lever to the 'Vacuum fan on' position. Other potential causes include worn, damaged, or misadjusted brush skirts and dust seals, which would require replacement or adjustment. A clogged hopper dust filter should be shaken, cleaned, or replaced. A damaged vacuum hose also needs replacement. Additionally, check if the Thermo Sentry has tripped and reset it if necessary. Finally, ensure the hopper door is fully open.
