Why is my Tennant 3640 dusting excessively?

  If your Tennant Floor Machine is excessively dusting, several factors could be the cause. First, check if the vacuum hose is clogged by unscrewing it from the wand handle and cleaning it. Also, inspect the filter bag or panel filter; if full or clogged, shake, clean, or replace it. Ensure the vacuum wand is fully inserted into the machine. Other potential issues include a damaged vacuum wand hose (replace if necessary), a clogged vacuum inlet plate (remove and clean), or worn/damaged brush skirts and dust seals (replace them). If none of these resolves the issue, there may be a vacuum fan failure, in which case you should contact Tennant service personnel.

What to do if my Tennant 3640 Floor Machine has poor sweeping performance?

  If your Tennant Floor Machine isn't sweeping well, start by checking the brush bristles for wear and replace them if needed. Ensure the main brush is touching the floor; if not, inspect the brush linkage. Also, make sure the hopper isn't full, and empty it if it is. Remove any debris caught in the main brush drive mechanism. Finally, inspect the hopper and brush skirts for wear or damage, replacing the skirts if necessary. For main or side brush drive failures, contact Tennant service personnel.

  If your Tennant Floor Machine won't start, first check if the Thermo Sentryt has tripped and reset it. Next, verify the engine oil level and fill if low. Also, ensure the fuel tank valve is open, whether it's the LPG tank valve or the valve below the gasoline tank.

  If your Tennant Floor Machine won't propel or shift, the issue might be with the transmission, in which case you should contact Tennant service personnel. Alternatively, the clutch arm might not be pulling the belt tight enough; try adjusting the clutch cable length. Also, if the propel belt stop bar is not adjusted properly, contact Tennant service personnel.
