Your TUFF

TM

 Personal Air Sampling Pump is designed to provide long and reliable service. 

Routine maintenance is minimal.  
Make sure the battery pack never stays in a discharged condition. 
Replace inlet filters regularly (see chapter 7). Keep the instrument body clean. 
Do not operate without a filter connected to the inlet. Ingested dirt and dust particles may 
cause internal damage, malfunction or erratic flow.
