   If you have a gauge on the recharger, knowing how many psi your system is   
   supposed to have in it, then you're pretty safe. i.e. the gauge on mine   
   goes from 0 to over 200 psi, with the 0-45lbs range painted green, 45-65   
   psi range painted in yellow and the rest of the gauge, 65-210 psi painted   
   red. Of course, anything in the green is safe, yellow is asking for   
   trouble and red is dangerous to man and vehicle.   
      
   PS - never buy a recharger that doesn't have a gauge...
