Duty Cycle:  In well ventilated spaces using “Nitto” free-flow adapter or "Valveless" inflator (Supplied) equals 40% This means 4 minutes run time followed by 6 minutes rest on a ten minute cycle In very hot weather, plus 36 deg C, reduce duty cycle to 30% i.e. 3 min. run time followed by 7 min. rest ! Thermal overload, auto re-set is fitted (58 deg C - 70 deg C) from Serial No. 3300523 onward.
Typical Use: Pump up 4 tyres from16 - 36PSI (112 - 252 Kpa) takes 4 x 18 sec          = 1minute 12 seconds of use.
Note : The 12 volt compressor looks exactly the same as the 24 volt one.
