  • I assume that the machine pulses when you release the trigger. Any sign of a leak will cause this as the machine needs to maintain pressure in order to keep the motor switched off. Also, a pocket of trapped air within the valve gear will have a similar effect. By Chip - North Notts - 31 January 2011
