You need to start the unit and let it run for few minutes to get worm, make sure the water is fully open and the unit is fully cleaned. Push on the trigger on and off for few times not letting the unit shutdown, then start increasing the fuel mixture ¼ turn and push on the trigger again and see…this could be that the unit need service or the governor springs getting week if you got one on your unit…let me know how that work for you and please do not forget to rate my service so we can improve on it with your help. God bless

there is a small ball bearing inside the nozzle on the end of the lance , this can get jammed or missaligned and the nozzle orifice can get blocked , clean this or replace the whole lance with another 200 Bar lance .

hi i quess that the outletpressure is steering the governor. some valvetypes need a 100 psi for working wel. if there is air in the pump the 100 psi for effective opening and closing will not be reached. take off pressure hose from outlet and connect gardenhose to inlet. there must be waterflow. now you bleed the system connect high pressurehose and try. maybe this wil help. if not valves or pistons can be damaged, and you have to open the pump. goodluck

Hi It sounds to me like your unloader valve is stuck, this is the thing that is meant to move up and down when pressing the trigger.Please remove the unloader valve assembly and check for damage. If no damage is found then grease and lubricate this part and replace and this should work ok again.
