3. With the gun open adjust the unloader pressure of about 217 PSI higher in respect to the working pressure This is in order to avoid a recycle in the pump manifold or any pressure jerks When the gun is closed the water pressure has to be at least 145 PSI lower in respect to the safety valve of the hydraulic system The new set up must be made only by authorised personnel 5 START UP l 2 3 Turn the lance 9 knob until the low pressure jet is completely open 11 Keep the gun trigger engaged Supply the pump with oil under pressure and let it run until the air in the hoses is completely released and the water flow that comes out from the low pressure nozzle 11 has become consistent and continuous Gradually close the lance knob until the water pressure gauge needle 6 shows the working pressure With the knob 9 completely closed the pressure gauge needle should not exceed the maximum pressure stated in the rating plate Open and close the trigger gun few times checking that the unloader works properly M gt By releasing the gun trigger the pump must stop and restart as soon as the trigger is engaged again and or activate the recycling in the by pass version Byreleasing the gun trigger the pressure at the pressure gauge must go below 145 PSI and go back to the set up data as soon as the trigger is engaged again In case of improper running or bad functioning open the low pressure nozzle of the lance 9 and sto
