3. event of a blockage STOP the pump immediately shut off the air at the air valve on the gun and perform the following as soon as possible Page 10 Blockage removal To remove the blockage all pressure inside the material hose must be relieved this can be done by leaving for a short period of time until the pressure naturally dissipates or by turning the pump to reverse for a couple of seconds NOTE Do not run the pump in reverse for more than a second or two or the blockage may get sucked back into the material hose requiring further removal and or the pump may become damaged e Once the pressure in the material hose is removed unclip the cam locks on the material hose connection and remove the hose from the back of the gun e Apply a water hose the front of the spray gun through the nozzle to flush out the blockage Doing this over a clean hard standing will allow the easier detection of the blockage allowing the reason for blockage to be determined easier e Keep flushing the spray gun until a clear sight path can be established through the gun Pay particular attention to the material fitting when flushing e Turn the pump ON for approx 10 seconds with the material hose placed in a waste collection vessel allowing the contaminated material to purge from the pipe e Turn OFF the pump clean the hose end and reassemble the gun to the material hose making sure the cam locks are secure e Open the air
