After servicing the filter, reconnect it securely. Then, run the machine for a few minutes to ensure proper flow and check for leaks. A clean and functional filter is key to efficient performance.
Test the Gun and Lance for Blockages
Detach the lance from the unit and inspect it closely for any obstructions. A blocked lance can severely restrict water flow, making it difficult to achieve the desired cleaning results. Use a thin wire or a pin to clear any debris from the nozzle. After clearing, reconnect the lance and run a test to check for an improvement in performance.
Check the Gun
Next, focus on the gun assembly. Remove the nozzle from the gun and examine the inlet for any blockages. Ensure that the gun operates smoothly without any irregularities in the trigger action. If the trigger feels stuck or sluggish, clean the contact areas thoroughly and check for any signs of wear that could affect functionality.
Conduct a Flow Test
Perform a flow test by reattaching the lance and directing the gun towards a suitable surface, such as a wall or driveway. Activate the trigger to observe the spray pattern. A steady, powerful stream indicates that the gun and lance are clear. If the pattern is weak or inconsistent, further cleaning may be required. Regular maintenance on these components is key to optimal operation.
Assess the Nozzle for Clogs or Damage
Begin the assessment by removing the nozzle from the lance. Inspect it visually for any debris that may have lodged inside. A blockage can severely reduce water flow or create uneven spray patterns, leading to subpar results.
To clear any obstructions, use a fine wire or a soft brush. Be cautious with the wire to avoid damaging the nozzle opening; it must remain perfectly shaped to function correctly. After cleaning, run water through the nozzle to ensure it’s clear.
Check for Physical Damage
Examine the nozzle for cracks or other signs of wear. Even small damages can impede performance. If you find any, consider replacing the nozzle, as a compromised part can lead to pressure loss.
