A Step-by-step guide to trigger handle maintenance

Solo sprayers are designed to stand the test of time, and with good maintenance and TLC, you'll be pleasantly surprised by how these quality products last.

Trigger handle maintenance is integral to making sure your sprayer is in top condition, as chemical residue can play havoc with the pump, wand and trigger.

It can get a little technical, but chemicals left in the trigger handle can strip the lubricant around the O-Rings, causing wear. Just like it's best practice to flush your sprayer after every use, it’s also best practice to perform the following maintenance on your trigger every couple of months:


  1. Disconnect wand from trigger handle.
  2. Disconnect hose from the opposite end.
  3. Remove black pin holding trigger lever.
  4. Remove screw cap on upper side of trigger handle - caution: there is a spring inside.
  5. Push red valve body out of trigger handle. 
  6. Used compressed air or water jet to clean out cavities in trigger handle.
  7. Lubricate O rings on red valve body with Vaseline. Please do not use silicone/silicone grease.
  8. Reassemble in reverse order.

how to maintain your sprayer wand and trigger


The spray pattern will be affected if your sprayer’s nozzle becomes clogged with built-up debris or chemicals, so your sprayer will thank you for taking the time to clean the nozzle while you’re performing the above maintenance.

  1. Twist off the nozzle.
  2. You’ll see a white cylindrical filter and the nozzle shell. Wash these with some water.
  3. Give the nozzle casing a good blow through in the reverse direction - blow through from output end to remove any excess debris. When you'd done this, ensure the nozzle is free and clear.
  4. Reassemble in reverse order.

When we see sprayers that have been in action for 10, 20, 30+ years, they all have one thing in common – their owners have taken the time to clean them and keep them properly maintained. But don't worry - if your sprayer is looking a little worse-for-wear, or not working as efficiently as you'd like, we can help. Solo NZ can repair sprayers, or you can purchase additional parts (like new O-rings) to get it working again.
