After each job, empty the cup, run the cleaner recommended for your coating through the gun until it comes out clear, wipe the outside and clear the air holes without metal tools. Take the check valve apart and clean it, but do not soak its hoses in hot solvent. Then check the filters at the other end of the system.
Why the cleaning happens before you pack up
Coating left to dry in a gun causes trouble on the next job, and the manuals say so in their own terms: a check valve that is not cleaned causes trouble the next time you spray. Titan's blog describes cleanup on an HVLP system as mainly the gun and cup, with the check valve taken apart and cleaned, plus regular cleaning of the hose. On a turbine system that is short work, and it is far shorter than chasing dried material out of the gun later.
The same logic applies to any sprayer: flush and clean it after every use, and never leave a coating to dry in the gun or the hose. What follows is the CapSpray version, gun end first.
Cup and gun
Empty the cup
Pour out what is left in the cup before you add anything else to it.
Run cleaner through the gun
Put the cleaner recommended for your coating in the cup and run it through the gun until it comes out clear. The coating maker's label, not this page, tells you which cleaner that is.
Wipe the outside
Wipe down the gun and the cup. Dried material around the cup and the air cap is easy to miss and easy to wipe off while it is fresh.
Clear the air holes and passages
Keep the air holes and passages in the gun clean. Never use metal tools on the air cap or the nozzle; a scratched nozzle or air cap is not worth the saved minute.
Clean air cap holes matter more than they look. The Maxum II manual lists clogged air cap holes as a cause of pulsating spray, so a minute spent on them after the job is cheaper than the pulsing you diagnose at the start of the next one.
The check valve
The manuals single out the check valve. Take it apart, clean it and put it back together after each use. Do not soak the check-valve hoses in hot solvent. An uncleaned check valve is the thing the manuals warn will cause trouble the next time you spray, so it is the step to do if you only have time for one.
Titan's instruction for reassembly is to lubricate the gun threads with petroleum jelly. Do that as you put the gun back together, not as an afterthought. On the Maxum II, the manual also lists a faulty valve in the air tube as one cause of spitting, and the fix is to replace the valve assembly, so a check valve that looks damaged while you have it apart is a reason to call us instead of reassembling it.
The turbine end: filters
Titan's blog says an HVLP system needs maintenance mainly on the filters at each end of the turbine, and it asks you to keep them free of dust and debris before and after use. In practice that is a look at both ends when you finish. Unplug the turbine first. If the filters are dusty, the manuals' method is to remove the covers by turning them counterclockwise, take out the pre-filter and filter on each side and tap or blow them out with compressed air.
If the red light came on during the job, treat it as a cleaning cue. The filter parts for each model are on the Main Assembly page, for example the CapSpray 115 Main Assembly.
Where things live between jobs
- Toolbox. Every CapSpray has an onboard toolbox for needles, nozzles, air caps and the nozzle wrench. The site lists it as 0524538 Tool Box, with the door as 0524537, on the Upper Housing diagram.
- Gun and cup holder. A built-in holder keeps the gun and cup on the turbine. The site lists a 0524536 Cup Holder (HVLP) on the 55 and 115 upper housing diagrams.
- Viscosity cup. The 0153165 Viscosity Cup is listed on the Main Assembly diagram, so keep it where you will find it before the next job.
- Maintenance kits. Titan sells maintenance kits for the Maxum II and Maxum Elite guns. We do not list the contents here, so ask our parts team which kit applies to your gun.
Titan does not publish storage temperature or storage-time guidance for the turbine or the guns, so we do not give any. For storage beyond a clean, dry unit with its small parts in the toolbox, read the storage section of your model's manual on our manuals page.

The Short Version
Empty the cup, run the right cleaner through the gun until it is clear, wipe it, keep air holes clear without metal tools, and take the check valve apart every time. Look at the filters at both ends of the turbine, put the nozzles and wrench back in the toolbox and you are ready for the next job.
