Titan Paint Sprayer Troubleshooting

A favorite with many contractors, tradespeople, and hardcore DIYers, Titan paint sprayers are some of the most reliable and robust you will find in today’s market. However, even these giants in the world of painting technology sometimes aren’t immune to problems. When issues crop up, Titan paint sprayer troubleshooting knowledge can be a godsend.

While these machines are covered by extensive warranties and market-leading technical support — there are steps you can take yourself before going down this route.

Let’s look at our favorite Titan paint sprayers, and then delve into some reasons why they aren’t performing and the solutions.

Titan Paint Sprayer Troubleshooting Tips

Whether you’re a DIY aficionado or a seasoned professional, issues with your sprayer can be a real source of frustration that can set you back both money and time.

With the Impact 440 being Titan’s most popular sprayer and the Control Max range also highly rated, I’ve concentrated my efforts on these models. The first set of tips apply to Titan 440i paint sprayer troubleshooting. Further down, I’ll cover the Titan Control Max series.

Titan Impact 440 Troubleshooting

1. Unit Doesn’t Run

While it might be stating the obvious, check you have a power supply and your unit is plugged in. When spraying, the plug may have worked loose, or the outlet you’re using could be faulty. However, once you have ascertained that the juice is flowing to your machine, take a look at the following possibilities:

  • The breaker has tripped — reset your breaker.
  • Pressure control knob is set to low — if you have this dialed down to a minimum, power won’t be supplied to your unit. Turn the knob clockwise to increase the pressure setting and power up your machine.
  • Loose or faulty wiring — examine the wiring on your unit. If it looks frayed or worn, take the machine to an authorized Titan technician.
  • Overheated motor — you’ve been painting away like a trojan and the temperature of your machine has risen excessively. Turn it off for a while and let it cool down.
  • Faulty on/off switch — replace the switch with a new one.

2. Unit Fails to Prime

Priming your paint sprayer prepares it to dispense your chosen material. When this fails to happen, your sprayer won’t work. Here is a checklist to follow when you find this function is absent.

  • PRIME/SPRAY valve is set in the wrong position — turn the dial from SPRAY to PRIME by turning it clockwise.
  • Air leak in the suction/siphon tube set area — inspect the connection on the suction/siphon tube set and tighten if necessary. You can always use PTFE tape to ensure a secure fit.
  • Clogged inlet screen or pump filter — remove these components and clean them before refitting and repriming.
  • Blockage in the suction tube/siphon set — take out the tube set and clean it.

3. Machine Doesn’t Build or Maintain Pressure

Paint sprayers work by using pressure to atomize paint into a fine mist to deliver a flawless finish. Without the correct pressure, you either don’t receive decent coverage or no spray at all. There are numerous reasons this can occur, so if this is happening to you, test them one by one.

  • Worn spray tip — replace your spray tip according to your owner’s manual.
  • You’re using a spray tip that’s too big — use a spray tip with a smaller opening.
  • Pressure control dial is set too low — ramp up the pressure by turning the pressure control dial clockwise.
  • Clogs in the pump filter, inlet screen, or gun filter — remove these filters one at a time and clean away any dried paint or debris. Replace if necessary.
  • Fluid escapes from the return hose when the PRIME/SPRAY valve is set to spray — check the valve and either clean or replace it.
  • Siphon/suction tube set has an air leak — tighten or re-tape the tube with PTFE tape.
  • External material leak — inspect all connections for leaking air and tighten any that are loose.
  • Worn, dirty, or dry packings or worn valve balls causing internal fluid leaks — service the fluid section following directions in the manufacturer’s manual, or clean the valves.
  • Valve seats are worn — try reversing the valve seat or replace it in line with the manufacturer’s maintenance guide.
  • Motor fails to rotate with power on — your machine needs to be taken to a Titan authorized technician.

4. Material Leaks From The Upper Part of the Fluid Section

Leaks from a paint sprayer are never good news, no matter where they occur. If it’s in the upper fluid section, check for:

  • Worn upper packings — repack the pump following the section on ‘Servicing the Fluid Section’ in your owner’s manual.
  • Worn piston rod — replace the piston rod.

5. Too Much Surge at the Spray Gun

If your spray gun is surging or pulsating when you paint, you will end up with an uneven finish. Try following these tips to resolve the problem.

  • Incorrect airless hose fitted — change the hose. Fit a new quarter-inch grounded textile braid hose that’s at least 50 feet in length.
  • Spray tip is too big or worn — use a smaller spray tip or replace one that has seen better days.
  • Pressure is too high — dial down the pressure by turning the control knob counterclockwise.

6. Inadequate Spray Pattern

The whole idea of possessing and using a spray gun is that it’s efficient and delivers a superior finish to your paintwork. If it isn’t performing as you would like, try the following:

  • Spray tip is too big for the material you’re applying — use a smaller spray tip to attain correct atomization.
  • Pressure setting is wrong — adjust the pressure with the control knob until you get the spray how you want it.
  • Fluid delivery is insufficient — check all filters and screens for clogging and clean as necessary.
  • Spraying material that’s too thick — dilute your material according to the recommendations from the manufacturer.

7. Lack Of Power

There are a couple of reasons why your machine is lacking the power to spray. These include:

  • Not enough pressure — turn the pressure control knob up to a higher setting.
  • Wrong voltage supply — make sure you’re connected to a 120V AC input.

Titan Control Max Series Troubleshooting

The popular Titan Control Max range is a line-up of high-efficiency airless machines favored by many for applying sealers and stains. Like any other electrical appliance, they’re awesome when they function correctly — but what happens when problems crop up?

I’ve put together some common malfunction issues that you can check.

1. Sprayer Doesn’t Power Up

  • Not plugged in — yes, I know it’s obvious, but we’ve all done it. Make sure your sprayer is connected to a suitable power outlet.
  • Pressure control knob isn’t on — ensure the pressure control knob isn’t in the OFF position.
  • Sprayer stops when under pressure —it’s normal for the sprayer to cycle on and off when you’re painting. It helps keep the pressure regulated.
  • Power outlet is faulty — check your circuit breaker. Reset it if necessary, or change to another power outlet.
  • Extension cord is damaged or not correct for the machine — the extension cord you use should be in good repair and heavy enough for the current your sprayer demands. It should be a 12 or 14 gauge cord, and the recommendation is a length of between 20 and 35 feet.
  • Clogged spray tip — clean your spray tip to remove debris.
  • Issue with sprayer motor — this is a job for the experts, so consult Titan technical service.

2. Sprayer Fails to Draw Material

You’ve set your Titan paint sprayer up and are all ready to begin work when you notice that material is not drawing through the system, although it’s set to PRIME. The main culprit of this is generally a blockage somewhere in the system. These are the parts you need to check:

  • Inlet valve — to clear a clogged inlet valve, push the pusher stem to release it, and if that doesn’t work, clean it.
  • No suction at the inlet valve — test the suction tube for suction. Remove the tube and place your finger over the end. If it isn’t drawing, the inlet valve could require cleaning.
  • Damaged or blocked suction tube — replace your suction tube.
  • Suction tube isn’t installed properly — reinstall your suction tube correctly.
  • Clogged inlet filter — clean or replace the inlet filter.
  • Outlet valve contains debris or is stuck — clean the outlet valve or replace it if necessary.
  • Either inlet or outlet valve is damaged or worn — replace one or both valves.
  • Plugged PRIME/SPRAY valve — contact an approved Titan technician.

3. Pressure Drop Outs

If your sprayer is drawing up material, but when you trigger the gun, the pressure drops, you could be experiencing either no spray or an inconsistent spray pattern. This can be frustrating when all you want to do is get on with the job in hand. Here are some of the causes and solutions to get you painting again.

  • Low pressure — crank up the pressure control knob to a higher setting.
  • Worn spray tip — change the spray tip out for a new one.
  • Clogged inlet filter — clean the inlet filter, or replace it if necessary.
  • Plugged spray tip — clean the spray tip or replace it.
  • Material is too viscous — either thin the fluid down according to the manufacturer’s instructions or use a larger spray tip.
  • Paint is too coarse — strain your material before using it.
  • Damaged or worn outlet valve assembly — exchange the outlet valve for a new one.
  • Spray hose too long — shorten the hose length.
  • Filter accessory (if fitted) is clogged or dirty — clean this part and change it out if required.

4. Material Flows Through Return Tube

You’ve set your PRIME/SPRAY knob to the SPRAY position but the fluid is flowing through the return tube. If this happens, the chances are your PRIME/SPRAY valve is dirty or worn, and you need to consult Titan technical service.

5. Leaky Spray Gun

Internal parts under the hood of your spray gun that are dirty or worn can cause leaks. The recourse here is to speak to a qualified Titan technician to put it right.

6. Leaks From the Spray Tip Assembly

A leaky spray tip can be very annoying. It will drip paint where you don’t want it, ruining your paintwork and everything around it. There are some simple fixes to resolve the issue.

  • Loose tip guard nut — use a wrench to gently tighten the nut on the tip guard.
  • Incorrect tip guard assembly — remove the tip guard and make sure it’s assembled correctly.
  • Worn tip seal — change out the tip seal.

7. Spray Gun Doesn’t Spray

You’re raring to go on your latest painting project, but your gun isn’t playing the game. When you depress the trigger, zero spray comes out. Try these adjustments to get it working again.

  • Clogged spray tip — clear the tip of debris by rotating it 180 degrees and spray onto some scrap cardboard or metal. Ensure you lock and unlock the spray gun before and after turning the spray tip, and that the PRIME/SPRAY knob is set to SPRAY.
  • Spray tip is in the wrong position — check the spray tip is set to SPRAY.
  • PRIME/SPRAY knob is set to PRIME — turn the PRIME/SPRAY knob to SPRAY.
  • Clogged or dirty filter accessory — clean or replace the filter accessory.

8. Poor Spray Pattern

Nailing your spray pattern is key to the flawless finish you expect from a Titan paint sprayer. If you notice ‘tailing’ — the edges of your spray pattern displaying visible lines — there are a few things that could be causing it.

  • Low pressure — increase the pressure via the pressure control knob.
  • Plugged spray tip — clear the spray tip following the directions in your owner’s manual.
  • Clogged inlet filter — clean or replace the filter.
  • Worn spray tip — replace the spray tip with a new one.
  • Too thick or heavy coating — thin down your material in line with recommendations from the manufacturer.
  • Spray hose is too long — if you have added extra length to your spray hose, remove it.

9. Spray Tip Won’t Rotate

In order to clear a blockage in the spray tip, you need to be able to rotate it through 180 degrees. If you attempt this and it won’t turn, the system pressure might have locked it in place.

To release it, turn the PRIME/SPRAY knob to PRIME, unlock the spray gun and squeeze the trigger — pointing the gun at a test surface. Release the trigger and lock the gun again — the pressure should release, allowing the spray tip to rotate.
