Before starting a PowrTwin, check the hydraulic level at Full, fill the packing oil cup half full with Piston Lube, check engine oil and fuel, ground the sprayer and strain the paint. Set pressure only high enough to atomise. To shut down, lock the gun, turn pressure fully counterclockwise, stop the engine or motor, close the hydraulic shut-off valve and open the bleed valve into a grounded metal container.
This checklist covers the daily checks, start-up, pressure setting and the pressure relief procedure, in the order you meet them on a job.
Before you start
Titan's manuals build the daily routine around a handful of checks. They take a few minutes and prevent most of the early-morning problems.
- Hydraulic fluid. Read the dipstick against the Full mark. Titan requires Coolflo and says not to use any other fluid (430-361).
- Packing oil cup. Fill it half full with Piston Lube 314-480 and do not overfill.
- Inlet screen. Clean it. The manuals say at least once a day.
- Engine oil and fuel on a gas model. Fuel and run gas engines only outdoors or in a ventilated area, away from ignition sources.
- Grounding. Ground the sprayer and the gun, as the manuals direct.
- Hose. Use at least 50 ft of nylon airless hose.
- Paint. Strain it before it goes in the pail.
- Position. With flammable coatings, keep the sprayer outside the spraying area.
On an electric model, also check the power supply. Titan lists a 20 amp outlet and, if you need an extension cord, a grounded 3-wire #12 cord.
A new sprayer
The Plus manual says a new sprayer ships with test fluid in the fluid section. Before the first coating, flush the test fluid out with mineral spirits for 15 to 30 seconds, with the bleed hose in a metal container. Do not skip this step.
Starting and setting pressure
The manuals' start-up sequence has you confirm the pressure control, the hydraulic shut-off valve and the bleed valve before the engine or motor runs, so read that page of your manual rather than relying on a summary. Two points from the manuals apply to every model:
- Run a gas engine at the lowest speed that works. Higher engine speed does not raise working pressure.
- Turn the pressure up only until the spray atomises. Extra pressure wears the tip faster and adds overspray.
Gun, tip and hose matter as well. The tip you choose and the number of guns set the maximum tip size, and the system's hose and gun must be rated for the pressure. If you add guns, the manuals call for a manifold on the single gun outlet with the unused outlets plugged. Our 975-312 is the 2-gun manifold with ball valves, and the 538072 RX-Apex gun fits the PowrTwin 4900, 6900, 8900 and 12000.
Shutting down and relieving pressure
Do this when the job is done, before cleaning, before changing a tip or any part, and any time you stop work. This is the sequence in the Plus manual, in summary:
Lock the gun
Engage the trigger lock.
Pressure control to minimum
Turn the pressure control fully counterclockwise and shut off the engine or motor.
Close the hydraulic shut-off valve
Close it as your manual shows.
Trigger into a grounded metal container
Release the lock and trigger the gun against the side of a grounded metal container to release pressure, then lock the gun again.
Open the bleed valve
Put the bleed hose in the container and open the bleed valve.
The bleed valve is the part you operate on every shutdown, so its seat and ball are the parts that wear. The valve on the Plus models is shown on the Plus 6900 and Plus 8900 bleed valve pages, which list the outlet valve seat 0294516, the outlet valve ball 9841502 and service kit 944-050. Titan's troubleshooting tables name a worn or open bleed valve among the causes of a pump that runs slowly with the gun off.
Injection hazard and the tip
- Lock the gun before you change a tip or clear a clog.
- To clear a clogged reversible tip, rotate it 180 degrees and trigger once. Never trigger more than once with the tip reversed.
- Never spray without the tip guard fitted.
- After any suspected injection, go to a doctor immediately and say what the fluid was.

The Short Version
Check fluid, Piston Lube, screen and fuel, ground everything and strain the paint. Flush a new unit with mineral spirits. Set the lowest pressure that atomises. Shut down in order: lock the gun, pressure to minimum, stop, close the shut-off valve, trigger into a grounded metal container, open the bleed valve.
