On the Hydra M and Pro IV, check the hydraulic oil level on the dipstick, the engine oil and the gasoline every day, keep the upper packing lubricated and clean the paint filters before they load up. Titan's schedule for these models is to change the hydraulic fluid (Coolflo) and the external hydraulic filter every six months, not the twelve months used for the Hydra X.
The schedule at a glance
These intervals come from Titan's owner's manuals for the Hydra M 2000 / M 4000 and the Hydra Pro IV. The Hydra X is on a different schedule with a twelve-month fluid change, so do not carry its intervals over to these older sprayers. The two older manuals agree on the hydraulic fluid and filter interval. They differ on a few engine intervals, so Pro IV owners should read their own manual for the engine items.
Hydra M and Pro IV maintenance at a glance
| When | Task | Source |
|---|---|---|
| Every day | Hydraulic fluid level reads Full on the dipstick; engine oil and gasoline checked; paint filters cleaned after each job | Hydra M and Pro IV manuals |
| Every week | Clean the engine air filter element (daily if the site is dusty) | Hydra M manual |
| First 20 hours, then every 100 hours | Change engine oil; clean sediment cup, clean and re-gap the spark plug, clean the spark arrestor (100 hours) | Hydra M manual |
| Every six months | Change the hydraulic fluid and the external hydraulic filter | Hydra M and Pro IV manuals |
The Pro IV manual shows different engine hour intervals. Use the interval table in your own manual for the engine items.
Daily checks
- Hydraulic fluid. Pull the dipstick and confirm it reads Full.
- Engine oil and gasoline. Both are daily checks in the Hydra M manual. Use the fuel and oil rules in your engine manual and fill only outdoors or in a ventilated area, away from ignition sources.
- Paint filters. Clean the gun filter and the pump or outlet filters after each job, and before they load up. Per the Hydra M manual, that is how you avoid a surging pattern.
Upper packing lubricant. The Pro IV manual calls for Piston Lube (314-480) in the upper packing and says not to substitute water or paint solvent. On the Hydra M, use the wet-cup fluid your manual specifies. In the Hydra X manual, topping up is a daily task; for these older models, follow the interval in your manual, and a glance at the wet cup when you check the dipstick costs nothing.
Every six months: hydraulic fluid and filter
Titan's Hydra M and Pro IV manuals give a six-month interval for changing the hydraulic fluid, which takes 5 gal of Coolflo, and the external hydraulic filter. Coolflo is the hydraulic fluid Titan specifies, and the manual says not to use any other. The site sells it by the gallon (430-361) and the quart (430-362), so a full change means five of the gallon size.
Add fluid only in a clean, dust-free area, the manual says, and after the change run the sprayer at low pressure for at least 10 minutes. The same manuals say the hydraulic pump is not field-serviceable, so a hydraulic pump fault goes back to Titan.
Hydraulic filter parts on the site
Open the page for your model to see them: Hydra M and Pro Super Engine Drive and Hydraulic System, or the Pro IV Hydraulic System. The two numbers are not interchangeable: one is an element, the other is a filter assembly.
Engine items
Titan's Hydra M and Hydra X manuals give the same engine routine, which makes it a safe reference for the Hydra M. Change the oil after the first 20 hours and then every 100 hours, using SAE 10W30. Every 100 hours also clean the sediment cup, clean and re-gap the spark plug and clean the spark arrestor. Titan names an NGK BP6ES or BPR6E plug with a gap of 0.028 to 0.031 in. Clean the air filter element weekly, or daily on a dusty site.
Paint filters and strainers
A partly blocked filter causes pressure loss, pulsing and spitting, which is easy to mistake for a pump fault. These diagrams list the filter parts for the older Hydras:
- 920-004 Filter Element, 50 Mesh and 920-927 Long Body Filter, on the outlet accessories pages (Hydra M and Pro IV).
- 920-005 Manifold Filter and 920-050 Filter Service Kit, on the M4000 Accessories and M2000 Accessories pages.
- 103-629 Rock Catcher Assy, listed on the M4000 siphon hose page and the accessories pages. The Pro IV manual describes a rock-catcher inlet filter and a 50 mesh outlet filter on that model.
- 0509762A Inlet Screen, on the Pro IV siphon valve page.
For small tips, Titan's manual says to use a 100 mesh gun screen instead of a 50 mesh one. Titan does not publish a service life for any of these filters, so clean them on the schedule above and replace them when they are damaged or will not clean. The site does not list the contents of the 920-050 kit, so call us to confirm what it covers.
Pressure relief reminder
Storage and parts to keep
For extended idle time, the Hydra X, Hydra M and Pro IV manuals all call for kerosene and an oil preservative, not leaving coating in the pump. Follow the cleaning and storage section of your manual for the exact method.
- Coolflo: 430-361 by the gallon, enough for the six-month change.
- The hydraulic filter element or assembly for your model (432-864 or 432-861).
- Piston Lube 314-480 for the upper packing, where your manual calls for it.
- One or two spare outlet filter elements (920-004) and the 920-050 filter service kit.
- A spare dipstick assembly, 335-010A.
Maintenance parts for the older Hydra models:
The Short Version
Daily: dipstick, engine oil and gasoline, and clean the filters after each job. Weekly: engine air filter. Every 100 hours: engine service. Every six months: Coolflo and the external hydraulic filter. Do not use the Hydra X twelve-month interval, and read your own manual for the Pro IV engine intervals.
