On a hydraulic PowrLiner 4955, 6955 or 8955, check the Coolflo level on the dipstick each day before you start, up to the Full mark, and use no other hydraulic fluid. Keep the packing oil cup half full of Piston Lube, check the engine oil, clean the filters after every job, and follow the manual's pressure relief procedure before you service anything.
Before you start the engine
These checks apply to the hydraulic PowrLiner 4955, 6955 and 8955. The 850 and the 3500 have different drives and different routines, so use their own manuals. Most of what follows comes from Titan's manual for the three hydraulic models, which is the document to follow whenever this page and your machine disagree.
Check the hydraulic fluid
The manual has you check the level daily before starting, up to the Full mark on the dipstick. The dipstick is 449-626 and the tank is 449-718A, both on the hydraulic system page for your model.
Check the engine oil
The units ship with engine oil in the engine, and the manual tells you to check the level before the first start. Checking it each day is sensible practice, since the gas engine drives the whole system.
Check the packing oil cup
The manual says to fill the oil cup half full with Piston Lube. Top it up with 314-480 if it is low.
Look at the hose, gun and tip guard
Confirm the tip guard is fitted and the gun's trigger lock works before you pressurize anything.
Fuel outdoors, away from ignition sources
Run and fuel the engine outdoors or in a ventilated area, away from sparks and open flames.
Coolflo is the only fluid
Titan's manual makes Coolflo mandatory in the 4955, 6955 and 8955 hydraulic system and says not to use any other hydraulic fluid. Do not top off with whatever is on the truck. We list it as 430-361 by the gallon and 430-362 by the quart, and the 430-362 listing names PowrLiner among the compatible series.
Titan's manual excerpts we have do not give a change interval for the hydraulic oil, so we do not quote one. The manual for your machine is where the change schedule and the fill procedure live. If the level keeps dropping between checks, treat that as a leak to find, not a habit to top off.
Packing lubricant
The fluid section of these machines is a piston pump, so the piston rod moves through packings. Titan says Piston Lube prevents increased wear and tear of the packings, and the manual's instruction is to fill the oil cup half full. The site lists 314-480 in the 8 oz size and 314-481 as the 4 oz bottle.
Why it matters: packings that run dry wear faster, and worn packings let pressure leak off. A pump that will not hold pressure is the cue to look at the packings and the piston or displacement rod. The fluid section pages for your model, such as the 4955 fluid section, list the repacking sets and the rod.
Filters and the high pressure filter
An airless system usually has three filter points: the inlet screen on the suction side, the manifold filter in the high pressure filter housing, and a filter in the gun. A partly blocked filter causes pressure loss, pulsing and spitting, and cleaning a filter is the least expensive fix for all three, so clean them after every job and use the mesh that suits the coating.
- Inlet screen: 0509762A, on the main assembly pages and the accessories page.
- Manifold filter: 930-006 on the 4955 high pressure filter page. The 6955 and 8955 pages list more than one manifold filter number (930-005, 930-006 and 930-007), so confirm which one your machine uses.
- Filter service kit: 930-050 on the high pressure filter pages.
- Hydraulic filter: 451-220 on the hydraulic system pages. This filters the oil, not the paint, and Titan's excerpts we have do not give a change interval.
The diagrams are model specific. Open the 4955 high pressure filter page, or the 8955 hydraulic system and 6955 hydraulic system pages, and match the callout rather than ordering by name.
Shutting down
- Relieve pressure as the manual describes.
- Flush and clean the pump, hose and gun after every use. Never leave latex or other coating to dry in the pump, hose or gun.
- Clean the filters, as above.
- Check the Coolflo level and the Piston Lube cup so the machine is ready for next time.
- For storage, follow the manual's instructions for your coating and for freezing weather. Liquid Shield, 314-482, is a Titan product we sell, and the manual covers how it is used.
What to keep on hand
A hydraulic striper stops for small things, so a short shelf covers most early downtime: Coolflo, Piston Lube, a hydraulic filter, a filter service kit and the right fluid section kit for your model. Fluid section part numbers differ between the 4955, 6955 and 8955, so use the diagram for your model: for example 106-002A on the 4955, and 138-153A on both the 6955 and the 8955. The 4955 accessories page lists the consumables in one place.

The Short Version
Every day: Coolflo to the Full mark, engine oil, the Piston Lube cup half full, clean filters, tip guard on. Every shutdown: relieve pressure per the manual, flush and clean. Use only Coolflo, and take intervals from your manual. Call (713) 931-0006 if you are not sure which diagram page or kit matches your machine.
