PowrLiner 6900

PowrLiner 6900 Replacement Parts & Accessories

The PowrLiner 6900 is a heavy-duty, contractor-grade line-striping machine built for professionals who tackle large-scale marking jobs from parking lots and roadways to runways, athletic fields, and industrial sites. Designed with rugged reliability and long-term performance in mind, the 6900 combines a powerful engine, a robust hydraulic drive system, and a durable frame to deliver clean, consistent striping even under demanding conditions. Whether you’re doing large parking-area layouts, road markings, or full-scale re-striping, the 6900 offers the strength and efficiency that lets you work hard without worrying about equipment failure.

What makes the 6900 special is not just raw power; it’s its balance of precision, durability, and flexibility. The machine’s hydraulic drive gives smooth, steady pressure and fluid flow, while features like dual-gun capability, high-pressure tolerance, and heavy-duty construction ensure that it can handle everything from standard pavement paints to heavier or solvent-based coatings. For contractors who value reliability, versatility, and long service life, the PowrLiner 6900 is a trusted workhorse.

Key Features

Heavy-Duty Frame & Construction  Built on a robust, epoxy-finished frame designed to resist harsh solvents, corrosion, and rough job-site conditions. 

Powerful Hydraulic-Drive System & High-Pressure Output The 6900 is driven by a dependable gasoline engine (with convertibility options) that powers a hydraulic system capable of delivering up to ~3300 PSI (228 bar), allowing it to spray a wide range of coating materials from light-bodied paints to thick traffic paints. 

Large On-Board Hopper & Fluid Delivery Capacity  With a generous onboard paint hopper (about 45 L / 12 gal), the machine supports large jobs without frequent refills. 

Flexible Gun Configuration (1-Gun or 2-Gun Option)  The machine supports either single-gun or dual-gun setup, allowing either standard lines or wider/dual lines in a single pass, useful for double-lane parking markings, road lines, or high-output jobs.

Swivel-Caster Front Wheel + Pneumatic Tires for Smooth Operation and Precision Steering. The front caster locks into straight or curved line modes, helping operators maintain clean, accurate lines even on turns or radius layouts; pneumatic tires help absorb shocks on uneven surfaces. 

Versatile Power Options (Gas / Convertible Electric)  While the standard model uses a Honda 5.5 HP gasoline engine, the design accommodates a conversion kit for electric power, offering flexibility depending on job site restrictions or noise/emissions requirements. 

 Applications

The PowrLiner 6900 is suited for a broad range of professional striping and marking tasks, including:

• Large parking lots, commercial complexes, parking stalls, loading zones, fire lanes, directional arrows, crosswalks, and more.
• Roadways, local roads, and highway markings, lane lines, edge markings, pedestrian crossings, shoulder lines, etc.
• Airports, industrial areas, and logistics terminals require runway/taxiway markings, loading zones, safety zones, and industrial floor markings.
• Stadiums, sports fields, recreational parks, and athletic facilities include field boundaries, lane markings, parking zones, and pedestrian routes.
• Municipal infrastructure, maintenance, and large-scale repainting jobs are ideal for contractors handling frequent repainting or large-scale striping contracts where durability, reliability, and speed matter.
  
  

FAQ’s

Q1. What parts are included under the “Hydraulic System Assembly” , and why are they important?

This sub-category includes components such as the hydraulic motor, drive belts/guard, hydraulic pump, and associated fittings, all essential for powering the fluid pump. The hydraulic system ensures smooth, steady, slow-stroking pump action, which leads to consistent paint flow, longer pump life, and lower maintenance demands. 

Q2. When should I consider replacing parts in the “Fluid Section / Filter Assembly”?

If you notice poor spray quality, uneven flow, clogs, or difficulty priming, this might indicate worn or clogged filters, or degraded fluid-section components (like valves, seals, or hoses). Routine inspection and timely replacement help maintain consistent line quality and prevent pump damage.

Q3. What does the “Gas Convertokit” or “DC Electric Convertokit”  mean, and when would I use it?

These kits allow you to convert the standard gas converto kits into an electric-powered unit. This is useful when working indoors, in restricted zones, or where noise and emissions must be minimized. It gives you flexibility in different working environments without buying an entirely different machine. 

Q4. Why and when would I install a “Second Gun Assembly”?

Adding a second gun allows you to spray two parallel lines or wider lines simultaneously, which significantly improves productivity on wide lots or long road jobs (like parking lots or double-lane markings). It helps save time and ensures uniform line application

Q5. What maintenance should be done to ensure long-term performance of the 6900’s pump and hydraulic system?

You should regularly check hydraulic fluid levels, use proper hydraulic motors, inspect hoses for wear or damage, check filters and valves, and replace worn seals or packings as required. Proper maintenance ensures consistent pressure, prolongs pump life, and maintains reliable operation even under heavy use.
