PowrLiner 9900XLT

PowrLiner 9900XLT Replacement Parts & Accessories

The PowrLiner 9900XLT is a professional-grade, ride-behind line striping machine engineered for the toughest and most extensive marking jobs. This hydraulic piston-driven system offers high output, robust construction, and precise control, ideal for jobs where speed, consistency, and reliability are essential.

 The 9900XLT features a self-propelled PowrHandler drive system that helps operators cover large surfaces faster and with less effort than traditional walk-behind stripers. With versatile power options (gas, electric, or both) and contractor-level durability, the PowrLiner 9900XLT makes industrial-scale striping efficient and productive.

Key Features

• Self-Propelled Hydraulics: Integrated hydraulic drive system increases productivity on large projects by propelling the unit with variable speed control. 
• Flexible Power Options: Power choices include gas or electric operation to suit different job site conditions.
• High Operating Pressure: Designed to maintain up to 3300 psi for smooth atomization and professional striping finishes.
• Freeze-Proof Pressure Control: Helps maintain consistent pressure in cold environments, reducing downtime.
• Large Capacity Paint Handling: Includes standard siphon hose and bleed line assemblies for efficient paint feed and bleed-off.
• Easy Forward/Reverse Controls: Spring-loaded rocker switch for intuitive direction changes during striping.
• Transaxle Drive: Ensures steady power and traction over uneven or sloped surfaces to keep lines straight and consistent. 

Applications

The PowrLiner 9900XLT is built for large-scale and professional marking tasks, including:

• Airport runway and taxiway striping – precision marking over wide expanses. 
• Roadway and highway line painting – consistent, professional results at high speeds. 
• Parking lot layout and marking – durable lines for commercial facilities.
• Athletic fields and courts – high-output visibility lines for multiple sports.
• Municipal and industrial striping – efficient coverage for large-area marking needs. 

FAQs 

1. How often should I clean the paint system on the PowrLiner 9900XLT?

After each major stripping job, flush the paint hoses, siphon assemblies, and valves to prevent buildup. Regular cleaning helps maintain clear fluid paths and reduces the risk of clogs that can disrupt spray quality. 

2. What should I check if the striping pressure fluctuates?

Pressure changes often come from partial clogs in filters or siphon hoses, worn valves, or paint contamination. Inspect and clean filters and siphon lines regularly to maintain stable pressure. 

3. How do I maintain the hydraulic system?

Check hydraulic fluid levels and hose connections periodically, and inspect the PowrHandler drive system for leaks or wear. Regular maintenance prevents performance loss and extends component life. 

4. What maintenance does the engine (gas model) require?

For gas-powered units, follow standard small engine care: check oil levels, replace or clean air filters, and inspect spark plugs. Clean any dust or paint overspray from engine components to avoid heat build-up.

5. Why should I inspect the front caster and transmission assembly regularly?

The front caster and drive transaxle control steering and traction. Debris buildup or worn bearings can affect tracking accuracy. Regularly inspect and clean these parts to ensure straight and accurate line striping at all speeds.
