FAQ’s

1. What does the PowrTwin 4900GH Filter Assembly do, and how often should it be serviced?

The filter assembly removes debris and contaminants before they enter the pump and hose. Regular cleaning is recommended daily or whenever material flow becomes inconsistent. The internal screen should be replaced if damaged or clogged.

2. What is the purpose of the Bleed Valve Assembly?

The bleed valve assembly helps release trapped air from the hydraulic pump and fluid section during priming. If the sprayer fails to prime or pressure fluctuates, checking the bleed valve for blockage or worn seals is essential.

3. How does the Hydraulic Motor affect performance?

The hydraulic motor drives the pump with consistent power, reducing pulsation and improving spray quality. If you notice slow cycling or poor pressure, it may indicate worn seals or internal hydraulic leaks within the motor assembly.

4. Why is the Fluid Section important?

The fluid section is the heart of the sprayer; it hoses the piston, packings, rods, and cylinders that pressurize paint. Replacing packings and lubricating this section ensures long pump life and prevents pressure loss.

5. What does the Siphon Hose Assembly do, and when should it be replaced?

The siphon hose pulls material from the bucket into the sprayer. Cracks, clogs, hardened hoses, or air leaks can cause priming issues or low pressure. Replace the hose if it appears stiff, damaged, or heavily worn.
