Specifications

Setup

1. Inspect Hose: Before each use, visually inspect the entire length of the hose for any signs of damage, cuts, abrasions, bulges, or kinks. Check the connectors for wear or damage. Do not use a damaged hose.
2. Ensure Compatibility: Verify that the hose's pressure rating (7250 PSI) meets or exceeds the maximum output pressure of your equipment. Ensure the connectors are compatible with your pressure washer and spray gun/accessory.
3. Connect Securely: Attach one end of the hose to the pressure washer's high-pressure outlet and the other end to the spray gun or accessory. Hand-tighten the connections firmly. Use a wrench for a final snug fit, but do not overtighten, as this can damage the threads or seals.
4. Check for Leaks: Before starting the pressure washer, ensure all connections are tight and free of leaks. A small drip can indicate a loose connection or a damaged O-ring.

Operating

• Maintain Proper Distance: Keep the hose clear of moving parts, sharp objects, and hot surfaces.
• Avoid Kinks: Always uncoil the hose completely before use to prevent kinks, which can weaken the hose structure and lead to premature failure.
• Manage Pressure: Do not exceed the hose's maximum rated pressure. Operate the pressure washer according to its own manual.
• Handle with Care: Do not pull the pressure washer by the hose. Move the pressure washer closer to your work area as needed.
• Relieve Pressure: Always relieve system pressure before disconnecting the hose or performing any maintenance.

Maintenance

• Regular Inspection: Periodically inspect the hose for any signs of wear, damage, or leaks, especially at the connection points. Replace the hose immediately if any damage is found.
• Cleaning: After each use, rinse the hose with clean water to remove any dirt, chemicals, or debris.
• Proper Storage: Coil the hose neatly after use. Store it in a cool, dry place, away from direct sunlight, extreme temperatures, and corrosive chemicals. Avoid storing the hose with kinks or sharp bends.
• Connector Care: Keep the hose connectors clean and free of debris. Lubricate O-rings with silicone grease if they appear dry or cracked to maintain a good seal.

Troubleshooting

• Leaks at Connections:
  • Ensure connections are tightened securely.
  • Check O-rings for damage or wear; replace if necessary.
  • Inspect threads on both the hose and equipment for damage.
• Hose Kinks or Twists:
  • Always uncoil the hose completely before use.
  • Avoid dragging the hose around sharp corners or obstacles.
  • If a kink occurs, relieve pressure and straighten the hose before resuming operation.
• Reduced Pressure/Flow:
  • Check for kinks or blockages within the hose.
  • Ensure the pressure washer's water supply is adequate.
  • Verify that the pressure washer itself is operating correctly.
