Why does my Craftsman 580.767450 Pressure Washer have low or erratic pressure?

If your Craftsman Pressure Washer pump isn't producing pressure, has erratic pressure, chatters, loses pressure, or has low water volume, here's what you can check: * Ensure the nozzle is in high pressure mode by pulling it backward. * Clear any blockages in the water inlet. * Make sure the water supply is adequate. * Straighten any kinks in the inlet hose and patch any leaks. * Check and clean the inlet hose strainer. * Ensure the water supply is not over 100°F; use cooler water. * Clear any blockages in the high pressure hose. * If the gun leaks, replace it. * Clean any obstructions in the nozzle. * If the pump is faulty, contact a Sears service facility.
