Checking the Hoses
WARNING: Do not use a finger or skin to check for
leaks. Escaping fluid under pressure has sufficient
force to penetrate the skin, causing serious injury.
Do not operate the pressure washer if the hose is

Before each use check all hoses for leaks and worn
areas. Discontinue use of any hose if leaks are noticed.
Discontinue use of the high-pressure hose if the wire
