Maintenance Instructions

WARNING: Unauthorized machine modification or use of non-approved replacement parts may cause personal injury and/or property damage and will void the manufacturer warranty.

See Engine manual for engine maintenance.

Maintenance Mode

Water Filter

Check whether dangerous chemicals have been used, and take precautions when handling filters. Before each use, remove filter screen and rinse with clear water.

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 cracked, worn, or leaking.

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 mesh is exposed.
