Operation Instructions
1.) Make sure the water supply is clean. Debris can cause excess pump wear and reduce performance.
2.) An insufficient water supply will damage your pump. Make sure the water supply is steady and is 20% over the rated flow of your pump. Use a stopwatch to time how long it takes to fill a 5 gallon bucket with your garden hose. The bucket must be filled faster than 100 seconds.
3.) The water supply garden hose must have an inside diameter of at least 5/8”. If the hose is more than 100 ft. long, the diameter must be at least 3/4”.
4.) Never use a reservoir tank as a water source. Drawing water out of a tank may cause pump cavitation and damage to your pump. This pressure washer is designed for a pressurized water source such as a city water faucet. However, the water source pressure must not exceed 115 psi (8 bar).
5.) Always use a flexible rubber hose for your water supply. Do not use rigid piping.
