All safety information should be observed and failure to comply with instructions could result in personal injury and/or property damage. The water supply should be clean and free of debris that can cause excess pump wear and reduce performance. An insufficient water supply can damage the pump, so ensure that the water supply is steady and is 20% over the rated flow of the pump. 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.

TIPS:

• When your engine shaft length is longer from the engine flange (PTO) to the shaft end, when you set up the engine shaft and pump, you will find the gap between the pump boss and the engine bottom or flange.
• Then you need to put the washer into the gap, between your original engine flange and pump boss, then screw up the bolt for some engines, need washers for all three pump bosses.

OPERATION TIPS

Water Supply:

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.
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). Always use a flexible rubber hose for your water supply. Do not use rigid piping.
