Operation Instructions

Water Supply

1.) Make sure 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 in less than 125 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.

Start-Up Instructions

1.) Attach garden hose to water inlet.

2.) Attach pressure hose to water outlet and spray gun.

3.) Attach spray gun to lance.

4.) Turn water supply ON.

5.) Squeeze trigger to purge air from water pump.

6.) Start engine.

Shut-Down Instructions 1.) Turn engine OFF.

2.) Turn water supply OFF.

3.) Squeeze trigger to relieve system pressure.

4.) Remove garden hose.

5.) Remove pressure hose.

WARNING

Skin puncture hazard.

High pressure fluid can inject under skin resulting in serious injury including amputation. Do not direct spray at people or animals.

-If skin injection happens, seek IMMEDIATE surgical treatment.

-Do not use unit if exterior hose damage is evident. Make sure all fittings are tight before starting. Relieve system pressure before servicing.

-Know how to stop engine and bleed pressures quickly. Be thoroughly familiar with the controls.

-Make sure accessories meet the unit's temperature and pressure limits. -Stop engine and bleed pressures before leaving unit unattended.
