Operating Instructions

Read and understand the entire manual before operating the pressure washer.

Follow these instructions every time you use the pressure washer.

I.) Pre-Operation

;A.) Position the machine for easy access to all controls.

;B.) Position the machine on a solid surface, with less than a three degree slope, and so it is protected from external damage.

;C.) Make sure ambient lighting is sufficient for the surface you are cleaning to be seen with ease. Use artificial light if needed.

;D.) Check hoses, fittings, wand, trigger gun and electrical cords for signs of wear, cracks and looseness, and replace as required.

;E.) Check and clean the nozzle orifice.

;F.) Check and clean the water inlet screen and filter.

;G.) Read entire manual, especially the important safety instructions listed on page 2.

;H.) Check and maintain proper oil levels in the pump.

II.) Check Your Water Supply

;A.) Make sure the water supply is clean. Debris can cause excess pump wear and reduce performance.

;B.) 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.

Example: If the rated flow is = 3gpm

Then required flow = 3 x 1.20 = 3.6gpm 5gallons / 3.6gpm = 1.39 minutes 1.39min x 60sec/min = 83 seconds Therefore, you must be able to fill a

5 gallon bucket in 83 seconds or faster.

;C.) 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”.

;D.) Never use a reservoir tank as a water source. This pressure washer is designed for a pressurized water source such as a city water faucet. Sucking water out of a tank may cause pump cavitation and damage to your pump. However, the inlet pressure of the pump must not exceed 115 psi (8 bar).

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

;F.) Do not pump flammable liquids or liquids containing incompatible chemicals or solvents.

III.) Before Starting

WARNING: Check hoses, fittings, wand, gun and cords daily for signs of wear, cracks and looseness, and replace as required.

1.Connect water supply hose to the garden hose connector located on the side of the unit.

2.Connect high pressure hose to quick connect outlet on front of the machine.

3.Connect spray gun to high pressure hose.

4.If detergents will be used, only use detergents intended for pressure washers. Follow instructions on the detergent container.

IV.) To Start

DANGER: Do not point the spray wand at yourself or at any person. Bodily injury may result from water under high pressure.

WARNING: Wear eye, ear, hand, foot and skin protection at all times while operating this pressure washer. IMPORTANT: The water must be turned on before starting. Running the pump dry will cause damage and void warranty.

1.Turn water supply ON.

2.Squeeze the trigger to allow air to purge from the system. (this step goes faster with the pressure nozzle removed)
