General Operating Instructions

1.Point the Nozzle in a safe direction and squeeze the trigger to check that all pressure is released from the unit. Release the Trigger.

2.Turn on the water supply, then turn on the Power Switch.

Note: If the unit does not turn on or turns off suddenly, check and reset the GFCI.

3.Unlock and squeeze the Trigger to start the stream. Be aware that when it is first started, the gun will kick back.

4.Test spray the edge of the surface to be cleaned to make sure that the stream is not too strong for the surface. Adjust the pressure by squeezing the Trigger more or less, and by changing your distance from the surface. Adjust the stream from a fan to a direct stream by turning the nozzle.

5.When finished using the Pressure Washer, release the Trigger, turn the Power Switch off, unplug the unit, and turn off the water supply.

6.Point the Nozzle in a safe direction and squeeze the trigger to check that all pressure is released from the unit. Release and lock the Trigger.

7.Clean, then store indoors, out of children’s reach.

Operating Tips

Become Familiar With your Machine:

1.Before beginning work, set aside enough time to familiarize yourself with this machine’s cleaning rate and capacity along with all instructions and precautions contained in this section, along with the Operating Instruction and Controls and Features sections.

2.This unit is intended for various light to moderate cleaning applications. If deeper cleaning is desired, it can be attained at times, however this is done at the expense of speed. This unit is not intended for paint stripping or deep concrete cleaning applications.

3.Clean a test area to satisfaction before proceeding with the entire area, as stated in Cleaning Recommendations.

4.This unit has several settings and adjustments that effect the speed of cleaning and the water force applied to cleaning. Good guidelines to keep in mind are:

Wide Stream =

Quicker Coverage but

Lighter Cleaning.

Narrow Stream =

Deeper Cleaning but

Slower Coverage.

Use Proper Pressure Washer Operation Techniques:

The machine may suddenly stop and require a rest period from time to time; this is normal and does not indicate a problem (See Troubleshooting Section). However, certain operating techniques may help reduce or even prevent the need for such rest periods, increasing efficiency:

a.Do not release the trigger between sweeps. Release the trigger as few times as possible during use. Interrupted or sporadic spraying will cause the unit to heat up quickly and will increase the need for rest periods.

b.Make sure that all obstacles have been moved and the entire area is ready before starting.

c.For small jobs, try to finish an entire portion of the job before taking a break.

Cleaning Recommendations

5.Clean an inconspicuous test area first. Always begin with the fan spray at a distance of about 3-5 feet from the surface being cleaned to avoid damaging it. Clear the test area of people and water-sensitive objects.

If a pressure washing detergent is to be used, apply the detergent to this area as well. After cleaning this area, switch off the pressure washer and inspect the area carefully for any damage or discoloration. If any damage is noted from the pressure setting, use a lighter setting when cleaning the rest of the area. If damage or discoloration is noted from

the detergent, do not use it when cleaning.

6.First, pass over the area with a light cleaning, and then more thoroughly clean it.

For a vertical or sloped surface:

a.Wash from the top down.

b.If possible, direct the stream in the same direction as the slope towards a draining area. This will enable better drainage and therefore better cleaning.

For a flat surface:

a.If a thin layer of water accumulates on the surface, periodically use the stream to direct this water towards the drainage.

b.After the major cleaning is done, sweep the surface with the stream to help direct loose debris toward the drainage.

7.If detergent is to be applied: Only use pressure washing detergent in the soap dispenser; other detergents will clog the dispenser. Do not add detergent to the body of the pressure washer. Spray the surface with detergent until evenly covered, then turn off the machine and water source, release pressure, and remove the soap dispenser. Allow the detergent several minutes to sit and soak into the work surface; this will improve
