1. Slide nozzle forward when you wish to adjust

spray to low pressure mode.

2. Slide nozzle backward to achieve high pressure.

3. Point nozzle down towards a firm surface and

press trigger to test pattern.

4. Twisting nozzle adjusts spray pattern from a

narrow pattern to a fan pattern.

Usage Tips

• For most effective cleaning, keep spray nozzle

from 20 to 60 CM (8 to 24 IN) away from cleaning
surface.

• If you get spray nozzle too close, especially using

high pressure mode, you may damage surface
being cleaned.

• Do Not get closer than 15 CM (6 IN) when

cleaning tires.

Applying Detergent with

Adjustable Nozzle

IMPORTANT: Use soaps designed specifically for
pressure washers.

Household detergents could

damage the pump.

CAUTION

: You must attach all hoses before you

start the engine.
• Starting the engine without all the hoses

connected and without the water turned ON will
damage the pump.

• Damage to equipment resulting from failure to

follow this instruction will void warranty.

To apply detergent, follow these steps:

1. Review use of adjustable nozzles.
2. Prepare detergent solution as required by job.
3. Place filter end of detergent siphoning tube into

detergent container.

CAUTION

: Keep the detergent siphoning tube from

coming in contact with the hot muffler.
• When inserting the filter into a detergent solution

bottle, route the tube so as to keep it from
inadvertently contacting the hot muffler.

4. Slide adjustable nozzle forward to low pressure

mode. Detergent cannot be applied with nozzle
in high pressure position.

5. Make sure garden hose is connected to water

inlet. Check that high pressure hose is
connected to spray gun and pump. Start engine.

6. Apply detergent to a dry surface, starting at

lower portion of area to be washed and work
upward, using long, even, overlapping strokes.

7. Allow detergent to "soak in" for 3-5 minutes

before washing and rinsing. Reapply as needed
to prevent surface from drying. DO NOT allow
detergent to dry on (prevents streaking).

IMPORTANT:

You must flush the chemical injection

system after each use by placing the filter into a
bucket of clean water, then run the pressure washer
in low pressure for 1-2 minutes.

Pressure Washer Rinsing

For Rinsing:

1. Slide the nozzle backward to high pressure,

press the trigger and wait for the detergent to
clear.

NOTE

: You can also stop detergent from flowing by

simply removing detergent siphoning tube from
chemical container.
