• Damage to equipment resulting from failure to follow this instruction will void warranty.

You must attach all hoses before you start the engine.

CAUTION

• Always make sure the surface you will clean will not be damaged by the high pressure spray by testing in a hidden area.

The turbo nozzle produces an extremely high pressure spray which is capable of removing paint and cutting holes through surfaces if held too close.

To apply detergent, follow these steps:

1. Review use of adjustable nozzle.

2. Prepare detergent solution as required by job.

3. Place filter end of detergent siphoning tube into detergent container.

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 from bottom and working up.

7. Allow detergent to “soak in” for 3-5 minutes before rinsing. Reapply as needed to prevent surface from drying.

8. For washing, start at lower portion of area to be washed and work upward, using long, even, overlapping strokes.

IMPORTANT: You must flush the chemical injection system after each use by placing the filter into a clean bucket of water and running the pressure washer in low pressure for 1-2 minutes.

Pressure Washer Rinsing

For Rinsing:

1. Slide nozzle backward to high pressure, press trigger and wait for detergent to clear.

NOTE: You can also stop detergent flow by removing detergent siphoning tube from container.

2. Keep spray gun a safe distance from area you plan to spray.

Keep the chemical injection tube from coming in contact with the hot muffler.

ENGINE TECHNICAL INFORMATION

This is a single cylinder, L-head, air cooled engine. It is a low emissions engine.

In the State of California, Model Series 90000 engines are certified by the California Air Resources Board to meet emissions standards for 125 hours. Such certification does not grant the purchaser, owner or operator of this engine any additional warranties with respect to the performance or operational life of this engine. The engine is warranted solely according to the product and emissions warranties stated elsewhere in this manual.

Power Ratings

The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002-

05). Given both the wide array of products on which our engines are placed, and the variety of environmental issues applicable to operating the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a piece of power equipment (actual “on-site” power). This difference is due to a variety of factors including, but not limited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, maximum governed engine speed, individual engine to engine variability, design of the particular piece of power equipment, the manner in which the engine is operated, engine run-in to reduce friction and clean out of combustion chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match the values derived using the foregoing codes.

Pressure washer parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris.

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt, oil, etc.

• Use a vacuum cleaner to pick up loose dirt and debris.

• Use low pressure air (not to exceed 25 psi) to blow away dirt. Inspect cooling air slots and openings on the pressure washer. These openings must be kept clean and unobstructed.

Check and Clean Inlet Screen

Examine garden hose inlet screen. Clean if it is clogged or replace if it is torn.

Check High Pressure Hose

High pressure hoses can develop leaks from wear, kinking, or abuse. Inspect hose before each use. Check for cuts, leaks, abrasions, bulging of cover, or damage or movement of couplings. If any of these conditions exist, replace hose immediately.

Check Gun and Nozzle Extension

Examine hose connection to gun and make sure it is secure. Test trigger by pressing it and making sure it springs back into place when you release it. Engage safety latch and test trigger. You should not be able to press trigger. Replace gun immediately if it fails any of these tests.

Check In-Line Filter

Refer to the illustration and service the in-line filter if it becomes clogged, as follows:

1. Detach nozzle extension from gun and remove o-ring and screen from nozzle extension. Flush screen, gun, and nozzle extension with clean water to clear debris.

2. Place in-line filter screen into threaded end of nozzle extension. Direction does not matter. Push screen in with eraser end of pencil until it rests flat at bottom of opening. Take care not to bend screen.

3. Place o-ring into recess. Push o-ring snugly against in-line filter screen.

4. Assemble nozzle extension to spray gun, as described earlier in manual.

Nozzle Maintenance

A pulsing sensation felt while squeezing the spray gun trigger may be caused by excessive pump pressure. The principal cause of excessive pump pressure is a nozzle clogged or restricted with foreign materials, such as dirt, etc. To correct the problem, immediately clean the nozzle following these instructions:

1. Shut off engine and turn off water supply.

2. Remove nozzle from end of nozzle extension. Separate nozzle extension from spray gun. Twist nozzle clockwise to stream position. Using a 2mm (5/64) allen wrench, remove orifice from end of nozzle extension.

3. Remove in-line filter from other end of nozzle extension.

4. Use a small paper clip to free any foreign material clogging or restricting orifice.

5. Using a garden hose, remove additional debris by back flushing water through nozzle extension. Back flush between 30 to 60 seconds. Turn adjustable nozzle extension to stream spray and move nozzle from low to high while flushing.

6. Reinstall orifice and in-line filter into nozzle extension. DO NOT overtighten orifice with allen wrench.

7. Reconnect nozzle extension to spray gun.

8. Reconnect water supply, turn on water, and start engine.

9. Test pressure washer by operating nozzle in high and low positions.
