Operation of this equipment may create sparks that can start fires around dry vegetation. A spark arrestor may be required. The operator should contact: Local fire agencies for laws or regulations relating to fire prevention requirements.

7. Allow engine to cool for 1-2 minutes before refueling. If any fuel is spilled, make sure the area is dry before testing the spark plug or starting the engine. (Fire and/or explosion may occur if this is not done.)

Gasoline engines on mobile or portable equipment shall be refueled:

a. outdoors;
b. with the engine on the equipment stopped;
c. with no source of ignition within 10 feet of the dispensing point; and
d. with an allowance made for expansion of the fuel should the equipment be exposed to a higher ambient temperature.

In an overfilling situation, additional precautions are necessary to ensure that the situation is handled in a safe manner.

8. When in use , do not place machine near flammable objects as the engine is hot.
9. Do not store or use gasoline near this machine.

12. Never make adjustments on machine while in operation.
13. Be certain all quick coupler fittings are secured before using pressure washer.

15. Inlet water must be clean fresh water and no hotter then 90°F.

20. Never run pump dry or leave spray gun closed longer than 1-2 minutes.
21. Machines with shut-off spray gun should not be operated with the spray gun in the off position for extensive periods of time as this may cause damage to the pump.
22. Protect discharge hose from vehicle traffic and sharp objects. Inspect condition of high pressure hose before using or bodily injury may result.
23. Before disconnecting discharge hose from water outlet. Open the spray gun to relieve pressure.
24. Do not overreach or stand on unstable support. Keep good footing and balance at all times.
25. Do not operate this machine when fatigued or under the influence of alcohol, prescription medications, or drugs.

26.WARNING: Wear eye, hand and skin protection when handling or connecting battery.

Batteries generate explosive gases during normal battery operation.

DO NOT expose the battery to flame or sparks as these gases may ignite.

Battery fluid is highly acidic. If battery fluid con tacts skin or clothing, wash immediately with soap and water. If battery fluid enters eye, immediately flood eye with running cold water for at least 15 minutes and get immediate medical attention.

COMPONENT IDENTIFICATION

Pump — Develops high pressure.
Starter Grip — Used for starting the engine manually.
Spray Gun — Controls the application of water and
detergent onto cleaning surface with trigger device. Includes safety latch.
Unloader valve — Safety device which allows pressure
tube released when spray gun is closed
Detergent Injector — Allows you to siphon and mix detergents. (Not included with machine)
Wand — Must be connected to the spray gun.

High Pressure Hose — Connect one end to water pump discharge nipple and the other end to spray gun.
Pump Protector — Cycles fresh cool water through pump when recirculating water reaches 140°F.
Note: If trigger on spray gun is released for more than 1-2 minutes, water will leak from valve. Warm water will discharge from pump protector onto foor. This system prevents internal pump damage.

ASSEMBLY INSTRUCTIONS

OPERATING INSTRUCTIONS

DETERGENT AND GENERAL CLEANING TECHNIQUES

THERMAL PUMP PROTECTION

If you run the engine on your pressure washer for 1-2 minutes without pressing the trigger on the spray gun, circulating water in the pump can reach high temperatures. When the water reaches this temperature, the pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal device prevents internal damage to the pump.

CLEANING TIPS

Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and apply to surface at low pressure (for best results, limit your work area to sections approximately 6 feet square and always apply detergent from bottom to top). Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to be drying, simply wet down surface with fresh water. If needed, use brush to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 1 foot from cleaning surface. Use overlapping strokes as you clean and rinse any surface. For best surface cleaning action spray at a slight angle.

Recommendations:

• Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface.
• Keep the spray nozzle a safe distance from the surface you plan to clean. High pressure wash a small area, then check the surface for damage. If no damage is found, continue to pressure washing.

CAUTION – Never use:

• Bleach, chlorine products and other corrosive chemicals
• Liquids containing solvents (i.e., paint thinner, gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products

These chemicals will harm the machine and will damage the surface being cleaned.

RINSING

It will take a few seconds for the detergent to clear. Apply safety latch to spray gun. Remove black soap nozzle from the quick coupler. Select and install the desired high pressure nozzle. NOTE: You can also stop detergent from flowing by simply removing detergent siphon tube from bottle.

SHUTTING DOWN AND CLEAN-UP

STORAGE

CAUTION: Always store your pressure washer in a location where the temperature will not fall below 32°F (0°C). The pump in this machine is susceptible to permanent damage if frozen. FREEZE DAMAGE IS NOT COVERED BY WARRANTY.

1. Stop the pressure washer, squeeze spray gun trigger to release pressure.
2. Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until remaining water exits. Turn engine off immediately.
4. Drain the gas and oil from the engine.
5. Do not allow high pressure hose to become kinked.
6. Store the machine and accessories in a room which does not reach freezing temperatures.

CAUTION: Failure to follow the above directions will result in damage to your pressure washer.
When the pressure washer is not being operated or is being stored for more than one month, follow these instructions:

1. Replenish engine oil to upper level.
2.  Drain gasoline from fuel tank, fuel line, fuel valve and carburetor.
3. Pour about one teaspoon of engine oil through the spark plug hole, pull the starter grip several times and replace the plug. Then pull the starter grip slowly until you feel increased pressure which indicates the piston is on its compression stroke and leave it in that position. This closes both the intake and exhaust valves to prevent rusting of cylinder.
4. Cover pressure washer and store in a clean, dry place that is well ventilated away from open flame or sparks. NOTE: The use of a fuel additive, such as STA-BIL®, or an equivalent, will minimize the formulation of fuel deposits during shortage. Such additives may be added to the gasoline in the fuel tank of the engine, or to gasoline in a storage container.

Engine Maintenance
During the winter months, rare atmospheric conditions may develop which will cause an icing condition in the carburetor. If this develops, the engine may run rough, lose power and may stall. This temporary condition can be overcome by deflecting some of the hot air from the engine over the carburetor area. NOTE: Refer to the engine manufacturer’s manual for service and maintenance of the engine.
