GNW2820A GAS PRESSURE WASHER

 NOTICE ： When the environment temperature is higher such as summer, or engine is in a hot state, choke valve should be switched to "ON" or intermediate position, then start the engine.

7.2 INSTRUCTIONS FOR USE

➢

Cleaning operation

Position the tip of the wand 6-8” (15-20 cm) away from the surface to clean at a

45°angle.

➢

Nozzles

This pressure washer comes with 5 different pattern of nozzles.

RED 0° ： Thin and powerful stream of water for difficult stains and debris removal.

YELLOW 15° ： Thin angled spray for focused cleaning.

GREEN 25° ： Medium angled spray for focused cleaning.

WHITE 40° ： Large fan pattern for wider cleaning applications.

BLACK detergent ： This nozzle must be used in conjunction with a cleaning detergent at low pressure. Only use this nozzle when using a detergent or cleaning solution.

➢

ADJUSTING WATER PRESSURE

This engine comes with a throttle lever. The pressure can be adjusted by changing the speed of engine.

Turning the throttle lever to the left can increase the speed to get more pressure.

GNW2820A GAS PRESSURE WASHER

Turning the throttle lever to the right can decrease the speed to get less pressure.

WARNING!

When moving the engine throttle to the minimum (rightmost), the output power of engine is low. Please don’t operate the machine, if not, the machine will be flameout stop due to low engine output power.

➢

DETERGENT INJECTOR (LOW

PRESSURE)

This pressure equips a detergent bottle. Pure detergent into the bottle, and fit black nozzle on the wand, then squeeze the trigger. The detergent will be mixed with water and sprayed out. It will achieve a better cleaning effect.

GNW2820A GAS PRESSURE WASHER

WARNING!

Some cleaning jobs can be completed by using only water, but for most, it is advantageous to use a detergent to penetrate and remove the dirt more effectively. When using pressure washer approved detergent, make sure the surface to clean is dry. Wetting the surface first is not recommended; it will dilute the detergent and will reduce the cleaning effectiveness.

Avoid hot surfaces or direct sunlight; this will minimize the chances of the detergent damaging the painted surface.

DO NOT let the detergent dry or it may damage the painted surface.

Allow the detergent to remain on the surface for a short time before rinsing with clean water under high pressure.

➢

Shut down the pressure washer

Step #1 ： Turn the engine switch into “OFF” position to shut down the engine.

Step #2 ： Turn the fuel valve into “OFF” position to cut off the fuel..

Step #3 ： Squeeze the trigger of spray gun, release the pressure inside the pump.

Step #4 ： Cut off the water supply.

Step #5 ： Squeeze the trigger again to drain the rest water of system.

Step #6 ： Disconnect the pressure hose and spray gun.

Step #7 ： Put the gun and hose on the hook.

All done!

WARNING!

This pressure washer is intended for use with pressure washer detergents only.

Do not use powdered soaps which will clog the injection system.

Follow the detergent manufacturer’s directions.

9, MAINTENANCE

9.1 WATER INLET FILTER:

This pressure washer is equipped with a water inlet filter.

This water filter must be kept clean at all times or else it will restrict the water flow to the pressure washer and may damage the pump.

Remove the quick connect coupling from the water inlet, then remove and clean water filter.

DO NOT operate this pressure washer without the water inlet filter in place as deposits could build up internally and affect the functioning of the unit.

9.2 ENGINE MAINTAINENCE:

Engine oil should be replaced after the first 5 hours of operation.

It should be replaced every 100 hours or every year.

To replace engine oil: loosen the oil gauge dipstick. Place an oil pan underneath drain hex screw, remove hex screw and drain oil. Once all the oil has completely drained, retighten the hex screw.

HES

SCREW

***It is recommended to use SAE10W-30 4-stroke gasoline engine oil.

***Fill with clean engine oil through the oil gauge dipstick hole to recommended level.

GNW2820A GAS PRESSURE WASHER

9.3 CLEANING CARBURETOR

1) Screw down the bolt on the bottom of carburetor with wrench.

2) Push the float up four to five times, then clean sediment cup with gas.

3) Put the sediment cup back.

*** Be careful not to miss the O ring.

9.4 INSPECTING SPARK PLUG

The spark plug should be checked every 100 hours of operation or every year.

9.5 REPLACING AND CLEANNING SPARK PLUG

1) Dismantle the spark plug wire by pulling it off the spark plug. Using the supplied spark plug wrench, undo the spark plug by turning counter clockwise.

2) Check to see if there is carbon sediment buildup, if so, remove it. If the carbon sediment is excessive, replace the spark plug.

3) Measure the electrodes clearance using a feeler gauge. The spark plug electrode clearance should be 0.7-0.8 mm. If the clearance exceeds 0.8 mm, replace the spark plug.

4) Reinstall spark plug in the reverse order.

10.1 FUEL STABILIZER

1) Add fuel stabilizer to fuel tank to minimize the formation of fuel gum deposits during storage.

2) Run engine at least 5 minutes after

FUEL STABILIZER adding stabilizer to allow it to enter the fuel system.

FUEL TANK

NOTE: If a fuel stabilizer is not used, all gasoline must be drained from the tank and carburetor to prevent gum deposits from forming on these parts and causing possible malfunction of the engine.

10.2 DRAINING FUEL

1) Turn fuel valve to the “OFF” position, remove drain hex screw from the carburetor.

2) Now turn fuel valve to the “ON” position and drain the fuel from the tank, carburetor and hose.

3) Reposition the carburetor drain hex screw once the fuel is completely drained.

2) Cover the pressure washer and store it in a clean, well ventilated and dry place. Ensure storage area is at room temperature.

3) In addition, in order to prevent external parts rust, please daub anti-rust oil to bolts and nuts of machine at least every one year.

10.5 PUMP ANTIFREEZE

If your pressure washer is subjected to freezing temperatures, damage could occur. This type of damage is not covered under warranty. To avoid possible damage, a small amount of antifreeze can be used.

1) Place the unit on its side with the water inlet facing upwards, pour 1/4 cup of antifreeze into the water inlet.

2) Disconnect spark plug wire, and then pull recoil starter several times to circulate the antifreeze in the pump system. Reconnect spark plug wire.

3) It is also important to make sure the wand and all hoses are disconnected and drained of all water or they may burst.

When taking pressure washer out of storage, run water through the system until it runs clear.
