STEP 9: To reduce the possibility of sparking attach the wires to the battery in the following order.Refere to image aside. First attach the red wire to the positive “+” terminal of battery and the black wire to the negative “-” terminal of the battery.To disconnect the battery remove the wires in the opposite order as installed. Install battery box cover and fasten in place.

OPERATING INSTRUCTIONS

STEP 1: Check engine oil level. Oil level should be level with the bottom of the oil filler neck. Be sure the machine is level when checking the oil level. (Refer to the engine’s operating manual included with machine.) We recommend that the oil be changed after the first 5 hours of use, then once every 50 hours. Note: Improper oil levels will cause low oil sensor to shut off engine. IMPORTANT! Do not run engine with high or low oil levels as this will cause engine damage.

STEP 2: Remove shipping cap and install oil dipstick. Check pump oil level by using dipstick or observe oil level in oil window (if equipped). Use 40 wt. non detergent oil.

STEP 3: Fill gas tank with unleaded  asoline. Do not use leaded gasoline.

STEP 4: Connect garden hose to the cold water source and turn water on completely. Never use hot water.

STEP 5: Trigger the spray gun to eliminate trapped air then wait for a steady flow of water to emerge from the spray nozzle.

STEP 6: Slide the fuel valve lever to the “ON” position. When the engine is not in use, leave the fuel valve in the “OFF” position.

STEP 7: Move the choke lever to the “Choke” position (on a warm engine, leave the choke lever in the run position).

STEP 8: Turn the engine switch to “On” position.

STEP 9: Pull the starter grip. If the engine fails to start after 2 pulls, squeeze the trigger gun to release pressure and repeat step. Return starter gently. After the engine warms up enough to run smoothly, move choke to run position and throttle to fast position.

CAUTION: Small engines may kick back. Do not hold pull starter grip tightly in hand.
WARNING! Never replace nozzles without engaging the safety latch on the spray gun trigger.

NOZZLES

The four color-coded quick connect nozzles provide a wide array of spray widths from 15° to 40° and are easily accessible when placed in the convenient rubber nozzle holder, which is provided on the front of the machine.
NOTE: For a more gentle rinse, select the white 40° or green 25° nozzle. To scour the surface, select the yellow 15° nozzle. To apply detergent select the black nozzle.

DETERGENT AND GENERAL CLEANING TECHNIQUES

WARNING: Some detergents may be harmful if inhaled or ingested, causing severe nausea, fainting or poisoning. The harmful elements may cause property damage or severe injury.

STEP 1: Connect the optional detergent injector to discharge nipple on machine. Connect high pressure hose to injector with quick coupler. (Check to make sure locking coupler sleeves are in proper position before applying water pressure).

STEP 2: Use detergent designed specifically for pressure washers. Household detergents could damage the pump. Prepare detergent solution as required by manufacturer. Fill a container with pressure washer detergent. Place filter end of detergent suction tube into detergent container.

STEP 3: With safety latch on spray gun engaged, se- cure black detergent nozzle into quick coupler. NOTE: Detergent cannot be applied using yellow, green or white nozzles.

STEP 4: With the engine running, pull trigger to operate machine. Liquid detergent is drawn into the machine and mixed with water. Apply detergent to work area. Do not allow detergent to dry on surface.
IMPORTANT: You must flush the detergent injection system after each use by placing the suction tube into a bucket of clean water, then run the pressure washer in low pressure for 1-2 minutes.
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 al- low 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

STEP 1: Remove detergent suction tube from container and insert into one gallon of fresh water. Slide nozzle forward for low pressure or to connect black detergent nozzle. Pull trigger on spray gun and siphon water for one minute.

STEP 2: Turn off the engine.

STEP 3: Turn off water supply.

STEP 4: Press trigger to release water pressure.

STEP 5: Disconnect the garden hose from the water inlet on the machine.

STEP 6: Disconnect the high pressure hose from discharge nipple.

STEP 7: Engage the spray gun safety lock.

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 re- maining 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.

After Extended Storage
CAUTION: Prior to restarting, thaw out any possible ice from pressure washer hoses, spray gun or wand.
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.
