STEP 1: Check engine oil level. Oil level should be level with the bottom of the oil fi ller 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 fi rst 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.

DETERGENT AND GENERAL CLEANING TECHNIQUES
WARNING
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.
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.
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).

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.
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 fi lter end of detergent suction tube into detergent container.
STEP 3: With safety latch on spray gun engaged, secure black detergent nozzle into quick coupler. NOTE:
Detergent cannot be applied using red, 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.
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.
IMPORTANT: You must fl ush 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.
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 fl owing 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.

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.
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.
4. Cover pressure washer and store in a clean, dry place that is well ventilated away from open fl ame 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.
5. Do not allow high pressure hose to become kinked.
After Extended Storage
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.
CAUTION: Prior to restarting, thaw out any possible ice from pressure washer hoses, spray gun or wand.
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
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 defl ecting 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.
