Wing Nut Air Filter Housing Foam Air Filter Paper Air Filter 1. 2. 3. 4. 5. 6. Loosen the nut and remove the air filter cover. Remove the air filter housing and elements and inspect for cleanliness. Gently shake the paper filter or blow with air to remove the dust and debris. Clean the foam air filter with soap and water or solvent and let dry. Soak the foam filter in clean engine oil. Gently squeeze and then pat out all excess oil and reinstall. If excess oil remains in the foam filter it can seep through to the paper filter and damage it. Replace either filter if it is damaged. Note Never run the pressure washer without an air filter, doing so will quickly degrade the engine. 29 6.5 NOZZLE CLEANING 1. Detach the quick connect nozzle from the wand. Use the included nozzle cleaning tool or a paper clip to loosen up any stuck particles in the nozzle. Flush with water. 6.6 CLEANING WATER INLET FILTER Check the water inlet filter periodically and clean if necessary. 6.7 SPARK PLUG SERVICE Note Do not rinse spark plug in water. Follow guidelines and be careful not to overtighten the spark plug. Recommended spark plug: F7TC Check the spark plug gap and clean the carbon deposits at the bottom of the spark plug. Tighten 1/2 turn when installing a new spark plug. Tighten 1/8 TO 1/4 turn when re-installing an old spark plug. 0.70-0.80mm (0.028-0.031in) 30 RWSERIES 1. 2. 3. 4. 5. 6. Remove the spark plug cap. Remove the spark plug with the spark plug wrench. Visually inspect the spark plug. Replace with a new plug if the insulation is cracked or chipped. Clean with a wire brush if the spark plug is reused. Measure the spark plug gap with a feeler gauge. The normal value is: 0.7-0.8mm (0.028- 0.031in). Adjust the gap by carefully bending the electrode. Carefully reinstall the spark plug by hand, to avoid cross-threading. A new spark plug should be tightened 1/2 turn with a spanner. A used spark plug should be tightened 1/8 to 1/4 turn with spanner. Reinstall the spark plug cap. Note The spark plug must be securely tightened or it could cause the spark plug to heat up, enough to damage the engine. Never use a spark plug with an improper heat range. 6.8 SPARK ARRESTER MAINTENANCE Spark Arrester 1. 2. 3. After the engine has cooled down remove the spark arrester from the muffler. Use a brush to remove carbon deposits from the spark arrester. If the spark arrester is worn down, replace it.

It is very important to control the emissions of NOx and hydrocarbons as they are a major contributor to air pollution. Carbon monoxide is a poisonous gas. The emission of fuel vapors is a source of pollution as well. The pressure washer engine utilizes a precise air-fuel ratio and emission control system to reduce the emissions of carbon monoxide, NOx, hydrocarbons and evaporative fuel emissions. Regulation Your engine has been designed to meet current Environmental Protection Agency (EPA) clean air standards. The regulations dictate that the manufacturer provides operation and maintenance standards regarding the emission control systems. Tune up specifications are provided in the Specifications section and a description of the emission control system may be found in the appendix to this manual. Adherence to the following instruction will ensure your engine meets the emission control standards. Modification Modification of the emission control system may lead to increased emissions. Modification is defined as the following: Disassembling or modifying the function or parts of the intake, fuel or exhaust system. Modifying or destroying the speed governing function of the pressure washer. 32 RWSERIES Engine faults that may affect emission Any of the following faults must be repaired immediately. Consult with your authorized service centre for diagnosis and repair: Hard starting or shut down after starting. Unstable idle speed. Shut down or backfire after applying an electrical load. Backfire or after fire. Black smoke and/or excessive fuel consumption. Replacement parts and accessories The parts making up the emission control system in your product’s engine have been specifically approved and certified by the regulatory agencies. You can trust that the replacement parts supplied by customer service have been manufactured to the same production standard as the original parts. The use of replacement parts or accessories which are not designed for your engine – may negatively affect the engine emission performance. Therefore only use replacements parts and accessories from a qualified service centre to guarantee that the replacement products will not adversely affect emission performance. Replacement parts other than those from an authorized service centre will void the warranty. 33 7. TRANSPORTATION & STORAGE 7.1 TRANSPORTING THE PRESSURE WASHER Do not overfill the fuel tank (No residual fuel on the neck of tank). Avoid exposing the pressure washer to prolonged direct sunlight while Storage Duration Preparation Required Less than 1 Month No storage preparation required, simply store as is. 1 Month to 1 Year Drain the old gas and completely fill the tank with fresh gas before storage. Add fuel stabilizer according to the manufacturer’s directions. Run the engine outdoors for 5-10 minutes to ensure the stabilized gas has replaced the untreated gas in the carburetor. Adding a quality fuel stabilizer can keep gas fresh for up to a year. Drain off the gasoline from the fuel tank, and store in a suitable container. This will help prevent deposits from forming in the fuel system. 1 Year or More Turn the fuel switch to OPEN and loosen the carburetor drain bolt. Take off the spark plug cap and revolve the engine 3 or 4 times, by pulling the recoil handle, to fully discharge the gasoline from the fuel lines. Turn the fuel switch to CLOSED and tighten the drain bolt of the carburetor. Change oil while engine is still warm from operation. Remove the spark plug, and pour a tablespoon of clean engine oil (10~20ml) into the cylinder. Revolve the engine several times by pulling on the recoil start to distribute the oil. Reinstall the spark plug. Pull the starter grip slowly until you feel resistance. At this point, the piston is coming up on its compression stroke and both the intake and exhaust valves are closed. This position helps to protect the engine from internal corrosion. 34 RWSERIES in an enclosed vehicle. The high temperature inside the vehicle could cause fuel to vaporize resulting in a possible explosion. Drain the pressure washer of fuel and oil before being transported on rough roads. 7.2 DRAINING THE FUEL TANK 1. 2. Turn OFF the engine. Remove the fuel cap and the debris screen underneath the fuel cap. Empty the fuel tank using a siphon and an approved gasoline container. 7.3 DRAINING THE CARBURETOR Carburetor Drain Screw Container 1. 2. 3. 4. Turn OFF the engine and allow it to cool. Turn the fuel valve to OPEN. Position a container under the carburetor drain screw. Loosen the drain screw. Allow fuel to completely drain and re-tighten the drain screw. Turn the fuel valve to CLOSED. 35 7.4 LONG TERM STORAGE - ENGINE Before storing the pressure washer set for an extended period: Ensure that the storage area is free of excess humidity and dust. Drain the fuel tank and the carburetor. 7.5 LONG TERM STORAGE - PUMP When storing your unit for more than 30 days pressure washer pump guard (pump saver or pump winterizer) is recommended to keep seals lubricated, protect from rust, and prevent the pump from freezing damage. Note DO NOT let water in the pump freeze. It will cause irreversible damage to the pump. Pump guard application may require two people. 1. 2. 3. 4. 5. Turn off pressure washer and disconnect all hoses. Connect the pump saver to the water supply inlet. Depress the button on top of the pump saver container. With the ignition off, pull the starter rope and squeeze the bottle. Repeat until pump guard fluid exits the high pressure hose outlet. This may require two people. Remove the hose from the water supply inlet. 7.6 LONG TERM STORAGE - HOSES 1. 2. 3. Drain all water from the high pressure hose and wrap it onto the holder. Drain all water from the spray gun by holding it vertically with the nozzle down and squeezing the trigger until the water stops flowing. Ensure the detergent siphon hose is drained and wrap it up securely. 36 RWSERIES 8.
