Ryobi RY802900 Operation Manual - Page 18

MAINTENANCE  If the filter element is dirty, clean with warm, soapy water. Rinse and let dry.  Apply a light coat of engine lubricant to the element, then squeeze it out.  Replace the element in the air filter unit.  Replace the air filter cover and latch to secure. NOTE: Do not run the pressure washer without the air filter. Rapid engine wear will result. CHECKING THE SPARK PLUG See Figure 22. n Clean the area around the base of the spark plug before removing to keep dirt and debris out of the engine. Remove spark plug. n Clean off carbon deposits on the spark plug electrode using a plug cleaner or wire brush. Replace the plug if worn or reuse is questionable. For replacement spark plug, see Product Specifications earlier in this manual or the accompanying engine manual, if applicable. n Check electrode gap. The gap should be .028 in.-.032 in. (0.7- 0.8 mm). Adjust the gap, if necessary, by carefully bending the ground electrode. n Reinstall spark plug. Tighten securely. CHANGING ENGINE LUBRICANT See Figure 23. n Shut off the engine. n Clean the area around the oil fill cap/dipstick, then remove the oil fill cap/dipstick. NOTE: Remove the dipstick to allow lubricant to drain easier and more quickly. n Tilt the pressure washer on its side as shown. Drain lubricant into approved container. NOTE: Drain the lubricant while the engine is still warm but not hot. Warm lubricant will drain quickly and more completely. WARNING: Do not change engine lubricant while it is hot. Accidental contact with hot engine lubricant could result in serious burns. n After the crankcase is completely drained, return the pressure washer to an upright position. n Fill with lubricant following the instructions in Adding/ Checking Engine Lubricant earlier in this manual. For amount of lubricant needed to refill, see Product Specifications earlier in this manual or the accompanying engine manual, if applicable. n Before using the pressure washer, check to ensure that no lubricant is leaking from the engine. NOTE: Consult hazardous waste management guidelines in your area for the proper way to dispose of used lubricant. PUMP LUBRICATION The pump on this product was lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required. PUMP MAINTENANCE Routinely make a visual inspection of the pump. If you notice any leaking of lubricant around the pump seals, take the pressure washer to a qualified service center for repair. There are no user serviceable parts to the pressure washer pump. Any attempt to service or alter the pump may damage the pressure washer and void your product warranty. STORING THE PRESSURE WASHER See Figure 24. NOTE: Regular use of fuel stabilizer and pump protector will give you better performance of the unit and increase the life of the pump. WARNING: While storing, keep at least 3 feet of clearance on all sides of this product, including overhead. Allow a minimum of 30 minutes of "cool down" time before storage. Heat created by muffler and exhaust gases could be hot enough to ignite combustible objects. Store in a dry, covered area where the weather can't damage it. It is important to store this product in a frost-free area. Always empty water from all hoses and the pump before storing. n Drain the fuel tank completely by running the pressure washer until the gas runs out. Stored gas can go stale in 30 days. NOTE: Make sure the water supply is connected and turned on when allowing the pressure washer engine to run. n Make sure the fuel valve is in the CLOSED position. n Disconnect both the high pressure hose and the garden hose from the pump. n Empty the pump by pulling on the starter grip and rope about 6 times. This should remove most of the liquid from the pump. NOTICE: If the location where your pressure washer is stored will fall below 32°F, the use of a pump protector is required before storing to prevent freeze damage. Freeze damage will void your warranty. Page 14 - English
