MAINTENANCE CHANGING ENGINE LUBRICANT See Figure 25. n Shut off the engine. n Clean the area around the oil cap/dipstick, then remove the oil cap/dipstick. NOTE: Remove the dipstick to allow lubricant to drain easier and more quickly. n Disconnect the spark plug wire from the engine. n To drain the lubricant, remove the drain plug from the bottom of the engine. Drain lubricant into an approved container, then reinstall drain plug and tighten securely. 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 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. CHECKING SPARK PLUG See Figure 26. 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 0.7 - 0.8 mm. Adjust the gap, if necessary, by carefully bending the ground electrode. n Check the condition of the spark plug gasket. n Reinstall spark plug. Start the spark plug in its threads by hand and finger-tighten. n Tighten with wrench to compress washer. If spark plug is new, use 1/2 turn to compress washer appropriate amount. If reusing old spark plug, use 1/8 to 1/4 turn for proper washer compression. NOTE: An improperly tightened spark plug will become very hot and could damage the engine. 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 27. 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, the pump, and the soap tank 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 on/off switch is OFF and fuel valve is CLOSED. 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. n Drain the lubricant and replace with fresh, clean lubricant as described in Adding/Checking Engine Lubricant in the Operation section of this manual. 15 - English
