MAINTENANCE GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which could result in serious personal injury. Before running the engine, perform the following preoperation steps: n Check that all bolts, nuts, etc., are securely tightened. n Make sure the air filter is clean. n Check both the engine oil level and the fuel tank level; refill as needed. n Inspect the work area for hazards. n If there is excessive noise or vibration, stop the unit im- mediately. NOZZLE MAINTENANCE See Figure 18. Excessive pump pressure (a pulsing sensation felt while squeezing the trigger) may be the result of a clogged or dirty nozzle. n Turn off the pressure washer and shut off the water supply. Pull trigger to release water pressure. n Remove the nozzle from the spray wand. WARNING: NEVER remove nozzles without first turning off the engine, relieving the water pressure in the trigger handle, and locking the lock out on the trigger handle. NEVER point the nozzle at your face or at others. The quick-connect feature contains small springs that could eject the nozzle with some force. Failure to follow these instructions could result in an eye injury or other serious personal injury. n To free any foreign materials clogging or restricting the nozzle, blow out or remove debris with a straightened paper clip or fine needle. n Using a garden hose, flush debris out of nozzle by back flushing (running the water through the nozzle backwards or from the outside to the inside). n Reconnect the nozzle to the spray wand. n Turn on the water supply and start the engine. STORING THE PRESSURE WASHER See Figure 19. NOTE: Regular use of fuel stabilizer and pump protector will give you better performance of the unit and increase the life of the pump. See the Replacement Parts List for available sizes and part numbers of these items and call customer service to order. 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 detergent bucket 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 engine switch is in the OFF position and and fuel valve is in the CLOSED position. n Disconnect both the high pressure and low pressure water connections. 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: The use of a pump protector is required after each use and before storing to prevent cold weather and seal damage during storage. Failure to use pump protector will void your warranty. n Drain the lubricant and replace with fresh, clean lubricant as described in the engine manual. n Disconnect spark plug wire and remove the spark plug. Pour about a teaspoon of clean, air-cooled, four-cycle oil through the spark plug hole into the combustion chamber. n Leaving the spark plug out, pull the starter grip and rope two or three times to coat the inside of the cylinder wall. n Inspect the spark plug and clean or replace, as necessary. n Reinstall the spark plug, but leave the spark plug wire disconnected.
