MAINTENANCE Normal maintenance, replacement or repair of emission control devices and systems may be performed by any qualified repair establishment or individual with original or equivalent parts. Warranty and recall repairs must be performed by an authorized service center; please contact customer service for assistance. WARNING: Before inspecting, cleaning, or servicing the machine, shut off engine, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug. Allow 30 minutes of cool down time before performing any maintenance. Failure to follow these instructions can result in serious personal injury or property damage. WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. WARNING: When servicing, use only recommended or equivalent replacement parts. Use of any other parts could create a hazard or cause product damage. NOTICE: This product is not equipped with a spark arrestor and cannot be used on U.S. forest lands; in addition, product users must comply with Federal, State, and local fire prevention regulations. Check with appropriate authorities. Refer to accompanying engine manual for maintenance and replacement parts. NOTICE: Periodically inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced. Please contact customer service or a qualified service center for assistance. 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, lubricant, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating lubricants, 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 pre operation steps: n Check that all bolts, nuts, etc., are securely tightened. n Make sure the air filter is clean. n Check both the engine lubricant 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 ­immediately. NOZZLE MAINTENANCE See Figure 19. 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 quickconnect 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 Using a straightened paper clip or fine needle (not included), free any foreign materials clogging or restricting the nozzle. 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. 14 - English
