MAINTENANCE WARNING: Before inspecting, cleaning or servicing the machine, shut off motor, wait for all moving parts to stop, disconnect unit from power supply, and pull trigger to release water pressure. 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 identical replacement parts. Use of any other parts could create a hazard or cause product damage. 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, 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. PUMP LUBRICATION The pump on this unit is 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. POWER SUPPLY CORD REPLACEMENT If replacement of the power supply cord is necessary, this must be done by an authorized service center in order to avoid a safety hazard. 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 Unplug the pressure washer. 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 motor, 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 Using a straightened paper clip or nozzle cleaning tool (not provided), 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. 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 an authorized 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. 14 - English
