Ryobi RY31012 Operation Manual - Page 2

WARNING: Do not use the surface cleaner on raised obstacles. Striking any raised obstacle while using the surface cleaner could damage the unit. If contact does occur and results in damage or vibration when operating the pressure washer, stop and discontinue use. Continuing to operate a damaged unit could result in serious personal injury. NOZZLE MAINTENANCE See Figure 3. WARNING: NEVER perform maintenance on the nozzles without first turning off the pressure washer, relieving the water pressure in the trigger handle, and locking the lock out on the trigger handle (if one is included with your pressure washer). NEVER point the nozzles or spray bar at your face or at others. Failure to follow these instructions could cause the nozzles or high pressure water to eject and result in an eye injury or other serious personal injury. When shipped, two nozzles are pre-assembled to the surface cleaner. These nozzles are appropriate for use with pressure washers operating at up to 2,300 psi with a maximum flow rate of 1.4 gpm. Excessive pump pressure (a pulsing sensation felt while squeezing the trigger and/or a higher vibration in the surface cleaner) may be the result of a clogged or dirty nozzle. n Turn off the pressure washer and shut off the water supply. With the surface cleaner on the ground, pull trigger to release water pressure. n Disconnect surface cleaner from spray wand. n Remove the U-clip from the nozzle holder, then pull nozzle to remove. NOTE: Never point the spray bar openings at your face. n Using a fine needle, 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 Reinstall the nozzle and U-clip. NOTE: Make sure the nozzles are securely in place before using. n Reconnect the surface cleaner to the spray wand. n Turn on the water supply and start the pressure washer. CHANGING THE HIGH PRESSURE FILTER See Figure 4. Once you have cleaned the deck nozzles, if the water still doesn't flow freely from the spray bar, it may be necessary to replace the high pressure filter. To replace the filter: n Turn off the pressure washer and shut off the water supply. With the surface cleaner on the ground, pull trigger to release water pressure. n Disconnect the surface cleaner from the spray wand. n Place a flat head screwdriver in the slot of the high pressure filter inside the cleaning deck inlet plug, shown in figure 4, and BRUSH SKIRT U-CLIP FINE NEEDLE NOZZLE HIGH PRESSURE FILTER SPRAY BAR Fig. 3 CLEANING DECK INLET PLUG Fig. 4 turn counterclockwise. This will unscrew the filter and allow it to be removed. n Once the filter is removed from the inlet plug, replace it with a new filter (not included). n Using a flat head screwdriver, turn the filter clockwise until it can no longer be seen over the top of the inlet plug.
