operation If the spray is too close it can damage the cleaning surface. USING the NOZZLES See Figure 13. Each of the nozzles has a different spray pattern. Before starting any cleaning job, determine the best nozzle for the job. The following chart offers some general guidelines to help you choose the best nozzle for your application. NOTE: Always try nozzles in an inconspicuous area first. Spray Wand Variable Spray Type Fan spray (+) Application For general purpose or large surfaces • General cleaning of dirt, mud, and grime • Cleaning roofs, gutters, and downspouts • Removing light mildew stains • Removing algae and bacteria build-up from pools • Rinsing surfaces in preparation for ­painting Turbo Soap spray (-) Rotational - Pencil Spray For all detergent applications Pencil jet nozzle rotates at high speed to increase intensity and cleaning area of the spray. Spray pattern will cover an area from 4 to 8 in. wide depending on distance between wand and surface being cleaned. • Rust removal • Non-painted metal or plastic tank cleaning • Washing concrete • Removing gum from sidewalks • Boat cleaning • Cleaning dirty garage floors • Removing mud and clay from hard surfaces like concrete, brick, or stone  WARNING: NEVER change nozzles without engaging the lock-out on the trigger handle and never point the wand at your face or at others. The quick-connect feature contains small springs that could eject the nozzle with some force. Failure to heed this may cause personal injury. n Turn off the pressure washer and shut off the water supply. Pull trigger to release water pressure. n Engage the lock-out on the trigger handle by pushing the trigger lock button to the right. n Push the nozzle into place in the spray wand. Rotate clockwise to secure the nozzle in the spray wand. To disconnect a nozzle from the trigger handle once the cleaning job is complete: n Turn off the pressure washer and shut off the water supply. Pull trigger to release water pressure. n Push in on the spray wand and rotate clockwise to remove. VARIABLE FAN SPRAY WAND The variable fan spray wand can be used to create different spray patterns, from a full fan spray to a direct stream spray. When using the fan spray, begin with the lowest pressure and adjust to higher pressure, spraying far enough from the material being cleaned to avoid damaging the surface. OPERATING THE PRESSURE WASHER See Figure 14. Use only detergents designed for pressure washers. Many detergents may require mixing prior to use. Prepare cleaning solution as instructed on the solution bottle. To clean: n Pour detergent in the detergent tank. n Install the variable fan spray wand. n Apply detergent at low pressure (- setting on the spray noz- zle). n Start the pressure washer and spray the detergent on a dry surface using long, even, overlapping strokes. To prevent streaking, do not allow detergent to dry on the surface. To rinse: n Using the variable fan spray wand, adjust the spray to the high pressure setting (+). NOTE: The pressure washer does not dispense detergent when on the high-pressure setting. n Spray away from the rinsing surface for approximately 10 seconds to allow any remaining detergent to be flushed from the line. n Start at the top of the area to be rinsed and work down, overlapping the strokes. moving the pressure ­washer To move the pressure washer: n Turn the pressure washer off. Point nozzle in a safe direction and pull trigger to release water pressure. n Tilt the machine toward you until it balances on the wheels then roll the machine to the desired position. 10
