Operation Instructions Water Supply 1.) Make sure the water supply is clean. Debris can cause excess pump wear and reduce performance. 2.) An insufficient water supply will damage your pump. Make sure the water supply is steady and is 20% over the rated flow of your pump. Use a stopwatch to time how long it takes to fill a 5-gallon bucket with your garden hose. The bucket must fill faster than the times listed in the table below.
Operation Instructions Start-Up Instructions 1. Attach garden hose to water inlet. 2. Attach pressure hose to water outlet and gun. 3. Attach spray gun to lance. 4. Turn water supply ON. 5. Squeeze trigger to purge air from pump. 6. Insert nozzle. 7. Start engine. Shut-Down Instructions 1. Turn engine OFF. 2. Turn water supply OFF. 3. Squeeze trigger to relieve system pressure. 4. Remove garden hose. 5. Remove pressure hose. 6. Turn fuel valve OFF (if equipped). WARNING Skin puncture hazard.
Operation Instructions Applying Chemicals 1.) 2.) 3.) 4.) 5.) Install the black nozzle to spray chemicals onto the cleaning surface. Start the pressure washer according to the start-up instructions. Submerge the chemical hose in cleaning solution. Squeeze the spray gun trigger. The chemical injector will draw the chemical into the water stream. Apply chemicals evenly onto the cleaning surface. Allow the chemicals to react with the dirt, then clean at high pressure with green nozzle. 6.
Maintenance and Storage Maintenance Mode Before performing any maintenance on the pressure washer, it must be placed in maintenance mode. 1.) Turn off engine. 2.) Turn off water supply. 3.) Squeeze trigger to relieve system pressure. 4.) Shut off fuel valve. 5.) Unplug spark plug wire from spark plug, (see engine owners’ manual).
Maintenance and Storage Pump Oil Change 1.) Place a suitable container below the pump to catch used oil, then remove the oil fill cap and oil drain plug. 2.) Allow the used oil to drain completely, then reinstall the drain plug and tighten securely. 3.) Please dispose of used oil in a manner that is compatible with the environment. We suggest you take used oil in a sealed container to your local recycling center or service station for reclamation.
Maintenance and Storage Checking Oil Level for A157711 & A1577110 1.) Turn off engine, allow it to cool and disconnect the spark plug wire. 2.) Twist the dipstick cap until the arrow on the cap lines up with the arrow on the breather plug. Remove the dipstick from the breather plug. Then remove the breather plug from the pump. 3.) Wipe the dipstick off with a clean dry cloth. Insert the dipstick into the pump housing and remove it.
