Water Supply (Cold Water Only) • Water hose must be at least 3/4 inch in diameter. • Flow rate of water supply must not fall below 2.5 GPM (gallons per minute). • Flow rate can be determined by running the water for one minute into an empty 5-gallon container. • The water supply temperature must not exceed 104°F/40°C. • Never use the pressure washer to draw in water contaminated with solvents, e.g. paint thinners, gasoline, oil, etc. • Always prevent debris from being drawn into the unit by using a clean water source. We strongly recommend that this high pressure washer not be left running for periods of 5 minutes or longer without the trigger gun being engaged. This Kärcher high pressure washer is equipped with thermal protection to extend the life of your pressure washer. The thermal protector will automatically activate at a predetermined high temperature ejecting hot water before resetting. This ensures that the pump does not become damaged.

Step 1 Attach the handle to the frame of the pressure washer. Align holes, insert bolt, add lock washer and tighten with knob. Step 2 Check oil level. Oil level should always be between the “FULL” and “ADD” marks on the dipstick. Be sure the machine is level when checking the oil level. (Refer to the engine’s operating manual for seasonal grades.) 3 Important! Do not run the engine with a high or low oil level as this can cause engine damage.

If the engine fails to start after 3 pulls squeeze the trigger gun to release pressure, and repeat step 7. USING THE ACCESSORIES Vario spray wand The Vario spray wand allows you to adjust the cleaning pressure. To clean at maximum pressure, the Vario wand must be positioned to the high pressure setting (+). To apply detergent, the wand must be positioned to the low pressure setting (-).

For low pressure turn wand collar in the minus (-) direction. 5 WARNING TO AVOID SERIOUS INJURY, NEVER POINT SPRAY NOZZLE AT YOURSELF, OTHER PERSONS OR ANIMALS WORKING WITH DETERGENT Detergents can only be applied at low pressure (-). For best results see Cleaning Tips on pages 8 & 9 for specific information on how to clean different surfaces. Step 1 Install the Vario spray wand and set the Vario spray wand to the low pressure setting (-) by turning the wand collar. The wand must be set in the low pressure (-) position to apply detergents.
