Preparation
Oil Level
► Turn the oil gauge dipstick counter clockwise; remove it and clean it with a clean cloth.
► Fully reinsert the oil gauge dipstick and pull it out to check the oil level.
► If the oil level is halfway up the dipstick or below, refill with SAE 10W-30 oil through the dipstick hole until the oil level reaches 3/4 up the dipstick or until it reaches the bottom lip of the dipstick hole as shown.
Always use SAE 10W-30 oil.
Oil crankcase capacity: 0.6L.
► Reposition the oil gauge dipstick and tighten it by turning clockwise.
► Engine oil should be changed after the first 5 hours, then every 50 hours.
Fuel Level
► If it is necessary to add fuel, first make sure the engine is OFF, and then remove the fuel cap by turning it counter clockwise.
► When refueling, make sure the fuel filter is in place and keep in mind all safety precautions.
► Use clean unleaded gasoline with a minimum of 87 octane. DO NOT use old gas. DO NOT mix oil with gasoline.
Fuel tank capacity: .79 Gallons (3.0 Lt)
Air Filter

Operating Instructions
Starting Procedure:
► Connect garden hose.
► Connect spray gun and pressure hose.
► Open water source.
► Start the Engine
- Turn the engine switch to "ON" position
- Move choke lever to "CLOSE" position.
- Turn the fuel valve to "ON" position.
- Put the throttle lever to the "FAST" position.
- Pull trigger on spray gun to release pressure.
- Locate recoil cord and pull slowly until resistance is felt. At this point, pull rapidly to start engine.
- After the engine has started, turn the choke lever to "OPEN" position.
NOTE: If unable to start the engine, repeat the above operation one or two times.
NOTE: If the temperature is higher, such as during summer or if the engine is hot, choke valve should be switched to "OPEN" position before starting
Cleaning Procedure:
► Position the tip of the wand 6-8” (15-20 cm) away from the surface to clean at a 45°angle.
Using the Accessories
Quick Connect Nozzles
The color-coded quick connect nozzles provide a wide array of spray widths from 0° to 65° and are easily accessible when placed in the convenient nozzle holder.
0° spray angle = Red nozzle
For particularly stubborn accumulation of grime. Not recommended for soft materials like sidings, decks, painted surfaces, cars.
15° spray angle = Yellow nozzle
For dirt accumulation over a surface.
25° spray angle = Green nozzle
For dirt accumulation over a large surface.
40° spray angle = White nozzle
For moderate dirt accumulation over a large surface.
Soap = Black nozzle
For operating with detergents or cleaning with low pressure.
Adjusting Water Pressure
The pressure can be adjusted by changing the speed of the engine using the throttle lever.
Turning the throttle lever to the left can increase the speed to get more pressure.
Turning the throttle lever to the right can decrease the speed to get less pressure.
Working with Detergents
Detergents can only be applied with the black detergent nozzle.
► Install the black detergent nozzle for detergent application at low pressure.
► Fill the detergent tank with Kärcher Brand Detergent.
► With the engine running, pull trigger to operate unit.
► Liquid detergent is drawn into the unit and mixed with water.
► Apply detergent to work area.
► Do not allow detergent to dry on surface.
► Always flush the detergent bottle with fresh water when the cleaning job is done, to rinse/flush any remaining detergents from the injection system.
NOTE: For best results see Cleaning Tips for specific information on how to clean different surfaces.
Taking a Break ...five minutes or more
► Move the engine stop switch to the OFF position. For engine details see engine manual.
► Release trigger and engage safety lock.
Shutting Down & Clean Up
► If detergents have been used, insert 1 gallon of fresh water into Detergent Bottle. Siphon water at low pressure for one minute to clear the line of residual detergent.
► Move the engine stop switch to the OFF position. Close the fuel valve.
► Turn off the water source.
► Press trigger to release water pressure.
► Release trigger and engage gun safety lock.
► Disconnect the garden hose from the water inlet on the unit.
► Disconnect the high pressure hose from the high pressure outlet. Store the high pressure hose in the gun holder assembly.
Winterizing & Long-Term Storage
It is highly recommended to use Kärcher Pump Guard (part number 9.558-998.0) before winter storage and during the cleaning season to protect the pump from freezing and premature wear.
► Turn engine switch to the OFF position.
► Disconnect all hoses.
► Unscrew cap from Pump Guard bottle.
► Remove internal seal.
► Reattach cap to Pump Guard bottle and remove black protective cap.
► Screw bottle into water inlet on pressure washer pump and squeeze.
► With ignition OFF, pull starter rope until fluid starts to exit.
► Unscrew bottle. Store or dispose properly. If Kärcher Pump Guard is unavailable, perform the following:
► Disconnect all water connections.
► Turn on the machine for a few seconds, until the water which remained in the pump exits. Turn off engine immediately.

Cleaning Tips
Deck Cleaning
With or Without Detergent
Pre-rinse deck and surrounding area with fresh water. If using Kärcher Deck Wash, apply to surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 square feet. Allow Deck Wash to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. Rinse at high pressure in a long sweeping motion keeping the spray nozzle approximately 3-6 inches from the cleaning surface. Always clean from top to bottom and from left to right. When moving on to a new section of the cleaning surface, be sure to overlap the previous section to eliminate stop marks and ensure a more even cleaning result.
Cars, Boats & Motorcycles
With or Without Detergent
Pre-rinse vehicle with fresh water. If using Kärcher Touchless Vehicle Wash, apply to surface at low pressure. For best results, clean one side of vehicle at a time and always apply detergent from bottom to top, do not allow detergent to dry on surface. If needed, use special wash brush attachment (not included) to remove stubborn dirt. Rinse at high pressure in a sweeping motion keeping the spray nozzle approximately 6-8 inches from the cleaning surface (distance should increase when rinsing pin-striping or other sensitive surfaces). Always clean from top to bottom and from left to right. For best results, wipe surface dry with a chamois or soft dry cloth.
House Siding
With or Without Detergent
Pre-rinse cleaning surface with fresh water. If using Kärcher Pressure Wash, apply to surface at low pressure (for best results, limit your work area to sections of approximately 6 feet and always apply detergent from bottom to top). Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface, if surface appears to be drying, simply wet down surface with fresh water. If needed, use special wash brush attachment (not included) to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 6 inches from the cleaning surface.
Cement Patios, Brick & Stone
With or Without Detergent
Pre-rinse cleaning surface with fresh water. If using Kärcher Pressure Wash or Degreaser, apply to surface at low pressure.

For removing extremely stubborn dirt, it may be necessary to move the spray nozzle even closer to the surface for greater dirt cutting action.
Patio & Lawn Furniture
