1. Unit Start-Up

English

CAUTION:

-FIRE HAZARD! Do not operate the high-pres- sure cleaner if fuel has been spilled. Instead, move the machine to a different location and avoid creating sparks of any kind.

-Do not store, spill or use engine fuels near open flame or in the vicinity of devices featuring an open pilot flame, such as boilers, water heaters, etc., or device that may create sparks of any kind.

-Keep flammable items and materials away from the engine silencer (minimum distance: 2 meters).

-Do not operate the motor without the silencer, and check and clean the latter on a regular basis. Replace if necessary.

-Do not use the motor in woods, scrubs and grasslands without having a spark catcher attached to the silencer.

-Except during engine tuning, do not operate the engine with the air cleaner removed, or without a suitable cover over the air intake.

-Do not make adjustments to governor springs, governor linkages or other parts that may result in a higher engine RPM.

-BURN HAZARD! Do not touch hot silencers, cylinders or cooling fins.

-ASPHYXIATION HAZARD! Exhaust fumes are poisonous. Never operate the unit in enclosed rooms.

1.1 Unpacking the unit

Should you notice any transport damage during unpacking, notify your dealer immediately.

Because you care about the environment, please do not dispose of packaging components in regular domestic waste. Instead, take the items to a collection point for recycling.

1.2 Attaching the accessories

Mount the holding basket for the detergent (3 metal hoops) to the push handle.

Attach the push handle to the unit.

1.3 Engine

Prior to using the unit, read the operating instructions supplied by the engine manufacturer, and pay particular attention to the safety instructions.

Fill the fuel tank with unleaded petrol. Do not use a petrol/oil mixture for two-stroke engines.

The engine is supplied without engine oil. A certain amount of engine oil is packaged with the unit. Pour this engine oil into the oil filler hole on the engine.

Check the engine oil level. Do not start the engine if the oil level has dropped below the „MIN“ level. Top up oil if necessary.

1.4 Pump

The pump is filled with oil. An oil change is not required.

1.5 Water inlet

See „Specifications“ for connection data.

1.Screw male coupling (11) onto the machine. Do not overtighten.

2.Screw female coupling (10) onto male end of garden hose. Be sure the hose end is in good condition so a leak does not occur. Do not overtighten.

3.To connect, push female coupling onto male coupling all the way until it clicks twice to assure full flow of water to the pump.

Caution: Failure to push female coupling on all the way can damage the pump if allowed to run dry.

4.Turn on water supply: If leak occurs, retrace steps 1 to 3, making sure connections are tight and that couplings are not reversed.

Caution: The male and female connection are not the same thread size. Reversing the connections will damage the coupling and cause a water leak preventing the pump from priming properly.

1.6 Suction feed operation

To draw water from an open reservoir, proceed as follows:

Remove the threaded coupling from the unit’s water inlet, and directly connect a suction feed hose with filter (order no. 4.440-238) to the water inlet.

Set the metering ring on the detergent suction hose to zero.

Without the high-pressure hose being attached, operate the pump until a solid stream of water exits at the high-pressure outlet.

At this point, connect the high-pressure hose again.

Note: Dirt in the feed water could lead to the appliance being damaged. To avoid this risk, we recommend fitting a filter. A suitable filter with 3/4" connection (order no. 4.730-059).

1.7 Spray lance

To attach the spray lance to the hand gun, insert the spray lance into the bayonet coupling of the hand gun. Overcoming the spring pressure, firmly press the lance into the coupling and twist it a quarter-turn until it locks into place.

If required, you can use the additional spray lance extension.

2. Operation

2000 GM

2.1 Operating with high pressure

Start the engine while observing the engine manufacturer’s operating instructions.

Using the safety catch, unlock the handgun trigger and pull the trigger.

The working pressure can be variably adjusted by turning the spray lance on the outside (+/-).

2.2 Operating with detergent

Set the lowest working pressure with the spray - lance. No detergent can be drawn in with a high working pressure.

Hang the detergent suction hose into the detergent reservoir (not supplied with the unit).

To protect the environment, we recommend to use detergents sparingly. Observe the metering and/or mixing instructions provided on the pakkaging labels of the detergent supply containers.

By offering you an individualised range of cleaning and preserving agents, Kärcher guarantees trouble-free operation of the unit. Request more information or ask for our catalogue and/or individual information brochures on specific detergents.

Universal cleaner	Profi RM 555 ASF
This cleaning agent may be used undiluted.
Universal cleaner	Profi RM 555 ULTRA
Automotive cleaner	Profi RM 555 ULTRA
House and garden cleaner	Profi RM 565 ULTRA
Boat cleaner	Profi RM 575 ULTRA

Before using, these cleaning agents must be diluted with 9 parts of water (1:9).

Note:

Only cleaning agents approved by the equipment manufacturer may be used. Unsuitable detergents may damage the unit and the object being cleaned.

We recommend the following cleaning method:

Step 1: Pre-soaking the area to be cleaned.

Spay the detergent sparingly onto the area to be cleaned and allow to soak for 1 – 4 minutes.

Step 2: Cleaning step

Using the high-pressure jet, flush the area clean.

After using a detergent, the unit should be flushed with clean water. To do this, hang the detergent suction hose into a container filled with clean water, and operate the pump for approximately 1 minute.

2.3 Work interruptions

To prevent damage caused by overheating water, switch OFF the pump during work breaks that are longer than 10 minutes.

2.4 Switching OFF the unit

After operating the unit with water having a high saline content (i.e., sea water), the unit should be flushed for 2 – 3 minutes with tap water while the handgun is open.

Set the throttle to the STOP position.

Close the water supply valve and unscrew the water supply line from the water inlet of the unit.

Actuate the handgun trigger until the unit is no longer pressurised.

Prevent inadvertent opening of the handgun trigger by locking it with the safety catch.

3. Care and Maintenance

English

3.1 Monthly or as required

Clean the filter on the detergent suction hose.

Clean the high-pressure nozzle.

Using a needle, remove possible blockages from the nozzle orifice. Afterwards, flush with water from the front.

Clean the strainer in the water inlet. It can easily be pulled out with a pair of pliers.

3.2Precautions in freezing temperatures

A unit that has not been completely drained may be damaged by water freezing inside the components. During the winter season, it is recommended to store the unit in a heated area. If this is not feasible, the unit should be completely drained and flushed with antifreeze.

Draining the unit

–Remove the water feed hose and high-pressu- re hose from the unit.

–Allow the unit to operate for a maximum 1 minute until the pump and the lines have been purged.

Antifreeze

In the event that the unit is taken out of operation for extended periods, flushing the unit with an antifreeze is recommended. This practice also achieves a certain degree of corrosion protection.

4. Troubleshooting

This chapter contains a few helpful hints which may help you remedy small defects without requiring further assistance. In all other cases please contact the authorised customer service.

4.1 Unit does not run

Perform the maintenance procedures on the engine as outlined in the operating instructions issued by the engine manufacturer.

4.2Unit does not reach operating pressure

Set the spray lance to the maximum working pressure.

Clean the water inlet strainer.

Check the water supply volume.

Check all supply lines feeding the pump for possible leaks or blockage.

4.3 Strong pressure fluctuations

Clean the high-pressure nozzle. Remove dirt from the nozzle hole with a needle and then rinse out with water from the front.

4.4 Pump is leaking

Three drops per minute are normal. In the event that the exiting water volume is larger, contact the authorised customer service.

4.5 No detergent is being drawn in

Set the spray lance to the minimum working pressure.

Clean both the detergent suction hose and the filter, and check the hose for leaks.
