1: 

Disconnect all water connections.

  

2: 

Turn on the machine for a few seconds, until 

the water which had remained in the pump 

exits, turn off immediately.

  

3:

 Do not allow high pressure hose to become 

kinked.

  

4:

 Store the machine and accessories in a 

room which does not reach freezing tem-

peratures. DO NOT store near furnace or 

other sources of heat as it may dry the pump 

seals.

  

CAUTION

 

Failure to follow the above directions will  

 

result in damage to the pump assembly and  

 

accessories and will void the warranty.

 

  It is highly recommended to use Kärcher's 

Pump Guard (part number 9.558-998.0) be-

fore winter storage and during the cleaning 

season to protect the pump from freezing and 

premature wear.

Initial Use

All Kärcher pumps ship with oil already inside direct 

from the factory. There is no need to add oil.

Pump Inspection

You should routinely make a visual inspection of 

the pressure washer’s pump. If you notice oil leak-

ing around the pump seals, you should take the 

pressure washer to a Kärcher-Authorized Service 

Center for repair. (You can locate a service center 

in your area online at: www.karcher-usa.com/

service).

Pump Maintenance

The pump on your Kärcher pressure washer does 

not require maintenance. Any attempts to service 

or alter the pump may damage your pressure 

washer and void your product warranty.

Carry out maintenance tasks for the engine accord-

ing to the specifi cations provided in the operating 

instructions provided by engine manufacturer.

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 sec-

tions 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.
