2. SAFETY INSTRUCTIONS  
BEFORE STARTING UP YOUR PRESSURE WASHER PLEASE  
CHECK YOU HAVE THE FOLLOWING:  
We recommend you purchase these items from a reputable store  
• RCD plug and socket that will interrupt electrical supply in an  
emergency  
• A typical garden hose (minimum length 7.5 metres) with suitable  
hose connection (Hoselock/Gardena type) to match the coupling  
on the machine (hose and connector not supplied).  
The mains voltage and supply indicated on the Rating Plate of the  
machine corresponds with that of the power source  
The insulation of the supply cable is not damaged  
Only earthed sockets should be used  
If you are using an extension cable it must be completely unwound  
from the cable drum and be the correct diameter:  
10 meter length of cable should have a cross section of 1.5 mm²  
30 meter length of cable should have a cross section of 2.5 mm²  
Safety Assurance  
As an added precaution, your pressure washer is fitted with a safety  
locking device on the Spray Gun.  
AFTER USE, ALWAYS REMOVE THE PLUG FROM THE SOCKET  
BEFORE CLEANING YOUR PRESSURE WASHER.

4. OPERATING YOUR PRESSURE WASHER  
If you have followed all the instructions so far, you are  
now ready to have fun cleaning the KARCHER way!!!  
Turn on the supply water and press the Spray Gun lever (No. 8) until  
the water flows freely and removes all air locks from the hoses  
You may now attach the Spray Lance (No. 6) or required accessory  
to the Spray Gun  
All accessories are bayonet fit, simply push in and twist  
until they click into position !  
Once water is flowing through the machine, you may now switch  
on your Karcher Pressure Washer using the Power Switch (No. 3)  
WHEN USING YOUR KARCHER PRESSURE WASHER ON  
THE HIGH PRESSURE SETTING, THE RECOMMENDED  
WORKING DISTANCE BETWEEN THE NOZZLE AND THE  
OBJECT OR SURFACE TO BE CLEANED IS 30 CM.  
ITCANBECLOSERIFREQUIREDFORPATIOSORMASONERY  
It is your responsibility to check the suitability of the surface to be cleaned.

4.1 High Pressure Operation  
Ensure the Spray Lance with Vario Power Nozzle (No. 6) or the Spray  
Lance with Dirt Blaster (No. 12) are attached securely to the Spray Gun  
(No. 8).  
Set vario power nozzle to high pressure mode  
"+".  
Aim the lance towards the object to be cleaned making sure the  
recommended working distance is used for reference (See Page 9).  
Release the safety ratchet on the Spray Gun and squeeze the trigger.  
Switch on the pressure washer (No. 2)  
The pressurised water jet alone is capable of fulfilling most  
cleaning tasks around the garden or on building work but  
detergent and wash brush are advantageous when cleaning  
vehicles or other paint finishes.  
4.2 Low Pressure Operation  
Dilute the detergent in a suitable container to the required concentra-  
tion before using. (The correct dilution is dependent on the degree of  
soiling of surface and is best determined by experience).  
Hang the Detergent Suction Tube (No. 1) in the  
Detergent Container.  
Set Vario Power Nozzle to low pressure mode "".  
Note: No detergent in high pressure mode  
Note: the Dirt Blaster (No. 12) is not for use in low pressure operati-  
on.  
Aim the Spray Gun towards the object to be cleaned, release the  
Safety Ratchet on the Spray Gun and squeeze the trigger to apply  
the detergent to the working area.  
Switch on the pressure washer (No. 2)  
10  
 
We recommend the following cleaning method:  
Step 1:  
Remove loose dirt by washing over the surface to be cleaned with the  
high pressure jet.  
Step 2:  
Spray on the detergent and leave for 1-4 minutes, so assisting the easy  
removal of fine dirt and associated greasy adhesions.  
Step 3:  
Finally, spray off the loosened dirt with the high pressure spray.  
4.3 End Of Operation  
ALWAYS REMEMBER TO RINSE YOUR PRESSURE WASHER  
AFTER USING DETERGENT BY HANGING THE DETERGENT  
SUCTION TUBE IN A CONTAINER WITH CLEAN WATER AND  
RUN THE PUMP FOR APPROXIMATELY ONE MINUTE IN LOW  
PRESSURE SETTING.  
In the event of a break of 5 minutes in the operation of your  
Karcher Pressure Washer, always switch off the pump to avoid  
damage due to overheating.  
Switch off the pressure washer by the Power Switch (No. 2) and  
unplug the Mains Electric Lead (No. 9) from the socket  
Close the water inlet (tap) and disconnect the hosepipe  
Release the trigger to remove all pressure from the machine  
and then secure the trigger with the Safety Ratchet to prevent  
accidental opening.

5. IMPORTANT – CARE AND MAINTENANCE  
To ensure prolonged life and trouble-free use of your  
Karcher Pressure Washer we strongly recommend  
that you always adopt the following procedures:  
Water  
Before use, always check the inlet filter for dirt or debris.  
Visually check to see if the nozzle is blocked by dirt or grit, if so, re-  
move the dirt from the nozzle hole with a needle and rinse with water  
from the front.  
Failure to do this will seriously damage your machine and invali-  
date the warranty.  
Connect the water supply hose and, without the lance attached,  
squeeze the trigger gun to run water through your pressure washer  
until the water flow is constant. Then plug in to the electric supply.  
Unless drawing water from an open water source such as a water  
butt, always have a minimum of 10 metres (25 feet) of uncoiled hose  
between the water tap and your machine. The internal diameter of  
the feed water hose should be 12 mm (1/2).  
Water Regulations require the use of a back-flow preventer valve at  
the tap end of the supply hose.  
Only use a full flow connector to connect the hose to the machine.  
Electricity  
If using an electrical extension lead it must be rated at a minimum of  
13 amps.  
Always fully uncoil any extension lead when used.  
Chemicals  
Use of chemicals other than those recommended by Karcher could cau-  
se significant damage which may not be covered by your warranty.  
After using chemicals, always run fresh water through your machine.  
12  
 
The high pressure hose of your Karcher Pressure Washer should not  
be mistreated. It is designed to withstand high pressure operation so  
vehicles should NOT run over it, nor should it be pulled across sharp  
or abrasive edges. These actions may weaken the hose and cause  
ballooning.  
IMPORTANT  
REMEMBER FROST WILL DAMAGE YOUR KARCHER  
PRESSURE WASHER IF IT HS NOT BEEN COMPLETELY  
EMPTIED OF WATER AFTER USE. ALWAYS STORE IN A  
FROST FREE AREA.
