PRESSURE WASHER
Before first use of the unit read these operating instructions and act in accordance with them
PRESSURE WASHER
PLEASE READ THIS LEAFLET CAREFULLY BEFORE OPERATING YOUR MACHINE.
WHAT IS A PRESSURE WASHER?
A Pressure Washer is essentially a powerful electric motor driving a set of pistons that force water through a small nozzle, thus creating a pressurised jet of water. This provides the cleaning power behind the Karcher Pressure Washer.
A Karcher Pressure Washer can be used for an endless list of applications around the home and garden. It provides an efficient, economical and labour saving way of cleaning with excellent results.
All Karcher domestic pressure washers are designed to run from a suitable cold water supply although some models will accept a water inlet temperature of between 40 °C and 60 °C.
Environmental Comment – Save water with high pressure.
The Karcher Pressure Washer is environmentally friendly enabling you to reduce your water consumption compared to a normal garden hose. A definite advantage with a metered water supply
OR
with the added benefit of suction mode, water can be drawn from an open container such as a water butt.

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!!!
• Assembly the Spray Gun (No. 8) and the high-pressure hose (No. 7), shown on page 19.
• Attach the high-pressure hose to the high-pressure outlet (No. 3) of
the unit.
• Safety Assurance
As an added precaution, your pressure washer is fitted with a safety locking device on the Spray Gun.
• Turn on the supply water and press the trigger of the Spray Gun
(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. 2).
• You can regulate your operating pressure on the Spray Lance (No. 6)
by rotating the Vario Nozzle.
Raise operating pressure …….. twist Vario Nozzle in direction “+”.
Reduce operating pressure ….. twist Vario Nozzle in direction “–”.
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.
IT CAN BE CLOSER IF REQUIRED FOR PATIOS OR MASONERY
It is your responsibility to check the suitability of the surface to be cleaned.
Karcher (UK) Ltd. cannot be held responsible for any damaged caused.
10
4.1 High Pressure Operation
• Ensure the Spray Lance with Vario Power Nozzle (No. 6) is 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. 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 with Detergent (chemicals)
• Dilute the detergent in a suitable container to the required concentrati- on 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
• Aim the Spray Gun towards the object to be clea- ned, 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).
4.3 Low Pressure Operation with Brush
When cleaning surfaces with a grease contamination – typically car paint- work that always has a greasy traffic film covering. Follow the
procedure of:
• Washing loose dirt away with the clean water high pressure spray.
• Apply the detergent in low pressure mode by removing the bayonet fit spray lance and fitting the Wash Brush to the Spray Gun.
• Leave for 2-4 minutes for the detergent to have maximum effect.
11
• With or without the pressure washer switched on, brush down the sur- face being cleaned, this physical agitation removes all trace of traffic film. Finally revert to the high pressure operation with the Spray Lance and complete the wash down.
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.
4.4 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 Locking Device to prevent accidental opening.
AFTER USE, ALWAYS REMOVE THE PLUG FROM THE SOCKET BEFORE CLEANING YOUR PRESSURE WASHER.

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, remo- ve 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 bet- ween 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.
• The high pressure hose of your Karcher Pressure Washer should not be mistreated. It is designed to withstand high pressure operation so vehic- les should NOT run over it, nor should it be pulled across sharp or abra- sive edges. These actions may weaken the hose and cause ballooning.
