Use and Maintenance Procedures :

1. Before using the machine 2. Installing the high-pressure hose 3. Starting up the machine4. How to use the nozzle5. How to stop the machine6. Maintenance of the machine pump

5

1. Before using the machine

a) Check the machine’s oil level MUST be above “LOW”

b) Make sure the gasoline tank is filled

2. Installing the high-pressure hose

a) Attach the hose and spray gun before turning on the machine

b) Connect the hose to the spray gun and the water outlet c) Make sure all connections are tight/strongd) Make sure the hose is unrolled/not twisted

7Spray gun High-pressure hose (outlet)

e) Check the filter for incoming water and clean it if there is dirt

f) Turn on the water for 30 seconds to remove dirt in the hoseg) Attach the hose to the water inlet with water inside to help

start the flowh) Remove air bubbles in the water hose

3. Starting up the machine

a) Make sure all water hoses are attachedb) Position the switch to OFF – Turn on the CHOKE handle – then

pull the starter cord a few times (to start up) c) Next, turn off the CHOKE handle – position the switch to ON

9

Starter cord Switch CHOKE handle

d) Pull the starter cord hard using a long pull. Keep trying until the machine starts up

e) When it is on turn the choke handle back to the off position

f) Adjust the gasoline with the handle

g) Tighten the pressure setting on the compressor

h) Try to spray out water without the nozzle before pumping water and remove air bubbles.

4. How to attach the nozzle

a) Insert the nozzle into the end of the spray gun

b) Push with the palm of the hand to tighten

c) To remove the nozzle, pull down the end of the spray gun

d) Take care so that the nozzle does not fall

12

Nozzle Types

• Black = for disinfectant/detergent

• For light spraying• White (40°)• Green =spray 25°

• For powerful spraying• Yellow = spray 15°• Red = spray 0°

5. How To Turn Off The Machine

• Rinse out the remaining soap in the hose with clean water

• Turn down the machine’s power to the lowest level

• Leave the machine on for a few moments on low power

• Turn the switch to OFF• Release pressure that remains after

the machine is switched off• Lock the spray gun when not in use• Turn off the water supply and remove

the hose• Roll up the hose and clean the machine 14

Detergent

1. How to make a detergent solution

2. How to use detergent in the machine

3. How to rinse the detergent hose

1. How to make a detergent solution

18

1. The detergent provided (Karcher) does not need to be dissolved

2. Ordinary household liquid detergent may be used (dishwashing soap, floor cleaner etc.)

Dose: 1/3 liquid soap mixed with 2/3 water3. Use a filter on the detergent hose4. Use 20 liter jerricans of detergent for sufficient

sucks in detergent from the jerrican

19

3. How to rinse the detergent hose

a) Use the black nozzleb) Move the end of the detergent hose from the

jerrican to a plastic bottle (600 ml) filled with clean water

c) Press the spray gun until all the water has been sucked out of the bottle

d) Remove the plastic hose and store it

Things to remember

• After spraying detergent, rinse with high-pressure spray

• Spray equipment DANGEROUS (Always use full PPE when washing)

• Use of the yellow and red nozzles must be done with care they can cause damage/injury

• Always rinse out the detergent after using the machine

• Always clean the machine after each use• Store in a dry and clean place
