– Position parallel to travel direction: The

return water from the high-pressure

pump flows into the float tank when the

overflow valve is open.

Note: If the trigger gun is closed in this

ball tap position, the device may switch

off after a few minutes due to too high

temperature (see Troubleshooting/ER-

ROR 3).

– Position lateral to travel direction: The

return water of the high-pressure pump

flows into the water tanks when the

overflow valve is open.

Place the actuation lever of the return

flow valve ball tap parallel to the travel

direction (20L).

Close the supply tap of the water tanks.

Set the actuation lever of the return flow

valve ball tap lateral to the travel direc-

tion (500L).

Open the supply tap of the water tanks.

Note: The device can only be operated

when the front cover is closed. If the front

cover is opened, the device shuts down

and the indicator light is on.

Note: Due to the bleeding procedure, the

speed of the motor may vary until the final

operating pressure has been reached.

Unlock the emergency-stop switch by

pulling.

Open rear cover.

Establish the water supply.

Insert the key into the key switch.

With cold engine only:

To preheat the motor, turn the key

switch to the left and hold it until the in-

dicator light preheating goes out.

Turn key switch to position "I". The indi-

cator lamp for operational readiness

lights up.

The control voltage is switch on and the

display shows the operating status.

Turn the key switch to the right until the

motor is running.

Set the appliance switch to operation

with cold/ hot water.

Release the trigger gun. To do so, push

the safety catch towards the back.

Open the hand spray gun.

Set the power switch to "0/OFF“ (burner

off).

DANGER

Scalding danger!

Set the power switch to the desired

working temperature (max. 100 °C).

The burner is switched on.

HDS 9/50, HDS 13/35 only (optional with

HDS 13/20, HDS 17/20):

Note: If the motor speed is increased, the

operating pressure also rises. This can be

read from the pressure gauge.

– Increasing the speed:

Push up the lever of the speed control.

– Reducing the speed:

Push down the lever of the speed con-

trol.

HDS 13/20, HDS 17/20 only:

Set (+/-) the working pressure and

quantity by turning the pressure/ quan-

tity regulation mechanism at the hand

spray gun.

DANGER

Risk of injury! When adjusting the pressure/

quantity regulation, make sure that the

screw connection of the spray lance does

not become loose.

HDS 13/20, HDS 17/20 only:

ATTENTION

Unsuitable detergents can cause damage

to the appliance and to the object to be

cleaned.

– For considerate treatment of the envi-

ronment use detergent economically.

– Observe the dosage and other instruc-

tions provided with these detergents.

– Use only those detergents approved by

the manufacturer of the appliance.

– Kärcher detergents ensure smooth

functioning. Please consult us or ask for

our catalogue or our detergent informa-

tion sheets.

Place the detergent suction hose in a

container filled with detergent and tight-

en the screw cap.

Set dosing value for detergent to the

desired concentration.

Note: To prevent detergent flowing back

into the float tank or water tanks during op-

eration with detergent with the trigger gun

closed, ensure the detergent dosing valve

is closed.

HDS 13/20, HDS 17/20 only (optional):

Note: The (optional) speed control attach-

ment kit is essential when operating weed

removal!

This must be operated in accordance with

Weed Removal operating instructions WR

20/WR 50, Part no. 5.967-071.0!

The following information must also be ob-

served:

Push the lever of the speed control

down as far possible.

Set the device switch to the "Weed re-

moval" operating mode.

1 TEMP LOW appears on display: Heat-

ing-up time in progress (approx. 2 min-

utes)

2 TEMP OKAY appears on display:

Perform weed removal.

Close the hand spray gun.

Secure the trigger gun. To do so, push

the safety catch towards the front.

Note: If the trigger gun is closed, the motor

continues to run at idling speed. The water

therefore flows between float tank and

high-pressure pump and is heated up.

Once the maximum permissible tempera-

ture (55 °C) has been reached, the temper-

ature sensor motor is switched off at the

water inlet. After it has cooled down to be-

low 50 °C, the device can be started up

again.

HDS 13/20, HDS 17/20 only:

Set dosing value for detergent to "0".

Open the hand spray gun and rinse the

appliance for at least 1 minute.

DANGER

Danger of scalding by hot water. After oper-

ation with hot water, the device must be op-

erated with open end handgun with cold

water for at least two minutes.

ATTENTION

Risk of damage! Never stop the motor un-

der full load when the trigger gun is opened.

Set the power switch to "0/OFF“ (burner

off).

Close the hand spray gun.

Motor regulates to reach dry run speed.

Turn the key switch to "0". The opera-

tion readiness indicator lamp goes off.

The control voltage is switched off and

the display goes out.

With external water supply: Shut off wa-

ter supply.

Activate trigger gun until device is pres-

sure-less.

Secure the hand spray gun using the

safety catch so that it doesn't open ac-

cidentally.

With external water supply: Disconnect

the water hose from the water inlet and

coil up the water hose onto the hose

reel.

Coil the high-pressure hose onto the

hose reel.

To protect from freeze damages, the appli-

ance must be flushed with antifreeze.

Note:Use normal glycol-based anti-freez-

ing agents for automobiles.

Note: Observe handling instructions of the

anti-freeze agent manufacturer.

A certain corrosion protection is achieved

with this as well.

Check the coolant circuit of the motor

for sufficient antifreeze, refill antifreeze

as needed.

See Maintenance Procedures "Check

and refill the coolant“.
