For your safety
Before you use the cleaner for the first time,
read these operating instructions and take
special note of the accompanying booklet
“Safety Instructions for High-pressure
Cleaners” No. 5.951-949.
Use of the cleaner
Use this cleaner exclusively for
– cleaning with high-pressure jet and
detergent (e.g. cleaning of machines,
vehicles, buildings, tools)
– cleaning with high-pressure jet without
detergent (e.g. cleaning facades,
terraces, gardening equipment).
For stubborn dirt we recommend the dirt
blaster as an optional accessory.
Safety features
Relief valve with pressure
switch
On reducing the flow rate with the pressure
and flow control, the relief valve opens and
part of the water runs back to the suction
side of the pump.
If the lever is released, the pressure switch
switches the pump off. If the lever is
retracted, the pressure switch switches the
pump on again.
Safety valve (only in HD 690/
HD 690 SX)
The safety valve opens when the maximum
allowable operating pressure is exceeded:
the water flows back to the suction side of
the pump.

English Operating Instructions HD 645 / HD 650 (SX) / HD 658 / HD 690 (SX)

Relief valve, pressure switch and safety
valve are set and sealed in the factory.
Adjustments are made only by Customer
Service.
Warranty
The warranty terms issued by our authorised
marketing company are valid in every
country. We remedy any fault in the cleaner
free of charge within the warranty period
providing the cause of the fault proves to be
a material or manufacturing error.
The warranty only becomes operative
when your dealer has completed the reply
card accompanying the sale of the unit, has
stamped and signed it and you have then
sent the reply card to the marketing
company in your country.
Should you wish to call upon the guarantee,
please apply to your dealer or nearest
authorised Customer Service centre taking
along also the accessories and bill of sale.
Preparing the cleaner for
use
Unpack the cleaner
– When unpacking the cleaner, check the
contents of the packaging. If there has
been any damage in transit inform the
dealer.
– Do not dispose of the packaging with the
household rubbish, hand it in at the
appropriate collection point for recycling.

Using the cleaner for the
first time
Electrical connection
Caution!
The voltage specified on the model
rating plate must correspond to the
voltage supplied.
Caution!
Use an extension cable whose cable
cross-section is adequate (see
“Technical Specifications”) and unreel
it completely from the cable drum.
For connected loads see model rating
plate/Technical Specifications.
Water connection/suction
feed operation
Connection to water main
Caution!
Pay attention to the regulations of the
water supply company; according to
DIN 1988, the cleaner may not be
connected direct to the public drin-
king water supply. A short-term con-
nection via a non-return valve
(Order no. 6.412-578) is allowed.
For connected loads see Technical
Specifications.
Connect a supply hose (not supplied) to
the water outlet on the cleaner and to the
water inlet (e.g. water tap).
Open water inlet.
Suctioning water from an open
container
Screw suction hose with filter
(Order no. 4.440-238) to the water
outlet.
Venting the unit
To vent the unit, unscrew the nozzle and
leave the unit running until the water
exits with no air bubbles.
Switch off the unit and screw the nozzle
back on.
Operating the cleaner
Danger!
Observe the relative safety
regulations when using the cleaner at
filling stations or other high-risk
areas.
Caution!
Only clean engines in places which
have appropriate oil separators
(protection of the environment).
Caution!
Only wash animals with the low-
pressure fan jet (see “Selecting the
type of spray”).
Operating with high pressure
The cleaner is equipped with a pressure
switch. The motor only starts up when the
lever is retracted.
Unroll the required length of high-
pressure hose from the hose reel.
Fig. 9
Caution!
Should the hose-reel crank handle
protrude out in front, this should be
pulled out and put on again facing the
housing.
Press safety switch and retract lever.
Set unit switch to “I”.
Adjust operating pressure and flow rate
(+/–) by rotating the pressure/flow
control (infinitely variable).

20
Selecting the type of spray
The handgun must be closed.
Rotate the housing of the nozzle until the
desired symbol corresponds with the
marking:
High-pressure pencil jet
for particularly stubborn accu-
mulation of grime.
Low-pressure fan jet
for operating with detergent or
cleaning with negligible pressu-
re.
High-pressure fan jet
for dirt accumulation over a lar-
ge surface.
Operating with detergent
Caution!
Unsuitable detergents can harm the
cleaner and the object which is to be
cleaned. Use only detergents which
are released by Kärcher. Proportions
of detergent to be used and accom-
panying instructions should be noted
carefully. Use detergents sparingly
out of consideration for the environ-
ment.
Kärcher cleaning agents guarantee
trouble-free operation. Please seek advice
or ask for our catalogue of information
sheets on cleaning agents.
– Active cleaner RM 31 ASF
– Universal cleaner RM 55 ASF
– Active wash RM 81 ASF
Fill detergent reservoir.
Set nozzle to .
Set detergent metering valve to the
centre position. Adjust dosage with + or
– as required.
Recommended cleaning methods
Spray detergent sparingly over the dry
surface to be cleaned and let it take
effect but not dry out.
Spray off (rinse off) the loosened dirt
using the high-pressure spray.
When you have finished the operation,
set detergent metering valve to “0” and
switch the cleaner on for about 1 minute
and rinse it clear of detergent.
Interrupting the operation
Release lever, the cleaner switches off.
Retract lever again and the cleaner
switches on again.
Switching the cleaner off
Set unit switch to ”0” and pull out power
plug.
Close water inlet.
Retract lever until the cleaner is without
pressure.
Press safety switch to secure lever
against being activated unintentionally.
Transporting the cleaner
To transport the cleaner over relatively
long stretches, take hold of it by the
handle and pull it along behind you.
To transport it up steps or over ledges
pick it up by the handle.
Empty the detergent reservoir before
transporting it horizontally.
Storing the cleaner
Place the handgun in the support.
Reel in the high-pressure hose and hang
it over the hose rest.
Wind the high-pressure hose on to the
hose reel.
Coil the connecting cable round the
cable/hose rest.

Protection from sub-zero
temperatures
Caution!
Water which has frozen in the cleaner
can destroy parts of it. At best store
the cleaner in a heated room during
the winter or empty it or rinse it
thoroughly with antifreeze.
Empty the cleaner
– Unscrew supply hose and high-pres-
sure hose from the cleaner.
– Leave the cleaner running until the
pump and lines have emptied (max.
1 minute).
Putting in antifreeze
For longer intervals between operations,
pumping antifreeze through the cleaner
is to be recommended. By this means
also you obtain a sure protection against
corrosion.
Care and maintenance
Danger!
Before undertaking any care or
maintenance work on the cleaner,
pull out the power plug.
Caution!
When changing the oil, dispose of
any waste oil only at authorised
collection points.
Safety inspection/
maintenance contract
You can arrange with your dealer to have
a regular safety inspection carried out or to
have a maintenance contract. Please seek
advice on this.
Each time before operating
the cleaner
Check connecting cable for damage
(risk of getting an electric shock), have
a damaged connecting cable replaced
without delay by authorised Customer
Service personnel or an electrician.
Check high-pressure hose for damage
(danger of explosion), replace
a damaged high-pressure hose
without delay.
Check cleaner (pump) for any leaks.
Three drops per minute are allowable
and can appear on the underside of
the cleaner. Seek the help of Customer
Service if leaks are more serious.
Every week
Check oil level in oil reservoir: if the oil is
milky (water in oil), seek the help of
Customer Service immediately.
Clean the strainer at the water outlet.
Clean the filter at the suction hose for
detergent.
Annually or after
500 operating hours
Change the oil
– For oil quantity and type see
Technical Specifications.
– Undo fastening screws, remove unit
cover, remove cover of oil reservoir.
– Lay cleaner on its side and drain oil
into a suitable container.
– Fill slowly with fresh oil; air bubbles
have to escape.
