Cleaning Procedure:
►Position the tip of the wand 6-8”
(15-20 cm) away from the surface to
clean at a 45°angle.
The color-coded quick connect
nozzles provide a wide array of spray
widths from 0° to 65° and are easily
accessible when placed in the
convenient nozzle holder.
0° spray angle = Red nozzle
For particularly stubborn accumulation
of grime. Not recommended for soft
materials like sidings, decks, painted
surfaces, cars.
15° spray angle = Yellow nozzle
For dirt accumulation over a surface.
25° spray angle = Green nozzle
For dirt accumulation over a large
surface.
40° spray angle = White nozzle
For moderate dirt accumulation over a
large surface.
Soap = Black nozzle
For operating with detergents or
cleaning with low pressure.
High pressure in nozzle area. Risk of
injury caused by improperly locked
nozzle.
▬Make sure you hear the "click" when
inserting the nozzle tip into the quick
connection.
▬Pull the nozzle to make sure it is
seated properly before operating your
unit.
To avoid serious injury never point
spray nozzle at yourself, other
persons or animals.
The pressure can be adjusted by
changing the speed of the engine
using the throttle lever.
Turning the throttle lever to the left can
increase the speed to get more
pressure.
Using the Accessories
Quick Connect Nozzles
Adjusting Water Pressure

English 13
Turning the throttle lever to the right
can decrease the speed to get less
pressure.
When adjusting the engine throttle to
the lowest setting, do not operate the
pump. This can cause the engine to
stall due to lack of power.
Detergents can only be applied with
the black detergent nozzle.
►Install the black detergent nozzle for
detergent application at low pressure.
►Fill the detergent tank with Kärcher
Brand Detergent.
►With the engine running, pull trigger
to operate unit.

Pump Inspection
You should routinely make a visual
inspection of the pressure washer’s
pump. If you notice oil leaking around
the pump seals, you should take the
pressure washer to a Kärcher
Authorized Service Center for repair.
(You can locate a service center in
your area online at:
www.karcher-service.com).
Carry out maintenance tasks for the
engine according to the specifications
provided in the operating instructions
provided by engine manufacturer.
With or Without Detergent
Pre-rinse deck and surrounding area
with fresh water. If using Kärcher Deck
Wash, apply to surface at low
pressure. For best results, limit your
work area to smaller sections of
approximately 25 square feet. Allow
Deck Wash to remain on surface 1-3
minutes. Do not allow detergent to dry
on surface. Rinse at high pressure in a
long sweeping motion keeping the
spray nozzle approximately 3-6 inches
from the cleaning surface. Always
clean from top to bottom and from left
to right. When moving on to a new
section of the cleaning surface, be
sure to overlap the previous section to
eliminate stop marks and ensure a
more even cleaning result.
With or Without Detergent
Pre-rinse vehicle with fresh water. If
using Kärcher Touchless Vehicle
Wash, apply to surface at low
pressure. For best results, clean one
side of vehicle at a time and always
apply detergent from bottom to top, do
not allow detergent to dry on surface.
If needed, use special wash brush
attachment (not included) to remove
stubborn dirt. Rinse at high pressure
in a sweeping motion keeping the
spray nozzle approximately 6-8 inches
from the cleaning surface (distance
should increase when rinsing
pin-striping or other sensitive
surfaces). Always clean from top to
bottom and from left to right. For best
results, wipe surface dry with a
chamois or soft dry cloth.
