1: Disconnect all water connections.
2: Turn on the machine for a few seconds, until
the water which had remained in the pump
exits, turn off immediately.
3: Do not allow high pressure hose to become
kinked.
4: Store the machine and accessories in a
room which does not reach freezing tempera-
tures. DO NOT store near furnace or other
sources of heat as it may dry out the pump
seals.
CAUTION
Failure to follow the above directions will result in
damage to the pump assembly and accessories
and will void the warranty.
Kärcher® also recommends the regular practice of
using a pump protector like “Kärcher® Pump
Guard” to prevent cold weather damage during
storage in the winter months.
Initial Use
All Kärcher pumps ship with oil already inside di-
rect from the factory. There is no need to add oil.
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 ser-
vice center in your area online at www.karcher-
residential.com)
(with or without detergent). Pre-rinse cleaning
surface with fresh water. If using detergent, apply
to surface at low pressure (for best results, limit
your work area to sections of approximately 6
feet and always apply detergent from bottom to
top). Allow detergent to remain on surface 1-3
minutes. Do not allow detergent to dry on sur-
face, if surface appears to be drying, simply wet
down surface with fresh water. If needed, use
special wash brush attachment (not included)
to remove stubborn dirt. Rinse at high pressure

the spray nozzle approximately 3-6 inches from
the cleaning surface. Always clean from top 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.
