Working Advice

General
Ensure that the pressure washer is on level ground.
Do not overreach with the high pressure hose or move the
pressure washer by pulling the hose, this could cause the ma-
chine to become unstable and fall over.
Do not kink or drive a motor vehicle over the high pressure
hose. Do not expose the high pressure hose to sharp edges or
corners.
 Never use a roto nozzle or pencil jet to clean motor vehi-
cles.
Working advice for cleaning with detergents
 Only use cleaning agents suitable specifically for high
pressure washers.
We recommend that you use detergent sparingly for the sake
of the environment. Observe the recommended dilution on
the detergent label.
The high-pressure foam nozzle supplied with this product in-
cludes a regulator to control detergent use. Adjust as re-
quired.
Recommended cleaning method
Step 1: Select the fan jet setting on the 3 in 1 nozzle and re-
move the heavy dirt.
Step 2: Attach the foam bottle and spray on the detergent
sparingly.
Step 3: Rinse off the loosened dirt and detergent using the
fan jet setting on the 3 in 1 nozzle.
Note: When cleaning vertical surfaces, apply the detergent
from bottom to top. When rinsing off, work from top to bot-
tom.

Bosch Power Tools
Use with alternative water sources
The power washer is self-priming and enables water to be
drawn in from containers or natural water sources. It is IM-
PORTANT that the water filter is in clean condition when in-
serting it at the water inlet, and that only clean water is drawn
in.
Open tanks/containers and natural water sources
Use the Self Priming accessory kit comprising:
– Inlet strainer with non return valve
– 3 m reinforced supply hose
– Universal coupling to the pressure washer
This enables the pressure washer to draw water up to 0.5 m
above the water level in the source in approximately 15 sec-
onds.
Fully immerse the 3 m hose into the water to displace the air
in the hose. Connect the 3 m hose to the power washer and
make sure that the inlet strainer remains under water.
With the spray gun removed, switch the power washer on and
operate it until water flows uniformly out of the high-pressure
hose. If no water is coming out of the high-pressure hose after
25 seconds, switch the power washer off and check all con-
nections. As soon as water flows out of the high-pressure
hose, switch the power washer off and connect the spray gu-
nand spray lance to begin with the work.
It is important that hose and couplings are of good quality and
are tightly connected, and that the seals are undamaged and
properly inserted. Loose connections can impede the priming
(drawing in).
Water Tanks with outlet connections
When connecting the pressure washer to a water tank with a
suitable tap outlet, first connect the supply hose (not provid-
ed) to the tank outlet, open the tap to allow the water to dis-
place all the air in the hose and then connect to the pressure
washer.
Possible Cause
Plug not connected
Mains socket faulty
Fuse faulty/blown
Extension cable damaged
Motor protector has activated
Frozen
Fuse faulty/blown
Motor protector has activated
Wrong mains voltage
Fuses incorrectly rated
Nozzle partly blocked
Corrective Action
Connect plug
Use another socket
Replace fuse
Try without extension cable
Allow to cool for 15 minutes
Wait for pump/water supply hose/accessory to
thaw
Replace fuse
Allow to cool for 15 minutes
Check that mains voltage corresponds to specifica-
tions on the model tag
Change to a mains supply higher than the pressure
washer amp consumption
