For increased electrical safety to use a Residual Current De-
vice (RCD) with a tripping current of not more than 30 mA. Al-
ways check your RCD every time you use it.
If the supply cord is damaged, it must be replaced by a Bosch
Service Centre.
For products not sold in GB:
WARNING: For your safety, it is required that the plug at-
tached to the machine is connected with the extension cord.
The coupling of the extension cord must be protected against
splash water, be made of rubber or coated with rubber. The
extension cord must be used with a cable strain relief.
To prevent damage to the appliance, do not allow it to operate
dry.
Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains sock-
et elsewhere.

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 to clean motor vehicles.
F 016 L81 056 | (18.2.15)
WARNING! The Patio Cleaners supplied are only intended to
be used on flat surfaces! Do not attempt to use them on steps
or vertical surfaces. Never attempt to touch the rotating noz-
zle while operating the machine!
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: Loosening dirt
Attach the High Pressure Foam nozzle and spray on the deter-
gent sparingly.
Step 2: Removing dirt
Spray off the loosened dirt with the high-pressure spray.
Note: When cleaning a vertical surface spray off dirt/deter-
gent from the bottom and work in an upwards direction. Rinse
from the top and work downwards.
Use with alternative water sources
This high-pressure washer will self prime and can draw water
from water tanks and natural water sources. It's IMPORTANT
that the water is clean and the BOSCH inlet filter is clear and
fitted to the machine.
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.
Submerge the 3 m hose in water to displace the air. Connect
the 3 m supply hose to the pressure washer ensuring that the
inlet strainer remains submerged in the water source.
Run the pressure washer with the gun disconnected until a
steady flow of water appears from the high pressure hose.
Stop if this has this has not been achieved within 25 seconds
and check all the connections. Switch off and connect the
gun, lance and nozzle to operate.
It is important to ensure that all hose and coupling connec-
tions are of good quality, air tight and that all washers are in
good condition and correctly seated in place. Failure to do so
may affect the self priming performance.
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.
