If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Only use approved extension cables.
WARNING! Inadequate extension cables can
be dangerous. Extension cable, plug and sock-
et must be of watertight construction and in-
tended for outdoor use.
Extension cords, cables, leads, reels should only be used if
they comply with EN 61242/IEC 61242 or
IEC 60884-2-7.
If you want to use an extension cable when operating your
product, only the following cable dimensions should be used:
– Nominal Conductor Area of 1.5mm
of 20m for a Cord Extension Set
The connections (plugs and sockets) should be kept dry and
off the ground.
It is recommended that this is accomplished by means of a
cord reel which keeps the socket at least 60 mm above the
ground.
Note: If an extension cable is used it must be earthed and con-
nected through the plug to the earth cable of your supply net-
work in accordance with prescribed safety regulations.
Refer to the instruction manual of the extension cord, lead,
reel manufacturer and your local wiring regulations.
If in doubt contact a qualified electrician or the nearest Bosch
Service Centre.
For products not sold in GB:
WARNING: For your safety, it is required that the plug at-
tached to the product 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.
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.
Products sold in AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.

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.
Do not tamper with or adjust the safety valve setting.
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.
By offering you an individualised range of cleaning and pre-
serving agents, Bosch guarantees troublefree operation of
the unit.

Step 1: Loosening dirt
Spray on detergent sparingly and allow to react for a short
time.
Step 2: Removing dirt
Spray off the loosened dirt with the high-pressure spray.
Note: When cleaning vertical surfaces, apply the detergent
from bottom to top. When rinsing off, work from top to bot-
tom.
