Starting

Electrical Safety
Warning! Switch off, remove plug from mains
before adjusting, cleaning or if cable is cut,
damaged or entangled.

Your machine is double insulated for safety and requires no
earth connection. The operating voltage is 230 V AC, 50 Hz
(for non-EU countries 220 V, 240 V as applicable).
For increased electrical safety use a Residual Current Device
(RCD) with a tripping current of not more than 30 mA. Always
check your RCD every time you use it.
The supply cables must be inspected for signs of damage at
regular intervals and may only be used if in perfect condition.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in order
to avoid a safety hazard.
Only use approved extension cables.

WARNING! Inadequate extension cables can
be dangerous. Extension cable, plug and socket
must be of watertight construction and intended 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 1.5mm2 to a max. cable length
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 connected
through the plug to the earth cable of your supply network
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 attached
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 authorised
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 socket
elsewhere.
Products sold in AUS and NZ only: Use a residual current device
(RCD) with a rated residual current of 30 mA or less.

Operation

► To prevent damage to the appliance, do not allow it to
operate dry.

Starting

supply and machine.
Connect the product to the mains supply ensuring that the
mains switch is in the off position.
Open water tap.
Press the safety lock (back button on the gun handle) to release
the trigger. Fully press the trigger until there is a constant
flow of water to clear the air from the machine and water
supply hose. Release trigger. Press the safety lock (front button
on the gun handle).
Turn button on main switch. Point the power gun downwards.
Press the trigger safety lock to release the trigger. Fully press
the trigger.

Autostop function

The machine is designed to switch off the motor when the trigger

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 machine
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.

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.

Recommended cleaning method

Step 1: Attach the fan nozzle and remove the heavy dirt.
Step 2: Attach the foam bottle and spray on the detergent
sparingly.
Step 3: Rinse off the loosened dirt and detergent with the fan
nozzle.
Note: When cleaning vertical surfaces, apply the detergent
from bottom to top. When rinsing off, work from top to bottom.

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 IMPORTANT
that the water filter is in clean condition when inserting
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
– 3m 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 seconds.
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 connections.
As soon as water flows out of the high-pressure
hose, switch the power washer off and connect the spray gun
and 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 provided)
to the tank outlet, open the tap to allow the water to displace
all the air in the hose and then connect to the pressure washer.
