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.
If in doubt contact a qualified electrician or the nearest Bosch
Service Centre.
WARNING! Inadequate extension cables can
be dangerous. Extension cable, plug and sock-
et must be of watertight construction and in-
tended for outdoor use.
Cable connections should be kept dry and off the ground.
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.
Products sold in GB only: Your product is fitted with an
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.
To prevent damage to the appliance, do not allow it to operate
dry.
Operation
Starting

mains switch is in the off position.
Open water tap.
Press the safety lock (back button on the gun handle) to re-
lease the trigger. Fully press the trigger until there is a con-
stant flow of water to clear the air from the machine and water

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.
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: Loosening dirt
Remove the nozzle from the lance to give a low pressure flow
and spray on the detergent 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.
