Noise/Vibration Information

Sound emission values determined according to
EN 60335-2-79.
Typically the A-weighted noise levels of the
product are:
Sound pressure level
Sound power level
Uncertainty K
Wear hearing protection!
Vibration total values a (triax vector sum) and
h
uncertainty K determined according to
EN 60335-2-79:
Vibration emission value a

Uncertainty K
Connecting to the water supply
(see figure F)
Note: Rated output pressure can only be achieved, if the flow
rate at the water input is sufficient. The flow rate is sufficient
if a 10 litre bucket can be filled in less than 1 minute.
CAUTION: Permanent operation with lack of water at the wa-
ter input can damage the pump.
NOTE: For a sufficient water supply use a short hose with a di-
ameter not thinner than 1/2" (13 mm). Hoses longer than
10 m should have a diameter of 3/4" (19 mm). Open the wa-
ter tap completely. All connections must be tight. Clean the
water filters periodically (see chapter Maintenance).
– It is recommended to use always an external water filter
(accessory). Check water filter for tight assembly.
– If necessary, screw on an hose adapter (not supplied with
the machine).
– Connect a suitable water hose, best with 1/2" (13 mm) or
3/4" (19 mm) diameter.
– Open the water tap completely and check all connections
for tightness.
Connecting to the mains (see figure G)
NOTE: Rated output pressure is only available, if the machine
is connected to a stable mains voltage. Using a long connec-
tion cable with a thin wire cross section, an uncoiled cable
drum, operating other machines concurrently at the same cir-
cuit or voltage fluctuations outside accessible tolerances im-
pede motor starting or result in low output pressure.
Bleeding high-pressure washer and
hoses (see figure G)
NOTE: Bleed the unit each time the water hose is connected
to the water tab according the following procedure:
Leave the main switch at OFF (0) position.
Disconnect the lance from the gun.

– As soon the trigger of the gun is operated, air and water ex-
its noisily. Hold the trigger until water exits steadily from
the gun. Release the trigger.
– Reconnect the lance.
– Switch on the machine for operation.
– Press the safety release and operate the trigger of the gun.
Use with alternative water sources
(see figure I)
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 both BOSCH inlet filter and exter-
nal filter are clear and fitted to the machine (see chapter Main-
tenance).
Open tanks/containers and natural
water sources (see figure I)
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 25 – 50
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.
Run the pressure washer with the lance disconnected until a
steady flow of water appears from the high pressure hose.
Stop if this has not been achieved within 25 – 50 seconds and
check all the connections. Switch off and connect the lance
and nozzle to operate.
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).
