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
Troubleshooting

Problems with TSS (Total Stop System) device Contact your Bosch Service Centre
Pressure pulsating Air in the inlet water supply hose/pump
Inadequate water supply
Water filter blocked
Water supply hoses squeezed
High pressure hose too long
F 016 L81 121 | (18.2.15)
This enables the pressure washer to draw water up to 0.5 m abo-
ve the water level in the source in approximately 15 seconds.
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 provi-
ded) 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.
Corrective Action
Connect plug
Use another socket
Replace fuse
Try without extension cable
Allow to cool for 15 minutes
Wait for pump/water supply hose/accessory to thaw
Replace fuse
Check that mains voltage corresponds to specifications
on the model tag
Allow to cool for 15 minutes
Change to a mains supply higher than the pressure
washer amp consumption
Clean nozzle
Check that the voltage of the mains power supply line is
the same as that on the plate
Check characteristics of extension cable
Contact your Bosch Service Centre
Allow pressure washer to run with open spray handle and
nozzle at low pressure until regular working pressure is
obtained
Check that the water supply corresponds to specifica-
tions. The minimum specification for the water supply ho-
se is 1/2" or 13 mm diameter
Clean water filter
Straighten out kinked water supply hoses
Remove high pressure extension hose. Retry (extension
hose max. 7 m)
