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.
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.

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 the roto nozzle to clean motor vehicles.
Do not tamper with or adjust the safety valve setting.

Working advice for cleaning with detergents

f

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.

Recommended cleaning method

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 a vertical surface spray off dirt/deter-

gent from the bottom and work in an upwards direction. Rinse

from the top and work downwards.
