Operation; High Pressure Operation - Kärcher HD 25/15-4 Manual

Suck in water from vessel
DANGER
Never suck water from a drinking water
container.
When fitted with the appropriate accesso-
ries, this high-pressure cleaner can draw in
surface water, e.g. from water butts or
ponds (max. suction height 0.5 m).
DANGER
Never draw in fluids containing solvents or
undiluted acids and solvents! This includes
petrol, paint thinner and heating oil. The
spray mist is highly inflammable, explosive
and poisonous. Do not use acetone, undi-
luted acids and solvents, as they corrode
the materials used on the appliance.
 The standard water connection is not suit-
able for sucking in water; hence use
Kärcher suction hose (minimum diameter
approx. 1 inch) with filter (accessory).
Dearating the appliance
 Open the water supply.
 Unscrew the nozzle.
 Press the lever on the hand spray gun.
 Switch on the appliance and let it run
until the water exiting from the spray
pipe is bubble-free.
 Switch off the appliance and fit the noz-
zle again.

Operation

DANGER
– Risk of injury! Never use the appliance
without the spray lance attached.
Check and ensure proper fitting of the
spray lance prior to each use. The
screw connection of the spray lance
must be finger-tight.
– If the appliance is used in hazardous ar-
eas (e.g. filling stations) the corre-
sponding safety regulations must be
observed.
– Place the appliance on firm, even sur-
face.
CAUTION
Clean engines only at places with correspond-
ing oil separators (environmental safety).

Turning on the Appliance

 Unlock the safety lock at the hand-
spray gun by pressing it.
 Press the lever on the hand spray gun.

High pressure operation

DANGER
Long hours of using the appliance can
cause circulation problems in the hands on
account of vibrations.
It is not possible to specify a generally valid
operation time, since this depends on sev-
eral factors:
– Proneness to blood circulation deficien-
cies (cold, numb fingers).
– Low ambient temperature. Wear warm
gloves to protect hands.
– A firm grip impedes blood circulation.
– Continuous operation is worse than an
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
WARNING
The water jet that is emitted from the high-
pressure nozzle results in a repulsion pow-
er acting on the hand spray gun. Make sure
that you have a firm footing and are also
holding the hand spray gun and spray lance
firmly.

ing nozzles:.
