Water Connection; Suck In Water From Vessel; Operation - Kärcher HD 728 B Cage Originalbetriebsanleitung

Water connection

For connection values refer to technical
–
specifications
Warning
Observe regulations of water supplier.
According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply
without a system separator. Use a
suitable system separator manufactured by
KÄRCHER; or, as an alternative, a system
separator as per EN 12729 Type BA. Water
flowing through a system separator is con-
sidered non-drinkable.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!
 Connect the supply hose to the water
connection point of the machine and at
the water supply point (for e.g. a tap).
 Open the water supply.
Note
The supply hose is not included.

Suck in water from vessel

Danger
Never suck in water from a drinking water
container. Never suck in liquids which con-
tain solvents like lacquer thinner, petrol, oil
or unfiltered water. The sealings within the
device are not solvent resistant. The spray
mist of solvents is highly inflammable, ex-
plosive and poisonous.
 Connect suction hose (minimum diame-
ter 3/4") with filter (accessory) to the
water connection point.
 Set dosing value for detergent to "0".
 Remove air from appliance before oper-
ation.
Note
Do not use the Geka coupling (included in
delivery) for vacuuming! Not all connector
couplings are suitable for vacuuming
(pump sucks air and therefore does not
build up pressure).
16
Dearating the appliance
 Open the water supply.
 Start the engine according to the oper-
ating instructions of the engine manu-
facturer.
 To dearate the appliance, unscrew the
nozzle and allow the appliance to run
until the water exits in a bubble-free
state.
 Switch off the appliance and fit the noz-
zle again.
Danger
Place the appliance on firm surface.
–
The high pressure cleaner must not be
–
used by children. (Risk of accident on
account of improper use of the appli-
ance).
The high pressure spray generates high
–
levels of noise when the appliance is in
use. Risk of hearing impairment. Al-
ways use proper ear-protection aids
while working with the appliance.
The water jet coming out of the high
–
pressure nozzle causes the gun to re-
coil. Further, an angular spray pipe can
cause additional torque. Hence hold
the spray pipe and gun firmly.
Never direct the water jet on to persons,
–
animals, the appliance itself or electrical
components.
Vehicle tyres/ tyre valves may be
–
cleaned only with a minimum spray dis-
tance of 30 cm. Otherwise, the high
pressure spray can cause damage to
the vehicle tyre/ tyre valve. The discol-
ouring of the tyre is the fhe first sign of
damage. Damaged vehicle tyres are a
source of danger.
Do not spray materials contains asbes-
–
tos or other health-hazardous sub-
stances.
The operator must wear proper safety
–
gear to be protected against the water
sprays.
