Sucking water from the water tank
 When fitted with the appropriate accessories, this
high-pressure cleaner can suck water from vessel/
pool.
 The maximum suction height is 0.5 meters.
DANGER
Health hazard! Never pump water from a potable water
container.
Risk of explosion and poisoning! Never suck in liquids
which contain solvents like lacquer thinner, petrol, oil or
unfiltered water. The solvent spray is highly flammable,
explosive and toxic.

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 tightened by hand.
DANGER
 Place the appliance on the firm surface.
 The high-pressure cleaner must not be used by chil-
dren. (Risk of accident on account of improper use
of the appliance).
 The high-pressure spray generates high levels of
noise when the appliance is in use. Risk of hearing
impairment. Always use proper ear-protection aids
while working with the appliance.
 The water jet coming out of the high-pressure noz-
zle causes the gun to recoil. 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 distance of 30 cm. Otherwise, the
high-pressure spray can cause damage to the vehi-
cle tyre/tyre valve. Damaged vehicle tyres are a
source of danger.

immediately and thoroughly using water and seek med-
ical attention immediately. The same applies if deter-
gents are swallowed.
