tive must be certain that the operator is fa-
miliar with the appliance and its

cohol or medications lead to a higher
safety risk while operating the machine.

must always be present when the appli-
ance is being operated, in order to be
able to shut off the appliance in emer-
gencies and to summon help if needed.
– The local and relevant accident preven-
tion directives as well as other, general-
ly applicable safety, health and work
related regulations are to be observed.

pliance while it is in flawless condition.
– Safety features on the appliance and
the spray unit must never be removed,
modified to made inoperable.
– Only use hose lines, spray units and ac-
cessories approved for the maximum
working pressure of the appliance.
– Hoses, pipes and connected accesso-
ries must be in good condition and in-
stalled properly.
– The application should not be operated
in explosive environments.
– If the appliance is used in hazardous ar-
eas (e.g. filling stations) the corre-

– Modifications of the set operating over
pressure on the appliance may only be
performed if previously agreed with the
operator of the spray unit.

spray pipe can throw you off-balance.
You may fall. The spray jet can fly off
and cause damage to persons. Search
a secure place to stand and hold the
gun firmly. Never hold on tightly to the
lever of the hand spray gun.
– Risk of falling! Take precautions when
working on a scaffold, so that the person
does not fall from the scaffold due to the
recoil force generated by the appliance.
– For manual work with a spray gun, the
nozzle diameter must be selected so
that the recoil force in the longitudinal
axis does not exceed 250 N during
max. operating pressure. If the recoil
force 150 N, the spray gun must be
equipped with a body support as per
European standard prEN 1829. With re-
coil forces that exceed 250 N, the noz-
zle must be guided mechanically.+
– The recoil forces may be different if you
are using angular spray devices.
– Always monitor the displays during op-
eration. If the displayed values are not
correct, switch the appliance off imme-
diately and remediate the cause of the
malfunction.

listed in the specifications.
– Any type of non-adherence as well as
resulting injuries to humans and dam-

of the operator. Failure to observe
these warnings may result in injuries or
death of the operating personnel.
