Avoid danger of injury through recoil forces:

Ensure that you have a ﬁrm footing when operating the spray gun.

Only hold the spray gun brieﬂy in any one position.

Depending on the high-voltage of the spray electrode and the ﬂow rate at spray pressures

can produce an electrostatic charge in the equipment.These can cause sparks and ﬂames

upon discharge.

Ensure that the unit is always earthed.

Earth the work pieces to be coated.

Ensure that all persons inside the working area are earthed, e.g. that they are wearing

derivable shoes.

2.2.4 CLEANING

2.2.5 HANDLING HAZARDOUS LIQUIDS,VARNISHES AND PAINTS

When preparing or working with paint and when cleaning the unit, follow the working

instructions of the manufacturer of the paints, solvents and cleaning agents being

used.

Take the speciﬁed protective measures, in particular wear safety goggles, protective

clothing and gloves, as well as hand protection cream if necessary.

Use a mask or breathing apparatus if necessary.

For sufﬁcient health and environmental safety: Operate the unit in a spray booth or on

a spraying wall with the ventilation (extraction) switched on.

Wear suitable protective clothing when working with hot materials.

De-energize the unit electrically.

Disconnect the pneumatic supply line.

Relieve the pressure from the unit.

Ensure that the ﬂash point of the cleaning agent is at least 15K above the ambient tem-

perature. Otherwise, the cleaning works shall be carried out at forced ventilated clea-

ning place.

To clean, use only solvent-soaked cloths and brushes. The cleaning process mustn´t

damage parts of the spray gun, it mustn´t be an abrasive procedure.

Parts of spray gun mustn´t submerged or soaked into solvent.

Non-ignitable cleaning liquids shall be preferred.

A suitable solvent for cleaning the spray gun depends on the part of the gun and on the

material that needs to be removed. It´s recommended to use only non-polar solvents

to prevent a conductive residue on critical components. If it´s necessary to use polar

solvents to clean the spray gun components, all residue must be removed by using a

nonconductive non-polar solvent.

All electrical components cannot be cleaned or soaked in any solvents.

An explosive gas/air mixture forms in closed containers.

When cleaning units with solvents, never spray into a closed container.

For cleaning liquids only electrically leading containers may be used.

The containers must be earthed.
