SAFETY REGULATIONS

Grounding of equipment (for ammable application
materials)

Due to the speed of the ow of the liquid at the high spraying

pressure, then under certain circumstances an electro-static charge

may originate in the equipment. When discharging, this may result
in the occurrence of sparks or ames. Therefore, the devices must
be grounded when spraying ammable materials. For connection of
the grounding, see commissioning.

Using the automatic gun

Never put hands or ngers in front of the gun. During assembly

or dismantling of the nozzle, when cleaning or pausing the work,
be careful and make sure that the gun is always secured against

activation to prevent any consequent injury.

Injury to operators

Injury caused by the application material can be very serious. In

the case of injury, immediately contact a doctor and advise which

material caused the injury.

Protection during use

To maintain and handle the application materials, and when cleaning

the equipment, follow the instructions from the manufacturer’s of
these materials. To protect the skin, respiratory system and eyes, use

protective working items, respirators, protective masks, breathing

devices, protective glasses, protective creams, etc.).

Pressure resistance

Keep the maximum working pressure of the application material

and working values for the compressed air - for recommended values,

see technical parameters.

Connecting hose

Angular adapters enable to connect the control air hose with an

outside diameter of 6.0mm and the sprayed air with the outside
diameter 8.0mm without special clamping elements. The angular
adjustable threading for the connection of the NH hose is tted by
cam tightening nut M14x1.5 for the safe and complete connection of
the hose with the diameter 6.0x4.0mm.

Workplace

For spraying and handling ammable liquids, the respective

standards are valid. Premises and rooms in which the work with

painting substances is carried out must be indicated and marked

with respect to the class of ammability pursuant to valid standards
and regulations.

If spray guns are used and operated in other countries, local

standards and regulations apply.

EQUIPMENT DESCRIPTION

» The EcoGun 648 automatic spray gun is designed for the application

of liquids by pressure supply (painting substances, glues, etc.).

The gun can be divided into three functional parts:

» The jet system consists of a nozzle, stainless jet with insert and

closing needle. The nozzle system creates a spraying image. The

needle and the nozzle are manually sealed to ensure complete

tightness when closing the output of the applied material. There is

special insert on the nozzle that enables complete tightness of the

nozzle with a lower tightening force.

» The front part of the mechanical part of the gun consists of a

stainless distribution cube of the applied material with the
tightening of the needle against the escape of pressure supplied

material. The outlet of the material is tted with a G1/8“ cap.

The outlet enables to easily clean the connection channel or for
the circulation of material and enables to connect two applied

materials. The circulation of the NH is not included in the delivery.

» The applied material is supplied from the source (transport

pump, pressure reservoir or central distribution of the

material) under pressure into the gun.

» The rear part of the mechanical part of the gun consists of a

Duralumin body with a pneumatic cylinder for opening (closing)

the nozzle system with any regulation of the lift of the needle for
setting the lift, regulation of wing air for setting the form of the

stream (round, oval), variable holder with the hole for clamping
to the manipulator with a diameter of 10 mm. The opening of the

outlet of the applied materials and the spraying air is ensured by

the pneumatic cylinder with the piston in the body of the gun.

» The spraying air (A) is regulated by the regulator of the

compressed air and closed (opened by the lift of the gun
piston).

» The control air (C) is separately controlled by a three-way

electromagnetic valve. The gun is controlled by the supply of
control air in front of the piston. Closing is by discharging the
air in front of the piston into the atmosphere.

» the piston into the atmosphere.
» The wing air (K) is controlled by mechanical regulation of

CAUTION

All workers assigned to operation and maintenance of the device must be

provably acquainted with the safety regulations and with the device operation

and maintenance manual!
