SAFETY REGULATIONS
Earthing of the Equipment
Due to ow rate of the liquid at the high spraying pressure the
electro-static charge may be developed on the spraying gun under
certain circumstances. It may result in sparks of ames due to
discharging. To prevent this phenomena the spraying device must be
earthed. In addition the conductive connection (potential equalizing
cable) must be installed between the high-pressure device and the
gun during processing of the materials with the ignition point below
21°C (NITRO etc.).
Resistance to Pressure
All elements forming part of the high-pressure section of the
automatic spraying gun comply by their operating pressure with the
maximum pressure specied by the technical parameters.
Manipulation with High-Pressure Valve
The high-pressure gun operates with very high pressures.
Therefore never put your hand and/or ngers before the gun and
never focus the gun to the body. During assembly or disassembly of
the nozzle, resp. during cleaning or during any interruption of the
work proceed very carefully and secure the gun to prevent accidental
start (disconnection of the control air). This is to prevent accidental
start of the gun and possible subsequent injury.
Injury of Operator
The injury caused by the high-pressure liquid may be very serious.
In case of injury immediately seek the doctor and notify him/her on
type of material causing the injury.
Personal Protection at Work
During spraying and handling with the application materials, as
well as during cleaning of the equipment adhere to instructions of
manufacturers of the materials; use suitable personal protective
equipments (clothes, gloves, respirators, protection masks, resp.
breathing devices, protecting creams etc.) to protect the skin and
respiration tracts.
Although very small amount of fog is generated during the highpressure spraying, the spraying procedure cannot be considered for
the fog-free one. Even if the air contains very low number of the
particles, it is necessary to exhaust the solvent vapours, which are
especially dangerous.
Equipment Cleaning
During cleaning of the equipment with the ammable liquids it is
necessary to prevent the back-spraying into the closed vessel, as the
liquid stream can produce the explosive mixture of the gas and air.

EcoGun 651
Workplace
Relevant standards apply to spraying and handling with the
ammable liquids. Regarding the ammability class of the coating
materials the areas and rooms, where the coating materials are
used, must be marked and modied in compliance with applicable
standards and regulations.
When the guns are used and operated in other countries, the
local standards and regulations apply.
EQUIPMENT DESCRIPTION
The automatic high-pressure spraying gun EcoGun 651 is designed
to application of the liquids by pressure supply. The gun consists
from two functional parts:
» Front part of the gun mechanical sections consists from stainless
coating substance (hereinafter referred to as NH) distribution
box with needle sealing to prevent leak of the pressure supplied
NH. The connecting angle-adjustable tting for the NH is tted
with the M14x1.5 thread. The second inlet of the NH is blinded
by the G1/8“ plug; when the plug is replaced with the NH
circulation line (not part of the supply), the NH circulation is
enabled (used for heavier NH etc.).
» The back part of the gun mechanical section consists from the
Duralumin body with pneumatic cylinder for opening (closing) of
the needle valve. The valve is opened by supply of the pressure
control air 5 bars before the piston by the 6 mm diameter hose.
Outlet of the pressure NH is closed by release of the air before
the piston to the atmosphere. The control air is separately
controlled by means of the three-way electro-magnetic valve.
In addition, the gun is tted with the holder with 10 mm hole for
xing to the handling device.
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!
