SAFETY REGULATIONS
Appropriate standards apply to spraying and handling with
ammable liquids. Areas and rooms, where coating materials
are handled with, shall be identied and adapted regarding the
ammability of the coating materials in compliance with applicable
standards and regulations.
In case the spraying guns are used and operated in other countries,
then relevant national standards and regulations apply.
Electrostatic charge (electricity) can occur under certain
circumstances due to ow of air and liquids. During discharge it may
result in sparking and/or aming.
To prevent such situation it is necessary to use hoses with
guaranteed electrostatic drop-in particularly for coating materials
with ignition point below 21°C (nitro-, acetone coating materials
etc.) and some coating materials of 2nd ammability class preheated
to higher temperature - it is necessary to ensure certied hoses with
such identication.
Vibrations and noise
The vibration level transferred to hands does not exceed maximum
allowed value acc. to NV 272/2011 Coll.
The noise level depends on size of nozzle system and on input
pressure value, which ranges from 80 to 90 dB(A). Allowed permitted
nose level acc. to act no. 272/2011 Coll. is 85 dB(A) and thus it is
necessary to use hearing protection equipments.
Work With gun
SThe spraying gun operates with pressure to 4 bar, air pressure
- recommended 1,8-2,5 bar. Do not focus the gun to yourself, other
persons or animals. Solvents and thinners may cause chemical burn.
During nozzle assembly, disassembly, cleaning or each interruption
of work proceed very carefully and ensure locking of the gun to
prevent eventual starting. Thus you may prevent the injury. Before
all repair works the gun shall be disconnected from pressure air
supply.
CAUTION
Do not use the basic variants of the guns for solvents from chlorohydrocarbon
family, as e.g. 1.1.1. trichlorethan and metylchloride may cause chemical
reaction with aluminium and with galvanized, resp. zinc-coated parts and thus
create explosive mixture with eventual explosion effect.
CAUTION
All persons authorised to operation ad maintenance of the equipment must be
provably acquainted with the safety regulations and with the operation and
maintenance manual for the equipment.

Personal Protection during Work
During spraying and handling with the application materials
and during cleaning of the equipment follow instructions and
recommendation of manufacturers of particular materials. Use
suitable work protection aids to protect skin, respiratory tract and
eyes (clothes, gloves, respirators protecting masks, resp. breathing
apparatuses, goggles, protection creams etc.).
EQUIPMENT USE AND DESCRIPTION
EcoGun 119 air spraying gun is a gun allowing connection of
top vessel (gravity supply of coating material).
Atomising system with decreased pressure of atomising air at the
gun jet mouth, similar to RP system.
The gun features very good grip and balance in hand, as well
as easy less wearisome handling. Assembly threads of connecting
elements are glued with suitable sealing compound (LOCTITE 542).
The spraying gun can handle all types of coating materials,
which are intended to application by spraying, and whose chemical
composition does not disturb the spraying gun components.
Recommended distance of nozzle mouth to the sprayed surface
(spraying distance) depends on side of nozzle assembly and type of
coating material, it ranges from 150 to 190 mm.
Semi-automatic needle seal ensures maximum period
of maintenance-free and reliable operation of the seal.
Mechanical re-tightening of the needle seal enables increased
interval between service repairs. The system joints advantages
of automatic and mechanical design of the needle seal retightening.
ecogun 119 sPraying gun
This type of the gun can handle following types of the coating
materials:
Solvent-based – synthetic, nitro, acetone, polyurethane, epoxy
and acrylic, primers, llers and nish varnishes
Water-based – acrylic, silicate, silicone and polyurethane
substances
and other application materials of similar properties.
