FLG5 – Gravity Feed Spraygun

Important

Read and follow all instructions and Safety warnings before using this

equipment

Description

The FLG5 Gravity Spraygun is fitted with a 1.4 or 1.8mm Nozzle for topcoat

applications. Alternative 2.0mm Nozzle and Needles are available for primer use. The

FLG5 Gravity Feed Spraygun is approved to ATEX regulations 94/9/EC, protection

level; II 2 G X

SAFETY WARNINGS

Fire and explosion

Solvents and coating materials

can be highly flammable or

combustible when sprayed. ALWAYS

refer to the coating material suppliers

instructions and COSHH sheets

before using this equipment.

Users must comply with all local

and national codes of practice

and insurance company

requirements governing

ventilation, fire precautions, operation

and house-keeping of working areas.

This equipment, as supplied,

is NOT suitable for use with

Halogenated Hydrocarbons.

Static Electricity can be

generated by fluid and/or air

passing through hoses, by the

spraying process and by

cleaning non- conductive parts with

cloths. To prevent ignition sources from

static discharges, earth continuity must

be maintained to the spraygun and other

metallic equipment used. It is essential to

use conductive air and/or fluid hoses.

Personal Protective

Equipment

Toxic vapours – When sprayed,

certain materials may be

poisonous, create irritation or be

otherwise harmful to health.

Always read all labels and safety data

sheets for the material before spraying

and follow any recommendations. If In

Doubt, Contact Your Material

Supplier.

The use of respiratory protective

equipment is recommended at all

times. The type of equipment

must be compatible with the

material being sprayed.

Always wear eye protection

when spraying or cleaning the

spraygun.

Gloves must be worn when

spraying or cleaning the

equipment.

Training – Personnel should be given

adequate training in the safe use of

spraying equipment.

Misuse

Never aim a spraygun at any part of the

body.

Never exceed the max. recommended

safe working pressure for the equipment

The fitting of non-recommended or non-

original spares may create hazards.

Before cleaning or maintenance, all

pressure must be isolated and relieved

from the equipment.

The product should be cleaned using a

gun washing machine. However, this

equipment should not be left inside gun

washing machines for prolonged periods

of time.

Noise Levels

The A-weighted sound level of

sprayguns may exceed 85 dB

(A) depending on the set-up

being used. Details of actual

noise levels are available on request. It

is recommended that ear protection is

worn at all times when spraying.

Operating

Spray Equipment using high pressures

may be subject to recoil forces. Under

certain circumstances, such forces could

result in repetitive strain injury to the

operator.

Installation

Important: To ensure that this equipment

reaches you in first class condition,

protective coatings have been use. Flush

the equipment through with a suitable

solvent before use.

1. Attach air hose to connector (19).

Recommended hose size 8 mm bore.

The hose must be conductive and

electrical bond from the spraygun to

earth should be checked with an

ohmeter. A resistance of less than

106Ωis recommended.

2. Air supply should be filtered and

regulated.

Preventative Maintenance

1. Turn off air supply and relieve pressure

in the airline, or if using QD system,

disconnect from airline.

2. Empty coating material into a suitable

container and clean the gun and cup,

preferably in a gun wash machine.

3. IMPORTANT– the cup must not be

cleaned or rubbed with a dry cloth

or paper. It is possible to generate a

static charge, by rubbing, which if

discharged to an earthed object

could create an incendive spark and

cause solvent vapours to ignite.

Only use a dampened cloth or

antistatic wipes if additional

cleaning is required in a Hazardous

area.

4. Remove air cap (2) and clean. If any of

the holes in the cap are blocked with

coating material only use the Cleaning

Kit KK-4584 (see accessories) which

has the correct tools for this or a

toothpick to clean. Using any other tool

could damage the cap and produce

distorted spray patterns.

5. Ensure the tip of the nozzle is clean

and free from damage. Build up of

dried paint can distort the spray

pattern.

6. Lubrication – Trigger stud (24), needle

(16) and air valve spindle (13) should

be oiled each day.

Operation

1. Mix coating material to manufacturers

instructions

2. Turn needle adjusting screw (18)

counter-clockwise until first thread

shows

3. Turn pattern valve (10) counter-

clockwise to fully open

4. Adjust inlet air pressure to give 2.4 bar

(35 psi) at the gun inlet with the gun

triggered. (pressure gauge attachment

shown under Accessories is

recommended for this)

5. Test spray. If the finish is too dry reduce

airflow by reducing inlet pressure. If

finish is too wet reduce fluid flow by

turning needle screw (18) clockwise. If

atomisation is too coarse, increase inlet

air pressure. If too fine reduce inlet

pressure.

6. The pattern size can be reduced by

adjusting valve (10)

7. Hold gun perpendicular to surface being

sprayed. Arcing or tilting may result in

uneven coating.

8. The recommended spray distance is

150-200 mm (6”-8”).

9. Spray edges first. Overlap each stroke a

minimum of 50%. Move gun at a

constant speed.

10. Always turn off air supply and relieve

pressure when gun is not in use.
