<<Range of Application of this equipment>>

Equipment covered by this Instruction Manual are electrostatic hand spray guns, Model
LP6000W/S/M which are to be used for manual paint spraying in a spray booth equipped with a
power exhaust.

This equipment is a manually operated spray gun used to apply paint to a grounded object.
If there is any question or if these instructions are not perfectly understandable, please consult

our distributor or contact a representative of ECCO Finishing AB for clarification.
The use of this equipment for any purpose other than that for which it is intended could cause

serious consequences.

<<CAUTIONS When Using the Painting Equipment>>

1. The object to be painted should be grounded without fail. Always use a conductive hanger.
Periodical cleaning should be performed so as to maintain conductivity.

2. All conductors or thinner container in the coating booth should be grounded. The structure of
the floor should have a preventive structure for static charge of 1M ohm or less.

3. The applicable area for the working floor of the open structure-coating booth is a rectangle
shaped area with a side of 1.5m (opening width + both sides) and the other side of 2.5m
(closer side of the opening part). This entire area should have a static charge preventive
structure of 1 M ohm. The area should be clean.

4. Operators should use bare hands or ware non-conductive gloves during operation.

5. Operators should ware the anti-electrostatic protective footwear.

6. Ventilation should properly be ensured during coating.

7. Fluid pressure and air pressure should be zero, and power switch of the control panel should
be turned off before the nozzle is washed. Do not touch nozzles during high voltage is
charged.

8. Do not use the metal brush for washing nozzles.

9. Do not immerse guns and hoses in the washing solvent.

10. Hoses should be hanged from the ceiling or side walls instead of being trailed on the floor.

11. Duct fan of the coating booth should always be cleaned to maintain cleanliness.

12. Distance between the nozzle end and the object to be painted should be 150mm or more.

13. Fire extinguisher should always be provided in the vicinity of the work site for in case of fire
caused by electrostatic.

14. Operator should take a safety-operational lesson regarding the applicable coating
equipment before operation.

1. Better maneuverability

The pattern adjusting valve at left side of gun body allows quick and easy adjustment. Lighter
weight and triggering provides less fatigue of workers.

2. High productivity

In addition to conventional electrostatic spray nozzles, newly developed flat spray nozzles are
featured to provide a more improved wrap-around effect resulting in higher transfer efficiency
and, the resultant material saving.

3. Easier maintenance

Most of the parts required for service are modularized which make them easier to replace. Also
the need of troublesome adjustment and re-tightening of packings is eliminated.

4. Longer parts life

Super hard alloy needle with a hardened material seat valve and self-sealing, spring loaded U
packings assure long working life.

5. High quality coating

Wide angle multi-step injection by flat spray nozzles can achieve beautiful finishes on flat
surfaces, particularly in metallic coating.

6. Wider range of material selection

Besides ordinary hi- solids paint, almost all types of conductive paints including metallic and
water-borne paints can be applied from an isolated material supply system.

7. Highly secured safety

Cascade built in the gun body means fewer areas being charged by high voltage and
substantially improved safety. High voltage control unit EXC LP has over-current protection
and resistance limitation, quick shut-off of high voltage electronic switching and buzzer alarm
system. These features ensure safety protection for the operator.

Safety is drastically enhanced because the area to which high voltage is applied is reduced by
incorporating a high voltage generator into the gun.

The standard system composition with LP6000W/S/M guns are illustrated on Fig. 1 (page 3).

1. Connection of air supply

Connect air supply hose to air regulator on the control unit. (G 1/4 fitting)

2. Connection of grounding wire
Securely connect a grounding wire to control unit. Phillips screwdriver is required for this
operation.

Grounding wire for control unit should be 3.5mm2 or larger, and be connected to any place
prepared with Class 1 grounding (grounding resistance under 10Ω.)

Installation

CAUTION

- 16 -

3. Connection of the power cable to the spray gun

After cleaning the metal connector at the end of power cable fixed to gun with clean cloth,
connect it securely to output terminal (OUTPUT) on the control unit.

Attach the cable to the gun by tightening it manually.
After the attachment, use a stopper for locking. Do not tighten excessively when the
attachment position does not seem to be correct. In such cases, attach the cable so that the
surface of the stopper may closely contact to the hexagonal plain part while loosening the nut.

Fix the cable and the air hose with the insulation lock at the position 70 to 80cm from the gun.
At this time, allowance is required for the cable so as not to apply load to the root part of the
connector.

When the cable, air hose, paint hose or the like are held together with a tape, a small allowance
is needed so as not to apply the tensile force to the cable. If a tension is applied to the cable
during operation, this might lead to breakage of the cable. See “6. CAUTIONS WHEN BANDING
L. V. CABLE WITH HOSES” for more details.

CAUTION

- 17 -

4. Connection of air hose

Connect one end of the air hose to the nipple at rear side of the spray gun (next to power cable)
and the other end to the air exit on the control unit and tighten (G 1/4 fitting). It is recommended
that the spanner of 17mm be used.

*The case in which two hoses are used.

Be sure to use two spanners when the air hose or paint hose is attached to the gun in order to
prevent applying excessive force to the gun. In addition, do not allow the spanner to contact the
cable connector at the time of attaching or removing.

Effective atomization can be obtained by using an air hose of 3/8 inch when the air hose is longer
than 10m. Attach a joint bushing to have a screw opening of G 3/8.

5. Connection of paint hose

One end of the paint hose should be connected to the nipple at the front side and the lower end of
the gun grip (front side of the cable), and the other end of the paint hose is attached to the pump
system.

CAUTION

CAUTION

- 18 -

6. CAUTIONS WHEN BANDING L. V. CABLE WITH HOSES

(1) In order to extend the life of the cable, follow the instructions on the cautions of banding the

cable with the hoses.

1) Do not band the connection cable at the length shorter than 70cm from the grip portion of
the gun.

2) When banding the cable, there should be enough allowance to the cable relative to the air

and paint hose so as not to cause excessive bending or tension to the cable when the gun
is faced upward, downward, left or right.

3) When banding the cable at a length longer than 70 cm from the grip portion of the gun,

make an enough allowance at 5cm intervals using resin bands (insulation lock) vinyl tape.
Do not wind the vinyl tape of wide-spiral tape continuously, because the wound part
becomes the rod-like shape and this might cause the breakage of the cable or hose.

(2) Do not operate the gun or do not band the cable so as not to cause excessive bending or

tensile to the cable, air hose and paint hose during painting. If this is not observed, breakage
might occur due to degradation of strength.

(3) Please pay attention not to step on the cable. Breakage might occur if you step on the cable

placed on the metal pallet.

(4) Do not wind on the cable the vinyl tape or the like continuously for reinforcement or

contamination-prevention, especially portion close to the gun connector. Breakage might

occur if you step on the cable placed on the metal pallet.
(5) Do not immerse cable into solvent or paint. It will shorten the cable life.
(6) Wipe off the solvent on the surface or air-blowing should be performed after washing of the

cable.
(7) Do not use metal cable ties, they will build a capacitance charge and discharge to nearest

ground.

CAUTION

7. Assembly of nozzle with gun

1) Fix and tighten together the nozzle joint and material nozzle.

2) Put charging electrode into the material nozzle and fix nozzle joint to extension, tightening
it with the spanner (Hex. 10).

3) Put the air cap in the holding nut and fix them to the barrel and tighten by hand.
The fixing nut and air cap are to be put together as an assembly.

As it is made of resin, excessive tightening might lead to the damage to the inner screw of the
nozzle mount joint. Pay attention when attaching and removing.

Air cap can be slightly tightened by fingers. If it is tightened too much, paint nozzle might loosen
when changing the direction of the air cap. This might lead to coating failure.

Materials of air caps or nozzles are resin which can withstand the solvent. However, immersion
for long time might deteriorate the original performance. Wash them with solvent and dry
sufficiently with air blow before storage.

The Electrostatic spray nozzle is very precisely
made. Special cautions must be taken to keep it
clean and free from damage.

In order to maintain safety of operation and good condition for the equipment, please note the
following issues for care not only before and during but after operation.

 Securely ground the control unit.

It is one of the most basic provisions for safety to ground the control unit, as grounding for the
spray gun is also accomplished by grounding the control unit.

The object to be coated must be grounded.
The grounding resistance for the object should not exceed 1M ohm. (Resistance
measurement voltage to be 500V minimum) Objects can be normally grounded through
hangers and conveyors but excessive dried paint on hangers may degrade their conductivity
and allow electrostatic accumulation of a charge on the part which sometimes leads to
discharge a spark and a possible resultant fire. To prevent these dangers, hangers should be
cleaned regularly to remove dried paint that can act as an insulator.

 All conductive articles in the spray booth must be grounded.

In the spray booth, high voltage may ionize the air around the coating equipment, which has
a danger of electrostatic accumulation on any conductive materials that are not grounded,
resulting in a possibility of sparking. Apparatuses such as coating equipment mounting
stand and safety guards made of metal must be securely grounded. Also do not place any
paint containers or tools which are unnecessary in the booth. Even outside the booth, solvent
containers should be grounded if they are close to or near to booth entrance.

 Handle coating equipment with bare hands.

Though the gun grip is grounded through the cable and control unit, wearing of
non-conductive gloves on hands means insulation of human body where electrostatic is
accumulated, creating a danger of electric shock when any part of the body touches a
grounded article. If wearing of gloves is necessary for any reason, the glove should have a
hole so that bare skin of the hand can contact the gun grip.

 Be sure to wear leather soled or anti-electrostatic shoes.

As indicated above, air in the spray booth is ionized by electrostatic coating and can
accumulate energy in the human body which will discharge to ground. Operators and other
people who intend to get in the booth are to be neighboring area should put on
anti-electrostatic shoes for safety. Such shoes should be also regularly cleaned not to allow
excessive accumulation of paint or other dirt. Naturally, the floor of working area should be
conductive.

 The working floor should have static charge preventive structure. The close

structure-painting booth should have this preventive structure for the entire floor; the open
structure-coating booth should have this preventive structure for the area having both sides
of 1.5m and the front side of 2.5m. These area should have a static charge preventive
structure of 1 M ohm, and should be clean.

 Whenever it is necessary to clean or wash nozzles, switch off the power to the control unit

and touch the electrode in the gun head to any ground to discharge any residual high voltage
in the system during the nozzle cleaning.

7

Safety control

WARNING

- 21 -

 Never use a metal brush to clean nozzles.

Nozzles are vital parts of the coating equipment and may be easily damaged by the use of
metal brushes, which can cause distorted paint atomization. When cleaning is required, use
a bamboo brush provided in the tool kit supplied with the equipment. Also be cautious of the
electrode pin on the nozzle. It is sharp and can penetrate your skin during nozzle cleaning.

 Do not dip the entire gun, cable or hoses in solvent.

Electrostatic spray equipment may be easily damaged by soaking in solvent.

 Do not drag cables and hoses on the floor. They should be suspended by hanging from

ceiling or wall as much as possible. If conductive paint is being dispensed, hang the hoses
away from ground with insulated “stand offs”.

 Keep the inside of booth and the exhaust system (ducts, fan, etc. ) clean by regular cleaning.

If they are contaminated with paint or other dirt, they increase the possibility of an accidental
fire in the booth.

 Fully drain water from air transformers, air compressors, etc.

Existence of water in the air line may cause poor coating appearance and may energize the
safety circuit causing the buzzer alarm to sound.

 Keep a distance between the nozzle head and object surface at least 150mm. Normally

electrostatic spray guns are designed to decrease the hi-voltage potential automatically when
the spray gun approaches a grounded item. In cases where an insulated paint supply pump
is being used(for lower electric resistance paint like metallic paints, woodworking paints,
emulsion paint, etc. ), the guns potential is not decreased to the level of the pumps potential,
causing the possibility of a capacitance discharge and the resultant spark. Cares must be
taken to keep sufficient distance between the gun and ground at all times. Part swinging on
the conveyor can rapidly create this potential problem.

 When using an isolation stand, keep it at least 500mm from other surrounding articles, being

sure it is protected from personnel with fencing. Provisions must be made to ground the
system after power is switched off. If in doubt concerning the proper safety grounding of a
fluid supply system, consult your distributor or ECCO Finishing AB for assistance.

 An approved fire extinguisher must be available within 10 meters of the spray area.
 Do not pull the trigger directing the gun head to any part of your body or to any other person.

Even if the equipment is out of service and turned off, there is a possibility of paint injection
because of remaining pressure. Always close material adjusting valve of the spray gun
whenever work is stopped.

 Whenever re-starting the operation, be sure there is no air/paint leakage or loosened

connectors in any part of the system.

 Follow the present laws and regulations for usage and installation of this equipment.
 Follow the laws and regulations of the country in which the equipment is used.

WARNING

- 22 -

1. Checking high voltage generator
(1) Open the air valve and adjust the air pressure on the regulator to 0.3 to 0.4MPa to supply
air to the system. Be sure that there is no air leakage from any hose connection.
(2) Holding gun grip, switch on power to control unit. Green pilot lamp should be on. At this
point, no high voltage is at the gun head.
(3) Pull the gun trigger. When air flows through the nozzle, the air flow switch incorporated in
the control unit energizes high voltage to the system. The high voltage indicator (red lamp) will
be on . High voltage is present at the gun head as long as the red lamp is on. (High voltage is
not generated if the switch at the gun grip is off.)

Switch off the control unit as soon as the equipment check is complete.

2. Paint adjustment
In this system, almost all synthetic resin paints can be sprayed with electrostatic energy and
there is no need to adjust the paint. Sometimes higher electrostatic effect can be obtained by
adjusting the solvent blend. There are some low electric resistance paints that cannot achieve
good electrostatic results. Check the resistance value of your paint using a resistance meter.
Good electrostatic results normally can be achieved by adjusting the resistance value to 15 to
70M ohm. If under 15MÙ, there will be some electrostatic effect, but too much paint will
bounce back in the direction of the gun and operator. This will necessitate higher exhaust
velocity and reduced transfer efficiency.

 Electrostatic effect can be confirmed by spraying from the front side of a 20 to 30mm dia.

Steel pipe. It the paint wraps to the back side of the pipe, proper electrostatic effect is
confirmed.

 No electrostatic results are expected when metallic, water-borne or other extremely low

resistance conductive paints are being used. In the case where high voltage is transmitted to
those types of paints, the high voltage shut-off circuit in the control unit may shut the system
down energizing the high voltage with buzzer alarm. Reset can be accomplished by turning
the power switch off and on.

 Always use paint and solvent which have an ignition point at least 5°C higher than room

temperature

 If there is any doubt, question or uncertainty in the suitability of your paint for this equipment,

consult our distributor or ECCO Finishing AB for assistance.

Checking before operation

CAUTION

CAUTION

- 23 -

1. Preparation for operation
(1) Fill the paint supply system.

The viscosity of the paint normally used for this equipment ranges in 9 to 30sec/FC #4, but not

limited to viscosity. Consideration must me given to the type of paint and solvent, configuration of
the part to be coated, required film thickness and, other conditions. It is recommended that the
electric resistance value of the paint be measured before filling the supply system.

(2) Start the material delivery system to supply paint to the spray gun.

Be sure the supply pump is operated under low pressure (approx. 0. 1Mpa) using the air

regulator so that the pump will begin to cycle slowly to siphon the material and to prime the
system. Increase pump pressure gradually until the material regulator at pump outlet shows 0.2
to 0. 3 Mpa. If more precise fluid control is necessary or if the fluid flow pulsates, consider adding
a fluid regulator to the system between the material supply system and the electrostatic gun.

Confirm again that the control unit power is off.

(3) Inject the paint from the gun tip.

Turn off atomization air and pull the trigger to start flowing paint from the spray gun. Since there

may be air entrapped in the supply line continue t o flow paint until all remaining air pockets in
paint hose are removed. Paint output can be increased by turning adjuster valve at rear right
side of gun body counter-clockwise and stopped by fully turning it clockwise. When painting is
ceased, turn the valve fully clockwise to stop paint output, or curtail the pump pressure.

(4) Increase atomizing air gradually to observe the degree of atomization.

Adjust atomizing air pressure to 0.2 to 0.3 MPa and pull trigger to observe the degree of
atomization. Please understand that only enough atomization to break up the necessary paint
flow should be used. Excessive pressures will only accomplish increased over-spray and waste.
This atomizing air pressure should be adjusted to suit the nozzle and the requirements of the
process.
In addition, this gun uses inside airtight structure in order to prevent the paint come into gun body.
Small volumes of air always flow out from needle. Therefore it is not malfunction if there is sound
of airflow from needle.

(5) The spray pattern can be widened by turning the pattern width adjusting valve at the left rear of

the gun body counter-clockwise and narrowed by turning it clockwise.

Make sure that air is not leaking when returning the connection of the air hose and the trigger to
the original position. When air is discharged with the power supply on, a high voltage is
generated whether it is operating or not.

Operation

CAUTION

WARNING

- 24 -

2. Starting operation
(1) Switch on the power to control unit. When trigger is pulled, red lamp is illuminated to indicate

high voltage is applied at the gun head. High voltage is not generated when switch at gun grip is
off.

 Before switching on the control unit, confirm again that the unit is securely grounded through

a grounding wire.

 Never wear gloves without a hole in the palm to handle the spray gun. Never wear rubber

soled shoes during operation of an electrostatic gun. The gun grip is at zero potential if the
control unit is grounded and there is no danger of electric shock if the gun grip is held by a
bare hand.

(2) Start the painting operation. Adjust the voltage level on the control unit to suit conditions.

Adjustment range is 20 to 60kV.

 Before starting operation, check to see if the grounding resistance of the object to be coated

is under 1MΩ.

 Do not touch object to be coated with the metal part of the nozzle. Normally potential at the

nozzle is automatically lowered as it approaches any grounded object, but there is a slight
danger of sparking in a case of a rapid approach gun to ground.

 Do not touch the nozzle during high voltage is applied.

(3) When not painting, always switch off the power to the control unit.

 Never leave the spray gun alone while the power switch on the controller is on.
 If paint of low electric resistance (2MΩ or lower), is to be used, the paint supply pump should

be installed on an insulated stand. In this case, high voltage is also present at the pump.
Never touch the pump when the high voltage is on. When necessary to service the supply
equipment be sure to switch off the hi voltage by turning off the switch on the controller, then
be sure to ground the system as there is a good possibility that residual high voltage will be
retained.

3. Finishing operation (When re-starting within 24 hours is expected)
(1) Switch off power to control unit by one hand, and holding the spray gun in the other hand. Do

not place the gun on the floor or on a work bench.
(2) Lower the atomizing air pressure to 0Mpa at the regulator.
(3) Lower the air pressure supplying the delivery system to 0MPa.
(4) Pull the spray gun trigger to release remaining fluid pressure.
(5) To discharge remaining voltage, carefully touch the nozzle electrode to ground keeping the

trigger open.

CAUTION

CAUTION

CAUTION

- 25 -

(6) Wipe off the nozzle and gun body and remove paint and dirt using solvent soaked cloth. To clean

a flat spray nozzle, remove its air guide and to clean the round spray nozzle remove its air cap.

 Whenever coating work is curtailed, close the material adjusting valve on the gun body to

prevent any chance of paint flow.

 To clean the nozzle and air cap, direct the gun head downward to prevent cleaning solvent

from finding a way inside the gun.

 After cleaning, do not immerse the gun, cable or hoses in solvent. This equipment should be

considered as an electric instrument. Continuous dipping in solvent may cause degradation
of the durability and will damage the equipment due to solvent penetration.

 If a two component paint or other chemically curing products are used, the same steps as

indicated in the next clause must be taken frequently depending on curing conditions.

4. Finishing operation (When re-starting within24 hours is not expected. )
(1) Switch off power to control unit.
(2) Lower atomizing air pressure to 0MPa.
(3) Take the suction pipe from the paint container.
(4) Lower the air pressure to the supply pump (approx. 0. 1PMa), allow the paint remaining in the

pump to bleed through the return.
(5) Pull gun trigger to reduce paint pressure remaining in hose and gun.
(6) Flush cleaning solvent through the system until the fluid passages are clear of paint.
(7) Pull gun trigger to reduce pressure from the cleaning solvent and to flush the gun and hose.
(8) Turn off air to the pump and release the remaining pressure from the gun.
(9) Wipe off nozzle and gun body using a solvent soaked cloth. Remove the nozzle from gun body

and clean the seating parts between the gun body and nozzle.

 The cleaning and flushing should be started at least 10 seconds after switching off the control

unit. It should be noted that over 90% of fire accidents in electrostatic systems occur during
cleaning and flushing. Be sure to switch off the control unit before cleaning. An approved fire
extinguisher should be available.

 Never wear gloves without a hole in the palm to handle the spray gun. Never wear rubber

soled shoes during operation of an electrostatic gun. The gun grip is at zero potential if the
control unit is grounded and there is no danger of electric shock if the gun grip is held by a
bare hand.

(10) For the disposing the waste solvent, recover and reuse the waste solvent by use of solvent

recovery system, or dispose them through the waste disposal company in accordance with lows

and regulations.

CAUTION

CAUTION

- 26 -

1. Spray gun
(1) Always keep spray gun clean. To clean the spray gun, do not dip the gun body into solvent. Hold

it your hand and wash it carefully using a soft brush or cloth and solvent.

Replace the gun cover before being heavily contaminated. High voltage is likely to leak through
paint attached to the cover especially in the case of using metallic or water-based paint. This
might lead to overcurrent or electrical shock to the operator. Do not use the cover for such
circumstances.

(2) Do not disassemble the gun except in the case of the need for repair and parts replacement.
(3) When there is no work, keep the gun hooked on the gun holder. Never forget to switch off the

control unit whenever gun is not in use.

(4) There are many plastic parts contained in the LP6000 spray gun for minimizing weight.

Although these parts are designed to have enough strength for normal use, care should be
taken that they do not fall on the floor.

(5) It is possible that the rear upper part of the gun body may become warm due to heat produced

by the cascade. This condition is perfectly normal and should be ignored.

2. Nozzles
(1) Whenever the finishing operation is completed, clean the nozzles thoroughly.
(2) Do not use metal wire or pins to clear clogging of the nozzle holes. To remove clogged holes,

dip the nozzle in solvent a few minutes, then clear with a dust gun using compressed air. Do
not use a metal brush to clean the nozzle.

(3) Nozzles should be cleaned often even during coating operation. Paint sticking to the nozzle

may cause a distorted pattern, effect atomization and electrostatic efficiency.

Nozzle is worn out as paint injection is performed.
Measure the output periodically. When the specified amount cannot be output, replace the
nozzle.

Nozzle is ultra-precision part. Do not drop it or apply any impact.
Damaged nozzle might be causes of deteriorated atomization of paint or pattern shape, and
result in paint failure.

Maintenance

CAUTION

CAUTION

CAUTION

- 27 -

3. Paint hose and power cable

(1) Hose and cable should be kept clean from paint accumulation.
(2) Use caution not to damage hoses and cables with heavy objects or vehicles.

Before any maintenance and/or service work, make sure that the power switch is turned off on
the control unit and the air/fluid pressure is released.

Any container used for cleaning solvent should be conductive and securely grounded.
