1. DESIGNATED USE
BINKS airless pumps are used exclusively to output and apply spray material. Any materials can
be sprayed, if they are approved by spray material manufacturers for use with airless spraying
equipment. These include:
 Water-thinnable lacquers and paints
 Solvent-based lacquers and paints
 Base paints and primers
 Micaceous iron ore
 Zinc-rich paints
 Epoxy and polyurethane paints
 Oils
 Liquid synthetic materials
 Wax-based underbody sealant materials
 Low-solvent and solvent-free spray material
Please observe the working guidelines and safety instructions supplied by the spray material
manufacturer.
You should avoid using abrasive, granular spray material. Such spray material can
cause heavy wear and tear on the valves and packing sets of the material pump, and
on the nozzles used on the airless gun.

Comments on figure 1
The pneumatic motor (1) drives the BINKS airless pump. An airflow controller in the pneumatic
drive applies compressed air alternately to the pneumatic motor piston. This sets the butt plate
moving upwards and downwards.
The pneumatic motor is flange-mounted directly to the spray material pump (4). A moving axle
connects the pneumatic drive butt plate to the double piston of the spray material pump.
The ascending stroke of the double piston draws in the material through the suction system (5) and
the foot valve of the material pump. At the same time, the material spray, which is already in the
spray material pump above the double piston, is ejected through a check valve into the high pres-
sure filter (11).
The descending stroke of the double piston closes the foot valve and the spray material which has
been drawn in, is forced through a plunger valve into the space above the double piston. At the
same time, the spray material which is already there is ejected into the high pressure filter.
If the airless gun take-off is not operative, counter pressure will build up in the spray material line.
The pump will stop. Remove spray material from the airless gun and the BINKS airless pump will
start up again.
The area of the motor piston is greater than the area of the material piston. This difference in area
causes the pressure to intensify. With an area ratio of 60/1, for example, a working pressure of 1
bar at the pneumatic drive will be intensified to a working pressure of 60 bar at the spray material
pump.
The lubrication chamber (10) physically separates the pneumatic drive from the material pump.
The lubrication chamber is filled with lubricant (Order Code 0114-014871 for waterborne paint,
Order Code 0114-009433 for solvent paint). The release agent cleans the double piston of the
spray material pump and lubricates the packing and the moving axle.
The volume of air and thus the delivered volume of spray material is regulated by the working
pressure at the compressed air control valve (7). The compressed air control valve is equipped
with an excess pressure safety valve, which is triggered if the maximum working pressure at the
pneumatic motor is exceeded.
The material pump can draw in spray material in two ways.
Direct suction:
This involves immersing the suction system in the spray material.
Suction through a flexible suction system:
This involves connecting the spray material pump to a flexible suction system. The free end of the
suction system is inserted into the tank containing the spray material.

Edition 06/08

The extracted spray material is filtered through the high pressure filter (standard filter on HP 4/32:
type 03 - order-no. 0110-009130), before being driven out through the spray hose and the airless
gun. We recommend the following filter cartridges for the various types of spray material:
Filter size Nozzle Spray material
M 200 less than 0.3 mm colourless lacquer
M 150 greater than 0.3 mm surfacer, filler, red lead
M 100 greater than 0.3 mm surfacer, filler, red lead
M 70 greater than 0.5 mm micaceous iron ore, red lead
M 50 greater than 0.6 mm emulsion, loaded spray mate-
rial
Do not use a filter cartridge for fibre-loaded spray material!

Packings:
The lifetime and the maintenance rate of a pump depend crucially on the right packing. The pack-
ing for solvent and waterbased paint are different.
For the use of high viscosity or high corrosion materials we recommend high-strength packing.
Depending on the field of application there are different packings for solvent and waterbased mate-
rials.
Standard packing:
Upper packing:
Mixed standard packing (for solvent paint materials) Part-no.: 0114-014513
Consisting of: PTFE/Leather packing
Standard packing (for waterborne paint materials) Part-no.: 0114-014559

Note:
To the high-strength packings graphite is added to the PTFE. This improves the lubrication quali-
ties. High strength packings are not recommended for bright finish paint. Graphite can change the
colour of the finish paint.
If you need special packings without graphite admixture please contact your dealer.
Our pumps are supplied fitted with mixed packing for the application of solvent paint.

4. SAFETY
As well as the operating instructions and the applicable legal and other mandatory regula-
tions relevant to accident prevention in the country of use and at the place of use, you
must also observe the recognised special engineering regulations governing safe and pro-
fessional working practices.
4.1 PRINCIPLE OF OPERATION; INTENDED USE
1. BINKS airless spraying equipment has been built to comply with state-of-the-art standards and
recognised safety rules. Nevertheless, its use may constitute a risk to life and limb for the user
or for third parties, or cause damage to the BINKS airless pump and other assets.
2. The BINKS airless pump must only be used in technically perfect condition in accordance with
the regulations and the instructions set out in the operating instructions and only by safety-
conscious persons fully aware of the risks involved. Any malfunctions, especially those affect-
ing safety, must be rectified immediately. The spray material line must not be dragged across
sharp-edged objects and must always be checked before use to ensure that it is in perfect
condition.
3. BINKS airless pumps are designed exclusively for the designated use stated in Section 1. Us-
ing them for purposes other than those mentioned is considered contrary to the intended use.
The manufacturer/supplier cannot be held liable for any damage resulting from such use. The
user alone must bear the risk.
4. The manufacturer is not liable for any unauthorised modifications or repairs made to the
BINKS airless pump.
5. In accordance with the professional association directives governing spray equipment , ZH
1/406, paint spraying equipment should be checked by experts on request, or at least every
12 months, to ensure that there is no risk involved in its continued operation. If the units are
idle, the examination can be delayed until the next period of operation. The operator is obliged
to register the equipment for testing and to keep written records of the results of such testing.
4.2 SAFE WORKING CONDITIONS
1. The requirements of the (German) accident prevention and safety regulation “Working with
surface coating compounds” (VBG 23) and the (German) directives governing spray equip-
ment (ZH 1/406) and static electricity (ZH 1/200) provided by the professional associations,
must be observed.
2. Every person using a BINKS airless pump must have read and understood the operating in-
structions, in particular the chapter on “Safety”.
3. If work is to be carried out in enclosed areas, effective, technical ventilation must be provided.
4. Use only those spray material lines and airless guns that are designed for use at the relevant
maximum permitted working pressure of the spray material pump.
5. Be careful that there are no sources of ignition in the vicinity, for example, an open fire, sparks,
glowing wires, hot surfaces, burning cigarettes, etc. There must be a distance of at

Edition 06/08
11
least 5 m between the spray jet outlet and any possible source of ignition (the spray mist is ig-
nitable and there is a risk of fire or explosion).
6. The spray material leaves the nozzle under pressure. Do not direct the spray jet towards peo-
ple or animals, as this could cause injuries. If the skin is broken and comes into contact with
paint, lacquer or solvent, there is a risk of infection. Consult a doctor immediately to obtain pro-
fessional, expert treatment. Tell the doctor which spray material or solvent is involved. Present
the safety data sheet.
7. Be aware that working with sprays may produce vapours which can damage your health (see
information on the safety data sheet and the tins of material). You must therefore use a per-
sonal breathing equipment, as indicated by the spray material manufacturer. Keep children
and all people right away from the work area.
8. Keep the BINKS airless pump in a safe place to which children and unauthorised persons do
not have access. Make sure that unauthorised personnel (and children in particular) cannot
start up the BINKS airless pump.
9. Store the BINKS airless pump in a dry place.
10. Use only original BINKS accessories and original BINKS replacement parts.
11. Repair work must only be carried out by authorised specialised companies or by ITW
You can obtain the addresses of specialised companies from ITW or from your
specialised dealer.
12. When repairing and mounting the pump it is necessary that all connections are clean and
mounted correctly.
Before re-starting the pump the correct resistance (1 MΩ) must be measured.
The resistance has to be determined between foot valve and upper top point of the pump.
13. You must be careful when carrying out spraying work, not to direct the jet towards the
BINKS airless pump unit.
14. Dispose of cleaning and spraying material waste in accordance with the information provided
by the respective spray material and solvent manufacturers.
15. If work is interrupted, to change the nozzle, for example, lock the safety lever on the airless
gun. Release pressure from the system.

Edition 06/08
12
4.3 PARTICULAR DANGER SPOTS
1. The flow of material escaping from the airless gun is under great pressure and thus has a
powerful cutting effect.
You must therefore never point the airless gun at yourself or any other person, animal
or plant. Never touch the spray jet with your fingers or hand, or hold them in front of
the airless gun.
Note:
If the cutting effect of the flow of material causes injury seek medical advice immediately.
Tell the doctor which spray material (paint) and/or solvent (thinners) was involved and provide
the relevant information from the manufacturer as per the safety data sheet (supplier, his
phone number, the material number).
2. The escaping spray material generates recoil power. You must therefore always hold the air-
less gun securely and make sure that you have a well-balanced stance.
3. In enclosed systems, or systems which are under pressure, where aluminium or galvanised
parts come into contact with the liquid, there can be dangerous chemical reactions if 1.1.1 tri-
chloroethane, methylene chloride or other solvents containing halogenated chlorinated hydro-
carbons, are used.
If you use the named solvents or paints which contain these solvents, we recommend that you
contact the spray material manufacturer or ITW Oberflächentechnik.
4. If there are malfunctions or obstructions, you must immediately shut off the compressed air
supply at the ball valve. Disconnect the unit from the compressed air system, operate the air-
less gun and open the high pressure filter relief valve before removing the airless gun or the
hose.
5. To prevent static charging from causing a fire or an explosion, the equipment must be properly
grounded (the pump, the material tank, the object to be coated). If using materials with a flash
point under 21°C of ignition group G1-G3, there must be an additional conductive connection
between the material tank and the pump (potential equalisation cable). The material tank must
always be made of metal.
6. Prevent spray back into a closed tank, as an ignitable gas/air mixture will build up. Take par-
ticular care with materials with a flash point less than 21°C
7. The A-weighted sound level of pumps may exceed 85 dB (A).
Local conditions may dictate a higher noise level, which could cause noise deafness. If this is the
situation, operating personnel must be protected by suitable protective equipment or safety meas-
ures.

Edition 06/08
13
5. START-UP AND OPERATION
5.1 GROUNDING THE BINKS AIRLESS PUMP
To prevent static charging igniting the flammable spray material, the BINKS airless
pump must be grounded in accordance with professional association regulation
ZH 1/200 (Germany), “Static Electricity”, before it is started up. A grounding cable is
included in the supply schedule.
1. Grounding wire has to be mounted on the grounding terminal of the high pressure filter or (if
pump is used without HP-filter) on the middle section of the pump.
2. Connect the other end of the grounding cable to a suitable grounding device (e.g. grounding
bar).
5.2 PREPARING TO START UP THE BINKS AIRLESS PUMP
Proceed as follows:
1. Check that the lubrication chamber is full. To do this, open the screw plug on the filler neck of
the lubrication chamber. If necessary, top up the lubricant (Order Code for solvent paint: 0114-
009433, for waterborne paint: 0114-014871) and close the screw plug again.
2. Select a suitable filter cartridge using the table in section 2, Brief Description and insert it into
to the high pressure filter.
3. Attach a suitable hose to the spray material line to the spray material outlet connection piece
on the high pressure filter.
The spray material lines in the BINKS supply programme are identified on the screw
fitting with the maximum permitted working pressure and the bursting pressure. The
lesser value, the maximum permitted working pressure, must be greater than the
maximum permitted working pressure of the spray material pump (see 3, Technical
Data).
4. Connect the airless gun designed at least for the maximum permitted working pressure of the
spray material pump, to the fluid hose.
We recommend for Airless: BINKS Airless spray gun HAP 50 with max. pressure 500 bar or
BINKS Airless spray gun Airless 1 with max. pressure 420 bar.
We recommend for Aircombi: BINKS Aircombi spray gun AA 4000 with max. pressure
275 bar or BINKS Aircombi spray gun DSG-2000 with max. pressure 250 bar.
5. Make sure that the ball valve on the pneumatic drive is closed.
6. Connect the compressed air supply at the compressed air supply connection piece.
7. The airless pump is equipped with an air maintenance unit, consisting of filter, pressure regu-
lator and fog lubricator. The air maintenance unit is intended for cleaning compressed air for
workshop purposes from liquid and solid contamination, for pressure regulation and for provid-
ing a fine oil spray for lubrication of cylinders, valves etc.
Set the amount of oil (drops per minute) on the dosing screw as required during operation.
The number of drops can be seen in the sight-glass.

Edition 06/08
14
The filter cleans the compressed air from water condensate, scale, rust particles etc.
Drain off the water condensate at regular intervals and clean the sintered filter if it is dirty.
Before putting the pressure line into operation, relieve the filter regulator by fully unscrewing
the regulating screw. Thereafter rotate the regulating screw clockwise until the pressure gauge
on the filter regulator indicates the required pressure (please consider the min. and the max.
data - see section 3 Technical Data).
5.3 RINSING THE BINKS AIRLESS PUMP
Wear eye protection
Every BINKS airless pump is tested with water during final inspection and thoroughly rinsed with a
non-gumming preservative oil. With this rinsing process, it is possible that the residual moisture of
water emulsion will be left in the pump.
Before the unit is started up for the first time, a suitable solvent must be used to thoroughly rinse
out the remains of the preservative fluid and the unavoidable impurities introduced during equip-
ment assembly.
Proceed as follows:
1. Prepare the BINKS airless pump for start-up in accordance with section 5.2.
2. Close the high pressure filter relief valve.
3. Immerse the spray material pump or the suction system in the tank of solvent.
4. Insert the high pressure filter return pipe into the tank of solvent. Open the high pressure filter
relief valve.
5. Open the ball valve of the air supply and set the compressed air control valve on the pressure
regulator to approximately 1 bar. The spray material pump or the suction system now draws in
the solvent. The solvent runs back to the tank through the high pressure filter, the high pres-
sure filter relief valve and the return pipe.
6. Point the airless gun into the tank. Unlock the safety lever on the airless gun, operate the air-
less gun trigger and close the high pressure relief valve. The solvent will now flow through the
high pressure filter, the spray material line and the airless gun, back into the tank.
The time of rinsing depends on the length of the material lines and the solubility of the spray
material. We recommend a short reflush with "fresh" solvent.
7. Release the airless gun take-off.
8. Slowly increase the pressure at the compressed air control valve of the pressure reducer to
maximum working pressure (see section 3, Technical Data), while checking and testing that all
lines and screw and plug caps are tightly sealed. If there are any leaks in the system, shut
down the BINKS airless pump immediately. Only re-start the BINKS airless pump once you
have repaired the leak.
9. Reduce the pressure at the compressed air control valve of the pressure reducer again and
close the ball valve.

Edition 06/08
15
10. Make sure that the return pipe is still directed into the solvent tank. Carefully open the high
pressure filter relief valve to reduce the pressure in the spray material pump and in the high
pressure filter.
11. Point the airless gun into the tank of solvent and operate the trigger, to reduce any pressure
which may still exist in the spray material line and in the airless gun.
If working with waterborne spray material, the BINKS airless pump must again be
thoroughly rinsed with water before it is started up.
5.4 PREPARING AND ADJUSTING THE SPRAY MATERIAL
To be able to work without trouble and obtain a perfect surface, special care must be taken in pre-
paring and adjusting the lacquers and paints (please contact spray material manufacturer).
Before starting to spray, it may be necessary to use the solvent prescribed by the manufacturer to
thin the spray material. Add thinners until, after a good stir, the spray material runs easily off the
stick used for stirring. To prevent any uncertainty, we recommend that you use a dip measuring
cup, where the run-out time of the spray material indicates whether the spray material is still too
thick and therefore whether it is necessary to add more thinners. According to experience, the flow
time for lacquers and paints is 18 to 22 DIN4 sec. and for effect lacquer and coating filler materials
25 to 50 DIN4 sec. These figures relating to DIN EN ISO 2431 and have been established at a
temperature of 20°C. The lacquer and paint manufacturers generally state the best spraying con-
sistency for each of their products. If you use motor driven mixers, you must ensure that no air
bubbles form in the spray material.
To take a measurement, proceed as follows:
Immerse the measuring cup into the lacquer or paint which is ready for spraying until it is full to the
brim. To make the measurement, quickly take out the dip measuring cup and count how many
seconds it takes for the entire contents of the cup to run through the 4mm nozzle, i.e. up to the
time when you can establish the break-off point of the out-flowing paint. Count off the seconds on a
wristwatch, or time with a stopwatch. If, for example, a consistency of 19 DIN4 sec. is prescribed,
but the measurement is 24 DIN4 sec., you must add some more thinners and make the measure-
ment again.
We recommend that once you have used it, you clean the dip measuring cup immediately, so that
it can be used again for the next measurement.
Because two filters are used in the BINKS airless unit, a suction filter and the high pressure filter, it
is not necessary to filter the spray material before working with it.
If particularly high-quality coating work is involved, you can also use a gun filter from the BINKS
accessories range.
5.5 START-UP
1. Prepare the BINKS airless pump for start-up in accordance with section 5.2 and if necessary,
rinse in accordance with section 5.3.

Edition 06/08
16
2. Close the high pressure filter relief valve.
3. Immerse the spray material pump or the suction system in the spray material to be used for
working.
4. Place the high pressure filter return pipe in the tank. Then open the high pressure filter relief
valve.
5. Open the ball valve for the compressed air supply and use the pressure regulator to set the
compressed air supply to 1 bar. The material spray pump will now draw in the spray material.
The spray material flows back into the tank through the high pressure filter, the high pressure
filter relief valve and the return pipe.
6. Point the airless gun into the tank. Unlock the safety lever on the airless gun. Operate the air-
less gun take-off and close the high pressure relief valve. The spray material will now flow
through the high pressure filter, the spray material line and the airless gun, back into the tank.
7. Release the airless gun take-off and set the working pressure at the pressure control valve of
the pressure reducer.3
Before carrying out any coating work, we recommend a test spray (e.g. on to paper or wood). Only
if the test gives you the desired result should you start to coat the actual object.
Make sure that the edges and the fringe areas of the object to be coated are also given an even
coating.
5.6 WORK STOPPAGES
 If working with 2-K spray material, you must note the given pot life and follow it
precisely. Within this time, the unit must be carefully cleaned and rinsed with the
recommended solvent. There must be no residue left in the spray material pump,
the high pressure filters or the airless gun.
 When work is stopped, the safety lever of the airless gun must be locked.
For work stoppages of between 10 and 30 minutes, please proceed as follows:
Wear eye protection
1. Lock the safety lever on the airless gun.
2. Shut off the compressed air supply by closing the ball valve.
3. Briefly open the high pressure relief valve, taking care that the return pipe is not pointed at
other people or at yourself, until the pressure has reduced. Then close the high pressure relief
valve again.
4. Clean the outside of the airless nozzle from spray material residue.

Edition 06/08
17
6. SHUT-DOWN
Once work is completed, the BINKS airless unit must be thoroughly cleaned. Under no
circumstances must you allow paint residue to dry out in the unit. To clean the airless
unit, use a solvent appropriate to the spray material.
Wear eye protection
1. Close the ball valve for the compressed air supply.
2. Make sure that the return pipe is still directed into the spray material tank. Carefully open the
high pressure filter relief valve to reduce the pressure in the spray material pump and in the
high pressure filter.
3. Point the airless gun into the tank of spray material and operate the take-off to reduce any
pressure which may still exist in the spray material line and in the airless gun.
4. Lock the safety lever on the airless gun.
5. Remove the spray material pump or suction system from the spray material.
7. CLEANING YOUR BINKS UNIT
In no case spray material or solvent should soak into the ground or the sewage system
Wear eye protection
1. Clean the pump and the suction system from the outside. Immerse the spray material pump or
the suction system in the tank of solvent.
2. Clean the fluid tip / tip system as described in the service bulletin of the spray gun. We recom-
mend to soak the fluid tip in solvent.
3. Unlock the safety lever of the airless gun without fluid tip but with mounted tip system or tip
guard. Operate the gun. Close the high pressure filter relief valve. Set the incoming air pressure
to max. 2 bars and open slowly the ball valve. Let the solvent runs through the system so that
the spraying material could rinse out.
4. Let the solvent runs through the system for a couple of minutes until the solvent runs clear
through the airless gun. Close the ball valve and lock the safety lever of the gun
5. Clean the airless gun from the outside and check the filter on the handle (if mounted).
6. Clean the filter element of the high pressure filter.
7. Clean the filter on suction pipe.
8. We recommend to keep the equipment filled with liquid.
We recommend to preserve the BINKS airless equipment if it is not used for a longer period of
time. Please rinse the complete system with silicon-free oil as described in section 5.3.

9. INSTRUCTION MANUAL
Depending on the type of application and the place of installation, the operator must use the oper-
ating instructions to provide more details on the safe operation of the BINKS airless pump, in the
form of an instruction manual in the language of the workforce. This instruction manual is to kept in
a suitable location at the place of work and the workforce informed of its whereabouts. The work-
force should comply with the instructions contained in this instruction manual.
10. COMPULSORY TESTING
In accordance with the professional association directives governing spray equipment
ZH 1/406, paint spraying equipment should be checked by an expert on request, or at least every
12 months, to ensure that there is no risk involved in its continued operation. If the units are idle,
the examination can be delayed until the next period of operation. The operator is obliged to regis-
ter the equipment for testing and to keep written records of the results of such testing.
An expert is someone whose professional training and experience has given him adequate knowl-
edge and understanding of jet stream units and who is sufficiently acquainted with the relevant
national health and safety and work and accident prevention regulations, directives and generally
recognised technical regulations, that he is able to assess whether jet stream units are safe to op-
erate.
The employer (operator) must make sure that test results for each jet stream unit are kept as a
written record and that this is retained until the next text. We provide a blank "Test record for
spraying equipment" form for this purpose. Please make as many copies of this as you need.
Furthermore, you must ensure that this test document is available at the place where the jet
stream unit is in use. A copy of the test record or a test plaque is sufficient for this.
But we also ask you to enter the test document, date and expert in the “Test Document” table.
