GROUNDING THE BINKS PUMP
1.Clamp the grounding cable to the
terminal on the high pressure filter or
the air motor.
2. Connect the other end of the
grounding cable to a suitable grounding
device
PREPARING TO START UP THE BINKS
PUMP
Proceed as follows:
1.Check that the solvent cup (0115-
010059) is full to the level shown. If
necessary, add material to the solvent
cup. (Order part no. 0114-009433 for
solvent based paint, and part no. 0114-
014871 for waterborne paint.
2.Select a suitable filter element using the
table in this manual (page 10) and insert
it into to the high pressure filter (0115-
010326).
3.Attach a suitable fluid hose to the outlet
fitting (ref 9 p.8) on the high pressure
filter (0110-009130).
4.Connect the gun—designed at least for
the maximum permitted working
pressure of the pump—to the fluid
hose.
5.Make sure that the ball valve on the air
control assembly is closed.
6.Connect the compressed air supply to
the air inlet connection.
7.The pump is equipped with an air
pressure regulator (0115-010183).
Before putting the pressure line into
operation, relieve the pressure
regulator by fully unscrewing the
regulating screw. Thereafter rotate the
regulating screw clockwise until the
pressure gauge (0115-010192) on the
regulator indicates the required
pressure.
RINSING THE BINKS PUMP
Every BINKS 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 equipment
assembly.
Proceed as follows:
1.Prepare the BINKS pump for start-up as
shown above.
2.Fill the pail with a suitable cleaner or
solvent.
3.Place the Pump/lid on the pail, secure
with the 3 thumbscrews.
4.Open the high pressure ball valve (0114
-019091) on the fluid filter.
5.Open the air supply ball valve (and set
the air regulator (0115-010183) to
approximately 1 bar (14.5 psi). The
suction system now draws in the
solvent. The solvent runs back to the
solvent tank through the high pressure
filter (0110-009130) and the high
pressure ball valve (0114-019091).
6.Remove the spray tip from the gun and
point the gun into a suitable container.
Unlock the safety lever on the gun,
operate the gun and close the high
pressure ball valve. The solvent will now
flow through the high pressure filter,
the fluid hose and the gun, into the
container. 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 gun trigger.
8.Slowly increase the pressure at the
regulator to maximum working
pressure 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
pump immediately. Only re-start the
BINKS pump once you have repaired
the leak.
9.Reduce the air pressure at the air
regulator (0115-010183) again and
close the ball valve.
10.Make sure that the return flow hose
(0110-009103) is still directed into the
solvent tank. Carefully open the high
pressure ball valve (0114-019091) to
reduce the pressure in the fluid hose
and in the high pressure filter.
11.Point the gun into the tank of solvent
and operate the trigger, to reduce any
pressure which may still exist in the
fluid hose and in the gun.
START-UP
1.Prepare the BINKS pump for start-up as
shown above and if necessary, rinse
pump.
2.Place the Pump/lid on the pail, secure
with the 3 thumbscrews.
3.Open the high pressure ball valve (0114
-019091).
STARTUP AND OPERATION
CAUTION
If working with waterborne material, the
BINKS pump must again be thoroughly
rinsed with water before it is started up.
(Cont. on next page)
WARNING
The fluid hose supplied by BINKS is
identified with the maximum permitted
working pressure and the burst
pressure. Check that the lesser
v a l u e —t h e m a x i m u m w o r k i n g
pressure—i s greater than the
maximum permitted working pressure
of the pump.
WARNING
To prevent static charging igniting the
flammable spray material, the BINKS
pump must be grounded before it is
started up. A grounding cable is
included with the pump.
NOTE
The pump is equipped with an air
pressure safety valve (0114-014774)
set at 8 bar (116 psi).
WARNING

4.Open the ball valve for the compressed
air supply and use the pressure
regulator (0115-010183) to set the
compressed air supply to 1 bar (14.5
psi). The pump will now draw in the
spray material. The spray material flows
back into the tank through the high
pressure filter, the high pressure ball
valve and the return pipe.
5.Remove the spray tip from the gun and
point the gun into a suitable container.
Unlock the safety lever on the gun.
Operate the gun trigger and close the
high pressure ball valve (0114-019091).
The spray material will now flow
through the high pressure filter, the
fluid hose and the gun, back into the
container.
6.Release the gun trigger and set the
working pressure at the regulator.
WORK STOPPAGES
For work stoppages of between 10 and 30
minutes, please proceed as follows:
1.Lock the safety lever on the gun.
2.Shut off the compressed air supply by
closing the ball valve.
3.Briefly open the high pressure ball valve
(0114-019091) until the pressure has
reduced. Then close the high pressure
ball valve again.
4.Clean the outside of the spray nozzle
from spray material residue.
SHUT-DOWN
1.Close the ball valve for the compressed
air supply.
2.Carefully open the high pressure ball
valve (0114-019091) to reduce the
pressure in the pump and in the high
pressure filter.
3.Remove the spray tip from the gun.
4.Point the gun into a container and
operate the trigger to reduce any
pressure which may still exist in the
fluid hose and in the gun.
5.Lock the safety lever on the gun.
6.Remove the pump/lid from the pail.
CLEANING YOUR BINKS PUMP
1.Clean the pump from the outside. Clean
the pail and fill with cleaning solvent.
Replace the pump/lid.
2.Clean the fluid tip/tip system as
described in the service bulletin of the
spray gun. We recommend to soak the
fluid tip in solvent.
3.Unlock the safety lever of the gun
without fluid tip. Operate the gun. Close
the high pressure ball valve (0114-
01909). Set the air inlet pressure to 1
bar (14.5 psi) and slowly open the ball
valve. Let the solvent run through the
system so that the spraying material
can rinse out.
4.Let the solvent run through the system
for a couple of minutes until the solvent
runs clear through the gun. Close the
ball valve and lock the safety lever of
the gun.
5.Clean the 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 of the suction system.
8.We recommend keeping the pump
filled with liquid.
