Binks MODEL 2100 SIPHON SPRAy GUN – POINTERS ON CLEANING
When used with a cup, thinner or suitable
solvent should be siphoned through gun
by inserting tube in open container of
that liquid. Move trigger constantly to
thoroughly flush passageway and to clean
tip of needle.
CLEANING GUN USED WITH
PRESSURE TANK
Shut off the air supply to the tank and
release the pressure on the tank. Open
vent and loosen air nozzle. Hold a piece
of cloth, wadded in the hand over the air
nozzle and pull the trigger, the air will
back up through the fluid nozzle, and
force the fluid out of the hose into the
tank. Next put enough thinner into the
tank to wash the hose and gun thorough-
ly and spray this through the gun until it
is clean. Then blow out the fluid hose to
dry it and remove all traces of materials
by attaching it to the air line.
THINNER
Keep thinner level below packing.
It is extremely poor practice to place an
entire gun in thinner. When this is done,
the solvent dissolves the oil in the leath-
er packing and causes the gun to spit. It
is good practice to place the nozzle and
fluid connection in thinner. Vessel used
should be shallow enough to prevent
thinner from reaching packing.
Keep thinner
level below
packing
LUBRICATION
Daily oil fluid needle packing, air valve
packing, and trigger bearing screw.
Occasionally coat needle valve spring
with petroleum jelly. OIL ALL
WORKING PARTS EVERY DAY.
CONTROLLING THE FAN SPRAy: The
fan spray for an external mix nozzle set-
up is easily controlled by means of the
side port control (2). Turning this control
to the right, or clockwise, until it is
closed will give a round spray; turning it
to the left, or counter-clockwise, will
widen the spray into a fan shape of any
width desired. The direction of the fan
spray, either horizontal or vertical, is
obtained by turning the air nozzle to the
Thinner
desired position, then tightening the
retainer ring.
CONTROLLING THE FLUID
If a fluid pressure tank is used, the
amount of fluid can be controlled by reg-
ulating the pressure on the tank. The
amount of fluid can also be controlled by
means of the fluid control screw (17).
Turning this screw to the right, or clock-
wise, reduces the amount of fluid; to the
left, or counter-clockwise, increases the
amount of fluid.
FAULTy SPRAy
A faulty spray is caused by improper
cleaning or dried material around the
fluid nozzle tip or in the air nozzle. Soak
these parts in a solvent that will soften
the dried material and remove with a
brush or cloth.
Caution
!
Never use metal instruments to clean
the air or fluid nozzles. These parts
are carefully machined and any dam-
age to them will cause a faulty spray.
If either the air nozzle or fluid nozzle is
damaged, the part must be replaced
before a perfect spray can be obtained.
TO REPLACE THE FLUID PACKING:
Remove the fluid control screw (17),
spring (16) and needle. Then remove the
fluid packing nut (5) and take out the old
packings with a small stiff wire. Replace
with new packings (4) oiled lightly and
assemble in reverse order. To set pack-
ing, insert needle, tighten nut until the
needle begins to be too stiff for the
spring to move the needle. Then loosen
nut 1/2 to 3/4 turn.
CORRECTING AIR LEAK
THROUGH GUN
Air leaking through the gun is caused by
the valve stem assembly (22), not seating
properly against the valve body (8).
Remove the valve body (8) and valve
stem assembly (22). Thoroughly clean
parts and inspect for damage. Replace
worn or damaged parts and assemble in
reverse order.
CORRECTING AIR LEAK AROUND
AIR VALVE STEM
Air leaking around the air valve stem (22)
may be caused by worn packings (25) or
damaged air valve stem (22). Remove
trigger (6), packing nut (24) and pack-
ings (25). Clean extended portion of air
valve stem (22) and inspect for damage;
if stem is damaged, replace same as
above, insert new packings and assemble
in reverse order.
