5. Remove from base the 10 gallon pail pro­
vided. Wipe clean its interior and potiT into it
material stirred and thinned to the proper spray-
consistency or place a smaller container of ma­
terial inside the 10 gallon pail. Stir material
thoroughly making sure there is no heavy pigment
concentration or cake formed on the bottom of the
container* The pigments must be well dispersed to
prevent them from clogging the fluid intake
strainer 205-306 v4ien the pump is initially lower­
ed into the container of material.
ROTBs For a small container, such as a one
gallon can, the material intake strainer must be
removed in order to get the lower pump housing and
the agitator propeller into the container.
6. Check the position of foot valve feet in
relation to the perforated plate 162-363 of pump
fluid intake strainer. When the plate and screen
are held in position by the retaining ring 162-416,
the feet of foot valve body must contact and sup­
port the perforated plate 162-363 as shown in
Fig. 3*
NOTE: If desired, the 100 mesh screen in
strainer 205-306 can be removed and replaced -with
the extra, more coarse 50 mesh screen 162-746 sup­
plied. Refer to Fig. 3- This 50 mesh screen
should be used with spray tips having larger ori­
fice openings.
7* Lower pump into material. If unit with
manual elevator, unhook hanger to lower. If unit
with pneumatle elevator, lower by disconnecting
air hose 160-023 from elevator air line fitting*
Refer to Fig. 1*
NOTE; The speed at which unit is elevated^
bv air, is set at factory. If adjustment is
necessary, loosen lock nut of air restrictor
valve 203-743 and turn restrictor screw clockwise
to decrease or cqunterolo^kwi^e to increase * Lock
screw in place with lock nut when adjustment is
completed. Air.restrictor valve 203-743 is locat­
ed atop elevator tube. Refer to Fig. 1.
8,
If unit includes a filter kit 205-523 or
a filter kit 205-523 and a surge taniT 205-4767
refer to illustrated instructions in separate
Form
306-696
for easy conversion of manifold
205-485 to a filter or a filter-surge chaaiber. .
9- Insert delivery end of material dispens­
ing hose into a xiraste container. Start pump by
opening CM-OFF punro air petcock 202-338 and set­
ting regulator
205-360
at 30 p.s.i. Refer Fig. I.
Allow pimip to operate until all traces of rust
inhibiting oil, with vrfiich pump was treated, is
removed. Stop pump and discard material pumped.
NOTE: If accessories have been added to
-unit for two gun operation, open material shutoff
valves 205-583 and insert ends of both hoses Into
-waste container before starting pump. Refer to
Fig. 2.
10. Connect swivel 204-940, at-tached to free
end of material dispensing hose, to spray gun
inlet.
OPERATION
IMPORTANT NOTES
1. For most satisfactory operating condi­
tions, locate pump and material so that they will
not be subjected to temperatures below 65° F.
2. Do no.t attempt to spray materials con­
taining hea-gy fillers, dirt or other coarse
particles> Coarse grind, coagulated, con-taminat-
ed and skinned materials that will not pass freely
through the openings in sice
of
screen or filters
being used, without clogging, can not be satis­
factorily sprayed. Due to the extremely small
orifice diameter in spray tip through vdiich ma­
terial must be forced under pressure, it is very
Impor-bant that particle's which could plug this
orifice are not present in the material to be
sprayed.

. Daily, before starting to spray, remove
and clean filter, if used, of spray gun.
Paily. with air pressure shut off and
relieved, remove and clean screen in air line
s-fcrainer 204-999 (accessory), if used. Add
light oil to screen cavity in strainer nut. See
Fig. 4.

.. Dally or more often if experience indi­
cates necessary. WITH PUMP DEACTIVATED AMD FILTER
DUMP VALVE OPEN TO RELIEVE MATERIAL PRESSURE, re­
move and clean filter cartridge or screen, if
used. Refer to Fig. 1.

. Dally, remove and clean screen in pump
material intake strainer 205-306. When replacing,
check to be sure that plate
162-363
is in contact
with feet of pwmp foot -valve. Refer to Fig.

7* When thinning material;cleaning filters,
screen, tips, etc.; changing types of material to
be sprayed or flushing unit; be sure to tise CLEAN
solvent of a type recommended b.y manufacturer of
material being sprayed. Use of the wrong solvent
may cause jelling or separation, of material oompo-
ents which could cause clogging of strainer,
filter and spray gun tip. DO NOT USE COMMON GUN
CLEANER.
