Section I. OPERATING PROCEDURES
Operation of the Model 50-6609 paint spray out-
fit must be in accordance with instructions con-
tained in this chapter. Procedures for achieving the
type of operating indicated in the following para-
graphs are provided for operation under normal con-
ditions. For operation under unusual or extreme
conditions, refer to Section II.
2-2. Preparation for Starting.
Before starting the compressor assembly, you
should prepare it for operation in accordance with
the following paragraphs (Fig. 2-1):
a. Perform daily preventive maintenance pro-
cedure. (Refer to Chapter 3)
b. Place the compressor assembly on a reason-
ably level area in a well ventilated, dust-free lo-
c. Remove engine oil level gage; check oil level.
Add oil if necessary.
d. Remove dipstick from compressor and check
oil level. Two marks are near the end of the dip-
stick; correct oil level is when oil on the dipstick is
between both marks and the bottom. (Fig. 2-1) Add
oil, if below lower mark.
Oil level checks will be in error if com-
pressor assembly is not level.
e. Check gasoline tank to be certain sufficient
gasoline is in the tank by removing gasoline tank
cap and looking inside. Use regular grade gasoline.
f. Keep cart mounted compressor assembly as far
as possible from the painting operation so that
paint does not clog the engine and compressor cool-
ing fins or filters.
Do not operate the Paint Spray Outfit
in an enclosed area unless the exhaust
gases are piped to the outside. In-
halation of exhaust fumes will result
in serious illness or death.
g. If both sets of paint spray equipment are to be
used, connect both 50 foot lengths of red air hose to
air valves on pulsation chamber (Fig. 2-2). Connect
opposite ends of red air hoses to each air inlet valve
on the pressure (paint) tanks (Fig. 2-3). If neces-
sary, two 50 foot lengths of red air hose can be cou-
pled together; this will allow you to move pressure
tanks in a 100 foot circle of the compressor.
h. Connect one end of each 25 foot length of red
air hose to the air shutoff valve on each pressure
tank (Fig. 2-3). Connect the opposite end of each red
air hose to the air connection on the bottom of each
spray gun (Fig. 2-4).
i. Connect one end of each 25 foot black fluid
hose to the fluid hose connection on each pressure
tank (Fig. 2-3), Connect the other end of each black
fluid hose to the fluid connection on the bottom of
the spray gun head on each spray gun (Fig. 2-4).
Never use red air hose for fluid. Black
fluid hoses have a special lining to re-
sist chemical properties of solvents
2-3. Paint Preparation.
The Paint Spray Outfit can be used to apply any
clean paint of a consistency as used for hand-brush
application. Mix the necessary amounts of paint
and thinner. Strain the paint through cheese cloth
and pour into pressure tank insert pail. The pres-
sure tank is equipped with an air motor agitator
which will allow you to stir paint as necessary dur-
ing the painting operation.
2-4. Preparation of Respirators.
Refer to Figure 2-5 and proceed as follows:
a. Remove facepiece (10) from container, remove
two cartridges (3), two prefilters (2) and two filter
covers (1) from plastic bags.
b. Place one prefilter on each cartridge and press
filter cover over each prefilter and cartridge to hold
prefilter in place.
c. Screw both cartridges into facepiece.
