AIRLESSCO 007X & XL SPRAY GUNS
ADJUSTING SPRAY GUN
Hold gun with trigger locked (24) and push trigger
against the lock (16). Then adjust nut (14) so that
the retainer (13) will move freely back and forth
approximately 1/32" to allow valve spring unit (8)
to seat the valve ball (7).
IMPORTANT: Readjust nut (14) periodically for
wear of valve seat (6) and valve ball (7); other-
wise, leakage will occur.
TO REPLACE THE VALVE BALL HOLDER (7)
KIT #2-007
3 Tip Washers (3)
1 Valve Seat (6)
1 Valve Ball Holder (7)
2 Seals-Teflon (8a)
Dismantling:
1. Unscrew tip holder (1) with a 7/8" open end
wrench. Remove spray tip and washer (3).
2. Unscrew valve seat (6) with 1/2" socket wrench.
*Caution*
When removing and replacing valve
seat (6), hold the trigger (24) in the open
position so that the valve ball (7) is lifted
off the valve seat. Failure to lift the ball
off the seat will result in a scratched
leaky valve.
3. Unscrew valve ball (7) together with the brass
part of the assembly (8). Do not pull on the parts
or the packing may get damaged.
4. Unscrew the valve ball (7) from the brass part
of the assembly (8).
Reassembling
is done in reverse sequence.
Screw the new valve ball with holder (7) into the
brass part (8).
*Caution*
Tighten valve ball and brass part on
threaded end of the shaft by hand
until you feel a positive stop. Do not
tighten with a wrench since this could
result in breaking the shaft.
Note it is recommended that you change the valve
seat (6) and valve ball (7) at the same time.
Push firmly into gun head by hand. Install retainer
pins (12), retainer (13) and nut (14) loosely onto
valve spring unit (8). Place a 3/16" nut driver on
front of valve spring unit and turn clockwise,
tightening the valve spring unit until you feel a
positive stop. At that point, continue tightening
the valve spring another 1/8 turn expanding the
Teflon seals against body of gun.
Do not tighten beyond 1/8 turn as this can
result in breaking the valve spring unit shaft.
Continue reassembly and adjustment as de-
scribed above.
*Caution*
CLEANING 007 SPRAY GUN
Immediately after the work is finished, flush the gun
out with a solvent. Brush pins (12) with solvent and oil
them lightly so they will not collect dried paint.
CLEANING SPRAY TIP
Should the spray tip become clogged, relieve pres-
sure from hoses by following the "Pressure Relief
Procedure" in Machine Manual, secure the gun with
safety lock (16), take off tip holder (1), take out the
tip, soak in appropriate solvent & clean with a brush.
(Do not use a needle or sharp pointed instrument to
clean the tip. The tungsten carbide is
brittle and can chip.)
CLEANING FILTER
To clean the filter, use a brush dipped in as
appropriate solvent. Change or clean filters
at least once a day. some types of latex may
require a filter change after four hours of
operation.
tainer pins (12) and push shaft of the valve spring
unit (8) out of the gun head (11).
3. Clean gun head (11) bore with solvent and small
brush. Do not use any sharp objects to scrape away
dried paint, as they would cause leakage around
the seal.
Reassembling
is done in reverse sequence.
IMPORTANT: When reassembling, install valve
spring unit (8) with spring loose.
1. Repeat dismantling procedure as outlined above
under Steps 1 through 3.
2. Unscrew nut (14), remove retainer (13) with re-
