Plug (6) or Fluid Insert(9)
Halogenated Hydrocarbon solvents can chemically
react with aluminum. A risk of explosion or severe
corrosion will occur. The following assembly step
must be carefully performed.
If replacing AGX-415 inlet fitting, or if it should loosen, follow
assembly procedures below.
1. If installing a used fitting, clean paint and thread sealant
from fitting threads and gun body using a brass or bronze
wire brush/bottle brush.
2. Screw jam nut all the way onto fitting. Then apply Loctite
medium strength #242 (blue) to first few threads of the fit-
ting.
3.
Install AGX-415 fitting into spray gun and tighten to a maxi-
mum of 12 ft. lbs. torque. (Do not overtighten, damage may
occur.)
4. Tighten jam nut to 16 ft. lbs. torque using a thin 9/16" open
end wrench.
5. Use two adjustable wrenches when removing a hose con-
nection from AGX-415 to prevent inlet fitting from loosening.

AGX-402-FX needle.)
JGHV-101-83MP
(For Max. Performer, also order
AV-2120-E fluid tip and AGX-402-E
needle OR AV-2120-D fluid tip and
AGX-402-D needle.)
LUBRICATION
The piston o-rings (17 and 18) must be lubricated when piston
(19) is removed. Lightly lubricate with clean petroleum jelly.
Petroleum jelly is effective as a lubricant up to approximately
110°F. Above 110°F, petroleum jelly will become "liquid" and
will not lubricate the o-rings adequately. If ambient temperature
adjacent to spray gun exceeds 110°F, use Parker O-Lube. This
allows the spray gun to be used in temperatures up to 150°F
continous without lubrication degradation.
Lubricate outside of larger piston spring (30) and needle spring
(27) with a light coating of non-silicone grease. Apply a thin film
of petroleum jelly to fluid needle (28) as shown on page 6, note 1.
Note
Due to close part tolerances, after repairing the gun,
actuate gun on and off 7 or 8 times to "break-in" the
packings. Do this with material supply off.
Clean threads
16 ft. lbs. torque
12 ft. lbs. torque
Do not overtighten.
