OPERATION AND MAINTENANCE
The Model 115 Gun in normally used for touch-up, stenciling, and
small work spraying.
CONTROLLING THE FAN SPRAY
The fan spray for an external mix nozzle set-up is easily controlled
by means of the side port control assembly (17). Turning the valve
stem (19) 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 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 regulating the pressure on the tank. The amount of
fluid can also be controlled by means of the fluid control screw (21).
Turning this screw to the right, or clockwise, 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 damage 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 FLUID PACKING
Remove the fluid control screw (21), spring (23) and fluid needle (3). Then
remove the fluid packing nut (25) and take out the old packing with a
small stiff wire. Replace with new packing (8). Oil lightly and reassemble
in reverse order. Do not over tighten fluid packing nut. Doing so can
prevent needle movement.
CORRECTING AIR LEAK THROUGH GUN
OR AROUND AIR VALVE STEM ASSEMBLY
Air leaking through the gun is caused by the air valve stem assembly (20)
not seating properly. Air leaking around the air valve stem assembly (20)
may be caused by worn packing (8) or damaged air valve stem assembly
(20). Remove air connection (24), spring (15), air valve stem assembly
(20), valve nut (14) and packing (8). Thoroughly clean parts, put one
drop of oil on packing (8) and reassemble in reverse order.
CLEANING THE GUN
WHEN USED WITH PRESSURE TANK
Shut off the air supply to the pressure tank and release the pressure in
the tank. Hold a piece of cloth over the gun nozzle and pull the trigger,
the air will back up through the fluid nozzle and force the fluid out of the
hose and into the tank. Remove paint from tank, clean tank and put
enough compatible solvent into the tank to clean the hose and gun
thoroughly. Spray this through the gun triggering the gun intermittently
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.
CLEANING THE GUN WHEN USED WITH A CUP
A compatible solvent should be siphoned through gun by inserting tube
from siphon cup in an open container of solvent. Trigger gun
intermittently to thoroughly flush passageways and internal parts.
WARNING
REGARDING AIR PRESSURE SAFETY
Shut off air pressure before connecting or disconnecting air hose or
removing any components from the gun. Servicing the gun while pressur-
ized could result in damage to components or bodily injury.
