WA-200 | WA-101 | LPA-200 Automatic Spray Gun
5. MAINTENANCE & INSPECTION
Before carrying out maintenance and inspection ALWAYS observe SAFETY WARNING
indications.
Never use spare parts that are not ANEST IWATA originals.
Never damage fluid nozzle tip, fluid needle or air cap holes.
Never immerse the spray gun completely in liquids such as thinner.
Never soak air cap in cleaning liquid for extended period even if cleaning.
Never use metal objects to clean the gun.
5.1 CLAENING PROCEDURE
The fluid passages of the gun, must be cleaned thoroughly after each use,
especially after use with bi-component paints.
Incomplete cleaning can cause defective pattern shape.
Clean fluid passages and air cap set (1). Spray a small amount of cleaner to clean fluid
passages. Incomplete cleaning can fail pattern shape and uniform particles.
Clean each section with brush soaked with cleaner and wipe out with waste cloth.
Do not immerse the whole gun in the cleaner. If done, it can damage parts. When cleaning, never
scratch any holes of air cap set, fluid nozzle, or fluid needle set.
5.2 DISASSEMBLING AND ASSEMBLING
BEFORE DISASSEMBLY, CLEAN FLUID PASSAGES
Remove the air cap set (1), with the fluid adjustment set fully opened, unscrew the hexagon
nut of the adjustment and remove the fluid adjustment set (9), the piston spring (8) and
needle spring (7), then extract the needle set (2-2) in a straight line from the gun body, in
1.
order to protect the needle packing set (11). During this operation, pay attention that the fluid
adjustment set (9) does not fly out suddenly since it is strongly pushed by the needle spring
(7) and piston spring (8).
After removing the needle set (2-2), unscrew the fluid nozzle (2-1) and remove it from its seat,
2.
remove the protection cover (12) of the needle packing, unscrew the hexagon nut of needle
packing (11) and take it out from gun body.
To remove the piston set (6-2), screw the rear section of fluid needle set (2-2) into piston and
pull it out from the gun body. Only in the case of WA-200 ZP, use the extraction bolt (17) to
pull out the piston from gun body. During this operation be careful to not damage the piston
packing (6-1) and the O'ring.
3.
IMPORTANT: During the reassembling of the piston (6-2), apply the grease to the piston
packing (6-1) and to the O'ring (5-3), to avoid any impediments to the movement of
the piston.
IMPORTANT: TO REASSEMBLE REVERSE THE PROCEDURE, FOLLOWING THE POINTS IN
DECREASING ORDER (3-2 and 1).

5.3 IMPORTANT RECOMMENDATIONS

Fluid needle packing set (11), must always be adjusted while fluid needle set (2-2)
is inserted and in the following way: tighten it by hand (about a 60 degrees turn)
and then with spanner. When you remove needle packing set (11), do not leave the
plastic piece of needle packing set in the gun body.
IMPORTANT: If you tighten fluid needle packing set (11) too much, fluid needle set (2-2) will not
move smoothly, resulting in paint leakage from tip of fluid nozzle (2-1).
Try to adjust it carefully while pulling trigger and confirming movement of fluid needle set (2-2)
If you tighten it too much, repeat operation.
When replacing fluid nozzle set (2-1) and fluid needle set (2-2), check the correct coupling
of both, in order to avoid any paint leakage from the fluid nozzle during spray gun operation.
When closing the fluid adjustment set (9) and the fluid nozzle (2-1), always make sure that
the fluid adjustment knob is completely loosened.
