Maintenance and inspection
WARNING

First release air and pressure fully according to item No.2 of “Improper use of equipment” of WARNING on page 1 to 2.
 Tip of fluid needle set has a sharp point. Do not touch the tip of needle valve at the maintenance.
 Be careful not to damage the tip of fluid nozzle.
 Only an experienced person who is fully conversant with the equipment can do maintence and inspection.
.
CAUTION
 Never use commercial or other parts instead of original spare parts.
 Never immerse the whole gun into any solvent or cleaning solution such as thinner for over 1 minute.
If not, it may be detrimental to the lubricants, and the seals inside may be out of shape and lead to leakge, even there’s no any
rubber parts used inside the gun, such as o-ring.
 When replacing the fluid nozzle or fluid needle, replace both at the same time.
Using worn parts can cause fluid leakage. Also, replace the needle packing at this time.
Torque the fluid nozzle to 18~20Nm (160~180lb.in).
 To prevent damage to fluid nozzle or fluid needle, be sure to either pull the tirgger and hold while tightening or loosening
the fluid nozzle, or remove fluid adjusting knob to relieve spring pressure against needle collar.
 The gravity cup is made from special anti-static materials, but it is still improtant to avoid generating static charges.
The cup must not be claned or rubbed with a dry cloth or paper. It is possible to generate a static charge by rubbing witch, if
discharged to an earthed object could create an incendive spark and cause solvent vapours to ignite.
Only use a dampened cloth or antistatic wipes if manual cleaning is required within a hazardous area.
 For routine clean/maintenance, do not dismount any other part than air cap, nozzle and needle from the gun (The spray
head may needs to be cleaned it it is dirty).
If not, the seals & packings inside may face a risk of being out of shape and lead to leakage.
Step-by-step procedure
Important
1. Pour remaining paint out after use. Clean fluid passages and air
cap set. Spray a small amount of thinner to clean fluid passages.
1. Incomplete cleaning can fail pattern shape and uniform
particles. Especially clean fully and promptly two-component
paint after use
2. Clean each section with brush soaked with thinner and wipe out
with waste cloth.
2. Do not immerse the whole in thinner for over 1 minute. If done,
it may damage parts inside, and lubricating may be needed.
3. Before disassembly, fully clean fluid passages.
(1) Disassemble fluid nozzle.
Use spanner to remove fluid nozzle.
(2) Disassemble fluid needle set.
You do not need to remove fluid/needle adj. guide set from
gun body. Remove fluid adj. knob and fluid needle spring, and
then pull out fluid needle spring, and then pull out fluid needle
from back of housing.
3. During disassembly, do not scratch housing section.
(1) Remove fluid nozzle after removing fluid needle or while
keeping fluid needle pulled, in order to protect housing
section.
(2) Be careful when handing tip of fluid needle since it is sharp.
4. In order to assemble air valve, first assemble air valve & air valve
spring & fluid adj. guide together.
Next, insert fluid needle set into fluid adj. guide set, then fit it to
gun body set and screw fluid adj. guide set.
4. Service air valve only when it is not functioning correctly (may
need cleaning) or significantly air leaks.
If you try to fit air valve spring and air valve to gun body without
fluid needle set, air valve will not be fitted correctly and lop
packing inside fluid adj. guide will be damaged.
5. When you want to adjust fluid needle packing set, first tighten it
by hand while fluid needle set remains inserted.
Then tighten it further carefully by spanner,
5. Service needle packing only when it is not functioning correctly
or significantly air leaks.
Too much tightening of fluid needle packing nut can cause bad
movement of fluid needle set and fluid leakage from the tip of
fluid needle.
When you tighten it too much, first fully loosen it and then
tighten it again carefully.
6. Turn pattern adj. knob or air adj. knob counterclockwise to fully
open, and then tighten pattern adj. set or air adj. set.
6. If pattern adj. knob or air adj. knob is not fully opened, tip of it
can contact and damage fluid nozzle and cause seizure of
thread.
Where to inspect
Parts replacement
1. Each hole passage of air cap and fluid nozzle.
Replace if it is crushed or deformed.
2. Packing and seals
Replace if it is deformed or worn out.
3. Serious leakage between fluid nozzle and needle.
Replace them both if leakage does not stop after fully cleaning fluid
nozzle and fluid needle.
