HOW TO CONNECT
1. Fit the gun to fitting stay, aim at spraying direction and fix it.
2. Connect atomizing air hose to atomizing air inlet (CAP marked side) and operating air hose to operating air inlet (CYL marked side)
tightly.
3. Connect fluid hose to fluid inlet (FLU marked side) tightly.
4. Flush the gun fluid passages with a compatible solvent.
5. Supply paint, test spray and adjust fluid output, air volume and pattern width.

CAUTION
- Use clean air filtered through air dryer and air filter.
If not, dirty air can cause painting failure.
-
When you use this gun for the first time after purchasing, clean fluid passages spraying thin-
ner to remove rust preventive oil.
If not, remaining preventive oil can cause painting failure such as fish eyes.
- Use two-way or three-way solenoid valve of more than ø 4 inner dia. cross-sectional area and air hose of over
ø 6 inner dia. and less than 10m length.
If not, small dia. of solenoid valve and longer air hose between three-way
solenoid valve and gun can cause delay in operation.
- Firmly fix hose to spray gun.
If not, disconnection of hose and drop of container can cause bodily injury
