HOW TO CONNECT
- Job 1.
Fit the gun to fitting stay, aim at spraying direction and fix it with fitting bolts.
- Job 2.
Connect atomizing air hose to atomizing air side (AIR marked side) and operating air hose to operating air side
(CYL marked side) tightly.
- Job 3.
Connect fluid hose to fluid inlet (FLUID marked side) tightly.
- Job 4.
Pour compatible cleaning liquid into container, spray to clean fluid passages.
- Job 5.
Supply paint to container, test spray and adjust fluid output, air volume and pattern width.
Connecting example of air hose and fluid hose:
- TOF-5/5R:
Operating three-way valve, both atomizing air and piston operating air will flow and spray will start.
- TOF-6/6R:
1. Operate two-way valve to let atomizing air flow.
2. Operate three-way valve, to let piston operating air flow and spray paint.
3. In order to stop spraying, first stop three-way valve. Next stop two-way valve and then stop atomizing air.

IMPORTANT
- This
gun should be operated by adequately trained operators only.
- Ensure that the gun has not been damaged during transportation.
CAUTION
- Use clean air filtered through air dryer and air filter.
If not, dirty air can cause coating failure.
- When you use this gun for the first time after purchasing, clean fluid passages spraying thinner to
remove rust preventive oil.
If not, remaining preventive oil can cause painting failure such as fish eyes.
- Use three-way solenoid valve of more than ø 4 mm inner cross-sectional area and air hose of over
ø 4 mm inner diameter and less than 10m length.
If not, small diameter 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 can cause bodily injury
