◼

Do not place any unnecessary combustibles such as coating materials and solvents in the spray area.
No-smoking at painting area. It can cause a hazardous condition and result in fire of explosion.
Operators and objects in the spray area must be grounded securely. Grounding condition must be
checked at least before starting operation every day.
Keep a fire extinguisher at painting area.
Sufficiently ventilate the spray area so that combustible solvent vapor does not stay.
Spray booth ventilation must be kept at the rates required by country and local codes.

Toxic vapors - When sprayed, certain materials may be poisonous, create irritation or be otherwise
harmful to health. The use of respiratory protective equipment is recommended at all times.
Wear safety glasses. Failure to wear safety classes with side shields could result in serious eye injury
or blindness.
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,inhaled, injected or swallowed. Learn and know the specific hazards or the fluids you are using.
Appropriate clothes and gloves must be worn for spraying or cleaning the equipment.

Equipment Misuse
Operator training. All personnel must be trained before operating finishing equipment.
Never aim a spray gun at any parts of the body.
Don't clean suction or gravity feed spray gun with HD-QCH.
Connect the air hose firmly using a spanner to prevent leaking. A loose air hose may cause it to comeoff, resulting in damage to personnel, workpiece and peripheral equipment.
Replacing spring-loaded and compressed air contained parts may result in safety hazards to personnel.
Always use under this maximum pressure (0.69MPa).

Installation
1.

This equipment must to be fixed at stable place otherwise it could cause serious inquiry.

Attaching example 1 :Make two or more holes of between φ6.2 to 6.5 suchas in the frame of the mount pad, then thread bolts

Attaching example 2 :into the screw holes on the device to tighten it.

Make two holes of between φ 6.2 to 6.5 on the top
plate of the mount, attach the multi bracket to thedevice, and then tighten the top plate and the multibracket with bolts and nuts.

Attaching example 3 :Sandwich in the round pipe of the mount between the device and themulti bracket, and tighten them with four bolts in a well- balanced way.

Clean, moisture and oil free air supply is needed. Install mist separator or transformer at closer place asmuch as you can. Contaminated air may lead to problems with coating or coating equipment including
this device.
Use cleaning solvent or water (hereinafter referred to as "cleaning solutions") to be supplied to thisdevice. Running dirty cleaning solutions or paints may cause damage to this device or may result inpoor cleaning.
Connect the cleaning solutions hose / air hose firmly. A loose hose may cause it to come off, resulting indamage to personnel, workpiece and peripheral equipment.
When installing the cleaning solutions hose / air hose, use sealing tape etc. and tighten with a tool.
A loose hose may lead to problems with cleaning solution leaks or air leaks.
A check valve (R1 / 4, No. 5 on the parts list) is attached to the air supply side of this device. The
cleaning solutions may flow back to the air circuit, causing peripheral equipment failures or malfunctions
if the check valve is removed or still being used even after it has failed.
Operations can be made easily if you install ball valves or regulators on the air supply side and cleaning
solutions supply side.

Do not run paints / dirty cleaning solutions for this device.
If the difference of supply pressure between the cleaning solutions and the air is large, mixing will bedifficult, so adjust the pressure to the same level in advance.
Fully turn the fluid adjustment valve and air adjustment valve knob to the right to close it. *It does notstop completely.
Open the "outlet valve" and supply the cleaning solutions first and air in order.
How to adjust the cleaning solutions flow rate and air flow rate.
a For both knobs, turn clockwise to decrease the flow rate or turn counterclockwise to increase theflow rate.
b First, turn the fluid adjustment valve knob to adjust the flow rate of the cleaning solutions.
c Next, turn the air adjustment valve knob to mix the air with the cleaning solutions.
d Adjust the flow rates of cleaning solutions and the air till the efficient cleaning can be madepossible.
Shut off the supply of air first and then the cleaning solutions in order after the cleaning process isfinished, close the outlet valve.
The settings for the fluid adjustment valve and air adjustment valve can be used as they are from thenext time if the supply is controlled by a ball valve or a regulator. * Please configure again if the supply
pressure has changed.

Operation
1.
2.

Perform daily cleaning to ensure the best usability and performance of this device.
Never completely immerse in any cleaning solutions as this is detrimental to the lubricants and life of
the spray gun. Immersing this device in liquid may deteriorate the seal, resulting in cleaning solutions
leaks or air leaks.

Parts Replacement
Before replacing parts, drain the cleaning solutions and dry first, then remove all hoses.
Please perform this task in a flat and clean place. Wear safety glasses and use appropriate tools as specified.
