Sparks and open flames are strictly prohibited. Paints can be highly
flammable and can cause fire. Do not expose to open flames, electrical
goods, cigarettes etc.
Securely ground spray gun using conductive air hose. (<1MΩ). Always
ensure that the spray gun is earthed correctly.
PROTECTION OF HUMAN BODY
Use in a well-ventilated site, using a spray booth. Poor ventilation can
cause organic solvent poisoning and fire.
Always wear protective gear (safety glasses, mask, gloves) to avoid
inflammation of eyes and skin. In case of any physical discomfort, imme-
diately seek medical advice.
Wear earplugs if necessary. Noise level can exceed 85 dB(A), depending on
operating conditions and painting site.
Pulling the trigger many times during operation, may cause carpal
tunnel syndrome. Always rest, in case of tiredness.
IMPROPER USE
Never point gun towards people or animals.
Never exceed maximum working pressure or maximum operating
Temperature
Always release air and fluid pressure before cleaning, disassembling
or servicing. Otherwise, remaining pressure can cause bodily injury due to
improper operation or scattering of cleaning liquid.
Tip of fluid needle set has a sharp point.
Do not touch the tip during maintenance to avoid accidents.
Never use this gun to spray foods or chemicals. Otherwise, foreign
substance, could cause corrosion of fluid passages which could adversely
affect health.
Never alter this spray gun, to avoid insufficient performance and damage.
If something goes wrong, immediately stop operation and find the
cause. Do not use again, until you have solved the problem.
Do not enter working areas, where robots, reciprocators, etc. are used,
until they have been turned off. Otherwise, they could cause injury.

needle packing set, spray cleaner to clean fluid passages and remove
190
rust preventive oil.
100
Firmly fix the paint supply hose or a suitable container to spray gun, to
135
avoid that disconnection of it, can cause bodily injury.

230
Suggested atomizing air pressure varies according to each model, and it is
165
listed in the Specifications Table. (see left)
185
Recommended paint viscosity differs according to paint property and pain-
ting conditions.
Set the spray distance from the gun to the work piece, as near as possible
within the range of:
200 ~ 250 mm (8 ~ 10 in) (W-77) and 150 ~ 200 mm (5.9 ~ 7.9 in) (W-71)
The gun should be held so that it is perpendicular to the surface of the work-
piece at all times. Then, the gun should move in a straight and horizontal
line. Arcing the gun causes uneven painting.
