6 Operation
6.1 General Information
This device may only be operated if the safety-related equipment is permanently effective and not suspend-
ed during operation or altered in its intended effectiveness.
6.2 Operation Instructions / Operating Conditions
CAUTION
Never point the jet at people. The wearing of eye protection is strongly recommended.
The spraying process can create noise depending on the air and fluid pressures used.
Ear protection should be worn, if required.
WARNING
Danger caused by flammable, harmful fluid. Always follow the safety instructions on the
container or the safety data sheet for the fluid
The valves can be controlled for intermittent or continuous use. According to the individual applica-
tion, the control air must be adjusted to the operating cycles and to the higher or lower material pres-
sures. 40 tacts per second can be reached under appropriate operating conditions (material pres-
sure, control air pressure, needle stroke, short conductions).
The VMS-08 usually works with a control air pressure of 5 – 7 bar.
During longer standstills the material can remain in the valve as long as it is under pressure and
does not have any contact with outside air.
Material and control air will only be used in a clean, filtered condition. Control air should be slightly
oiled when supplied to the spraying device.
The valves of the VMS-08 series usually operate with a control air pressure of 5 - 7 bar. In case high
material pressures are necessary, the safety regulations of the trade association must always be ob-
served.
6.3 Adjusting and Setting
IMPORTANT
The amount of material can be individually regulated via the regulating screw.
Right turn: decreasing material quantity
Left turn: increasing material quantity
Nozzle and needle can be damaged by wrong handling.
Only decrease the material flow (by a right turn of the regulating knob) if material is
discharged.
Do not turn the regulating knob further to the right after the nozzle is closed!
During longer standstills the material can remain in the valve as long as it is under pressure and does not
have any contact with outside air.
