Install and operate the spray gun according to above figure.
Verify the cleanness of fluid and air hoses before connection.
Check that all connections are tight.
Keep the spray gun clean and lubricate moving parts at
regular intervals.
Lubricants for surface-treatment equipment must not
contain silicon.
In the event of leakage around the paint needle, tighten the
packing screw (see F in the above figure) . After tightening,
check that the spring is still able to push forward the fluid
needle.
For short standstill periods, for instance over a night, it will
suffice to clean the paint nozzles and the air cap on the outside;
for longer standstill periods the gun must be flushed through
immediately with appropriate solvent.
If a two-component paint is used, however, the flushing
operation must be done no later than the pot-life time (refer
to data sheet from the paint manufacturer).
When cleaning the air cap and the paint nozzle, use a soft
brush or rag dipped in solvent. Do not place the whole gun in
solvent to avoid damaging.
Never use iron or steel wire to clean air holes and ducts in the
nozzles.
Switch the on/off pneumatic control valve in advance to
compensate, if needed, the response time of the gun.
Recommended size for control valve: 3-way, G 1/4".

Clockwise turning result in a smaller
paint flow and counter-clockwise turning
increases the flow. The fluid flow is
regulated in the first instance by the choice
of paint nozzle and paint pressure.
