7 Service, Repair and Malfunction
7.1 General Information
CAUTION
Before starting any maintenance or repair work, ensure that all air-operated tools are
depressurized and disconnected from the air supply.
Before opening the spray valve, it must be disconnected from the air and fluid supply.
Otherwise, ejected components can cause injuries. Wear safety goggles.
The spray valve will be regularly checked for wear and tear. Wear and tear depend upon the
processed material, switching frequency and the conditions of use.
The spray valves of the
SMS-11
series are high-quality precision devices which will not fail if treated correctly
and will operate almost maintenance-free. Always keep clean and observe minimum instructions to maintain
a long life of the valve. We recommend lubricating moveable parts regularly and greasing threads, especially
the nozzle threads, when replacing or cleaning the nozzle. Always use clean and filtered material only. The
control air must also be clean and should be slightly oiled, if necessary. Maintenance also depends on the
individual operating conditions and the type of media used.
Particularly when employing the spray valve as color-marking device, the spray cap should be taken off
before a longer standstill. The spray nozzle will be cleaned with a special thinner and a soft cloth. Make sure
that there are no cloth fibers on the nozzle tip.
7.2 Cleaning
Wash equipment thoroughly after use to remove residues and dirt, especially if nozzle needle, needle
sealing or nozzle have to be exchanged (see also
7.4
and
7.5
).
IMPORTANT
Only use soft brushes for outside cleaning of the nozzle tips. Never use metal tools with
sharp edges!
During all repair and replacement tasks, take care that the working station as well as the
device for repair will be kept in uttermost cleanliness.
We recommend removing the devices from the machines instead of leaving them installed
during major repair works. (Disconnect the supply lines from pressure!).
7.3 Spare Parts
IMPORTANT
Only use original spare parts from the manufacturer!
Wrong or defective spare parts from other manufacturers can damage the device. If other
than original spare parts of the manufacturer will be used, all obligations from the manufac-
turer or his sales partners, such as guarantees, service contracts etc. will be
forfeited
with-
out further notice.
