3 Transport
3.1 Packaging
The type of packaging depends on the individual mode of shipping. If not separately contracted, the
packaging is in accordance with the rules and regulations of Walther Systemtechnik GmbH. This rule is in
accordance with the Federal Association for Packaging HPE.
3.2 Tasks before Transport
The following has to be done before transport:
Disconnect all power lines.
The actual transport of the incomplete device and its individual parts requires special care in order to prevent
damages from external forceful impact or careless on- and off-loading. Depending on the mode of
transportation, suitable transport and load securing has to be selected. The incomplete device will be aligned
and leveled by appropriate fastening elements.
4 Functional description
The SMS-17 Handpen is controlled via a mechanical manual lever. The medium is supplied from a pressure
tank or via a feed pump. The separately controlled spraying air atomizes the material into a spray jet.
Depending on the air cap used, this valve sprays in flat- or round spray
4.1 Function
CAUTION
Use of other media can result in malfunctions, property damage, or destruction of the
machine
The SMS-17 Handpen is particularly designed for a very fine application of low-viscosity media such as
colors or release agents in plastic moulds. Depending on the viscosity of the medium, the application pattern
can be adjusted individually via nozzle dimension, atomizing air pressure and material pressure. The supply
of atomizing air, control air, and material takes place via two hoses. The SMS-17 Handpen is a high-precision
tool. Always keep clean and observe minimum instructions to maintain a long life of the valve.

5 Installation and initial start-up
The valves can be used in any position. The distance to the surface where the medium will be applied
depends on the required application width.
5.1 Mounting and Installation
IMPORTANT
We recommend superposing a maintenance unit to the control air.
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 effectivity
6.2 Operating instructions
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.
It is harmless to leave fluid in the valve during longer standstills if system stays under pressure (no
connection to outside air).

8 Maintenance and repair
8.1 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
The SMS-17 Handpens are high precision tools. 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
8.2 Cleaning
IMPORTANT
Only use soft brushes for outside cleaning of the nozzle tips. Never use metal tools
with sharp edges.
Only use soft brushes for outside cleaning of the nozzle tips. Never use metal tools with sharp edges.
Wash equipment thoroughly after use to remove residues and dirt; especially, if needle, sealing bush or noz-
zle are to be exchanged.
8.3 Inserting new gaskets
IMPORTANT
When inserting O-rings and gaskets, do not use any sharp or pointed metallic imple-
ments. Especially the gasket is a very precise and sensitive component that is not able
to stand impacts.
8.4 Needle-valve unit
When assembling the needle-valve unit make sure the two needle nuts (16) are mounted and countered
according to the below drawing.
