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 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 device will be aligned and leveled by
appropriate fastening elements.
4 Description of Function
4.1 Designated Use of Incomplete Device
The special construction enables the supply of a specific lubricant in a specific amount at a specific time and
location. The Dosing Valves are also suitable for use with oil.
4.2 Type Label of Incomplete Device
The Dosing Valve is marked on the side of the housing by an engraving that contains the manufacturing date
and the article number.
IMPORTANT
Always indicate the engraved data and the information from the type label for spare
part orders or technical support from WST.
4.3 Function
The pneumatic part of the dosing valve is controlled by a 5/2-way valve which is integrated in the handgrip.
This initiates the grease dosing. The dosing pressure depends on the lubricant feed pressure (medium).
Air and grease chamber are separated.

5 Initial Start-up
5.1 Mounting and Installation
IMPORTANT
We recommend adding a maintenance unit to the control air.
5.2 Adjusting the Incomplete Device
IMPORTANT
Check if the air pressure for the control air is at approx. 6 bar. This will guarantee an
optimum function of the valves.
The supply material pressure to the valve should not rise above 200 bar. Check the
pressure ratio of the supply pump. A pressure reducing valve will help you control the
supply pressure easily (a pressure reduction valve is an advantage but not mandatory
as long 200 bar will not be exceeded).
IMPORTANT
All dosing valves will be thoroughly checked before leaving our factory. It is therefore
possible that some residues of the test medium remain in the valve.
1) Make sure that the lubricant feed hose is filled with lubricant and all air is removed. Then connect
feed hose and air connectors according to drawing.
2) For first operation, set valve to maximum dosage (i.e. turn adjustment screw to outmost position.
3) If the adjustment screw cannot be turned, change position of change-over-valve. The adjustment
screw should now be unlocked.
4) Execute a first shot of lubricant. Then set the adjustment screw to the desired grease quantity.
5) Keep the distance short between the dosing valve and the greasing point. This allows for improved
metering precision and repeatability.
6) The cycle time depends on the viscosity of the lubricant, as well as on the lubricant feed pressure.

6.2 Operation Instructions / Operating Conditions
CAUTION
Do not point the jet at people. We highly recommend wearing eye protection. The
spraying process can be accompanied by noise depending on the atomizing pressure
and material pressure! If necessary, also wear ear protection.

8 Maintenance and Repair
8.1 General Information
The dosing valve is a high-quality precision device 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. 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.
CAUTION
Before starting any maintenance or repair work, ensure that all air-operated tools are
depressurized and disconnected from the air supply.
Disconnect the main power plug.
Make sure the pneumatic / hydraulic system is pressure-less.
IMPORTANT
This chapter does not tell you how to repair the device after damage. Repair work
should only be performed by a specialized technician or the maintenance team or the
manufacturer.
8.2 Routine Tasks
The maintenance intervals below refer to a single-shift operation. If the device is run in a multi-shift operation
or is operated very often, the maintenance intervals become shorter. Also, additional factors such as
cleanliness or work surroundings have to be taken into account.
