General
The product is a sensitive component and must therefore be handled with care. You
must not subject the product to hard impacts and keep it away from magnetic parts!
Until it has been installed in the pump housing, the original packaging is the safest
place to store it.

Installing the VT-SWA-LIN-...-G15 swivel angle sensor
▶ Tighten the sensor to 25 +
5
Nm (WAF 27).
▶ Tighten the sensor cable on the pilot control valve to 0.6±6% Nm.
▶ Calibrate the swivel angle offset and factor according to chapter8.1.8 "Calibrating
the HS5E control system" on page75.
By quoting the Mat. No. of the pump, you can get seal kits that are either matched to
specific individual components or are a complete package.
The pilot valve is a component that is sensitive to contamination. When replacing it,
make sure that no contaminants enter fluid-carrying parts of the valve and the pump.
Before replacing the new control valve, Bosch Rexroth recommends saving the
parameters of the valve to be replaced and to transfer the data to the replacement
valve.
