Changing operating fluid
In the event of a motor defect, pressure of
several bar can build up
in the sealing
chamber! This pressure is released when the screw plugs are
opened
. If screw plugs are
opened without due caution, they can be ejected at high speed! To avoid injuries, ob-
serve the following instructions:
ƒ
Adhere to the prescribed sequence of work steps.
ƒ
Unscrew the screw plugs slowly, but never unscrew them completely. As soon as
pressure is released (audible whistling or hissing of air), stop turning the screw plug
any further.
WARNING! Hot operating fluids can also spray out when pressure is released. This
can result in scalding! To avoid injuries, allow the motor to cool down to the am-
bient temperature before carrying out any work!
ƒ
When the pressure has been completely released, fully unscrew the screw plug.
