and dispose of it according to the locally applicable guidelines.
ƒ
Store tools at the designated locations.
ƒ
After completing work, reattach all safety and monitoring
devices and check that they function properly.
Changing operating fluid
In case of a defect, a pressure
of several bar can build up
in the
motor! This pressure escapes when the screw plugs are
opened
.
If screw plugs are opened without due caution, they can be ejec-
ted at high speed! To avoid injuries, observe the following in-
structions:
ƒ
Adhere to the prescribed sequence of work steps.
ƒ
Unscrew the screw plugs slowly, but never unscrew them
completely. As soon as the pressure escapes (audible whistling
or hissing of air), stop turning the screw plug any further.
WARNING! Hot operating fluids can also spray out when the
pressure is escaping. This can result in scalding! To avoid in-
juries, allow the motor to cool down to the ambient tem-
perature before carrying out any work!
ƒ
When the pressure has completely dissipated, fully unscrew
the screw plug.
