en
▪ Only original parts from the manufacturer may be used
for maintenance and repairs. Use of parts other than
the original parts releases the manufacturer from any
liability.
▪ Collect any leakage of fluid and operating fluid immedi-
ately and dispose of it according to the locally applic-
able guidelines.
▪ Store tools at the designated locations.
▪ After completing work, reattach all safety and monitor-
ing 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 ejected at high speed! To
avoid injuries, observe the following instructions:
▪ Adhere to the prescribed sequence of work steps.
▪ 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 fluid can also spray out
when the pressure is escaping. This can result in
scalding! To avoid injuries, allow the motor to cool
down to the ambient temperature before carrying
out any work!
▪ When the pressure has completely dissipated, fully un-
screw the screw plug.
