Caution!
The contact guard must be inspected for damage (e.g. due to incorrect transportation) as
contact with the fan may overload the gear unit.
4.6 Checking the Taconite seals
If Taconite seals are installed, check whether there is a gap between the bearing cover plates
(Pos. 1 and Pos. 2), and that this is filled with grease. Relubrication is carried out via the conical
grease nipple M10x1 - DIN 71412 (Pos.3).

4.7 Pressure safeguard
The pressure safeguard is an electric switch, which monitors the lubrication pressure of gear
units with circulation lubrication or targeted lubrication. If the pre-set pressure is undershot, the
applied electric signal is interrupted by the pressure safeguard. Evaluate the signal accordingly.
Caution!
Connect the pressure safeguard so as to be fully functional before starting operation for the
first time. The pressure safeguard can only be used in combination with a monitoring system.
Note!
Evaluate the pressure safeguard after initially operating the pump, as pressure must be built
up.
