Service and maintenance
8.2 Description of maintenance and repair work
The lockable manual release of the brake must be kept in the released state for maintenance
work.
Figure 8-1
Locking the manual brake release lever
1. Screw on the manual brake release lever.
2. Bring the manual brake release lever into the position in which the brake is released.
3. Tighten the locking screw far enough so that the manual brake release lever cannot
return to the unreleased position.
You can now start maintenance work on the plant with a released brake.
Releasing the lock
1. Unscrew the locking screw far enough so that the brake can completely return to the
unreleased position. The gap between the locking screw and the manual brake release
lever must be 2 to 5 mm.
2. Unscrew the manual brake release lever.
You have ensured that the manual brake release is no longer locked.
8.2.2
Lubrication
The bearings of the standard version surface-cooled motors up to size 200 are permanently
lubricated. If this is not the case, this is indicated by a warning notice on the motor.
The specified grease service life values are valid for an ambient temperature of max. +40 °C.
For every 10 °C increase in temperature, the grease service life is reduced by a factor of 0.7
of the value in the table (max. +20 °C = factor 0.5).
At an ambient temperature of +25 °C, the grease service life can be expected to be doubled.
Irrespective of the number of operating hours, renew the roller bearing grease or the bearing
(2Z bearing) after 3 or 4 years at the latest.
