10.3 Regreasing the sealing unit
The sealing unit requires almost no maintenance. However,
it is necessary to regrease the seal’s depot every quarter, or
for heavy use, every month. If this maintenance measure is
not carried out or not carried out in time, the sealing rings
may run dry, causing the seal to fail prematurely.
1. Use a grease gun with roller bearing grease.
2. Press the grease into the grease nipple (1) provided until
excess grease comes out of the pressure relief valve (2).
