7.4 Servicing the gripper
NOTE
SCHUNK recommends dismantling, dry cleaning without degreas-
ing agents and re-lubricating for every maintenance interval, to
ensure that every lubrication point is optimally supplied with
grease.
If the gripper is not dismantled during maintenance, not every
lubrication point can be optimally supplied with lubricant.
