Dismantling the coupling
DANGER
Risk of explosion when operating the coupling in potentially
explosive atmospheres.
Risk of explosion with fatal injuries.
Exclusively use couplings bearing the corresponding ATEX
marking in potentially explosive atmospheres.
In this respect, read and follow the additional notes in the
supplementary manual for ATEX operation.
DANGER
Danger to life due to falling or tipping loads.
Pay attention to the centre of gravity of the load.
Use a crane of adequate load-carrying capacity to lift the
load.
Use lifting gear of adequate load-carrying capacity to lift the
load.
Make sure that no persons are under suspended loads.
To handle the coupling, follow the instructions on page 23.
Obtain the work clearance permit from the responsible person prior to all work on
and with the coupling.
Switch the drive unit off.
Secure the drive unit to prevent reactivation.
Post up a caution sign indicating that work is in progress.
Wear the personal protective equipment specified by the owner.
Pull the drive unit and the driven machine so far apart that there is sufficient space
for disassembly.
Secure the coupling flange in a suitable manner to prevent it from falling down.
Remove the bolts and washers from the coupling flange.
Put the coupling flange down on the designated surface.
Secure the coupling element and, if fitted, the spacer ring in a suitable manner to
prevent them from falling down.
Remove the bolts between the coupling element and the hub.
Put the coupling element and, if fitted, the spacer ring down on the designated
surface.
Secure the coupling hub in a suitable manner to prevent it from falling down.
Remove any existing axial lock, for example the set screw.
Pull the coupling hub off the shaft of the driven machine in a suitable manner.
Lay the coupling hub down on a designated surface.
