8.1 Maintenance intervals8.1 Maintenance intervals
DANGER
Danger due to bursting of the coupling
The coupling can burst if the maintenance intervals are not adhered to. There is a risk of
fatal injury from flying fragments. Bursting of the coupling can lead to an explosion in po-
tentially explosive atmospheres.
• Please observe all the stipulations concerning maintenance of the coupling in this sec-
tion.
DANGER
Danger due to sparking or bursting of the coupling
If the lubricant quantity does not correspond to the quantity stipulated, then the coupling
becomes an ignition source. Lubricant shortage can lead to sparking. Sparks can lead to
an explosion in potentially explosive atmospheres.
• Carefully observe the specified lubricant quantity.
WARNING
Physical injury
Injury from rotating parts.
• Only carry out work on the coupling when it is at a standstill.
• Secure the drive aggregate against unintentional startup.
• Attach an information notice to the start switch stating clearly that work is being carried
out on the coupling.
• Before starting any work, make sure that the unit is free from loads.
Check the coupling every 3 months for any for leakage, heating and change in noise level.
