DANGER
DANGER
TAKE SPECIAL CARE WHEN WORKING ON CHAINS WHICH ARE UNDER TENSION. CORDON OFF YOUR WORKING AREA AND MAKE SURE THAT NO UNAUTHORIZED PERSONS ARE PRESENT IN THIS AREA. DURING THE TENSIONING PROCEDURE, ENSURE THAT ALL PERSONS ARE KEPT OUT OF THE DANGER AREA, I.E. ALONG THE CONVEYOR CHAIN AND IN THE IMMEDIATE VICINITY OF THE DRIVES. ALWAYS WORK FROM ALONGSIDE OF THE CONVEYOR CHAIN. WHEN USING AN ADDITIONAL PULLING DEVICE FOR COUPLING THE ENDS OF THE CONVEYOR CHAIN, DO NOT USE SO-CALLED C-LINKS (CHAIN LINK CUT OPEN). THE CLINKS COULD FRACTURE UNDER THE LOAD! YOU COULD BE SERIOUSLY INJURED OR EVEN KILLED BY THE RECOILING CHAIN! USE ONLY THE CHAIN CONNECTORS SPECIFIED FOR FASTENING AND PULLING THE CHAIN ENDS.

Please proceed as follows:
Apply pressure to the tensioning motor of the tensioning device until the required chain pretension has been reached.
IMPORTANT
BE SURE TO OBSERVE THE SEPARATE OPERATING MANUAL FOR THE CHAIN TENSIONER USED! As soon as the optional Chain Locking Device has locked into a horizontal chain link, you must depressurize the tensioning motor. Shorten or lengthen the chain. Couple the chain. The chain assembly is now pre-tensioned.
disengaging the chain locking device
NOTICE
After the chain assembly has been tensioned the Chain Locking Device must be disengaged and secured. Re-tension the chain briefly. Disengage the Chain Locking Device.
IF THE CHAIN LOCKING DEVICE IS DIFFICULT TO BE LIFTED IT IS STILL FIRMLY ENGAGED WITH THE CHAIN. NEVER TRY TO FREE THE CHAIN LOCKING DEVICE FROM THE CHAIN BY USING A HAMMER OR THE LIKE. BY RETENSIONING THE CHAIN AGAIN SLIGHTLY, THE CHAIN LOCKING DEVICE WILL BE LIFTED FROM THE CHAIN LINK. THE CHAIN LOCKING DEVICE CAN THEN BE REMOVED. Close the cover of the coal deflector.
