Installing Drive Belt

Information 

• Using an open-ended wrench can damage the belt tensioner. 
• Using a tool with a width across flats of 32 mm can damage the belt tensioner. 

1. Fit used drive belt in the rolling direction according to removal marking. Fit drive belt straight on all pulleys without tilting it (leave loop in front of tensioning roller -6-) -1 bis 8-  . Finally, turn the belt tensioner clockwise at the hexagon -9-  using a ring wrench (width across flats 30) or change-over ratchet with socket and place the drive belt around the tensioning roller -6-  . Then relieve the belt tensioner slowly.
