A chain drive will provide long, trouble-free operation when properly installed and serviced.
The following information is important for machine maintenance and keeping repair costs to a minimum.
Check chains frequently during the first few hours of operation. Adjust tensioners to maintain correct tension. The amount of slack in a chain should be approximately 2% of the distance between centers of drive and driven sprockets.
Example: If distance between center of drive sprocket and driven sprocket is 254 mm (10 in.), slack in chain should be 6 mm (1/4 in.).
The slack is measured at the center of chain span opposite the tensioner sprocket. Make sure all slack is

removed from tensioner sprocket side of the chain before measuring slack on opposite side.
Chains which are too slack will cause rapid and excessive wear of chain rollers, sprocket teeth, and possibly machine components which the chain is driving.
Chains which are tensioned too tight may result in damage to bearings and shafts. Too much chain tension can also cause rapid wear of the chain itself.
NOTE:
For correct chain service, also refer to "Storage after the Season".
