Selecting the right option
Choose the roller size from the dimensions in the table, checking that the roller width suits the chain you are tensioning. The catalogue lists the heavy tension box as the standard setting and a light tension box, ET-SNUL, as an option. See the Easy-Ten ET-SNUL Type S light tension box.
Fitting and use
Fit the tensioner on the slack side of the chain with the roller bearing on the chain. Check the chain tension and the roller at regular maintenance intervals.
