Important
Make sure that the belt has the specified
amount of tension.
Before making sure of its specified tension,
rotate the belt several times.
If the belt becomes slack due to frequent use, it
may jump or slip.
In addition, if it is overtightened, it may wear
prematurely.
If necessary, adjust it, and always check the
belt for appropriate tension.
