Adjustment of Belt Tension
Warning
Be sure to stop the engine before adjusting
the belts.
Caution
If you have removed covers, etc., be sure to
securely install them in their original positions.
If covers, etc., remain removed, the operator
may come in contact with rotating parts or
belts, or foreign objects may fly off, possibly
resulting in injuries.
Important
For the specified value of belt tension, refer to
Adjusted Values.
After rotating the belt several times, check that
it has the specified tension.
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.
