To avoid serious injury or death:

Be sure to stop the engine and remove the key
before checking belt tension.

outward to tighten the belt. After adjustment, securely
tighten the bolts.

1. Loosen the nuts and remove the cover.

2. Moderate belt tension:

The belt should deflect approx. 10 mm when the
center of the belt is depressed with finger pressure of
98 N (10 kgf).
