ONDITION
:
Mark or note a point on the belt. Work your way around the
belt, checking for cracks, frayed spots, cuts or unusual wear
patterns.
Check the belt for excessive heat. While the belt does get hot
during operation, if it is too hot to touch, the cause of the
overheating should be investigated. The hand can tolerate up
to about 60°C (140°F), the maximum temperature at which a
properly maintained belt should operate.
The Belt should be replaced if there are obvious signs of
cracking, fraying or unusual wear.
