CAUTION

only. Do not operate machine with guard open.
* DO NOT MIX OLD AND NEW BELTS!
To extend the life of your bearings and
shafts we recommend that you replace all
5 belts when one or more are frayed or
broken. Older belts which have stretched
over time require a different setting than
new belts. To get the right tension on the
old belts you will put too much tension
on the new belt(s) putting undue strain on
shafts and bearings!
