If top cover and pulley cover are balanced (ie. 3/16" x 3/16") or less than 1/16" differential
(
ie. 3/16" x 5/32"), add 6" to the minimum belt width.
Additional break in time is required when the belt has been stored prior to installation in ambi-
ent temperatures of less than 50 degrees Fahrenheit.

Wood Sawyer P/P rated belt tension can exceed 100%, with a maximum of 150%, during starting and stopping conditions.
Fastener size recommendation may vary due to cover thickness.
*
P/P = Polyester/Polyester
**
Average permanent elongation values at 100% of rated belt tension are based on ISO 9856 test procedure. Consult your GTM or GAD for elastic & total elongation calculations specific to each system
based on Minuteman calculations.
