6. To apply tension to the Belts, tighten (turn clockwise) the rear M10 Jam
Nut until the required Belt Tension is achieved. To loosen the Belts, turn
the front M10 Jam Nut counter clockwise until the required Belt Tension
is achieved. (See Figure: C1318P/C1418P Belt Tensioning Jam Nut
Directions). NOTE: Do not over tighten the belts as too tight of belts
can break Engine Output Shafts, Blade Shafts, Belts, and cause
premature Bearing Failures. Failures due to too tight of Belts are not
covered by any warranty. Too loose of Belts will cause the Belts to slip
under load, and may cause burning of the Belts and is not covered under
any warranty.

8. Replace the Belt Guard and replace and tighten the M10 Belt Guard
Retaining Hardware.
9. Run the machine for around 15 minutes and recheck the belt tension. If
the Belts slip under load increase the belt tension.
Remember, too much tension shortens belt and bearing life!
Check the belt tension frequently during the first day of operation. Check the
belt tension periodically thereafter and make any necessary adjustments.
