Special care needs to be taken with your Poly Chain

® belt. Alignment, tension, and cleanliness

of this belt are very important. The Poly Chain® belt needs to be checked for tension

approximately every 70 to 100 hours of use. The Poly Chain® belt must be running true. If you

adjust one bearing more than the other, the belt will run on an angle and will cause belt failure.

If a belt is broken straight across, this is the result of a shock load. Lost teeth on the belt are an

indication that the belt was loose. When replacing the Poly Chain® belt, do not try to pry belt on

over sprocket, this can break the fibers in the Poly Chain® belt. After you have installed or re-

tensioned the Poly Chain® belt, you will have to re-adjust the engine belt for proper tension

• Remove the Poly Chain

® guard cover and

bottom cover. The cutter wheel must be

disengaged. (See the Machine Control section

for more information.)

• Loosen, do not remove, the nuts on the bolts

that are holding the belt guard to the machine.
