Replacing Poly Chain
 Loosen the front jam bolts on the
underside of the boom box and move the
cutter wheel toward the engine as far as
possible. This will loosen the Poly
Chain belt. You will need to loosen
®
the same jam bolt on both bearings.
 NOTE: Keep a count of how many
turns you make on the jam bolts when
you loosen them, making the same
number of turns on both jam bolts.
This makes adjusting the Poly Chain
belt easier when you are finished
changing it. Tighten the jam bolts the
same number of turns as you loosened
them to keep the belt running true.
Use a straight edge to check pulley
alignment when adjustments have
been made.
 Once the belt has been replaced, reverse the procedure to re-assemble the boom. Use
the jam bolts on the cutter wheel bearings to adjust proper tension on the belt making
sure to tighten or loosen them equally, keeping the sprockets aligned. See chart that
follows for tensioning specifications.
 If belt tension needs adjusting, tighten
belt tension by loosening the jam bolts at
the back of the machine. Adjust both
bearings the same amount or belt will
run at an angle and cause breakage.
Loosen jam bolts on both sides the same
amount and readjust the nuts on opposite
side to lock position. Loosen cutter
wheel bearing bolts and pull cutter wheel
toward back of machine to tighten belt,
retighten bolts. Reposition front jam
bolts against cutter wheel bearing and
tighten.
 Replace the Poly Chain
cover and the bottom cover.
 NEVER RUN MACHINE WITHOUT
BELT GUARDS AND COVERS IN
PLACE AND BOLTS TIGHTENED.
