Tensioning/
Replacing V-Belts
After approximately 16 hours of opera-
tion, V-belts will stretch and seat into pul-
ley grooves. The V-belts need to be re-
tensioned after this initial break-in peri-
od to ensure optimum power transfer and
maximum overall life of the V-belts.
V-belts transfer power from motor to cutterhead.
To ensure efficient transfer of power to cutterhead,
make sure V-belts are always properly tensioned
and in good condition.
V-belts and pulleys will be hot after opera-
tion. Allow them to cool before handling.

tensioned.
If the V-belts are worn, cracked, or damaged,
replace them. Always replace the V-belts with
a matched set, or belt tension may not be even
among both belts, resulting in sub-optimal power
transfer and premature belt failure.

— If there is approximately
1

" deflection
when V-belts are pushed with moderate
pressure, V-belts are properly tensioned
and no adjustment is necessary. Proceed
to
Step 6.
— If there is not approximately

" deflec-
tion when V-belts are pushed with
moderate pressure, V-belts are not
properly tensioned. Proceed to
Step 4.
4. Loosen hex nuts on motor tension rods
(see
