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. It is nor-
mal to see a small build-up of rubber dust
during the break-in period.
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.
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.
1. DISCONNECT AND LOCK-OUT MACHINE
AT POWER SOURCE!
2. Open chain drive access door and lower
cutterhead belt cover (see
Figure 85).

when V-belts are pushed with moderate

(see
Figure 85) until there is proper tension
on V-belts. While holding tension lever down,
tighten tension lock lever.
5. Close lower cutterhead belt cover and chain
drive access door.

To reduce risk of shock or
accidental startup, always
disconnect and lock-out
machine from power before
adjustments, maintenance,
or service.
