Tensioning/
Replacing V-Belt
Tensioning Replacing Belt
To ensure optimum power transmission from
the motor to the cutterhead, the V-belt must be
in good condition (free from cracks, fraying and
wear) and properly tensioned.
After approximately 16 hours of opera-
tion, belts will stretch and seat into pul-
ley grooves. The belts need to be re-ten-
sioned after this initial break-in period
to ensure optimum power transfer and
maximum overall life of the belts.
