Tensioning/
Replacing v-belts
NOTICE
After the first 16 hours of use, the v-belts
will stretch and seat into the pulley grooves.
The v-belts must be properly re-tensioned
after this period to avoid severely reducing
their useful life.
to ensure efficient transfer of power to the spin-
dle, make sure the V-belts are always properly
tensioned and in good condition.
if a V-belt is worn, cracked, or damaged, replace
both V-belts at the same time to ensure belt ten-
sion is even between them, which reduces the
risk of premature wear on either belt.

— if there is not a 3 ⁄

" deflection of the V-belts,
loosen each of the top adjustment hex
nuts, then raise or lower the motor by turn-
ing each hex nut underneath the motor
mounting plate by the same amount until
the V-belt tension is correct.
5. When you are satisfied that the V-belts are
properly tensioned, make sure all adjustment
hex nuts are tight, then replace the left and
rear lower access panels and secure the left
side door.
