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.

2. open the left side door, then remove the left
and rear lower access panels.
3. refer to Figure 81 to help identify the loca-
tions of the three motor adjustment hex nuts
and bolts.
4. Check the deflection of the V-belts by apply-
ing moderate pressure midway between the
pulleys, as illustrated in
Figure 82. When
properly tensioned, there should be approxi-
mately a

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.
