Checking and
Tensioning V-Belts
To ensure optimum power transmission from the
motor to the blade, the V-belts must be in good
condition and operate under proper tension. The
belts should be checked for cracks, fraying, and
wear. Belt tension should be checked at least
every 3 months—more often if the bandsaw is
used daily.
Tools Needed: Qty
Ruler ...................................................................1
Hex Wrench 6mm ...............................................1
Wrench 17mm.....................................................1
To check V-belts:
1. DISCONNECT MACHINE FROM POWER!
2. Open wheel covers.
3. Note condition of V-belt. If V-belts are cracked,
frayed, or glazed; they should be replaced.
4. Push center of V-belts. Note amount of
deflection (see
Figure 58). If deflection is
more than
3
⁄
4
", tension V-belts.

To tension V-belt:
1. DISCONNECT MACHINE FROM POWER!
2. Open wheel covers.
3. Loosen motor adjustment bolts shown in
Figure 59.
4. Adjust belt tension:
—If belts are too loose, turn tension nut
clockwise to tighten belts.
—If belts are too tight, turn the tension nut
counterclockwise to loosen belts.
5. Push center of the V-belts. If deflection is
approximately
3
⁄
4
" with moderate pressure,
then tension is correct. If deflection is more
than
3
⁄
4
", repeat Step 4.
6. When V-belt tension is correct, tighten motor
adjustment bolts, and close wheel covers.
