Blade Changes
To replace the blade:
1. DISCONNECT BANDSAW FROM POWER!
2. Open the upper and lower wheel doors,
release tension on the blade, and move the
blade guides away from the blade.
3. Put on heavy gloves, then slide the blade
off the upper and lower wheels, around the
blade post, and through the table slit.
4. Install a new blade in reverse order.
5. Position the back edge of the blade so that it
is next to, but not against, the flange of the
top wheel (see Figure 18).
All saw blades are
dangerous and may cause
personal injury. To reduce
the risk of being injured,
wear leather gloves when
handling saw blades.
Always disconnect power
to the machine when
changing blades. Failure
to do this may result in
serious personal injury.
!
Note: Excessive blade contact with the wheel
flange during operation could lead to blade
and wheel damage.
6. Re-tension the blade (refer to the following
Blade Tensioning section).
7. Rotate the top wheel clockwise by hand
several times to make sure the blade tracks
evenly without wandering across the wheel
surface.
Note: If the blade wanders across the wheel
and away from the flange, the wheel
alignment may need to be adjusted. Refer
to Blade Tracking on Page 41 for detailed
instructions.
8. Adjust the upper and lower blade guides
(refer to Adjusting Blade Guides on
Page 30).
9. Close and secure the upper and lower wheel
doors.
Blade Tension
To correctly tension the blade:
1. DISCONNECT BANDSAW FROM POWER!
2. Turn the blade tension handwheel until you
feel an moderate amount of resistance and
the handwheel wants to stop. Then turn the
handwheel an additional
1 ⁄
2
turn.
To prolong blade life, release the tension on
the blade if the machine will be idle for an
extended period of time.

Proper blade tension reduces the risk of blade
breakage and improves cutting performance.
