Changing Blades
After changing a blade, the upper and lower
blade support bearings and guide blocks must be
readjusted. Always adjust the guide assemblies
away from the blade before installing a new blade
or making blade adjustments.
To change blades:
1.
Make sure machine is off and unplugged.
2.
Open upper and lower wheel covers.
3.
Remove the fence assembly.
4.
Release tension on the bandsaw blade.
5.
Remove table insert and setscrew from the
table.
6.
Slip blade off wheels and guide it through
the table slot.
7.
To install a new blade, reverse the above
procedure.
After correctly setting blade tension and tracking,
readjust the upper and lower support bearings
and guide block assemblies.
Wear gloves and safety glasses when han-
dling blades. Coiled blades will spring open
as they are uncoiled. Blades are very sharp.
Failure to exercise care may result in seri-
ous personal injury.
