G0668 20" Vertical Metal-Cutting Bandsaw
Redressing Rubber
Tires
As the bandsaw ages, the rubber tires on the
wheel may need to be redressed if they become
hardened or glazed over. Redressing the rubber
tires improves blade tracking and reduces vibra
-
tion/blade lead.
If the rubber tires become too worn, then blade
tracking will become extremely difficult. At that
point, redressing will no longer be effective, and
the rubber tires must be replaced.
To redress the rubber tires:
1. DISCONNECT BANDSAW FROM POWER!
2. Put on heavy gloves and remove the blade.
3. Use a brush and shop vacuum to clean any
chips and built-up oil or sludge from the rub
-
ber tires.
4. Hold a piece of 100-grit sandpaper against
the rubber tire and rotate the wheel by hand.
Only redress the rubber enough to expose a
fresh rubber surface.

Lubrication
The bearings on your bandsaw are factory lubri-
cated and sealed. Merely leave them alone unless
they need to be replaced.
Before lubricating the tension leadscrew or guide
post rack, wipe as much of the old grease off as
possible. The old grease will be contaminated with
metal dust and increase the wear of the metal sur
-
faces. Use mineral spirits or the degreaser shown
in Figure
4 on Page 12 to clean any remaining
grease off, making sure to thoroughly wipe off the
degreaser or mineral spirits that may contaminate
the new grease.
If the table becomes difficult to tilt, position it so
that you use the same process described above
to clean the metal surfaces of the trunnion and
table. Then brush a thin coat of automotive-grade
multi-purpose grease on the trunnion surfaces
(see Figure 40). Tilt the table back and forth to
distribute the grease.

Leadscrew
When the leadscrew and rack are thoroughly clean
and dry, brush a light coat of automotive-grade
multi-purpose grease on the tension leadscrew
and guide post rack to maintain smooth operation
(see Figure 39).
